# patch_collection Partially update a collection. Only updates provided fields. Agent View of the PolicyLayer registry record for `patch_collection`. HTML page: https://policylayer.com/tools/delano-postman-mcp-server/patch-collection ## Facts - Tool: `patch_collection` - Server: Postman (`delano/postman-mcp-server`) — https://policylayer.com/tools/delano-postman-mcp-server.md - Homepage: https://github.com/delano/postman-mcp-server - 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": "patch_collection", "arguments": {} } } ``` ## Why patch_collection is rated Medium The tool modifies collection data via a PATCH operation, which is a Write action (reversible update). It does not create new collections (that's handled by create_collection), does not delete (Destructive), and does not execute arbitrary code (Execute). The severity is medium because unintended collection modifications could disrupt Postman workflows, but the change can typically be reverted. From the tool's own definition: "Tool name 'patch_collection' and description 'Partially update a collection. Only updates provided fields.' indicate reversible modification of collection metadata or structure." ## Use case AI agents use patch_collection to create or update resources in Postman, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Postman environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
