search_files
Recursively search for files and directories
Part of the Filesystem MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
WHEN AI AGENTS USE THIS TOOL
AI agents call search_files to retrieve information from Filesystem without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions — but you may still want rate limits to control API costs.
WHY ENFORCE A POLICY ON SEARCH_FILES
Even though search_files only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
RECOMMENDED POLICY
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

FREQUENTLY ASKED QUESTIONS
What does the search_files tool do?
Recursively search for files and directories. It is categorised as a Read tool in the Filesystem MCP Server, which means it retrieves data without modifying state.
How do I enforce a policy on search_files?
Add a rule in your Intercept YAML policy under the tools section for search_files. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Filesystem MCP server.
What risk level is search_files?
search_files is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Can I rate-limit search_files?
Yes. Add a rate_limit block to the search_files rule in your Intercept 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.
How do I block search_files completely?
Set action: deny in the Intercept policy for search_files. 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.
What MCP server provides search_files?
search_files is provided by the Filesystem MCP server (modelcontextprotocol/server-filesystem). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
