AppSignal
What is AppSignal?
AppSignal is a user-friendly, all-in-one monitoring platform designed for developers. Get metrics, traces, logs, uptime monitoring, error tracking, AI insights, and more, with support for popular languages like Ruby, Elixir, Node.js, Python, PHP, Java, and Go.
Getting Started
Connect your MCP client to AppSignal. An AppSignal account is required. If you don't have one, sign up for free.
What you can access
AppSignal MCP exposes read and write access to your monitoring data across seven areas. Each area maps to a permission you can configure when authenticating: with an MCP token, set each area to read, write, or disabled; with OAuth, all read and write tools are exposed at once.
What you get back depends on what your apps send to AppSignal. If your app is not sending logs, get_log_lines will not return anything. AppSignal MCP is a gateway to data AppSignal already has. It does not collect new data on its own.
Available now
- Error incidents (read + write): list and search exceptions, inspect stack traces, update state and severity, assign handlers, and add notes
- Performance (read): rank slowest actions, pull traces, walk span trees, and inspect span attributes. Sample-based for standard Ruby and Elixir apps; OpenTelemetry traces for apps sending OTel data
- Anomaly detection (read + write): browse alerts, list existing triggers, and create, update, or archive triggers
- Logging (read + write): query log lines with AppSignal's expression syntax, and set up log ingestion rules: filter, trigger, and metrics actions. Particularly powerful for stitching together a customer journey across log sources, errors, and traces in one prompt — see reconstructing a customer journey
- Metrics (read): discover metric categories (including host_metrics), list metric names and tags, and pull timeseries or aggregated values
- Dashboards (read + write): create dashboards, and add or update chart visuals
- App discovery (read): list your applications, environments, namespaces, users, notifiers, log sources, log line actions, and deploy markers
