Factory Setup

Factory Setup

Bootstrap Warp Factory access for a coding agent that is not Warp itself: install/authenticate the oz CLI, register the hosted Factory MCP server, verify the connection, and hand off to the canonical operating skill. This is a one-time setup skill, not the operating playbook.

Scope

This skill:

1. Detects the target harness (Claude Code, Codex, Cursor, or generic MCP client).
2. Installs/authenticates the CLI and mints an API key.
3. Registers the Factory MCP server for that harness.
4. Verifies the connection (tools visible, list_factories works, canonical skill readable).
5. Optionally helps pick or create a factory and save it as the default.
6. Stops and hands off to the server-served operating skill for everything after setup.

This skill does not:

• Duplicate the day-2 operating playbook — that lives at skill://warp/factory-mcp/SKILL.md on the MCP connection itself and is the authoritative source once connected.
• Automate Slack, Linear, or GitHub integration OAuth for a factory. Point the user at the Factory web app for those; do not attempt to script them here.

Step 1 — Pick a server root

The Factory MCP is always mounted at {server_root}/api/v1/mcp/factory. Third-party harnesses do not know Warp's server root on their own, so make it explicit up front:

• If the machine already sets FACTORY_MCP_URL, use it verbatim instead of building one.
• If it sets WARP_SERVER_ROOT instead, build the URL as {WARP_SERVER_ROOT}/api/v1/mcp/factory.
• Otherwise use https://app.warp.dev — do not ask the user to pick a server root, and do not point them at any other host.
• If registering or calling the MCP URL fails with a not-found/disabled-feature style error, tell the user Factory MCP isn't turned on for their account yet and stop — don't guess around it or substitute a different host.

Step 2 — Get the CLI and an API key

Warp's CLI ships as oz through soft launch; it is renamed to warp at GA. Mention this once so the user isn't confused if they see the CLI called warp elsewhere later.

• Installing oz: the install command is not finalized yet.

  PLACEHOLDER — do not invent a command here. Ask the user how they installed/would install oz, or point them at https://docs.warp.dev for the current instructions. Do not guess a package name, curl-pipe URL, or script.

Once the CLI is available and logged in (oz login), mint an API key for the harness to use:

oz api-key create --expires-in 30d "factory-setup"

Treat the printed key as a secret: export it to an environment variable (e.g. WARP_API_KEY) and use that variable everywhere below. Never paste it into a config file that gets committed, and never print it back to a shared terminal or log.

API key + Authorization: Bearer is the supported auth path and works on every harness. Use it everywhere below. OAuth is not available for third-party clients today: Factory MCP does not support dynamic client registration, and no per-harness OAuth client is registered for external use — so a client's built-in "connect with OAuth" flow will fail. If a harness tries OAuth on its own and fails, fall back to the API key rather than debugging the OAuth flow.

Step 3 — Detect the harness and register the MCP server

Substitute {mcp_url} = {server_root}/api/v1/mcp/factory from Step 1, and $WARP_API_KEY from Step 2.

Claude Code

claude mcp add --transport http warp-factory {mcp_url} \
  --header "Authorization: Bearer $WARP_API_KEY"

Flag names can shift between Claude Code versions — run claude mcp add --help first if this fails. Verified against @anthropic-ai/claude-code (mcp add --transport http ... --header "...") as of this writing.

Do not use claude mcp login / --client-id here — see the OAuth note in Step 2.

Codex

codex mcp add warp-factory --url {mcp_url} --bearer-token-env-var WARP_API_KEY

This writes a [mcp_servers.warp-factory] block to ~/.codex/config.toml with url and bearer_token_env_var; Codex reads the bearer token from that environment variable at connect time, so make sure WARP_API_KEY is exported in the same shell/session Codex runs in. Verified against @openai/codex (mcp add <name> --url ... --bearer-token-env-var ...).

Do not use --oauth-client-id / codex mcp login here — see the OAuth note in Step 2.

Cursor

Cursor has no MCP CLI; edit ~/.cursor/mcp.json (global) or .cursor/mcp.json (project-scoped):

{
  "mcpServers": {
    "warp-factory": {
      "url": "{mcp_url}",
      "headers": {
        "Authorization": "Bearer ${env:WARP_API_KEY}"
      }
    }
  }
}

Cursor resolves ${env:VAR} references in headers from its own process environment at connect time — never inline the raw key in this file, since a project-scoped .cursor/mcp.json is easy to commit or expose. Make sure WARP_API_KEY is actually set in Cursor's launch environment: a shell-only export in .bashrc/.zshrc is not always inherited by a desktop app launched outside that shell, so prefer launching Cursor from a terminal where echo $WARP_API_KEY already prints the value, or set it somewhere Cursor's launcher reliably reads (e.g. /etc/environment on Linux). Restart Cursor after editing, then check Settings → Tools & MCP for a green connection.

Use the headers block above, not an auth block: Factory MCP has no dynamic client registration, so Cursor's discovery/DCR fallback will fail — see the OAuth note in Step 2.

Generic / any other MCP-capable client

Any client that supports streamable HTTP with custom headers can connect directly: point it at {mcp_url} with header Authorization: Bearer $WARP_API_KEY. There is no special Warp-specific transport.

Step 4 — Verify

From the harness with the MCP server attached:

1. List tools (tools/list or the client's equivalent) and confirm the Factory tools are present: list_factories, create_factory, list_tasks, search_task, get_task, message_foreman, get_conversation, send_task, complete_task, list_notification_routes.

2. Call list_factories. Success is any response without an auth error — an empty list just means the principal has no factories yet, which is fine.

3. Read the resource skill://warp/factory-mcp/SKILL.md. A successful read proves the handoff to the operating skill works. Day-2 Factory use depends on this operating skill, so if the harness can't do resources/read itself (some tool-only clients don't), don't just tell the user to "fetch it manually" — fetch it yourself with one standalone JSON-RPC call against the same authenticated endpoint (verified: this works without a prior initialize handshake) and put the returned text somewhere the agent will read it before starting real Factory work:

   curl -s {mcp_url} \
     -H "Authorization: Bearer $WARP_API_KEY" \
     -H "Content-Type: application/json" \
     -H "Accept: application/json, text/event-stream" \
     -d '{"jsonrpc":"2.0","id":1,"method":"resources/read","params":{"uri":"skill://warp/factory-mcp/SKILL.md"}}'
   

   The skill text is in result.contents[0].text of the returned JSON.

If any step fails, stop and report the exact error instead of guessing a fix — see Troubleshooting below.

Step 5 — Optional: pick or create a factory

Setup is complete once Step 4 passes; this step is optional follow-up, not the success bar.

• If the user already has a factory, use list_factories to find its factory_uid and, if they want, save it as their default per the operating skill's ~/.warp/factory/config.json contract (skill://warp/factory-mcp/references/factory-config.md).
• If they want a new factory, create_factory needs team_uid, name, code_forge, and at least one repositories entry (owner/repo); integrations is optional. Avatars are REST-only, not settable over MCP.
• Connecting Slack, Linear, GitHub, or Jira integrations for a factory is out of scope here — send the user to the Factory web app for that; do not try to script integration OAuth from this skill.

Step 6 — Hand off and stop

Once verified, tell the user setup is done. Day-2 operation — finding tasks, delegating work, pulling a task down locally, coordinating with the foreman, handing work back — is governed entirely by the canonical skill the server exposes at skill://warp/factory-mcp/SKILL.md. Read and follow that skill for anything after this point; do not reimplement its operating rules here.

Troubleshooting

• 404 / feature-disabled-looking error at the MCP URL: Factory MCP is not enabled for the user's account yet. Report that and stop; it is not a skill bug, and no other host is a valid substitute.
• 401 Unauthorized: the API key is missing, wrong, or expired. Recreate it (Step 2) and re-register.
• OAuth client not found / OAuth flow rejected / DCR failure: expected — Factory MCP has no OAuth client registered for third-party harnesses. Use the API key path from Step 2 instead of debugging the flow.
• resources/read for the skill URI fails or is unsupported: some clients don't implement MCP resources. The tool surface still works, but fetch the canonical skill yourself with the standalone curl call in Step 4 rather than leaving the user without it.
