# Postman MCP tool for ADK

Supported in ADKPythonTypeScriptGo

The [Postman MCP Server](https://github.com/postmanlabs/postman-mcp-server) connects your ADK agent to the [Postman](https://www.postman.com/) ecosystem. This integration gives your agent the ability to access workspaces, manage collections and environments, evaluate APIs, and automate workflows through natural language interactions.

## Use cases

- **API testing**: Continuously test your APIs using your Postman collections.
- **Collection management**: Create and tag collections, update documentation, add comments, or perform actions across multiple collections without leaving your editor.
- **Workspace and environment management**: Create workspaces and environments, and manage your environment variables.
- **Client code generation**: Generate production-ready client code that consumes APIs following best practices and project conventions.

## Prerequisites

- Create a [Postman account](https://identity.getpostman.com/signup)
- Generate a [Postman API key](https://postman.postman.co/settings/me/api-keys)

## Use with agent

```python

POSTMAN_API_KEY = "YOUR_POSTMAN_API_KEY"

root_agent = Agent(
    model="gemini-flash-latest",

## Configuration

Postman offers three tool configurations:

- **Minimal** (default): Essential tools for basic Postman operations. Best for simple modifications to collections, workspaces, or environments.
- **Full**: All available Postman API tools (100+ tools). Ideal for advanced collaboration and enterprise features.
- **Code**: Tools for searching API definitions and generating client code. Perfect for developers who need to consume APIs.

To select a configuration:

- **Local server**: Add `--full` or `--code` to the `args` list.
- **Remote server**: Change the URL path to `/minimal`, `/mcp` (full), or `/code`.

For EU region, use `--region eu` (local) or `https://mcp.eu.postman.com` (remote).
