Subfeed
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.

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

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.
