AI agents call search to retrieve information from PocketMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Semantic search queries an existing vector database and returns matching results without modifying, executing code, deleting data, or moving money. This is a pure retrieval operation with no side effects, fitting the 'Read' category. Severity is low because misuse simply returns unwanted search results rather than causing system compromise or data loss.
From the tool's definition Tool named 'search' with description 'Search for similar content using semantic search' performs only retrieval operations.
Attacks that exploit this kind of access
Search for similar content using semantic search. It is categorised as a Read tool in the PocketMCP MCP Server, which means it retrieves data without modifying state.
Register the Pocket MCP server in PolicyLayer and add a rule for 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 PocketMCP. Nothing to install.
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 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 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.
search is provided by the Pocket MCP server (kailash-sankar/pocketmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
