Setup
Install AppSignal MCP in your MCP client (Claude Desktop, Cursor, Windsurf, and others).
Repository: https://github.com/pauldub/appsignal-mcp
Follow the installation instructions in the repository README, then restart your MCP client.
A Model Context Protocol (MCP) server for AppSignal monitoring API integration. This server allows AI assistants to directly query and fetch error and performance data from AppSignal through the MCP protocol.
- Fetch details about specific error or performance samples
- Search for errors, performance samples, or both with flexible filters
- Integration with AppSignal's Error and Performance Monitoring APIs
- Bunruntime
- AppSignal account and API token
- Application ID from your AppSignal dashboard
# Clone the repository git clone https://github.com/pauldub/appsignal-mcp.git cd appsignal-mcp # Install dependencies bun install
Create a.envfile in the root directory with your AppSignal credentials:
# Server configuration PORT=3000 LOG_LEVEL=info # AppSignal configuration APPSIGNAL_API_TOKEN=your-api-token
# Run the server bun start # Development mode with auto-reload bun dev # Run tests bun test # Build a standalone executable bun run build
appsignal-mcp --appsignal-api-token your-token
- --appsignal-api-token <token>- AppSignal API token
- --log-level <level>- Logging level (debug, info, warn, error)
- --port <port>- Server port number
Gets details about a specific sample by ID (error or performance).
- sampleId(string, required): The AppSignal sample ID
- appId(string, required): The AppSignal application ID
Searches for samples in an application with optional filters.
- appId(string, required): The AppSignal application ID
- sample_type(string, optional): Type of samples to search - "all", "errors", or "performance" (defaults to "errors")
- exception(string, optional): Filter by exception name (e.g., "NoMethodError") - only applicable for error samples
- action_id(string, optional): Filter by action name (e.g., "BlogPostsController-hash-show")
- since(string/number, optional): Start timestamp in UTC (timestamp or ISO format)
- before(string/number, optional): End timestamp in UTC (timestamp or ISO format)
- limit(number, optional): Maximum number of samples to return (defaults to 10)
- count_only(boolean, optional): Only return the count, not the samples
To use this MCP server with Claude, create a.mcp.jsonfile in your Claude Code workspace:
{ "mcpServers": { "appsignal-mcp": { "type": "stdio", "command": "bun", "args": [ "run", "start" ], "env": { "APPSIGNAL_API_TOKEN": "your-api-token" } } } }
