io.github.ClawCall-Dev/clawcall — MCP Server for Developer Tools

ClawCall

Make real AI-powered phone calls from any AI agent. ClawCall dials US phone numbers, handles the conversation, and returns the outcome, transcript, and recording when available.

30 calls and 30 minutes free, whichever lasts later. No credit card required.

Hosted MCP connector (recommended)

ClawCall's official remote MCP server is available at:

https://api.clawcall.dev/mcp

Add that URL as a custom connector in Grok Build, ChatGPT, Claude, Codex, or another remote MCP client. The connector uses OAuth 2.1: sign in to ClawCall and approve read/write call access when prompted. No API key is copied into the AI host.

The hosted connector can:

place outbound calls to US phone numbers
navigate phone menus and hold queues
bridge the user into a live call
poll call status and retrieve transcripts and temporary recording URLs
list inbound and outbound call history
end active calls and inspect plan or trial usage
serve ClawCall's calling guide before a call is placed

The Grok Build plugin source is in grok/. Its official xAI marketplace submission is tracked in xai-org/plugin-marketplace#336.

Agent skill

Install the ClawCall skill from ClawHub:

openclaw skills install clawcall-dev

Published skill: https://clawhub.ai/clawcall-dev/clawcall-dev

Or manually add skill/SKILL.md and its bundled references to your agent's skills directory. The skill uses ClawCall's REST API and persists its low-privilege API key locally.

Legacy local stdio MCP package

The mcp/ directory contains the legacy @clawcall/mcp stdio package for existing local/API-key installations. New integrations should use the hosted OAuth connector above. The legacy package remains documented for compatibility but is not the distribution path submitted to the xAI marketplace.

What it does

Calls US phone numbers over real phone lines
Handles appointments, reservations, order checks, callbacks, office follow-ups, phone menus, and hold queues
Leaves voicemail or takes messages when instructed
Returns call outcomes, transcripts, and recordings
Supports live handoff when identity verification, negotiation, or a real-time decision requires the user
Supports reusable voice, personality, greeting, and inbound reserved-number answering preferences through the product and REST surfaces

Examples

"Call Dr. Rivera's office and confirm my appointment for Tuesday at 2:30."

"Phone the restaurant at +15551234567 and make a reservation for four people Saturday at 7 PM."

"Get me through to a real person at my insurance company."
