Tools you get
Endpoint checked 2026-10-09: https://figurewell-api.cybermaxtools.com/mcp answered an MCP initialize (protocol 2025-06-18) and tools/list with 3 tools, all marked read-only. No key was used and no tool was called.

|---|---|---|
financials_as_of | A company's 10-K/10-Q/20-F/40-F filings (newest accepted first, up to 40) with revenue, profit, EPS, cash, debt, cash flow and margins as each filing first reported them, EDGAR acceptance time and filing link. as_of = only filings accepted by then. | none |

metric_history | One metric per period, newest first: value as first reported (and when), latest value known at as_of, restated flag. | none |
Test the endpoint from a terminal
This lists the tools without a key and without calling any of them:
curl -s https://figurewell-api.cybermaxtools.com/mcp \
-H 'content-type: application/json' \
-H 'accept: application/json, text/event-stream' \
-d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'If it does not work
- Custom connectors connect from Anthropic's cloud, not your computer; our servers are public, so no allowlisting is needed.
- Free plans can add one custom connector.
- To change the URL or header, remove the connector and add it again.
- The free tier has a daily limit (see the pricing line above); a paid key raises it.
