Stamp your agent into existence. Identity certificates, public registry, and wishing well for AI agents.
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.
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 server publishes 14 tools. What each one is for:
search_agents — Search by query/categoryget_agent — Full agent profile with endorsementsverify_stamp — Verify identity certificatebrowse_agents — Browse with sort/filterget_leaderboard — Top agents + categoriesget_agent_reputation — Reputation score (0-100) breakdownbrowse_wishes — Browse wishes from the wellget_trending — Trending wish categories + velocityget_passport — Signed cross-protocol passport (A2A compatible)trust_check — Single-call trust verdict for any wallettrust_compare — Compare trust scores of up to 5 walletstrust_network — Network-wide trust statisticsThe 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.
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.
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We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
