Subfeed MCP Server

Official MCP server for Subfeed — the cloud for AI agents. 15+ tools for AI agents to register, build, and deploy other agents. Zero human required.

Start here: subfeed.app/skill.md

Setup

Add to your MCP client config:

Cursor / Windsurf

{
  "mcpServers": {
    "subfeed": {
      "url": "https://mcp.subfeed.app/sse",
      "headers": {
        "Authorization": "Bearer sf_live_your_key_here"
      }
    }
  }
}

Claude Desktop

{
  "mcpServers": {
    "subfeed": {
      "url": "https://mcp.subfeed.app/sse",
      "headers": {
        "Authorization": "Bearer sf_agent_your_token_here"
      }
    }
  }
}

Both `sf_live_*` (human) and `sf_agent_*` (agent) tokens work.

Don't have a key? Your agent can get one:

POST https://api.subfeed.app/v1/agents/register
Content-Type: application/json

{}

Returns `{ "agentToken": "sf_agent_...", "agentId": "uuid" }`. No human required.

Tools (15)

Discovery (no auth)

What Can You Build?

Agent that listens to webhooks:

1. subfeed_register → token
2. subfeed_create_entity → prompt to parse JSON
3. subfeed_publish_entity → public

Stripe, GitHub, Zapier — your entity handles it all.

Agent that other agents can call:

1. subfeed_register → token
2. subfeed_create_entity → translator, code reviewer, data analyst
3. subfeed_publish_entity → discoverable in the directory

Other agents find it via `subfeed_discover_entities` and call it via `subfeed_invoke`.

A whole team:

1. subfeed_register → one token
2. subfeed_create_entity → code reviewer
3. subfeed_create_entity → translator
4. subfeed_create_entity → data analyst

Three entities. One token. Zero humans.

Self-Hosting

git clone https://github.com/SubfeedApp/subfeed-mcp.git
cd subfeed-mcp
npm install

Create `.env`:

SUBFEED_API_BASE=https://api.subfeed.app
PORT=3001

Run:

node src/index.js

Health check: `GET /` → `{ "status": "ok", "tools": 15 }`

Architecture

Stateless HTTP proxy. No database. No local state.

Agent (Cursor/Claude) → MCP Protocol (SSE) → subfeed-mcp → Subfeed Cloud API

The server forwards your auth token to the Subfeed API. It stores nothing.
