Generate an OpenAPI 3.1 specification for the index API. Configurable endpoints: search_semantic, search_hybrid, get_chunk, health, stats.
AI agents call indexfoundry_serve_openapi 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 reads or queries the configuration of an index API and outputs a specification document. It has no side effects—it does not create, modify, delete, or execute operations against the underlying data or infrastructure. The specification itself is informational metadata used for documentation or client code generation.
From the tool's definition Tool generates (produces) an OpenAPI 3.1 specification document for the index API with configurable endpoints.
Attacks that exploit this kind of access
Generate an OpenAPI 3.1 specification for the index API. Configurable endpoints: search_semantic, search_hybrid, get_chunk, health, stats. 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_openapi: 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_openapi 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_openapi 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_openapi. 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_openapi 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.
