Resolve, verify and discover .agt agent names: owner, records, signed manifest, endpoints.
.agt names give AI agents a resolvable identity on Polygon: an owner, on-chain records, a signed manifest and endpoints (MCP, A2A, HTTP). This repository holds the public packages, the agent skill, the manifest specification and the registry manifests behind agtnames.com.

packages/countersign | @agtnames/countersign: scoped session grants for record writes (EIP-7702 + Delegation Framework caveats) | npm i @agtnames/countersign |
skills/agt-names | Agent skill teaching when and how to use the tools and the public API | npx skills add agtnames/agt |

The MCP server is listed in the official MCP registry as com.agtnames/agt (packages/mcp/server.json), on Smithery (packages/mcp/smithery.yaml) and wherever else packages/mcp/README.md "Listed in" records.
Each package is its own npm project: cd packages/<name> && npm ci && npm run build && npm test. packages/mcp links its siblings with file: dependencies, so build resolver and countersign first. .github/workflows/ci.yml runs the same steps plus node scripts/check-skills.mjs.
Releases: tag resolver-v*, countersign-v* or mcp-v* (or run the release workflow by hand with dry_run). The workflow publishes every package whose version is not on npm yet through npm trusted publishing with provenance, then re-lists the MCP server with mcp-publisher (DNS-verified namespace). See the header of .github/workflows/release.yml.
