Overview

AI-generated overview

CAI MCP gives AI agents a custodial crypto wallet, a @cai.com email address and a vault, installed as a local stdio server.

What you can do
  • Manage an agent identity with a custodial wallet, @cai.com email inbox and vault
  • Handle payments and wallet operations on the agent's behalf
  • Look up the provider's skill contract and agent card for usage guidance
  • Run locally as a stdio process launched through npx
When to use it
Consider it when you want an AI agent to hold its own identity, receive email and make or receive payments without wiring up separate wallet and mail services.
Requirements
A local Node.js runtime, since it is installed globally from the @cailab/mcp npm package and launched with npx. An API key supplied in the CAI_API_KEY environment variable. Desktop MCP client only; no remote or web endpoint.
Before you install
The wallet is custodial, so funds and keys are held by the provider rather than by you. The setup requires a CAI_API_KEY secret in the client configuration. The server can move money and send or receive email, and account data is shared with the provider's service.

Installation

In SourceWeft

  1. Open CAI MCP in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

Score

40% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
