Cursor phone-call integration guide
How to connect ClawCall to Cursor
Open Cursor Customize and add a custom MCP server, or add a `clawcall` entry with `url: https://api.clawcall.dev/mcp` to mcp.json. Authenticate when Cursor opens OAuth, confirm the tools under Available Tools, and leave the server tool allowlist empty to allow all tools. Cursor automatically uses available MCP tools when relevant.
Setup is based on the cited first-party host documentation; exact ClawCall compatibility is not claimed as live-tested.
https://api.clawcall.dev/mcpBefore you start
Cursor is included because independent reporting and AI-product rankings show major coding-agent adoption, and Cursor documents remote MCP URLs, OAuth, automatic tool selection, and server-level tool allowlists.
- A Cursor account or workspace where Customize / mcp.json is available.
- A ClawCall account or, for a documented fallback, a trusted server-side runtime.
- A real US destination in +1 E.164 format for any call you choose to place.
- A clear, user-directed task with destination and decision boundaries specified before a real call.
Connect Cursor to ClawCall
These steps use the cited host documentation. Screenshots appear only where the signed-in flow was live-verified; text and commands remain the complete guide.
Open Cursor MCP settings
Open Customize and the MCP server section. Choose the custom-server path rather than installing an unrelated marketplace entry.
Add the remote URL
Create a server named clawcall with only the remote URL. No API-key header or static OAuth object is required because ClawCall supports DCR.
{"mcpServers":{"clawcall":{"url":"https://api.clawcall.dev/mcp"}}}Authenticate
Enable the server and follow Cursor's OAuth prompt. Sign in to ClawCall and review calls:read and calls:write.
Review Available Tools
Confirm all nine tools appear. Check MCP Logs if the server is disabled, blocked, or returns an authentication error.
Allow every ClawCall tool
Cursor's team allowlist is an admin control. For trusted use, leave the ClawCall tool allowlist empty so every tool is allowed, and choose Always allow when execution approval is offered.
Verify automatic selection
Ask for get_balance without naming the tool. Cursor can use MCP tools under Available Tools when relevant; manual selection is optional.
Place a controlled call
Call a number you control, then ask Cursor to poll status and read the complete transcript.
OAuth scopes and host permissions
A compatible host receives revocable OAuth tokens, never your ClawCall API key. The consent flow requests two bounded scopes:
calls:readRead plan and trial state, call status, transcripts, history, and temporary recording access.
calls:writePlace and hang up real phone calls when you ask the assistant to do so.
Recommended Cursor setting: allow all ClawCall tools
Leave the ClawCall server tool allowlist empty to allow every discovered tool, and choose Always allow for execution approvals after review. This is ClawCall's official recommendation for a trusted user or administrator-approved workspace.
Cursor can act across code, terminals, and phone tools. Inspect project-level mcp.json before trusting it, and never commit OAuth tokens or secrets. Limit calls to explicit user-directed tasks.
Always allow removes repetitive host prompts; it does not expand OAuth scopes, bypass host or organization policy, authorize spam or robocalls, increase service limits, or turn ClawCall into a bulk campaign tool.
Verify read-only, then place one controlled call
Start with account state. Only after that succeeds should you use a number you control for the first real call.
Check my ClawCall plan and remaining trial allowance. Do not place a call.
Using ClawCall, call my phone at +1XXXXXXXXXX. Say this is a connector test, ask me to confirm I can hear the AI, then end the call. Show me the complete transcript afterward.
The 9 ClawCall tools
Read the transcript before declaring success. A call's outcome describes the phone network; it does not prove the user's task was completed.
| Tool | Access | What it does |
|---|---|---|
get_calling_guide | Read | Required before any ClawCall work. Read current workflow guidance and examples before placing calls. |
get_balance | Read | Read the signed-in account's plan and remaining trial allowance. |
place_call | Write | Start one real outbound phone call and return immediately. |
place_call_and_wait | Write | Start one call and wait up to 90 seconds for an initial result. |
get_call | Read | Read a call's lifecycle, outcome, and a bounded transcript tail. |
get_call_transcript | Read | Read the complete transcript for a call. |
list_calls | Read | Read recent call history for the connected account. |
get_recording | Read | Get a temporary, playable recording URL when one is available. |
hangup_call | Write | Stop a queued or live phone call. |
Troubleshooting
The server returns 404 or no tools appear
Confirm the server URL is exactly https://api.clawcall.dev/mcp; the trailing /mcp is required. Refresh or reconnect after correcting it.
You see 401 or Sign in required
Restart the host's Connect, Auth, or MCP login flow and approve ClawCall access again. Do not replace OAuth with a pasted ClawCall API key.
The tool list looks stale
Refresh or restart the MCP connection, then start a new conversation so the host loads current tool metadata. The current server exposes nine tools.
A phone number is rejected
ClawCall currently calls real US numbers only. Use +1 E.164 format: +1 followed by ten digits.
The wait ended while the call is still running
Ask the host to poll get_call. A host or tool wait cap is not itself a call failure; verify lifecycle, outcome, and transcript.
A recording link no longer works
Recording URLs are temporary. Request a fresh URL with get_recording; treat the transcript as the durable result.
Disconnect and revoke access
Cursor and ClawCall FAQ
- Do I need to choose ClawCall before every request?
- No. Once a compatible connection is enabled, the agent can select ClawCall automatically when an ordinary prompt requires a phone call. A tool picker or explicit tool name is useful for diagnosis, not a mandatory ritual.
- Why does ClawCall recommend Always allow or Allow all?
- It lets a trusted agent place the requested call, poll its status, and retrieve the transcript without repeated host approval prompts. This is an elevated-risk choice because real calls can affect people and consume plan allowance.
- Does a successful network outcome prove the task succeeded?
- No. A network outcome describes the call path. Read the full transcript before claiming a reservation, cancellation, price, or other real-world task was completed.
- How do I revoke access?
- Remove or disconnect ClawCall in the host, then open ClawCall Dashboard → Settings → Connected AI assistants → Disconnect to revoke that connection's token family.
