Setting up with Highlight

This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:

Download and install Highlight from highlightai.com/download
Navigate to the plugins tab and select "Add Custom Plugin"
Configure the plugin with the settings below
Plugin Name Bruno API

Command (node, npx, python, etc.) node
Arguments
- Argument 1 --loader
- Argument 2 ts-node/esm
- Argument 3 src/index.ts
- Argument 4 --bruno-path
- Argument 5 /path/to/bruno/collection
Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
Enable "Start Automatically" if you want the plugin to start when Highlight launches

Setting up with Cursor

Open Cursor's settings
Navigate to the MCP section
Click "Add new Global MCP server"

From the repository

1. Install dependencies:

   npm install

2. Start the server with your Bruno API collection:

   node --loader ts-node/esm src/index.ts --bruno-path /path/to/bruno/collection [--environment env_name] [--include-tools tool1,tool2,tool3] [--exclude-tools tool4,tool5]

Options:

- --bruno-path or -b: Path to your Bruno API collection directory (required)
- --environment or -e: Name of the environment to use (optional)
- --include-tools: Comma-separated list of tool names to include, filtering out all others (optional)
- --exclude-tools: Comma-separated list of tool names to exclude (optional)

Both formats are supported for the tool filtering options:

   --include-tools tool1,tool2,tool3    # Space-separated format
   --include-tools=tool1,tool2,tool3    # Equals-sign format

3. Connect from clients:
- Local connection: http://localhost:8000/sse
- From Windows to WSL: http://<WSL_IP>:8000/sse
- Get your WSL IP with: hostname -I | awk '{print $1}'

npm run start:local

Run all tests:

npm test

Run specific test file:

npm test test/bruno-parser-auth.test.ts

Lists all available environments in your Bruno API collection:

- No parameters required
- Returns:
- List of available environments
- Currently active environment

You can specify a different environment for a specific request:

{
  "environment": "us-dev"
}

This will use the variables from the specified environment instead of the default one.

`List Environments`

Lists all available environments in your Bruno API collection. No parameters required. Returns a list of available environments and the currently active environment.

`Echo`

Echoes back a message you send, useful for testing. Parameter: message (string).

Bruno API MCP Server

A Model Context Protocol (MCP) server that exposes Bruno API collections as MCP tools. This server allows you to interact with your Bruno API collections through the MCP protocol, making your API collections accessible to AI agents and other MCP clients.

Why This Matters: Source Code and Data Working Together

When developers need to integrate APIs, they typically face three core challenges:

1. Debugging across system boundaries: Diagnosing issues across separate code and data environments requires constant context switching, making troubleshooting inefficient.

2. Creating custom tooling: Each third-party API integration requires building and maintaining custom tooling, causing development overhead and technical debt.

3. Building service UIs: Developing user interfaces for every backend service adds significant complexity and maintenance costs.

This server solves these precise problems by collocating your source code with your data. It transforms Bruno API collections into Model Context Protocol tools, enabling you to:

- Debug across previously separate environments with complete context
- Turn any API into an agent-ready tool without additional custom development
- Build headless services that can be controlled through AI interfaces

For development teams that need to accelerate API integration while reducing maintenance overhead, this approach fundamentally changes what's possible - making previously complex integrations straightforward and accessible.

Features

Usage

1. Install dependencies:

   npm install

2. Start the server with your Bruno API collection:

   node --loader ts-node/esm src/index.ts --bruno-path /path/to/bruno/collection [--environment env_name] [--include-tools tool1,tool2,tool3] [--exclude-tools tool4,tool5]

Options:

Both formats are supported for the tool filtering options:

   --include-tools tool1,tool2,tool3    # Space-separated format
   --include-tools=tool1,tool2,tool3    # Equals-sign format

3. Connect from clients:
- Local connection: http://localhost:8000/sse
