Postman MCP server for AI agents.
actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Postman and the rest of your systems. It gives your agent 245 Postman actions (110 reads, 104 writes and 31 that wait for a confirmation) and holds the Postman credential itself, so the agent never does. It paces Postman's limits and records every call.
100,000 free calls a month. No card, no email, no password: press Start a free sandbox on the next screen and keep the key it shows you.

Set up
Connect Postman in three steps.
- 01
Add actionlake to Claude.
Run the command once in Claude Code; its consent page can create a free sandbox: 100,000 calls a month, no card. In the Claude app, add a custom connector with the URL below and paste your key on the consent page. Creating a new sandbox from the Claude app is not yet tested by us.

Connect Postman.
API key. No consent screen: your agent can connect it for you, but the key then passes through your chat. To keep it out of the model's context, paste it in the console instead. actionlake stores what you paste write-only, sealed under your tenant's key.

Top actions
The Postman API, shaped for agents.
The ids your agent types, what each does, and the one name it shares with other systems. 151 of Postman's 157 action names are shared with at least one other connector, so an agent learns them once.

The plan store
Ready-made plans for Postman.
9 plans in the store. Install one and your agent runs it by name; the reply says which connections are still missing. A schedule can run a plan on a timetable. There are no triggers or webhooks, by design.
Triage unresolved secrets found by the secret scanner
Use it when Someone asks what leaked credentials Postman's secret scanner has flagged and where they appear.
Report catalogue service health for an environment
Use it when Someone wants a health snapshot of the services catalogued against a Postman system environment.
Read every open pull request on a collection
Use it when Someone wants a digest of the pull requests and forks outstanding on a Postman collection.
Audit a workspace's collections, environments and monitors
Use it when An agent needs a full read-only picture of what lives inside one Postman workspace.
Review and approve a collection pull request
Use it when A specific Postman pull request should be approved, but only after a human signs off.
A person decides
Approve pull request title against collection collection id.
Run a monitor and wait for the result
Use it when An agent needs to kick off a Postman monitor now and report on the outcome rather than fire and forget.
Work through pending team access requests
Use it when Pending Postman team join requests need clearing with human sign-off.
A person decides
Apply the decision decision to every pending access request on team team id.
Generate a collection from an API spec and tag it
Use it when An OpenAPI spec in Postman should be turned into a browsable collection and labelled.
Unpublish a mock server after checking its call logs
Use it when A mock server looks unused and someone wants it taken offline with a human sign-off first.
A person decides
Unpublish the mock server name, taking its public URL offline.

Destructive actions wait for a yes.
31 Postman actions are destructive. The first 10:
- Transfers a workspace from one team (`source`) to another team (`destination`)
postman.workspaces.transfer_to_team - Deletes an API specification
postman.specs.delete - Deletes an environment
postman.environments.delete - Deletes an existing workspace
postman.workspaces.delete - Deletes an SDK record and its stored archive
postman.sdks.delete - Deletes a collection
postman.collections.delete - Deletes an API
postman.apis.delete - Deletes an API version
postman.apis.delete_version - Deletes a mock server's server response
postman.mocks.delete_server_response - Deletes a collection access key
postman.collection_access_keys.delete
A destructive action runs only with confirm: true. Under the human policy the agent cannot confirm for itself: the run stops until a named person approves, in the console or from a signed link in an email. The cap on a key is refused before the call is sent, never after.
Deletes an API specification?

What Postman costs on actionlake.
Every Postman action is one upstream call, the only thing actionlake bills. Searching, check, cost, account and any call Postman refused with 401, 403, 429 or a 5xx are free. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000.

Questions
The Postman MCP server, answered.
Is there a Postman MCP server for Claude?
Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 245 Postman actions across collections, apis, specs and workspaces, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Postman.
What do I need to connect Postman?
Postman API key (PMAK-...), generated under Settings > API keys. Plus your host. The free call account { op: "connections.requirements", service: "postman" } lists exactly what to paste.
Can an AI agent delete or change things in Postman?
Only if its key allows it, and only with an explicit confirmation. 31 Postman actions are destructive, including transfers a workspace from one team (`source`) to another team (`destination`), deletes an API specification and deletes an environment. Each runs only with confirm: true. Under the human confirm policy, or an approval rule on the key, the run waits until a named person approves it.
Will an AI agent use up my Postman API limit?
actionlake paces every call to the limits in the Postman service file: 300 calls a minute per connection. Repeated reads are answered from cache (107 Postman actions can be), which never reaches Postman.
What does a Postman action cost?
One upstream call, the only unit actionlake bills. A list that pages bills one call per page (245 Postman actions page). Cache hits, searches, dry runs and calls Postman refused with 401, 403, 429 or a 5xx are free. The Free plan includes 100,000 calls a month with no card. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000.
Which Postman API does it cover?
The Postman API 2026-09 at api.getpostman.com by default, or the base URL set when you connect. It is built from Postman's documentation as read on 20 September 2026. 245 actions in 34 areas, each one in the signed service file (version 1.0.0).
Does actionlake keep my Postman data, and where?
actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to an hour, and a write clears the reads it affects. Each run's request and response is kept, sealed, for your plan's trace window: 1 day on Free, 3 days on Starter, 7 days on Pro, 14 days on Team, 30 days on Business and 30 days on Enterprise. Your Postman credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models.
Which AI clients can use it?
Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names.
