Marketgenius MCP
Marketgenius provides an MCP server that exposes interactive stock market analysis and visualization tools, including dynamic metric heatmaps, stock quotes, ETF data, macroeconomic statistics, and investment calculators. It allows agents to access live financial data, validate stock codes, and perform calculations without authentication.
Endpoint and access
No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.
https://marketgenius.app/mcpWhat its tools do
17 tools, grouped by the hints the server advertises. Hints are self-declared, not verified behavior.

mg_list — List Marketgenius Tools
List all available Marketgenius tools with their names, descriptions, categories, and resource URIs. Use mg_list to discover what's available, or filter by category.

}mg_calculator_cagr — CAGR Calculator
Open the CAGR Calculator React MCP App UI. ALWAYS ask first — never call this tool silently: "Open the calculator directly, or pre-fill it with your inputs?" IF directly → call this tool now with no params. STOP. Do not ask anything else. IF pre-fill → collect only the input schema fields — do not guess or invent field names.

}mg_calculator_cagr_update — CAGR Calculator — Update
Update one or more fields in the already-open CAGR Calculator. ALWAYS call mg_calculator_cagr_state first — the user may have changed values manually in the GUI and you must not overwrite them. Pass the version you received from that call (or from the open tool if updating immediately after opening). Only pass the fields the user explicitly asked to change; omit all others. Send all changes in a single call — multiple sequential calls lose intermediate updates (only the last one applies).
