# create_api Create a new API Agent View of the PolicyLayer registry record for `create_api`. HTML page: https://policylayer.com/tools/delano-postman-mcp-server/create-api ## Facts - Tool: `create_api` - 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": "create_api", "arguments": {} } } ``` ## Why create_api is rated Medium Creating an API in Postman is a reversible operation that adds new data to the user's workspace. While it modifies the system state, it does not execute external code, delete data, or trigger financial transactions. This is Write-category behavior with medium severity: an AI misusing this could spam API definitions or pollute a workspace, but the impact is bounded and reversible. From the tool's own definition: "Tool name 'create_api' and description 'Create a new API' indicate the tool creates new resources in Postman." ## Use case AI agents use create_api 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": { "create_api": { "limits": [ { "counter": "create_api_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.
