# fork_collection Fork a collection to a workspace Agent View of the PolicyLayer registry record for `fork_collection`. HTML page: https://policylayer.com/tools/delano-postman-mcp-server/fork-collection ## Facts - Tool: `fork_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": "fork_collection", "arguments": {} } } ``` ## Why fork_collection is rated Medium Forking a collection creates a new copy (derivative) of an existing collection in a workspace. This is a reversible write operation — it creates new data without modifying or deleting the original. The blast radius is medium since an AI agent could create many unwanted forks across workspaces, cluttering the environment, but no data is destroyed or financial impact incurred. From the tool's own definition: "Fork a collection to a workspace" ## Use case AI agents use fork_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**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Postman: ```json { "version": "1", "default": "deny", "tools": { "fork_collection": { "limits": [ { "counter": "fork_collection_rate", "window": "minute", "max": 30, "scope": "grant" } ] } } } ``` ## Other tools on Postman (97) - `delete_api` — Destructive — https://policylayer.com/tools/delano-postman-mcp-server/delete-api.md - `delete_api_comment` — Destructive — https://policylayer.com/tools/delano-postman-mcp-server/delete-api-comment.md - `delete_api_version` — Destructive — https://policylayer.com/tools/delano-postman-mcp-server/delete-api-version.md - `delete_collection` — Destructive — https://policylayer.com/tools/delano-postman-mcp-server/delete-collection.md - `delete_collection_access_key` — Destructive — https://policylayer.com/tools/delano-postman-mcp-server/delete-collection-access-key.md - `delete_collection_folder` — Destructive — https://policylayer.com/tools/delano-postman-mcp-server/delete-collection-folder.md - `delete_collection_request` — Destructive — https://policylayer.com/tools/delano-postman-mcp-server/delete-collection-request.md - `delete_collection_response` — Destructive — https://policylayer.com/tools/delano-postman-mcp-server/delete-collection-response.md - `delete_environment` — Destructive — https://policylayer.com/tools/delano-postman-mcp-server/delete-environment.md - `delete_mock` — Destructive — https://policylayer.com/tools/delano-postman-mcp-server/delete-mock.md - `delete_monitor` — Destructive — https://policylayer.com/tools/delano-postman-mcp-server/delete-monitor.md - `delete_schema_file` — Destructive — https://policylayer.com/tools/delano-postman-mcp-server/delete-schema-file.md - `delete_server_response` — Destructive — https://policylayer.com/tools/delano-postman-mcp-server/delete-server-response.md - `remove_pan_element` — Destructive — https://policylayer.com/tools/delano-postman-mcp-server/remove-pan-element.md - `create_webhook` — Execute — https://policylayer.com/tools/delano-postman-mcp-server/create-webhook.md - `get_accounts` — Read — https://policylayer.com/tools/delano-postman-mcp-server/get-accounts.md - `get_api` — Read — https://policylayer.com/tools/delano-postman-mcp-server/get-api.md - `get_api_collection` — Read — https://policylayer.com/tools/delano-postman-mcp-server/get-api-collection.md - `get_api_comments` — Read — https://policylayer.com/tools/delano-postman-mcp-server/get-api-comments.md - `get_api_schema` — Read — https://policylayer.com/tools/delano-postman-mcp-server/get-api-schema.md - `get_api_schema_files` — Read — https://policylayer.com/tools/delano-postman-mcp-server/get-api-schema-files.md - `get_api_tags` — Read — https://policylayer.com/tools/delano-postman-mcp-server/get-api-tags.md - `get_api_version` — Read — https://policylayer.com/tools/delano-postman-mcp-server/get-api-version.md - `get_api_versions` — Read — https://policylayer.com/tools/delano-postman-mcp-server/get-api-versions.md - `get_authenticated_user` — Read — https://policylayer.com/tools/delano-postman-mcp-server/get-authenticated-user.md - `get_collection` — Read — https://policylayer.com/tools/delano-postman-mcp-server/get-collection.md - `get_collection_folder` — Read — https://policylayer.com/tools/delano-postman-mcp-server/get-collection-folder.md - `get_collection_forks` — Read — https://policylayer.com/tools/delano-postman-mcp-server/get-collection-forks.md - `get_collection_request` — Read — https://policylayer.com/tools/delano-postman-mcp-server/get-collection-request.md - `get_collection_response` — Read — https://policylayer.com/tools/delano-postman-mcp-server/get-collection-response.md - …and 67 more: https://policylayer.com/tools/delano-postman-mcp-server.md ## For agents This record is a snapshot.
