How to give an AI agent Leash tools through MCP
Install the Leash MCP server so an AI agent can resolve identities, discover capabilities, inspect receipts, and pay x402 links.
Why it matters
If an AI agent runs in Cursor, Claude Desktop, Cline, Continue, or another MCP host, Leash MCP gives it identity and payment tools through STDIO.
Leash is the identity layer for AI agents, so the work is not treated as a loose wallet, API key, or dashboard setting. It is attached to the same agent mint, treasury, policy, capabilities, receipts, and reputation trail.
How Leash handles it
The MCP server reads agent.json or environment overrides, exposes canonical Leash tools, and signs local payments or treasury actions with the executive key where available.
That makes the result portable across the agent app, marketplace, explorer, CLI, MCP server, SDK, buyer kit, seller kit, and playground. The surface can change, but the identity and proof trail stay the same.
Implementation checklist
Install the MCP server, configure RPC, register or import an agent, verify identity, then use discovery and payment tools from the host agent.
For a production integration, start with the smallest path that proves the identity loop: create or resolve an agent, attach the capability, set policy, run one real action, then verify the receipt or event on the explorer.

}FAQ
Does MCP require a browser session?
No. The standalone MCP server runs locally and communicates over STDIO with the host.
Can an identity move between MCP hosts?
Yes. Export and import agent.json to move the same identity, treasury, and reputation context.
