# create_api_version Create a new version of an API Agent View of the PolicyLayer registry record for `create_api_version`. HTML page: https://policylayer.com/tools/delano-postman-mcp-server/create-api-version ## Facts - Tool: `create_api_version` - 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_version", "arguments": {} } } ``` ## Why create_api_version is rated Medium This tool creates a new API version within Postman, which is a reversible write operation with no destructive effects. It modifies the API metadata by adding a version record but does not execute external operations, delete data, or trigger financial transactions. Low severity because misuse typically results in clutter rather than severe damage. From the tool's own definition: "Tool name 'create_api_version' and description 'Create a new version of an API' indicate data creation; sibling tools like 'create_api', 'create_collection', and 'create_environment' are clearly Write operations; versioning is a reversible operation in…" ## Use case AI agents use create_api_version 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_version": { "limits": [ { "counter": "create_api_version_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.
