Postman MCP Server

This project offers the following Model Context Protocol (MCP) server options:

• STDIO
• Streamable HTTP

For more information about the available transports, see the MCP specification.

STDIO

This is a lightweight solution that's ideal for integration with editors and tools like VS Code.

For Docker set up and installation, see DOCKER.md.

VS Code integration

Note: VS Code only supports up to 128 tools. By default, this server provides 37 tools (minimal mode). Use the --full flag to access all 106 tools, but note this may exceed VS Code's 128 tool limit when combined with other MCP servers.

Integrate your MCP server with Visual Studio Code and use it with VS Code extensions that support MCP. To do this, do the following:

1. Create a .vscode/mcp.json file in your project and enter the following:

   {
       "servers": {
           "postman-api-mcp": {
               "type": "stdio",
               "command": "node",
               "args": [
                   "${workspaceFolder}/dist/src/index.js",
                   "--full" // (optional) Use this flag to enable full mode
               ],
               "env": {
                   "POSTMAN_API_KEY": "${input:postman-api-key}"
               }
           }
       },
       "inputs": [
           {
               "id": "postman-api-key",
               "type": "promptString",
               "description": "Enter your Postman API key"
           }
       ]
   }
   

2. Install an MCP-compatible VS Code extension, such as GitHub Copilot, Claude for VS Code, or other AI assistants that support MCP.

Configure the extension

Configure the extension to use the postman-api-mcp server, a local STDIO-based server that runs directly from your project files:

1. Clone the postman-mcp-server repository.
2. In the repository's root folder, run the npm install command. This installs all the required dependencies.
3. Replace ${workspaceFolder} in the mcp.json file with the full path to the Postman MCP repository.
4. When prompted, enter your Postman API key.

Claude integration

To integrate the MCP server with Claude, check the latest Postman MCP server release and get the .dxt file. For more information, see Anthropic's Claude Desktop Extensions documentation.

Streamable HTTP

The streamable HTTP version is available at https://mcp.postman.com. It supports two tool configurations to better serve different use cases:

• Minimal — Only includes essential tools for basic Postman operations, available at https://mcp.postman.com/minimal. This offers faster performance and simplifies use for those who only need basic Postman operations.
• Full — Includes all available Postman API tools (100+ tools), available at https://mcp.postman.com/mcp.

Cursor integration

To integrate the MCP server with Cursor, click the following button:

VS Code integration

VS Code only supports up to 128 tools. By default, the server provides 37 tools. Use Full (https://mcp.postman.com//mcp) mode to access all 106 tools, but note this may exceed VS Code's 128 tool limit when combined with other MCP servers.

To install in VS Code, add the following to the .vscode/mcp.json file:

{
    "servers": {
        "postman-api-http-server": {
            "type": "sse",
            "url": "https://mcp.postman.com/{minimal | mcp}", // choose "minimal" or "mcp"
            "headers": {
                "Authorization": "Bearer ${input:postman-api-key}"
            }
        }
    },
    "inputs": [
        {
            "id": "postman-api-key",
            "type": "promptString",
            "description": "Enter your Postman API key"
        }
    ]
}

When prompted, enter your Postman API key. Afterwards, the agent performs calls to the Postman cloud MCP server at https://mcp.postman.com.

Migration from v1.x to v2.x

• Tool naming changes - All tool names changed from kebab-case to camelCase. For example:
  • create-collection → createCollection
  • get-workspaces → getWorkspaces
  • delete-environment → deleteEnvironment
• Tool availability changes
  • The default (Minimal) behavior provides only 37 essential tools.
  • Minimal mode is designed to stay within VS Code's 128 tool limit when combined with other MCP servers.
  • The --full flag provides access to all 106 tools.
