Best Finance & market data MCP servers

Finance MCP servers give an agent access to market and financial data — crypto prices and market caps, stock quotes and fundamentals, economic indicators, and banking or platform diagnostics. With them an agent can answer a portfolio question with live numbers, pull a ticker's history into an analysis, or check on-chain market data without you wiring up the API. The thing to weigh is the data source and its limits: each server rides a specific provider, so coverage, freshness, and rate limits follow that upstream, and many gate richer data behind a paid key. Most are keyed stdio or hosted remote servers; some crypto data endpoints are even keyless for basic queries. Treat any server that can move money or read private accounts with extra care.
