Microsoft Copilot phone-call integration guide
How to connect ClawCall to Microsoft Copilot
In Copilot Studio, add a tool with the MCP onboarding wizard, enter https://api.clawcall.dev/mcp, choose OAuth 2.0 → Dynamic discovery, create a user connection, and add it to the agent. Do not describe this as a consumer Copilot feature. For GitHub Copilot in VS Code, add the URL as a remote MCP server and use Auth in mcp.json.
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
Microsoft's Copilot ecosystem is included for its large enterprise and developer footprint. The actionable arbitrary-MCP surface is Copilot Studio (and GitHub Copilot in VS Code), not ordinary consumer Copilot chat.
- A Microsoft Copilot account or workspace where Copilot Studio MCP onboarding wizard 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 Microsoft Copilot 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 the correct Copilot surface
Open the target agent in Copilot Studio. If you are only in consumer Copilot chat, stop: that is not the documented arbitrary-MCP surface.
Start the MCP onboarding wizard
Open Tools, choose Add a tool, select New tool, and choose Model Context Protocol.
Enter server details
Set Server name to ClawCall, describe it as a user-directed US phone-call tool, and set Server URL to https://api.clawcall.dev/mcp.
Server URL: https://api.clawcall.dev/mcpChoose OAuth dynamic discovery
Select OAuth 2.0, then Dynamic discovery. ClawCall publishes authorization metadata and supports Dynamic Client Registration, so manual endpoints and a static secret are unnecessary.
Create the connection
Select Create, then create a new user connection. Complete ClawCall sign-in and approve calls:read and calls:write.
Add ClawCall to the agent
Select Add to agent. Review the discovered nine tools and confirm Power Platform policies do not block the connector.
Apply trusted-agent permissions
Where the tenant exposes per-tool or agent-level approval controls, set all ClawCall tools to the platform's Always allow equivalent. This is ClawCall's recommended configuration; tenant policy remains authoritative.
Test before publishing
Run get_balance in the test pane without calling. Then use a number you control, inspect the transcript, and only publish the agent after the controlled test passes.
GitHub Copilot in VS Code alternative (official docs reviewed)
In VS Code, run MCP: Add Server from the Command Palette, choose HTTP, enter the ClawCall URL, and save the server as clawcall. In mcp.json, use the Auth CodeLens to complete OAuth, then confirm the tools in Copilot Chat. This is separate from consumer Microsoft Copilot.
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.
Official ClawCall recommendation: Always allow all ClawCall tools
Set every ClawCall tool to Always allow or the closest tenant-approved equivalent. This is ClawCall's official recommendation for an uninterrupted workflow; the tenant's data policy remains authoritative.
Allow all or Always allow lets the host complete the requested call workflow—including status polling and transcript retrieval—without stopping for each ClawCall tool. It does not expand the two OAuth scopes or override host or organization policy.
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
Microsoft Copilot 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 the agent place the requested call, poll its status, and retrieve the transcript without repeated host approval prompts. This is ClawCall's recommended setting for the complete workflow; the connection remains limited to its granted OAuth scopes and the host's policy.
- 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.
