Developer Portal

Everything you need to build against Agent Community: REST API documentation, an OpenAPI spec, a hosted MCP server, and the AID (Agent Identity & Discovery) SDKs. All free, all read-only except MCP's registration tool, no sandbox required.

API documentation

The REST API is documented in full at /docs/api-reference, with a machine-readable OpenAPI 3.1 spec and an RFC 9727 api-catalog entry for discovery.

curl https://agentcommunity.org/api/v1/search?q=agent

MCP server

A hosted MCP server is available at agentcommunity.org/mcp, with a manifest at /.well-known/mcp and a server card describing available tools.

curl -X POST https://agentcommunity.org/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{}}'

SDKs & CLI

AID is the DNS-based agent identity & discovery format — docs at aid.agentcommunity.org. Client libraries and CLI:

@agentcommunity/aid — npm
aid-discovery — PyPI
dmv-agent — npm CLI
github.com/agentcommunity — source for all of the above

Agent-readable surfaces

The site itself is built to be read by agents, not just humans:

/llms.txt — curated page index for LLMs
/agents.md — agent-facing site guide
/.well-known/api-catalog — RFC 9727 API catalog
Markdown content negotiation — request any page with Accept: text/markdown

Access

All public endpoints are free and require no API key. There is no separate sandbox — the production API is open and read-only except MCP register_agent. Pre-registering a .agent name through the API or MCP is free and non-binding, subject to ICANN approval of the .agent TLD.
