# list_collection_access_keys List collection access keys with optional filtering by collection ID Agent View of the PolicyLayer registry record for `list_collection_access_keys`. HTML page: https://policylayer.com/tools/delano-postman-mcp-server/list-collection-access-keys ## Facts - Tool: `list_collection_access_keys` - 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: Read (Low risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "list_collection_access_keys", "arguments": {} } } ``` ## Why list_collection_access_keys is rated Low This tool retrieves and exposes collection access keys, which are sensitive credentials that could grant unauthorized access to Postman collections if disclosed. While the operation itself is non-destructive and does not modify data, the high sensitivity of the data being read (access keys/credentials) warrants a 'high' severity rating due to potential for credential exposure and unauthorized access if misused by an… From the tool's own definition: "Tool name 'list_collection_access_keys' and description 'List collection access keys with optional filtering by collection ID' indicate a read/retrieval operation." ## Use case AI agents call list_collection_access_keys to retrieve information from Postman 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 Postman: ```json { "version": "1", "default": "deny", "tools": { "list_collection_access_keys": {} } } ``` ## 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.
