semantic_search
AI agents call semantic_search to retrieve information from Pinecone Economic Books without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The semantic_search tool queries a vector database to retrieve relevant documents matching natural language queries. This is a retrieval operation with no ability to modify, delete, or execute external code. Despite the empty description for this specific tool, the server context and sibling tools (all search/retrieval operations) confirm this is a Read category tool.
From the tool's definition Tool name 'semantic_search' combined with server description indicating the tool 'Enables semantic search through a Pinecone vector database containing economic books and academic papers using natural language queries.' This is a read-only query operation…
Attacks that exploit this kind of access
semantic_search. It is categorised as a Read tool in the Pinecone Economic Books MCP Server, which means it retrieves data without modifying state.
Register the Pinecone Economic Books MCP server in PolicyLayer and add a rule for semantic_search: 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 Pinecone Economic Books. Nothing to install.
semantic_search 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 semantic_search 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 semantic_search. 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.
semantic_search is provided by the Pinecone Economic Books MCP server (srulyrosenblat/econ_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
