Prerequisites

• Docker
• An AppSignal account and an AppSignal MCP token.

Installation

Pull the Docker image:

docker pull appsignal/mcp:latest

Configuration

Claude

Configure Claude to use the AppSignal MCP server by editing the ~/Library/Application Support/Claude/claude_desktop_config.json file:

{
  "mcpServers": {
    "appsignal": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "-e", "APPSIGNAL_API_KEY", "appsignal/mcp"],
      "env": {
        "APPSIGNAL_API_KEY": "your_api_key_here"
      }
    }
  }
}

You can find this by navigating to your Profile -> Settings -> Developer and then clicking Edit Config

Claude Code

To enable AppSignal MCP in Claude Code, run the following command:

claude mcp add appsignal -e APPSIGNAL_API_KEY=your_api_key_here -- docker run -i --rm -e APPSIGNAL_API_KEY appsignal/mcp

Cursor and Windsurf

To enable AppSignal MCP in Cursor or Windsurf, edit your configuration file.

For Cursor use ~/.cursor/mcp.json

For Windsurf use ~/.codeium/windsurf/mcp_config.json

Add the following configuration:

{
  "mcpServers": {
    "appsignal": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "-e", "APPSIGNAL_API_KEY", "appsignal/mcp"],
      "env": {
        "APPSIGNAL_API_KEY": "your-mcp-token"
      }
    }
  }
}

Zed

Open your Zed settings file and add the context_servers section:

{
  "context_servers": {
    "appsignal": {
      "source": "custom",
      "command": "docker",
      "args": ["run", "-i", "--rm", "-e", "APPSIGNAL_API_KEY", "appsignal/mcp"],
      "env": {
        "APPSIGNAL_API_KEY": "your-mcp-token"
      }
    }
}

VSCode

If you are running GitHub Copilot, and are signed in under a company account, make sure to set "MCP servers in Copilot" to "Enabled" under your organization settings > Copilot > Policies.

Then add this config to your .vscode/mcp.json settings:

{
  "inputs": [
    {
      "type": "promptString",
      "id": "appsignal_mcp_token",
      "description": "AppSignal MCP Token",
      "password": true
    }
  ],
  "servers": {
    "appsignal": {
      "command":  "docker"
      "args": [
        "run",
        "-i",
        "--rm",
        "-e",
        "APPSIGNAL_API_KEY",
        "appsignal/mcp"
      ],
      "env": {
        "APPSIGNAL_API_KEY": "${input:appsignal_mcp_token}"
      }
    }
  }
}

Development

To work on the MCP server:

1. Start the TypeScript compiler in watch mode:

npm run watch

2. Run tests:

npm test

3. Use the MCP inspector for debugging:

npm run inspector

Change management

Every change that will results in a new version to be released, requires a changeset.

Changesets are small Markdown file that describe the change for the end-user.

The changeset's frontmatter describes the type of change (new feature, bug fix, etc.) and the version bump (major, minor, or patch).

Use Mono's changeset CLI to generate a new changeset file.

Commit the changeset file and include it in your Pull Requests.

mono changeset add

Publishing

Install Mono, the tool used for release management.

git pull # Ensure you have the latest version

mono publish # Publish a new version
