Postman

createSpecFile

Creates an API specification file. **Note:** - If the file path contains a \`/\` (forward slash) character, then a folder is created. For example, if the path is the \`components/schemas.json\` value, then a \`components\` folder is created with the \`schemas.json\` file inside. - Creating a spec file assigns it the \`DEFAULT\` file type. - Multi-file specifications can only have one root file. - Files cannot exceed a maximum of 10 MB in size.

createWorkspace

Creates a new [workspace](https://learning.postman.com/docs/collaborating-in-postman/using-workspaces/creating-workspaces/). **Note:** - This endpoint returns a 403 \`Forbidden\` response if the user does not have permission to create workspaces. [Admins and Super Admins](https://learning.postman.com/docs/collaborating-in-postman/roles-and-permissions/#team-roles) can configure workspace permissions to restrict users and/or user groups from creating workspaces or require approvals for the creation of team workspaces. - Private and [Partner Workspaces](https://learning.postman.com/docs/collaborating-in-postman/using-workspaces/partner-workspaces/) are available on Postman [**Team** and **Enterprise** plans](https://www.postman.com/pricing). - There are rate limits when publishing public workspaces. - Public team workspace names must be unique. - The \`teamId\` property must be passed in the request body if [Postman Organizations](https://learning.postman.com/docs/administration/onboarding-checklist) is enabled.

duplicateCollection

Creates a duplicate of the given collection in another workspace. Use the GET \`/collection-duplicate-tasks/{taskId}\` endpoint to get the duplication task's current status.

generateCollection

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. The response contains a polling link to the task status.

generateSpecFromCollection

Generates an API specification for the given collection. The response contains a polling link to the task status.

getAllSpecs

Gets all API specifications in a workspace.

getAuthenticatedUser

Gets information about the authenticated user. - This endpoint provides “current user” context (\`user.id\`, \`username\`, \`teamId\`, roles). - When a user asks for “my …” (e.g., “my workspaces, my information, etc.”), call this first to resolve the user ID.

getCollection

Get information about a collection. By default this tool returns the lightweight collection map (metadata + recursive itemRefs). Use the model parameter to opt in to Postman's full API responses: - model=minimal — root-level folder/request IDs only - model=full — full Postman collection payload.

getCollections

The workspace ID query is required for this endpoint. If not provided, the LLM should ask the user to provide it.

getDuplicateCollectionTaskStatus

Gets the status of a collection duplication task.

getEnabledTools

IMPORTANT: Run this tool first when a requested tool is unavailable. Returns information about which tools are enabled in the full and minimal tool sets, helping you identify available alternatives.

getEnvironment

Gets information about an environment.

getEnvironments

Gets information about all of your [environments](https://learning.postman.com/docs/sending-requests/managing-environments/).

getGeneratedCollectionSpecs

Gets the API specification generated for the given collection.

getMock

Gets information about a mock server. - Resource: Mock server entity. Response includes the associated \`collection\` UID and \`mockUrl\`. - Use the \`collection\` UID to navigate back to the source collection.

getMocks

Gets all active mock servers. By default, returns only mock servers you created across all workspaces. - Always pass either the \`workspace\` or \`teamId\` query to scope results. Prefer \`workspace\` when known. - If you need team-scoped results, set \`teamId\` from the current user: call GET \`/me\` and use \`me.teamId\`. - If both \`teamId\` and \`workspace\` are passed, only \`workspace\` is used.

getSpec

Gets information about an API specification.

getSpecCollections

Gets all of an API specification's generated collections.

getSpecDefinition

Gets the complete contents of an API specification's definition.

getSpecFile

Gets the contents of an API specification's file.

getSpecFiles

Gets all the files in an API specification.

getTaggedEntities

**Requires an Enterprise plan.** Tagging is only available on Postman Enterprise plans. This tool returns a 404 error on Free, Basic, and Professional accounts. Gets Postman elements (entities) by a given tag. Tags enable you to organize and search workspaces, APIs, and collections that contain shared tags.

getWorkspace

Gets information about a workspace. **Note:** This endpoint's response contains the \`visibility\` field. [Visibility](https://learning.postman.com/docs/collaborating-in-postman/using-workspaces/managing-workspaces/#changing-workspace-visibility) determines who can access the workspace: - \`personal\` — Only you can access the workspace. - \`team\` — All team members can access the workspace. - \`private\` — Only invited team members can access the workspace ([**Team** and **Enterprise** plans only](https://www.postman.com/pricing)). - \`public\` — Everyone can access the workspace. - \`partner\` — Only invited team members and [partners](https://learning.postman.com/docs/collaborating-in-postman/using-workspaces/partner-workspaces/) can access the workspace ([**Team** and **Enterprise** plans only](https://www.postman.com/pricing)).

getWorkspaces

Gets all workspaces you have access to. - For “my …” requests, first call GET \`/me\` and pass \`createdBy={me.user.id}\`. - This endpoint's response contains the visibility field. Visibility determines who can access the workspace: - \`personal\` — Only you can access the workspace. - \`team\` — All team members can access the workspace. - \`private\` — Only invited team members can access the workspace (Professional and Enterprise). - \`public\` — Everyone can access the workspace. - \`partner\` — Invited team members and partners (Professional and Enterprise). - For tools that require the workspace ID, and no workspace ID is provided, ask the user to provide the workspace ID. If the user does not provide the workspace ID, call this first with the createdBy parameter to use the first workspace. - Examples: - “List my workspaces” → GET \`/me\`, then GET \`/workspaces?createdBy={me.user.id}\` - “List my personal workspaces” → GET \`/me\`, then GET \`/workspaces?type=personal&createdBy={me.user.id}\` - “List all public workspaces” → GET \`/workspaces?type=public\`

publishMock

Publishes a mock server. Publishing a mock server sets its **Access Control** configuration setting to public.

putCollection

Replaces the contents of a collection using the [Postman Collection v2.1.0 schema format](https://schema.postman.com/collection/json/v2.1.0/draft-07/docs/index.html). Include the collection's ID values in the request body. If you do not, the endpoint removes the existing items and creates new items. - To perform an update asynchronously, use the \`Prefer\` header with the \`respond-async\` value. When performing an async update, this endpoint returns a HTTP \`202 Accepted\` response. - For a complete list of properties and information, see the [Postman Collection Format documentation](https://schema.postman.com/collection/json/v2.1.0/draft-07/docs/index.html). - For protocol profile behavior, refer to Postman's [Protocol Profile Behavior documentation](https://github.com/postmanlabs/postman-runtime/blob/develop/docs/protocol-profile-behavior.md). **Note:** - The maximum collection size this endpoint accepts cannot exceed 100 MB. - Use the GET \`/collection-updates-tasks/{taskId}\` endpoint to get the collection's update status when performing an asynchronous update. - If you don't include the collection items' ID values from the request body, the endpoint **removes** the existing items and recreates the items with new ID values. - To copy another collection's contents to the given collection, remove all ID values before you pass it in this endpoint. If you do not, this endpoint returns an error. These values include the \`id\`, \`uid\`, and \`postman_id\` values.

putEnvironment

Replaces all the contents of an environment with the given information. **Note:** - The request body size cannot exceed the maximum allowed size of 30MB. - If you receive an HTTP \`411 Length Required\` error response, manually pass the \`Content-Length\` header and its value in the request header.
