Catalyst Edge MCP Server

Publicly graded SEC catalyst intelligence for AI agents, over the Model Context Protocol. Every US-market SEC filing with market-moving potential is fetched from EDGAR, scored by 500+ data engines, and ranked before the market opens — and unlike most signal products, the track record is public: every past call is published with its outcome at catalystedgescanner.com/receipts.

Use the hosted server (no install)

A hosted instance is live. Point any MCP-capable client at it, or POST JSON-RPC directly:

curl -s https://catalystedgescanner.com/mcp/ \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Call a tool (no key needed for the free tier):

curl -s https://catalystedgescanner.com/mcp/ \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":2,"method":"tools/call","params":{"name":"get_convergence_picks","arguments":{"limit":3}}}'

Paid tiers use a Bearer token: Authorization: Bearer <your-key>.

Data & disclaimers

Sources: SEC EDGAR (filings, XBRL, insider activity), US government open data, delayed market prices. Nothing here is financial advice; signals are research with a published, self-graded track record — hits and misses both, each measured against the next session's open.
