Which AI clients work today?

Claude Desktop, claude.ai, and ChatGPT — anywhere that supports the Model Context Protocol (MCP) standard. Add Callmine as a connector and complete the OAuth flow.

What can the AI client do once connected?

Read your reports, list and inspect schedules, preview analyses, start analyses (with an extra confirmation step), and read your workspace audit log. Nineteen tools total, all prefixed `callmine_`.

Does the AI client get to spend my quota without asking?

No. Starting an analysis requires a two-step preview-then-start handshake. The AI client must call preview first, get a short-lived confirmation token, then start the run with the token. This prevents accidental runs from a single prompt.

Where does the AI client authenticate?

Through Callmine's normal Clerk sign-in. The MCP server runs an OAuth 2.1 + PKCE flow that drops you on `app.callmine.ai/sign-in`; once you authorize, the AI client gets a scoped access token bound to your workspace.

How do I connect Callmine to Claude, ChatGPT, or other AI clients?

Connect Callmine to Claude Desktop, claude.ai, or ChatGPT in a few clicks. 19 tools, OAuth 2.1 sign-in, scoped to one workspace.

TL;DR

Callmine exposes an MCP server at mcp.callmine.ai with 19 tools covering reports, schedules, audits, and analysis runs. Add it as a connector in Claude Desktop, claude.ai, or ChatGPT; complete the OAuth flow once; ask the AI to do work in your Callmine workspace.

How it works

MCP (Model Context Protocol) is the open standard for connecting AI clients to external tools. Callmine ships a compliant MCP server that runs over HTTPS at mcp.callmine.ai.

When you add Callmine as a connector:

01The AI client redirects you to Callmine's OAuth flow.
02You sign in with Clerk (same login as the web app).
03You authorize the AI client to act on a specific workspace.
04The MCP server issues a scoped access token bound to your identity and that workspace.

From then on, the AI client can call any of the 19 tools on your behalf. Tokens refresh transparently — once set up, you don't see the auth flow again until you explicitly revoke.

The 19 tools

The tool catalog covers four areas:

·Identity and configuration — read your workspace profile, prompt library, audit log, and cost history.
·Reports — list, search, and read past reports.
·Analyses — preview filters, start new runs, check job status, cancel running jobs.
·Schedules — list, inspect, create, activate, pause, resume, and delete schedules.

Read-only tools fire immediately. Mutating tools (start analysis, create schedule, delete schedule) write to your workspace audit log with source: mcp so the action is traceable.

The preview-then-start guard

Starting an analysis is the only tool with a two-step handshake. The AI client must first call callmine_preview_analysis to get a short-lived confirmation token, then call callmine_start_analysis with that token. This prevents a single misinterpreted prompt from burning quota.

The confirmation token is single-use, expires in 5 minutes, and is bound to the exact configuration that was previewed. Changing the config requires a fresh preview.

Adding Callmine as a connector

The connector URL is the same for every client:

https://mcp.callmine.ai/mcp

The OAuth flow is identical regardless of client — paste the URL, sign in with your Callmine credentials, approve the scopes, done. The differences below are just where each app puts the "add connector" button.

Claude Desktop

01Open Settings → Connectors → Add custom connector.
02Name it Callmine and paste https://mcp.callmine.ai/mcp as the server URL.
03Save. Claude Desktop opens a browser tab to Callmine's sign-in.
04Sign in with your normal Callmine account and click Approve on the consent screen.
05Back in Claude Desktop, ask "What Callmine plan am I on?" to confirm the connection.

claude.ai

01Go to Settings → Connectors → Add custom connector.
02Paste https://mcp.callmine.ai/mcp as the server URL and give it a name (e.g. Callmine).
03Click Connect — claude.ai opens the Callmine sign-in flow in a new tab.
04Sign in and approve the scopes.
05The connector appears in your connector list as connected. Start a new chat and Callmine tools are available.

ChatGPT

01In ChatGPT, open Settings → Connectors → Add custom connector (available on Plus, Pro, Team, and Enterprise plans).
02Paste https://mcp.callmine.ai/mcp and pick a display name.
03ChatGPT opens the Callmine sign-in flow.
04Sign in, approve the scopes, return to ChatGPT.
05Toggle the Callmine connector on for the conversation, then ask it to do something — e.g. "List my last five Callmine reports."

After connecting

The first call to any tool consumes the access token; from then on the AI client refreshes silently. You'll only see the auth flow again if you revoke the connection (or if you reconnect from a new device).

Every mutating tool call — starting an analysis, creating a schedule, deleting a schedule — writes to /audit with source: mcp, so workspace admins can always see what the AI did.

Disconnecting

To revoke a connector, remove it from the AI client's connector settings. The MCP-side token is invalidated on the next call. Workspace admins can also revoke all MCP grants for the workspace by emailing hello@callmine.ai.

Troubleshooting

·Sign-in loop or "session invalid" after authenticating. Clear cookies for callmine.ai and try again, or sign in to app.callmine.ai first in the same browser, then re-run the connector setup.
·"Confirmation required" when asking the AI to run an analysis. Expected. The AI must preview before starting — ask it to "preview the analysis first, then start it" and it will chain the two tools.
·The AI says it doesn't see Callmine tools. Make sure the Callmine connector is enabled for the current chat in your AI client's chat-level connector toggles. Setting up the connector at the workspace level doesn't always enable it per chat.

For anything else, email hello@callmine.ai with the AI client name and the exact error message you saw.
