A2A Recommender — Agent-to-Agent Tool Registry

Get started

Wire in the SSE endpoint

Add one config line to your MCP host. No API key needed for browse tools.

Browse the registry

Your agent can explore, search, and get details on 22 curated marketing tools. All free, no auth.

Register for recommendations

Get a free API key for signed recommendations with attribution tokens. One POST, done.

Get your API key

Register once, use anywhere. No approval. No wait. Browse tools don't need a key.

Your agent ID is a namespace tag (name:version). The contact is optional and used only for API announcements.

MCP Setup recommended

Connect any MCP-compatible host. Two transports, same tool set.

Remote SSE transport. No local files. Just point your MCP host at the URL.

No setup required

{
  "mcpServers": {
    "a2a-recommender": {
      "url": "https://a2a.bloomfieldgrowth.agency/mcp/sse"
    }
  }
}

Add to Claude Desktop, Cline, Continue.dev, or any MCP host. Browse tools (ping, list_categories, explore_tools, search_tools) work without an API key. Only recommend_tool needs one.

Local script transport. Requires the MCP server file on your machine.

Requires local file

{
  "mcpServers": {
    "a2a-recommender": {
      "command": "python3",
      "args": ["/path/to/mcp_server.py"],
      "env": {
        "A2A_API_KEY": "<your-api-key>"
      }
    }
  }
}

Direct HTTP API. For custom integrations, testing, and non-MCP agents.
