HTML page: https://policylayer.com/tools/kh0pper-crow/crow-add-source ## Facts - Tool: `crow_add_source` - Server: Crow (`kh0pper/crow`) — https://policylayer.com/tools/kh0pper-crow.md - Homepage: https://github.com/kh0pper/crow - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "crow_add_source", "arguments": {} } } ``` ## Why crow_add_source is rated Medium This tool creates new source records with metadata in the project management system. It is a Write operation because it creates/adds data reversibly without destructive or dangerous side effects. Severity is medium because misuse could pollute the project's source database with invalid, malicious, or irrelevant citations, but the impact is limited to data quality rather than data loss or system compromise. From the tool's own definition: "Tool description states it 'Add[s] a source' which is a data creation/modification operation. The mention of 'metadata' and 'automatic citation generation' indicates structured data is being created and stored." ## Use case AI agents use crow_add_source to create or update resources in Crow, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Crow environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
