Set up a local Postman MCP server

The local server is based on STDIO transport and is hosted locally on an environment of your choice. STDIO is a lightweight solution that’s ideal for integration with editors and tools like Visual Studio Code. Install an MCP-compatible VS Code extension, such as GitHub Copilot, Claude for VS Code, or other AI assistants that support MCP. The local server only supports API key authentication (with a Postman API key or Bearer token).

Before you begin

Local servers only support API key authentication, so you’ll need to generate a Postman API key. For an overview of the server, remote versus local, and when to use each configuration, see Use AI agents with the Postman API.

Supported configurations

The local server supports the same tool configurations as the remote server—Minimal (default), Code, and Full—selected with a command-line flag.

Use the --region flag to specify the Postman API region (us or eu), or set the POSTMAN_API_BASE_URL environment variable directly. By default, the server uses the us option.

Claude Code

To install the MCP server in Claude Code, run one of the following commands in your terminal:

$
claude mcp add postman --env POSTMAN_API_KEY=<POSTMAN_API_KEY> -- npx @postman/postman-mcp-server@latest

Cursor

Click the button to install the local Postman MCP server in Cursor:

Manual installation

To manually integrate your MCP server with Cursor and VS Code, create a .vscode/mcp.json file in your project and add one of the following JSON blocks to it. You can optionally include the --region flag to specify the Postman API region (us or eu). Defaults to us (in the args array, specify it as "--region", "eu").

To create a manual configuration, create a mcp.json file in your project and add one of the following JSON blocks to it:

1
{
2
    "servers": {
3
        "postman": {
4
            "type": "stdio",

Claude

To integrate the local Postman MCP server with Claude, check the latest Postman MCP server release and get the .mcpb file:

• Minimal — postman-api-mcp-minimal.mcpb
• Code — postman-mcp-server-code.mcpb
• Full — postman-api-mcp-full.mcpb

For more information, see the Claude Desktop Extensions documentation.
