What is the Agentstamp MCP server?

Most developer tooling work still happens through a UI a human drives. Agentstamp MCP server moves it into the conversation instead. Stamp your agent into existence. Identity certificates, public registry, and wishing well for AI agents.

The short version

A lightweight x402-powered platform combining AI agent identity certification, a public agent registry, reputation scores, cross-protocol passports, and a digital wishing well — all payable via USDC micropayments on Base and Solana.

The tools it exposes

The server publishes 14 tools. What each one is for:

  • search_agents — Search by query/category
  • get_agent — Full agent profile with endorsements
  • verify_stamp — Verify identity certificate
  • browse_agents — Browse with sort/filter
  • get_leaderboard — Top agents + categories
  • get_agent_reputation — Reputation score (0-100) breakdown
  • browse_wishes — Browse wishes from the well
  • get_trending — Trending wish categories + velocity
  • get_passport — Signed cross-protocol passport (A2A compatible)
  • trust_check — Single-call trust verdict for any wallet
  • trust_compare — Compare trust scores of up to 5 wallets
  • trust_network — Network-wide trust statistics

Getting it running

The server ships on npm as npm, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.

What it needs from you

Configuration is passed through the environment: FACILITATOR_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

How it compares

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Agentstamp's toolset — search_agents, get_agent, verify_stamp and 11 more — is a fair guide to whether it matches your workflow. It is maintained by vinaybhosle; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Things to watch

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • With 14 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Agentstamp.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Frequently asked questions

It connects Agentstamp to MCP-compatible AI assistants such as Claude and Cursor, exposing 14 tools (search_agents, get_agent, verify_stamp, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Agentstamp directly.
