Query a running search server directly (without HTTP). Supports semantic, keyword, and hybrid search modes.
AI agents call indexfoundry_serve_query to retrieve information from IndexFoundry MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves search results from an existing vector database search server. Query operations are inherently read-only—they retrieve or match data without side effects. No creation, modification, deletion, execution, or financial operations are indicated. The most severe applicable category is Read.
From the tool's definition Tool description states 'Query a running search server directly' and 'Supports semantic, keyword, and hybrid search modes.' The name and function indicate data retrieval operations typical of search queries, with no mention of modifications, deletions, or…
Attacks that exploit this kind of access
Query a running search server directly (without HTTP). Supports semantic, keyword, and hybrid search modes. It is categorised as a Read tool in the IndexFoundry MCP MCP Server, which means it retrieves data without modifying state.
Register the IndexFoundry MCP server in PolicyLayer and add a rule for indexfoundry_serve_query: 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 IndexFoundry MCP. Nothing to install.
indexfoundry_serve_query 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 indexfoundry_serve_query 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 indexfoundry_serve_query. 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.
indexfoundry_serve_query is provided by the IndexFoundry MCP server (mnehmos/mnehmos.index-foundry.mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
