AI-driven semantic search for academic literature. Input natural language query to find relevant papers.
AI agents call search_documents to retrieve information from Suppr MCP 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 academic literature data without creating, modifying, deleting, or executing external operations. It is a pure read operation over PubMed documents with no capability to alter data or trigger side effects beyond returning search results.
From the tool's definition Tool description states it performs 'AI-driven semantic search' to 'find relevant papers' — a query operation with no side effects. Named search_documents and explicitly inputs 'natural language query', consistent with retrieval-only functionality.
Documented attack patterns abuse exactly the kind of access search_documents gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Suppr MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for search_documents:
{
"version": "1",
"default": "deny",
"tools": {
"search_documents": {}
}
}search_documents is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

AI-driven semantic search for academic literature. Input natural language query to find relevant papers. It is categorised as a Read tool in the Suppr MCP MCP Server, which means it retrieves data without modifying state.
Register the Suppr 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 Suppr MCP. 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 Suppr MCP server (wilddatax/suppr-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
