OpenClaw is the fastest growing agent harness out there, which can work 24/7 to automate almost any kind of tasks. However, its capabilities are limited to the tools it has access to. Composio allows your OpenClaw to access Callerapi with authentication management handled for you. You can execute actions on Callerapi via your favorite OpenClaw interface (Telegram, WhatsApp, TUI, etc), whichever you prefer.

Why use Composio?
Apart from a managed and hosted MCP server, you will get:
- Programmatic tool calling allows LLMs to write its code in a remote workbench to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling.
- Handling Large tool responses out of LLM context to minimize context rot.
- Dynamic just-in-time access to 20,000 tools across 850+ other Apps for cross-app workflows. It loads the tools you need, so LLMs aren't overwhelmed by tools you don't need.
How to install Callerapi with OpenClaw
Using Composio API Key and Setup Prompt
- Go to dashboard.composio.dev/composio/~/connect/clients/openclaw
- Copy the setup prompt
- Run it in your OpenClaw chat interface.
- Authenticate Callerapi from the dashboard
- Go back to your OpenClaw interface and start asking questions.
Using OpenClaw/Composio Plugin
1. Install OpenClaw Composio plugin
2. Copy the API Key from dashboard.composio.dev
3. Setup OpenClaw Config
openclaw config set plugins.entries.composio.config.consumerKey "ck_your_key_here"4. Restart OpenClaw
openclaw gateway restart5. Go to your chat interface and start asking questions.
6. When prompted, authenticate the app and you're all set.
How It Works
The plugin connects to Composio's MCP server at https://connect.composio.dev/mcp and registers all available tools directly into the OpenClaw agent. Tools are called by name — no extra search or execute steps needed.
If a tool returns an auth error, the agent will prompt you to connect that toolkit at dashboard.composio.dev.

What is the Callerapi MCP server, and what's possible with it?
The Callerapi MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Callerapi account. It provides structured and secure access to caller identification and reputation data, so your agent can perform actions like verifying phone numbers, checking caller reputation, retrieving business and carrier details, and monitoring account usage on your behalf.
- Detailed phone number lookup: Instantly retrieve information about any phone number, including reputation, business association, carrier, and FTC complaints.
- Reputation and fraud assessment: Empower your agent to check if a phone number might be flagged for spam, robocalls, or fraud, helping you screen and validate callers.
- Business and carrier identification: Have your agent fetch in-depth business and carrier details for a given number to strengthen trust and context in communications.
- HLR (Home Location Register) checks: Enable your agent to request HLR data for deeper carrier and number status insights, including ported or roaming status.
- Account usage monitoring: Let your agent access your Callerapi user profile to monitor credit usage, monthly allocations, and remaining balance, keeping you informed about your API consumption.

FAQ
What are the differences in Tool Router MCP and Callerapi MCP?
With a standalone Callerapi MCP server, the agents and LLMs can only access a fixed set of Callerapi tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Callerapi and many other apps based on the task at hand, all through a single MCP endpoint.
Can I use Tool Router MCP with OpenClaw?
Yes, you can. OpenClaw fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Callerapi tools.
Can I manage the permissions and scopes for Callerapi while using Tool Router?
Yes, absolutely. You can configure which Callerapi scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.
How safe is my data with Composio Tool Router?
All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Callerapi data and credentials are handled as safely as possible.
