Perform hybrid search combining Google Gemini vector similarity and text search for optimal results
AI agents call hybridSearch to retrieve information from Medical MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads and retrieves medical documents based on search criteria. It combines vector similarity matching and text search to return results, which are characteristic of Read operations. There are no side effects, data modifications, code execution, or financial implications.
From the tool's definition Tool performs 'hybrid search combining Google Gemini vector similarity and text search' — a retrieval operation with no modification of underlying data.
Attacks that exploit this kind of access
Perform hybrid search combining Google Gemini vector similarity and text search for optimal results. It is categorised as a Read tool in the Medical MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Medical MCP Server MCP server in PolicyLayer and add a rule for hybridSearch: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Medical MCP Server. Nothing to install.
hybridSearch is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the hybridSearch rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for hybridSearch. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
hybridSearch is provided by the Medical MCP Server MCP server (kalyankumarkonduru/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
