Analysis summary

Yahoo Finance MCP is an officially published MCP server from Yahoo Finance. Anomity scores its risk at 10 out of 100 (low).

An official remote MCP server for stock data, market news, and company financials, giving an agent read access to public market information without an API key management burden.

Outbound network access is the only declared capability, and the data is public, so this is among the lowest-risk entries in the catalog. As with any news-bearing tool, the content is written by third parties and reaches the model as text — an agent that summarises market news is summarising documents that could contain instructions, which matters only if that agent also holds capabilities worth abusing.

Why this entry scored 10 out of 100

This profile starts at the catalog's neutral base of 50. Because the entry is officially published, trust adjusts the score by -40. The entry declares no high-risk capabilities on its own, so capabilities add nothing. It matches no dangerous capability combinations. The clamped result is 10, placing it in the low band.
