AI agents call smart_search_api to retrieve information from Apifox Filter MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a search and retrieval tool that queries and filters API documentation endpoints. It returns information based on user input but does not create, modify, delete, or execute any side effects. It operates purely as a Read operation with minimal risk—an AI agent misusing this tool would only retrieve incorrect or excessive API documentation, which is low severity in isolation.
From the tool's definition Tool description indicates it performs intelligent search of API endpoints based on natural language descriptions, automatically extracting keywords and returning sorted results.
Documented attack patterns abuse exactly the kind of access smart_search_api gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Apifox Filter MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for smart_search_api:
{
"version": "1",
"default": "deny",
"tools": {
"smart_search_api": {}
}
}smart_search_api is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Apifox Filter MCP Server MCP server in PolicyLayer and add a rule for smart_search_api: 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 Apifox Filter MCP Server. Nothing to install.
smart_search_api 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 smart_search_api 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 smart_search_api. 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.
smart_search_api is provided by the Apifox Filter MCP Server MCP server (xiaou66/apifox-filter-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Apifox Filter MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
