Dex Personal CRM

Dex is a personal CRM that helps users maintain and nurture their professional relationships. It tracks contacts, interaction history, reminders, and organizational structures (groups, tags, custom fields).

Setup — Detect Access Method

Check which access method is available, in this order:

1. MCP tools available? If dex_search_contacts and other dex_* tools are in the tool list, use MCP tools directly. This is the preferred method — skip CLI setup entirely.
2. CLI installed? Check if dex command exists (run which dex or dex auth status). If authenticated, use CLI commands.
3. Neither? Guide the user through setup.

If you can run shell commands but cannot open a browser — you are a sandboxed-compute agent (Grok Bot, OpenClaw, and similar hosted agents that execute on their own machine rather than the user's). Don't expect the host's own MCP connector sign-in to work: its form takes only a URL and static headers, so it never starts an OAuth flow and reports authentication_required with no link to hand the user. Start with Path B (install the CLI) followed by the device code flow below — that terminates in the user signing in on their own device.

Once the device flow has issued a dex_ key, you have both options. Keep using the CLI, or — if the user prefers MCP tools over CLI commands — add https://mcp.getdex.com/mcp as a connector with that key as an Authorization: Bearer dex_… header. Tool calls work either way.

Before you take the connector path, read this — the rule is here, not only in Authentication. A dex_ key carries no scopes: it acts as the user across their whole account and it does not expire, unlike the scoped one-hour OAuth token. Never print it, echo it into chat, or place it in a tool argument the user can see. Nothing in this paragraph relaxes that. If wiring the connector would require you to surface the key anywhere at all, stop and ask the user to mint their own key at Settings → Integrations and paste it into the host's connector field themselves.

The host may still label the connector "unauthenticated" because it tracks OAuth state it never established. That badge on its own is cosmetic — but a 401 or 403 on a tool call is a real failure (revoked key, or an account without a Professional subscription), not a display quirk. Judge by whether tool calls actually succeed, and surface a rejection instead of retrying it.

First-Time Setup

Path A — Platform supports MCP with OAuth (Claude Desktop, Cursor, VS Code, Gemini CLI, etc.):

This path requires a client that implements the MCP OAuth spec — it must be able to follow a WWW-Authenticate challenge and open a browser or hand the user an authorize URL. A host that only accepts a server URL plus a static Authorization header (Grok Bot, the xAI API remote-MCP tool) cannot complete it; use Path B instead.

If the user already has the Dex MCP server configured, or their platform can add MCP servers:

npx -y add-mcp https://mcp.getdex.com/mcp -y

This auto-detects installed AI clients and configures the Dex MCP server for all of them. User authenticates via browser on first MCP connection.

Path B — Install CLI:

npm install -g @getdex/cli

Works with npm, pnpm, and yarn. No postinstall scripts — the binary is bundled in a platform-specific package.

Keeping the CLI up to date:

The CLI auto-generates commands from the MCP server's tool schemas at build time. When tools are added or updated on the server, users need to update the CLI to get the new commands. If a user reports a missing command or parameter, suggest updating:

npm install -g @getdex/cli@latest

Path C — No Node.js:

Direct the user to follow the setup guide at https://getdex.com/docs/ai/mcp-server — it has client-specific instructions for Claude Desktop, Claude Code, Cursor, VS Code, and other MCP-capable clients.

Authentication

Triggered by /dex-login or on first use when not authenticated. Prefer MCP browser OAuth when your host supports it, then device code for an interactive CLI session or any sandboxed-compute agent, and API keys for CI or when the user explicitly chooses one.

On Grok Bot, OpenClaw, and similar hosted agents, device code is the first choice, not the fallback — there is no browser on your machine to open, but the user has one on theirs.

Do not trust dex auth status alone. Status is green if any credential file exists. Verify with a real command such as dex dex-list-tags. A 401 unauthorized after a "successful" login almost always means the CLI is still reading a stale token.

Where credentials actually live:

• @getdex/cli reads ~/.clihub/credentials.json (auth_type: bearer_token, token: dex_…).
• Some docs and older agents only write ~/.dex/api-key. That file is not what the CLI sends on MCP calls.
• After device-code or API-key setup, write both files, or the next dex … call will 401.

Cloudflare: every request to mcp.getdex.com must send User-Agent: dex-cli. Bare curl with no UA returns Cloudflare 1010 (browser_signature_banned). That is not an expired code and not a Dex 401.

Never ask the user to paste an API key into chat. Do not print, log, commit, or include it in tool arguments that will be shown back to the user. dex auth --token <key> puts the secret on the process argv — do not run that from an agent.

Option 1 — API Key:

1. User generates a key at Dex Settings > Integrations (requires Professional plan)
2. Ask the user to save it in their own terminal, or write both files below from a local script that never prints the value
3. Destinations: ~/.dex/api-key (chmod 600) and ~/.clihub/credentials.json (chmod 600)

Option 2 — Device Code Flow (works on remote/headless machines):

Drive this flow directly via HTTP — no browser needed on the machine. Always send User-Agent: dex-cli.

1. Request a device code:

   curl -s -X POST https://mcp.getdex.com/device/code \
     -H "Content-Type: application/json" \
     -H "Accept: application/json" \
     -H "User-Agent: dex-cli"
   

   Response: { "device_code": "...", "user_code": "ABCD-EFGH", "verification_uri": "https://...", "expires_in": 600, "interval": 5 }

2. Show the user the user_code and verification_uri. They open the URL on any device with a browser, log in to Dex, and enter the code.

3. Poll for approval every 5 seconds without logging the successful response:

   curl -s -X POST https://mcp.getdex.com/device/token \
     -H "Content-Type: application/json" \
     -H "Accept: application/json" \
     -H "User-Agent: dex-cli" \
     -d '{"device_code": "<device_code>"}'
   

   • HTTP 200 + {"error": "authorization_pending"} → keep polling (this is not success)
   • HTTP 429 + {"error": "slow_down"} → wait longer than interval
   • HTTP 400 + {"error": "expired_token"} → request a new device code
   • HTTP 403 Cloudflare 1010 → add User-Agent: dex-cli and start over
   • HTTP 200 + api_key → stop polling. Do not print the body.

4. Save the key to both locations without printing it:

   install -d -m 700 ~/.dex ~/.clihub
   umask 077
   

   • ~/.dex/api-key — raw dex_… bytes, mode 600, no trailing commentary
   • ~/.clihub/credentials.json — mode 600, this schema (CLI source of truth):

   {
     "version": 2,
     "servers": {
       "https://mcp.getdex.com/mcp": {
         "type": "bearer",
         "auth_type": "bearer_token",
         "token": "<api_key>"
       }
     }
   }
   

   If the execution surface cannot keep the successful /device/token response out of chat or tool logs, stop and ask the user to finish in their own terminal.

5. Verify with dex dex-list-tags (or another read). If that 401s, ~/.clihub/credentials.json was not updated.

There is no dex auth login subcommand in current @getdex/cli (1.0.x) even if some READMEs mention it. Use this HTTP device flow.

For CI/automation with no human present, use the API key method with DEX_API_KEY environment variable and the credentials file above.

Using Tools

MCP Mode

Call dex_* tools directly. All tools accept and return JSON.

CLI Mode

Use the dex command. CLIHub generates subcommands from MCP tool names (replacing _ with -):

dex dex-search-contacts --query "John"
dex dex-list-contacts --limit 100
dex dex-create-contact --first-name "Jane" --last-name "Doe"
dex dex-list-tags
dex dex-create-reminder --text "Follow up" --due-at-date "2026-03-15"

Use --output json for machine-readable output, --output text (default) for human-readable.

Run dex --help for all commands, or dex <command> --help for command-specific help.

See CLI Command Reference for the full mapping table of all 53 tools to CLI commands.

Core Workflows

1. Find a Contact

choose search/filter/list → get details (with notes if needed)

• Use dex_search_contacts for keywords or real geographic proximity with near and optional radius_km
• When using near, keep query for an additional non-location filter; do not repeat the place in both fields
• Use dex_filter_contacts for structured AND filters such as tags, groups, company, profile presence, dates, archived state, and custom fields
• Use dex_list_contacts for unfiltered bulk iteration (up to 500 per page, cursor-paginated)
• Use an empty search query to browse a single batch of contacts sorted by most recent interaction
• Include include_notes: true when user needs interaction history

2. Add a New Contact

create contact → (optionally) add to groups → apply tags → set reminder

• Create with whatever info is available (no fields are strictly required)
• Immediately organize: add relevant tags and groups
• Set a follow-up reminder if the user just met this person

Bulk import (CSV, spreadsheet, list):

batch create contacts → add to group → create note for all

• Use dex_create_contact with the contacts array (up to 100 per call) for batch creation
• Use the returned contact IDs to add them all to a group with dex_add_contacts_to_group
• Use dex_create_note with contact_ids to log a shared note across all imported contacts

3. Log an Interaction

(optional) list note types → create note on contact timeline

• Discover note types first with dex_list_note_types to pick the right one (Meeting, Call, Coffee, Note, etc.)
• Set event_time to when the interaction happened, not when logging it
• Keep notes concise but capture key details, action items, and personal context
• Use contact_ids (plural) to link a single note to multiple contacts (e.g. a group meeting)

4. Manage Follow-Ups

set cadence or create reminder → complete/snooze when due

• Use dex_update_contact.keep_in_touch for relationship cadence; use a reminder for a specific task
• Always require due_at_date (ISO format: "2026-03-15")
• Use text for the reminder description — there is no separate title field
• Recurrence options: weekly, biweekly, monthly, quarterly, biannually, yearly
• Use dex_complete_keep_in_touch without snooze_days after a real interaction; use snooze_days to defer without recording a touch

"What's coming up?" — for any question about the near future ("whose birthday is next week?", "who should I reach out to this week?", "what do I have coming up?"), call dex_list_upcoming_reminders_and_birthdays rather than stitching several lists together. One call returns birthdays, open reminders and keep-in-touch contacts for a window (default 7 days, days: 30 for a month).

• It reports turning_age ONLY when the birth year is known. A birthday with no year returns neither birthday_year nor turning_age — say the date, never a guessed age
• Its keep_in_touch list DOES include people already overdue (is_overdue: true); its reminders list does NOT include overdue reminders — get those from dex_list_reminders with is_overdue: true
• On a wide window, check reminders_truncated / keep_in_touch_truncated before telling the user that is everything

5. Organize Contacts

Tags — flat labels for cross-cutting categories:

create tag → add to contacts (bulk)

Groups — named collections with emoji and description:

create group → add contacts (bulk)

Best practice: Use tags for attributes ("Investor", "Engineer", "Met at Conference X") and groups for relationship clusters ("Startup Advisors", "Book Club", "Acme Corp Team").

6. Manage Custom Fields

list fields → create field definition → batch set values on contacts

• Three field types: input (free text), autocomplete (dropdown with options), datepicker
• Use dex_set_custom_field_values to set values on multiple contacts at once
• For autocomplete fields, provide categories array with the allowed options

7. Meeting Prep

When a user says "I have a meeting with X":

1. Search for the contact
2. Get full details with include_notes: true
3. Check recent reminders for pending items
4. Optionally search relevant email correspondence and fetch the calendar event when the user asks for live context
5. Check dex_get_contact_research for a stored web research note; offer dex_research_contacts (paid, slow) when there is none and the user wants public background
6. Summarize: last interaction, key notes, pending follow-ups, shared context, attendees, recent correspondence, and cited web findings
7. See CRM Workflows for detailed meeting prep guidance

8. Manage Calendar Events

• Use dex_list_calendar_events for a time window or plain-text event search across all connected Google/Microsoft accounts
• Reuse an event's returned email as account_email for get/update/delete
• For get/create/update/delete, also pass account_provider when the same address is connected to both providers
• For timed events, provide both start_datetime and end_datetime with explicit offsets; include an IANA timezone
• For all-day events, provide start_date; end_date is exclusive and defaults to the next day
• Confirm before creation when attendees may receive invitations
• On update, attendees replaces the whole list; fetch the event first and include everyone who should remain
• A recurring series ID updates the whole series; state that scope before confirmation
• For calendar create/update, generate idempotency_key before the first attempt and reuse it with identical arguments only to retry that operation within 24 hours. Every new edit or intended new event needs a new key. Without one, update executes again; create deduplicates identical content for 24 hours, so use a new key when recreating a deleted event or intentionally creating another identical event. This does NOT generalise: dex_create_contact, dex_create_group, dex_create_tag and dex_create_custom_field carry a fresh key per call, so a retry of those duplicates. dex_create_note and dex_create_reminder are safe to retry only when you pass your own idempotency_key — reuse the SAME key and the same arguments, within the server's 24-hour window, and the original row comes back instead of a duplicate. dex_create_note additionally requires an explicit event_time whenever idempotency_key is present (it is rejected otherwise), because a defaulted "now" would differ on every attempt and defeat the replay. Set event_time yourself when you intend to retry.

An update cannot move an event between connected accounts. To transfer one, fetch the original, confirm creating a replacement on the target account, then separately confirm deleting the original. Preserve the full attendee list and details, and warn that organizer identity, RSVP state, conferencing data, and provider notifications may change.

If a calendar list returns warnings, describe the results as incomplete; do not infer availability from the missing accounts. If all calendars fail, report the error rather than saying there are no meetings.

If a calendar write fails for missing provider scope, direct the user to Settings → Sync & Integrations → Grant calendar access for that account.

9. Search Correspondence

• Use dex_search_emails for live, read-only search across all connected Google/Microsoft mailboxes
• To list recent mail, omit query; use folder: 'inbox' for received mail. Follow next_cursor while keeping the same folder and date bounds
• Use plain keywords such as a name, company, domain, or topic; provider operators such as from: and to: are neutralized
• Set after and before for precise date ranges; otherwise the search covers roughly the last six months
• Results contain metadata, snippets, and provider links, not full bodies
• Dex cannot send email; do not imply that this tool drafts or sends messages

10. Research a Contact on the Web

• dex_get_contact_research reads the stored note for up to 10 contacts at no cost — check it first
• dex_research_contacts runs Dex Research for up to 5 contacts per call: a paid web search + page extraction + LLM summary that takes a minute or more per contact. Confirm with the user before running it on more than a couple of contacts
• Notes under 30 days old are served from cache; pass force: true only when the user explicitly wants a fresh run
• A fresh run replaces the stored research note and its finding statuses. Preserving existing contact fields does not preserve the previous research note; explain that replacement before forcing a rerun
• Quote findings with their citations ([[n]] markers resolve into sources) and mention identity_confidence when it is not high
• A run fills empty linkedin / website fields itself only from high-confidence findings, reported in applied; it never overwrites an existing value. A lower-confidence linkedin/website finding comes back pending, exactly like every email and phone finding — check each row's status rather than assuming a field was filled. Anything pending needs the user's confirmation, then dex_update_contact to apply it
• in_progress means another request is already researching that contact: read it back later instead of running again

11. Archive, Delete, or Merge

Prefer reversible cleanup:

1. Use dex_archive_contacts for contacts the user may want later
2. Find archived contacts with dex_filter_contacts and archived_only: true
3. Restore them with dex_archive_contacts and archived: false

For duplicates:

search for potential duplicates → confirm with user → merge

• Dex chooses the oldest record in each group as the survivor, regardless of input order
• Read mergedContactIds from the response to learn which ID survived
• Always confirm with the user before merging (destructive operation)
• Can merge multiple groups in a single call

12. Handle Outcome-Oriented Requests

For multi-contact or multi-step requests, follow this reusable contract:

define scope → inspect current state → preview proposed outcome → confirm writes → execute → verify

• Treat requests to analyze, recommend, audit, or prepare as read-only unless the user also asks for changes
• When the user says “all,” paginate the complete relevant dataset and state whether the scope includes active contacts, archived contacts, or both
• Reuse existing tags, groups, custom fields, contacts, and recent notes before creating anything
• Separate high-confidence actions from ambiguous records that need review
• Present exact additions, updates, removals, archives, merges, notes, and reminders before bulk writes
• Verify changed records with fresh reads and report successes, skips, and failures

Load CRM Workflows for detailed playbooks when the user asks to:

• Categorize or reorganize their whole network
• Turn a notetaker summary or transcript into notes, contact updates, and reminders
• Audit or clean up CRM data
• Import and follow up with people from an event or roster
• Review relationship health or plan outreach
• Prepare a day or week of meetings
• Build a target contact list from several criteria

Important Patterns

Privacy and Data Minimization

• Retrieve only the fields and history needed for the request; leave include_notes and include_contacts off unless relationship context is necessary
• Treat contact methods, notes, email snippets, attendee lists, and provider links as private relationship data
• Summarize relevant context instead of repeating unnecessary personal details
• Never share or transmit Dex data to another service without an explicit user request
• Do not claim access to full email bodies when dex_search_emails returns only metadata and snippets
• Present web research as cited public information, not as facts Dex verified; surface identity_confidence when the note may describe a different person

Pagination

Only responses with has_more and next_cursor use cursor pagination:

• dex_list_contacts: default 100 per page, max 500
• dex_filter_contacts: default 50 per page, max 200
• Tag, group-contact, note, and reminder lists: default 10 per page
• Check has_more in response
• Pass next_cursor as cursor while preserving the original filters, sort order, and optional includes
• Iterate until has_more: false to get all results

dex_search_emails listings (without query) also paginate, with default 25 and maximum 100 messages per page. Searches with query are a single page and reject cursor.

dex_search_contacts and dex_list_calendar_events return a bounded single batch, not a cursor. Narrow the query or date range when necessary.

Destructive Operations

Respect MCP host confirmations. In CLI mode, explicitly summarize the target and consequence before any operation that deletes, overwrites, removes relationships, archives, completes cadence state, changes external calendar state, or may send invitations.

High-risk examples:

• Contact deletion, merge, and bulk archive
• Any update that overwrites saved fields or replaces a collection
• Removing tags or group memberships
• Completing/snoozing keep-in-touch state
• Deleting groups, tags, notes, reminders, or custom fields
• Setting custom field values in bulk
• Creating, updating, or deleting calendar events
• Running paid web research (dex_research_contacts) on more than a couple of contacts, or with force: true

Before a destructive call, resolve names to current IDs, read the current record when overwriting a collection, show the intended delta, and never guess ambiguous targets.

For contact cleanup, do not define “stale” from inactivity alone. Review open reminders and active relationship signals, present exact archive/retain lists, and require approval before archiving or changing cadence. Date filters exclude contacts with no recorded interaction, so review those separately when they matter.

Response Truncation

Responses are capped at 25,000 characters. Cursor-based tools preserve next_cursor and has_more; continue with a smaller page. For single-batch search, calendar, and email tools, reduce limit or narrow the query/date range.

Date Formats

• All dates: ISO 8601 strings (e.g., "2026-03-15", "2026-03-15T14:30:00Z")
• Birthdays: YYYY-MM-DD when the year is known, or --MM-DD when only the month and day are. Dex stores the year in a separate column, so a birthday that reads back as --MM-DD means the year was never recorded — do not substitute the current year, and do not report one.
• Reminder due dates: YYYY-MM-DD
• Calendar timed events: ISO 8601 with an explicit UTC offset plus an IANA timezone
• Calendar all-day end_date: exclusive
