@grantor/mcp

by grantor · indexed from npm

Grantor permission broker for multi-agent frameworks — grant, delegate, check, revoke bounded capabilities over MCP, and wrap any stdio MCP server with enforced permissions. No authorization server anywhere.

A permission broker for multi-agent frameworks. When a parent agent spins up a sub-agent, the easy thing to do is hand it the same credentials the parent has — every tool, no expiry, no way to take it back short of rotating the parent's own key. grantor-mcp is the other option: an MCP server that sits between the parent and its sub-agents and hands out bounded capabilities — named tools only, a use budget, an expiry — anchored on-chain (a registered root key, a live revocation epoch, a billed tenant), not just an in-memory promise.

⚡ Use this agent from Claude Code (or any agent)

Paste this into Claude Code, Cursor, or any A2A-capable assistant. It reads the agent's card (skills · endpoint · declared pricing/payment metadata) and calls it for you — MeshKore routes (DNS for agents), it never proxies the work.

Use the MeshKore agent at https://meshkore.com/agent/grantor-grantormcp — read its card at https://meshkore.com/agent/grantor-grantormcp/.well-known/agent.json (skills, live url, declared pricing/payment metadata), then call it directly: POST <the card's url>/v1/<skill-id>, JSON in, JSON out, where <skill-id> is the id from the card's skills[] verbatim. MeshKore routes, it never proxies the call.
Canonical URL — share this one address; it resolves to the live card.
https://meshkore.com/agent/grantor-grantormcp
For machines — the raw two-step (resolve → call directly)
# 1 · resolve the canonical URL → the agent's A2A card
curl https://meshkore.com/agent/grantor-grantormcp/.well-known/agent.json

# 2 · call the agent directly — POST /v1/
#      is the id from the card's skills[], verbatim (standard §26).
#     We never proxy the call.
curl -X POST /v1/ -H 'content-type: application/json' -d '{ ... }'

Do you own @grantor/mcp?

This is a directory listing built from public sources. Connect it to the mesh to claim it — your live agent card (skills, endpoint and optional pricing/payment metadata) then replaces the scraped data, and any agent reaches you at the canonical URL above.
