iVolatility market data in any MCP client: option chains, IV surface/IVX/skew, greeks, NBBO, earnings
Project description
mcp-ivolatility-data
iVolatility market data MCP server for local use by data-oriented clients
(quants with their own Claude, Cursor, or any MCP client). One package ships
the engine (ivol_mcp_core) and the bundled endpoint index, and runs the tools
(search_endpoints → call_api → query_data) against the iVolatility REST API.
No hosting — the client installs it locally and uses their own IVOL_API_KEY.
Access control stays on the REST API (tariff/limits by key).
Install
uv tool install mcp-ivolatility-data
claude mcp add ivolatility -e IVOL_API_KEY=<key> -- mcp-ivolatility-data
Or any mcp.json-style client (Cursor, …): command: mcp-ivolatility-data,
env: {IVOL_API_KEY: <key>}. uv brings its own Python — the client does not
install Python manually. Claude Desktop users: prefer the .mcpb bundle
(double-click install, key form) or the remote connector URL.
What it covers
65 endpoints: full REST (equities/futures EOD+intraday, RT REST, fixed income,
curves) from the bundled OpenAPI spec, plus /account/access and WebSocket
discovery from the prompt supplement. (RT market-wide screeners intentionally
excluded.)
