## What it does

This MCP server connects Claude Code with the AppSignal REST API. The available tools list applications, select an application ID, inspect exception, log, and anomaly incidents, and search application logs with query parameters. Incident lists can be filtered by `OPEN`, `CLOSED`, or `WIP`; an unfiltered list uses `OPEN`.

The server runs through `npx` and requires `APPSIGNAL_API_KEY`. You can also set `APPSIGNAL_APP_ID` to select an application in advance. Node.js `v24.2.0` is required. Without an AppSignal API key, the server cannot connect.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `APPSIGNAL_API_KEY`, `APPSIGNAL_APP_ID` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## When to use it
- search application logs with filters
- inspect an exception or anomaly incident
- list incidents that are still open
- connect an incident to related log entries
- select an AppSignal application for analysis

## Example prompts
- Show the open AppSignal incidents and group them by type.
- Select the AppSignal application, then search its logs for errors in the requested time range.
- Inspect this exception incident and look for related entries in the application logs.
