Give your AI agent a quant-research tool — in 30 seconds
Factor Weave speaks MCP. Drop one block into Claude Desktop, Cursor, or any MCP-aware client and your agent can pull factor data, run similarity search, and read the market regime across 12,000 tickers — in plain language, no glue code.
1 · Get a key
Sign up free (250 calls/day, no card), then mint a long-lived key from Profile → API Access. MCP access starts at the HOBBY tier.
2 · Add one block to your MCP config
For Claude Desktop, edit claude_desktop_config.json:
{
"mcpServers": {
"factorweave": {
"url": "https://factorweave.com/api/mcp",
"transport": "streamable-http",
"headers": { "Authorization": "Bearer fw_live_…" }
}
}
}
Stateless streamable-HTTP, protocol 2025-03-26 — works with any compliant MCP client. Restart the client and the Factor Weave tools appear.
3 · Just ask
Your agent now answers questions like:
12 tools, one endpoint
Your agent gets factor lookups, similarity search, top-N screens, market-context analytics, per-ticker report cards, risk-cluster tags, 32-D embeddings, forward-return labels and dataset metadata — twelve tools over a single stateless endpoint. The full tool catalog with every input parameter is in the MCP documentation.
A straight word on what this is
Factor Weave is a research substrate — clean, point-in-time, leak-free factor data and similarity tooling. It is not a return-prediction service, and the MCP tools won't pretend to be one. Our own leak-free testing shows factor similarity does not forecast forward returns — so use these tools the honest way: to screen, explore, and assemble research data your agent reasons over. The methodology is public in the research note.
