## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

    "name": "fw_search",

## Why fw_search is rated Low

This tool performs a read-only search operation against a catalog (local and cached federated data). It retrieves information without creating, modifying, deleting, or executing any operations. The default scope parameter suggests it queries existing data structures. Search operations have minimal blast radius and no side effects beyond data disclosure.

From the tool's own definition: "Tool name 'fw_search' and description 'Search the local + cached federated catalog' indicate a search/query operation with no modification or execution of code."

## Use case

AI agents call fw_search to retrieve information from Crow without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Crow:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "fw_search": {}
  }
}
```
