Search through documents with a query
AI agents call search-documents to retrieve information from IMCP - Insecure Model Context Protocol without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries documents based on user input with no stated side effects. However, severity is elevated to 'medium' rather than 'low' because: (1) the parent server (IMCP) is explicitly described as 'deliberately vulnerable' with '16 critical security weaknesses', suggesting this tool may lack proper access controls or input validation; (2) document search on an insecure system could expose sensitive…
From the tool's definition Tool name 'search-documents' and description 'Search through documents with a query' indicate data retrieval without modification. The 'search' verb and 'query' parameter confirm this is a Read operation.
Attacks that exploit this kind of access
Search through documents with a query. It is categorised as a Read tool in the IMCP - Insecure Model Context Protocol MCP Server, which means it retrieves data without modifying state.
Register the IMCP - Insecure Model Context Protocol MCP server in PolicyLayer and add a rule for search-documents: 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 IMCP - Insecure Model Context Protocol. Nothing to install.
search-documents 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-documents 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-documents. 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-documents is provided by the IMCP - Insecure Model Context Protocol MCP server (nav33n25/imcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
