About
AppSignal MCP Server
This is the official AppSignal [MCP][mcp] server. Everything necessary to debug using AppSignal's monitoring data, metrics, and tools is now accessible from your favorite AI editor.
This feature is in Beta. Documentation can also be found here
Join our [Discord community][discord] to help shape this MCP implementation. Feature requests are welcome!
Prerequisites
- Docker
- An [AppSignal account][appsignal-sign-up] and an [AppSignal MCP token][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:
- Start the TypeScript compiler in watch mode:
``bash npm run watch ``
- Run tests:
``bash npm test ``
- Use the MCP inspector for debugging:
``bash 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
