Postman
Access workspaces, manage collections and environments, and generate client code. With Lunar.dev MCPX, the MCP Gateway for secure and governed tool access, you connect the Postman MCP server to Claude, ChatGPT, Cursor, and any MCP client through one gateway that routes, authenticates, and governs every Postman tool call against your policies.
Why MCPX
MCPX is Lunar.dev's MCP Gateway. It sits between your AI agents and your MCP servers as a single gateway for every tool call, routing, authenticating, and governing traffic against your policies. Connect Postman once and govern it everywhere: role-based access per agent with on-behalf-of attribution, real-time visibility, and an immutable audit trail of who did what, all deployable inside your own VPC.
Tools content
- createCollection · Write
Creates a collection using the Postman Collection v2.1.0 schema format; if the workspace query parameter is omitted, the collection is created in the oldest personal Internal workspace you own. - createEnvironment · Write
Creates an environment. - createMock · Write
Creates a mock server in a collection. - createSpec · Write
Creates an API specification in Postman's Spec Hub; specifications can be single or multi-file. - createSpecFile · Write
Creates a file for an OpenAPI or a protobuf 2 or 3 specification. - createWorkspace · Write
Creates a new workspace. - generateCollection · Write
Creates a collection from the given API specification; the specification must already exist or be created before it can be used to generate a collection, and the response contains a polling link to the task status. - generateSpecFromCollection · Write
Generates an OpenAPI 2.0, 3.0, or 3.1 specification for the given collection; the response contains a polling link to the task status. - getAllSpecs · Read-only
Gets all API specifications in a workspace. - getAuthenticatedUser · Read-only
Gets information about the authenticated user. - getCollection · Read-only
Get information about a collection; by default this tool returns the lightweight collection map (metadata + recursive itemRefs). - getCollections · Read-only
The workspace ID query is required for this endpoint; if not provided, the LLM should ask the user to provide it. - getEnvironment · Read-only
Gets information about an environment. - getEnvironments · Read-only
Gets information about all of your environments. - getGeneratedCollectionSpecs · Read-only
Gets the API specification generated for the given collection. - getMock · Read-only
Gets information about a mock server. - getMocks · Read-only
Gets all active mock servers; by default, returns only mock servers you created across all workspaces. - getSpec · Read-only
Gets information about an API specification. - getSpecCollections · Read-only
Gets all of an API specification's generated collections. - getSpecDefinition · Read-only
Gets the complete contents of an OpenAPI or AsyncAPI specification's definition.
Frequently asked questions
What is the Postman MCP server?
Access workspaces, manage collections and environments, and generate client code. Through Lunar.dev MCPX, Postman connects to any MCP-compatible AI client behind a single governed gateway.
How do I connect Postman to MCPX?
Add the Postman server in the MCPX control plane or your app.yaml, then point your AI client at your MCPX gateway. MCPX handles OAuth and routes every Postman call through the gateway.
Is the Postman MCP server official?
Yes. Postman is an official, vendor-published MCP server, and MCPX governs it like any other server in your catalog.
What authentication does Postman use with MCPX?
Postman uses OAuth. MCPX enforces authentication at the gateway with token-based auth, OAuth, and role-based profiles, so you control which agents can invoke it.
How many tools does Postman expose in MCPX?
Postman exposes 100+ tools. In MCPX you can enable or disable each tool per agent for least-privilege access.
