Documentation Overview
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:
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:
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
