Can a collection be kept matching the OpenAPI spec?

Yes, in both directions. Sync Collection with Specification pushes spec changes into the collection, Generate Collection from Spec builds one from scratch, and Transform Collection to OpenAPI produces a spec from an existing collection, so the documented contract and the collection people run do not drift.

What decides which workspaces and collections are in reach?

The connected Postman account. Get Authenticated User identifies it, Get All Workspaces returns what it can see, and Get Workspace Roles and Get Collection Roles report the permissions on each, so the scope is readable before any action is enabled.

Could this expose credentials our team keeps in Postman?

It can read that layer, so it is worth checking. Get an Environment, Get Workspace Global Variables, and Get Collection Access Keys all return values held in Postman, so if secrets live in environments rather than in a vault, restrict those reads before the connection goes live.

Can Lyro take part in the review, not just push the change?

Create a Collection Comment and Create a Request Comment write into Postman's own review threads, Review a Pull Request records a verdict on a fork, and Resolve a Comment Thread closes one out, so feedback stays where the reviewers already are.

Postman MCP integration

Finds the collection or spec behind a question, stands up mock servers, runs monitors and reports the result, and routes changes through forks and pull requests.

146actions available

Three actions you can hand over today

Every action runs live through MCP. Nothing to build, nothing to maintain.

Get authenticated user
Lyro retrieves information about the currently authenticated Postman user. Integrations confirm user identity and permissions without manual lookup.
Generate collection from spec
Lyro converts an OpenAPI specification into a ready-to-use Postman collection. Teams start testing APIs instantly instead of manually building requests.
Run a monitor
Lyro triggers an immediate execution of a Postman API monitor and retrieves results. Developers test API health on-demand without waiting for scheduled monitor runs.

How businesses use Postman + Lyro

Each card is one request a support team gets, and the Postman actions Lyro runs to close it.

Find the endpoint someone is asking about
Lyro lists the collections in the workspace, opens the request inside the one that matches, and reads the specification behind it, so a question about how an endpoint behaves comes from the source.
Get All CollectionsGet Request InformationGet API Specification
Stand a mock up before the endpoint exists
Lyro creates the mock server on a collection, adds the example response it should return, and publishes it, so another team can build against the contract while the real service is still being written.
Create a Mock ServerCreate Mock Server ResponsePublish a Mock Server
Run the check and report what broke
Lyro runs the monitor against the collection, reads its result back, and lists the other monitors configured, so a question about whether an API is healthy is answered by actually testing it.
Run a MonitorGet Monitor InformationGet All Monitors
Propose a change without editing the shared collection
Lyro forks the collection, opens a pull request on the change, and pulls source changes back into the fork, so an update is reviewed rather than applied straight to what everyone runs.

How it works

Get started in 3 steps

Connect once, then just ask. There is no workflow builder to learn and nothing to maintain — Lyro reads the Postman actions it has and picks the ones a request needs.

01
Connect Postman
Authorize the Postman account your team already uses — one consent screen, no API keys, no mapping tables. Lyro can only do what you granted that account, and you can disconnect it at any time.
02
Tell your agent what you need
Describe the job the way you would hand it to a teammate. Lyro maps it to the Postman actions that close it and chains as many as the request needs.
03
Watch it work
The agent runs the actions inside the conversation the customer is already in, so nobody copies data between tabs and your team can take over at any point.

Everything else about Postman

Setup, permissions, and the limits of what Lyro can do inside Postman.

Yes, in both directions. Sync Collection with Specification pushes spec changes into the collection, Generate Collection from Spec builds one from scratch, and Transform Collection to OpenAPI produces a spec from an existing collection, so the documented contract and the collection people run do not drift.
