Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@ClawCall MCP Server Call 555-0199 and check if my order is ready."
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
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.
ClawCall's official remote MCP server is available at:
https://api.clawcall.dev/mcpAdd 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
configure inbound answering and passthrough callers that ring the verified account phone directly with the original caller ID, without recording or transcription
The Grok Build plugin source is in grok/. Its official xAI marketplace submission is tracked in xai-org/plugin-marketplace#336.

Install the ClawCall skill from ClawHub:
openclaw skills install @clawcall-dev/clawcall-devPublished skill: https://clawhub.ai/clawcall-dev/skills/clawcall-dev
Install version 2.0.1 directly from the official repository:
hermes skills install https://raw.githubusercontent.com/ClawCall-Dev/ClawCall/skill-v2.0.1/skill/SKILL.mdOr install the publisher-qualified ClawHub package:
hermes skills install @clawcall-dev/clawcall-devStart a new Hermes session after installation, then ask Hermes to make a call. The direct install exposes /clawcall; the ClawHub install exposes /clawcall-dev. Use CLAWCALL_API_KEY if you already have a key; eligible first calls can provision one. No call is placed during installation.
Hermes' Skills Hub searches ClawHub and other registries. On versions whose ClawHub search returns no results, use either install command above instead of keyword search.
Or copy the skill/ directory, containing only SKILL.md and LICENSE, into your agent's skills directory. The skill fetches current calling guides and API formats from ClawCall's public guide index before new operations. These instructions change with the server without requiring another skill update. Credentials remain local and are never sent when fetching public guides.
Existing installations need the 2.0.0 migration once. Replace the old skill directory, including its bundled references, with the two-file package. Keep credentials in the host secret store or ~/.config/clawcall/key.json. Changes to the skill's capabilities or permissions still require a new skill release.
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.
