Search for content using hybrid semantic and exact term matching. Combines vector similarity search with exact term boosting for precise results. At least one of semantic_concepts or exact_terms must be provided.
AI agents call search_content to retrieve information from Folder without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
search_content retrieves matching files or document excerpts based on search criteria. It does not create, modify, delete, or execute anything—it only returns results. The hybrid search mechanism (semantic + exact matching) is a sophisticated retrieval method, not a state-changing operation.
From the tool's definition Tool performs 'search for content using hybrid semantic and exact term matching' with 'vector similarity search' — operations that query and retrieve data without modifying it.
Documented attack patterns abuse exactly the kind of access search_content gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Folder, and nothing reaches the server without passing your rules. This is the rule we recommend for search_content:
{
"version": "1",
"default": "deny",
"tools": {
"search_content": {}
}
}search_content is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search for content using hybrid semantic and exact term matching. Combines vector similarity search with exact term boosting for precise results. At least one of semantic_concepts or exact_terms must be provided. It is categorised as a Read tool in the Folder MCP Server, which means it retrieves data without modifying state.
Register the Folder MCP server in PolicyLayer and add a rule for search_content: 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 Folder. Nothing to install.
search_content 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_content 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_content. 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_content is provided by the Folder MCP server (okets/folder-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Folder, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
