Use Callboard from Claude
Ask the booking question where you already work. The Callboard connector lets Claude run a Promoter Brief, check on it, and read your brief history — under your account, against your plan’s allowance.
Who can use it
The connector is included on the Buyer and Company plans. Anyone can add it and sign in; on other plans Claude will tell you it’s not included and point you to pricing.
It works in claude.ai, Claude Desktop, the Claude mobile apps, and Claude Code — and in ChatGPT on paid plans (see ChatGPT below).
Connect
Your connector URL is:
https://api.callboard.fm/mcpclaude.ai, Claude Desktop, mobile
- Open Settings → Customize → Connectors and choose Add custom connector.
- Name it Callboard, paste the URL above, and leave the OAuth fields empty. Click Add, then Connect.
- Sign in to Callboard when the browser asks and approve access. You’re connected to the same account you use on the web.
Claude Code
claude mcp add --transport http callboard https://api.callboard.fm/mcpThen run /mcp inside Claude Code to sign in.
ChatGPT
ChatGPT uses a different connector URL — the same server over its SSE form:
https://api.callboard.fm/sse/- Custom connectors require a paid ChatGPT plan (Plus or higher) with Developer mode enabled: Settings → Connectors → Advanced → Developer mode.
- Add a connector with the URL above, no client ID or secret, and sign in to Callboard when asked.
- Ask ChatGPT to search your briefs or pull one up — it reads them with citations back to your brief pages.
On Plus and Pro, custom connectors are read-only: ChatGPT can search and read your briefs but not run new ones. Running briefs from ChatGPT requires a Business or Enterprise workspace with developer mode.
What Claude can do
| Tool | What it does |
|---|---|
get_account | Your plan and how many briefs are left this period. |
run_brief | Starts a Promoter Brief for an artist + market question. Uses one brief from your allowance. |
get_brief_job | Progress of a running brief; the memo, the full brief, and the link when it finishes. |
get_brief | Reads a finished brief by id — the same sections your plan unlocks on the web. |
list_briefs | Your recent briefs (your whole team's on Buyer and Company), with optional artist or market filters. |
search_artists | Resolves which act you mean when a name matches more than one artist. |
get_watchlist | The artists you're watching. |
Everything except run_brief is read-only. Claude groups them that way in its permission settings; you can leave the read-only tools on Always allow and keep run_brief on Needs approval so a brief is never spent without you saying so.
How a brief runs
A brief takes about five minutes — the same analysis you get on the web, with the same data. Claude starts it, checks back every 45 seconds or so, and hands you the memo when it lands: verdict first, then the why, then a link to the full brief in your history.
If the question needs more (which Wet Leg did you mean? which city?), Claude will ask and run again. Those attempts don’t count against your allowance; neither does a run that fails.
Phrase it the way you’d ask a colleague: “Should I book Wet Leg in Denver in October? 1,500-cap room.” A venue, date, or capacity is optional and helps.
What Claude sees
Only what your account can see on the web: your briefs (and your team’s on Buyer and Company), your watchlist, and your plan’s allowance. The connector signs in through Callboard’s normal login; Callboard never sees your Claude conversations, and Claude only receives what a tool returns.
Disconnect any time from the same Connectors page. Revoking access there stops Claude’s access immediately.
Troubleshooting
- Claude says a tool doesn’t exist. Claude caches the tool list. Open the connector in Settings and choose Refresh tools list.
- “Not signed in” or access errors. Disconnect and reconnect the connector; sign in with the account that holds your plan.
- “Included on the Buyer and Company plans.” Your account is on a plan without the connector. See pricing, or ask your team owner to add you.
- A brief seems stuck. Ask Claude to check the job again. If a server restart interrupted it, the next check reports that and the brief is not charged.
FAQ
Does this use extra briefs? No. A brief run from Claude is the same brief, from the same monthly allowance, and shows up in your history.
Can my teammates use it? Yes — each teammate connects with their own login. Briefs draw from the shared team pool, as on the web.
Is there an API key? Not yet. The connector signs in with your Callboard login. API access is on the Company roadmap.
