Setting Up Arcade Scope

Setting up Arcade scope

Scope is the org, project, and (where curated gateways exist outside an all-apps-only deployment) gateway a hub call runs against. Every account picks this exactly once: the very first hub tool call it ever makes returns a blocking setup prompt instead of running, and that prompt must be answered before anything else can proceed. After that one prompt, the choice is persisted and invisible — never surface it again unless the user explicitly asks to change org, project, or gateway.

Arcade_Project lives on the arcade MCP server.

Quick start

Arcade_Project(action: "list")                        # current + available org/project/gateway choices
Arcade_Project(action: "set", target: "...", scope?)  # change org/project/gateway (id from list)

Recognizing the setup prompt

Any hub tool call (Arcade_SelectTools, Arcade_UseTool, Arcade_Apps, Arcade_Project) can return one of these instead of doing what you asked:

• "status": "select_gateway" — scope isn't set yet. The response's message field already says exactly what to do (ask the user, then call Arcade_Project with their pick) — follow it. projects[] lists the choices grouped by project, each with a gateway id and display name.
• "status": "no_gateways" — nothing can be resolved at all (no apps available to the account). message says this is an account-setup gap that only the Arcade dashboard (or whoever manages the account) can fix — no Arcade_Project call will help. Relay that plainly and stop.

Both are ordinary (non-error) tool results, not a special pause type — treat them as "the tool needs one more piece of information before it can run."

Presenting the choices

1. Show the choices by name — project names and gateway/app-bundle names — never raw ids (gateway values are ids, name values are what to show).
2. Get the user's actual pick. Never guess or auto-select on their behalf, even if there's an obvious single choice — a one-item list is still a choice for the user to confirm, not one to skip past.
3. Call Arcade_Project(action: "set", target: "<id from the choices>").
4. Retry the original call you were making (the same Arcade_SelectTools / Arcade_UseTool / etc. call, unchanged) — it now resolves normally. Don't mention scope again unless the user brings it up.

Example

Arcade_SelectTools(tasks: ["Send a message to #eng saying the deploy is done"])
  → {status: "select_gateway",
     message: "Before running anything, ask the user which set of apps to
               use. List the options below grouped by org/project and wait
               for their choice, then call Arcade_Project with the chosen
               target. Do not guess.",
     projects: [{project: "Engineering",
                 gateways: [{gateway: "full-suite", name: "Full Suite", apps: [...]}]}]}
Present the choice → user picks "Full Suite" →
Arcade_Project(action: "set", target: "full-suite")
  → {target: "full-suite", name: "Full Suite", message: "Connected to Full Suite: ..."}
Retry the original call:
Arcade_SelectTools(tasks: ["Send a message to #eng saying the deploy is done"])
  → normal results

Changing org, project, or gateway later

Only when the user explicitly asks ("switch my project", "use the other org", "change my gateway") — never speculatively.

1. If the target is ambiguous, call Arcade_Project(action: "list") first and match the user's words against the names it returns — never guess an id. list groups choices by org, then project, each with an "all apps in this project" target plus any curated gateways.
2. Call Arcade_Project(action: "set", target: "...") with the id from list. Add scope: "everywhere" only if the user wants the change to apply account-wide instead of just this app (default this_app).
3. Relay the confirmation (message in the response) so the user knows the new scope took effect.

The change takes effect on the next tool call — no restart or reconnect.

Errors

• Unknown org/project/gateway name → list and match by name; never guess.
• action: "set" refused as "pinned" → this deployment fixed the scope itself; tell the user it can't be changed here.
• Gateway not offered by list → that account's deployment may not have curated gateways configured (e.g. an all-apps-only deployment) — org and project selection still apply, gateway just isn't part of this account's choice.

When NOT to use

• Never call Arcade_Project speculatively during normal task execution. Scope is automatic and persists after the one mandatory prompt — don't call list or set before ordinary tasks "just in case."
• Only act on this flow when a tool call actually returns select_gateway / no_gateways, or when the user explicitly asks to change their org, project, or gateway.
• Performing tasks inside an app — that's using-arcade-tools.
• Managing app connections/sign-ins — that's managing-arcade-apps.

Style

• Scope language: org, project, gateway, "set up", "change" / "switch". Show names prominently; ids only as the value passed to target.
• Don't dump the raw list output — summarize with names, and mark whichever choice is currently active.
