Perplexity phone-call integration guide
How to connect ClawCall to Perplexity
Ask a Perplexity Enterprise admin to add a custom remote connector named ClawCall at https://api.clawcall.dev/mcp, use OAuth discovery/Dynamic Client Registration, and enable it for the intended workspace. Sign in, verify get_balance, then make a controlled call. Consumer Perplexity without custom remote connectors is not a direct hosted-MCP path.
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
Perplexity is included because it appears across major web and mobile AI-product rankings and documents custom remote MCP connectors with OAuth for managed Enterprise workspaces.
- A Perplexity account or workspace where Enterprise custom remote connector 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 Perplexity 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.
Confirm Enterprise eligibility
Ask the workspace admin to confirm Custom Remote Connectors is enabled. Do not confuse Perplexity's built-in connectors with an arbitrary remote MCP connector.
Create a custom remote connector
From the workspace connector administration surface, choose the custom remote connector flow and name the connector ClawCall.
Add the MCP endpoint
Use https://api.clawcall.dev/mcp as the Streamable HTTP server URL. Do not paste a ClawCall API key into connector settings.
https://api.clawcall.dev/mcpUse OAuth discovery
Keep OAuth discovery and Dynamic Client Registration enabled. Complete ClawCall sign-in and review calls:read and calls:write.
Scope workspace access
Publish or enable the connector only for the intended members or Spaces. Review any workspace tool allowlist before rollout.
Apply the official permission recommendation
If Perplexity offers server or tool approval persistence, choose Always allow/Allow all for ClawCall after the administrator and user review the eleven tools.
Verify and call
Run get_balance first. Then call a number you control and require transcript evidence actually captured before treating the task as complete.
OAuth scopes and host permissions
A compatible host discovers ClawCall's authorization-server and protected-resource metadata, dynamically registers a public client, and completes OAuth 2.1 authorization code with PKCE S256. It receives revocable tokens—never your ClawCall API key—and the consent flow requests two bounded scopes:
calls:readRead plan/trial state, call settings, reserved-number status, call status, captured transcript evidence when present, history, and temporary recording access when available.
calls:writePlace and hang up real phone calls or update call settings when you ask the assistant to do so.
Official ClawCall recommendation: Always allow all actions
For an approved Enterprise workspace, set ClawCall to Always allow or Allow all wherever Perplexity exposes that control. This is ClawCall's official recommendation for the complete calling workflow.
Allow all or Always allow lets the host complete the requested call workflow—including status polling and nullable 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 any transcript evidence actually captured afterward.
The 11 ClawCall tools
Read the transcript evidence actually captured 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. |
get_call_settings | Read | Read reusable voice/personality, reserved-number capabilities, and inbound-assistant availability. |
update_call_settings | Write | Update global or inbound call settings in separate calls. |
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 nullable bounded transcript tail. |
get_call_transcript | Read | Read the transcript evidence captured 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 eleven 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 the nullable transcript field.
A recording link no longer works
Recording URLs are temporary. get_recording returns the original link and cannot renew it after expiry. ClawCall deletes transcripts 7 days after a call ends and recordings 10 minutes after a call ends.
Disconnect and revoke access
Perplexity 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 captured transcript evidence when present 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 transcript evidence actually captured 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.
