AppSignal MCP is an MCP server that retrieves alert details and searches AppSignal logs within time ranges from your agent.
About
AppSignal MCP (com.pulsemcp/appsignal) connects your coding agent to an AppSignal account so you can inspect alerts and logs during firefighting. developers who already instrument Rails, Node, or other supported stacks with AppSignal can run the stdio server through npx with a required API key and optionally pin an application ID. Instead of context-switching to the web UI for every spike, the agent can search logs and pull time-windowed entries while you patch. It does not replace dashboards, paging policies, or root-cause analysis discipline. Skip it if you do not use AppSignal or you are pre-launch with no production telemetry. This is an operational MCP integration, not a testing or security scanner.
- Fetch alert details from AppSignal via MCP tools
- Search logs and retrieve logs within configurable time ranges
- stdio npm server appsignal-mcp-server (npx -y), version 0.5.3
- Requires APPSIGNAL_API_KEY; optional APPSIGNAL_APP_ID with dynamic app selection
- Published from pulsemcp/mcp-servers experimental/appsignal subfolder

What it does
Query AppSignal alerts and logs from your agent when debugging production issues without leaving the IDE.
Who is it for?
Best when you're already on AppSignal and want Claude Code or Cursor to help triage alerts and log searches.
Skip if: Skip if you're without AppSignal, greenfield projects with no production app, or shops that forbid production API keys in local agents.
What you get
Your agent can query AppSignal alerts and logs in-thread so you fix incidents faster with less context switching.
- Alert detail snapshots accessible to the agent
- Log search and time-range log retrieval for debugging sessions
By the numbers
- Server version 0.5.3
- APPSIGNAL_API_KEY required; APPSIGNAL_APP_ID optional

PulseMCP's MCP Servers
We build reliable servers thoughtfully designed for MCP Client-powered workflows.
Design principles
You can have confidence that any Pulse-branded MCP server was built with these north stars in mind:
- Purpose-built. LLM-powered MCP clients offer uniquely new user interaction patterns that necessitate a different layer of abstraction than the REST API's from a pre-AI era. We thoughtfully scope drawing lines like building a new server, versus incorporating a new feature in another server. Or deciding where one slew of REST API endpoints might be better packaged as a single Tool call. And more.
- Easy set up. Many MCP servers die before ever getting a chance to be used. We offer guides and a frustration-free experience to get going with our MCP servers inside your favorite MCP clients.
- Time savings. By minimizing the number of tool chain steps or conversational turns you need to accomplish a task, our MCP servers will save you (and your agents) time waiting for a task to be completed.
- Inference cost savings. By minimizing the number of tokens you need to consume to a accomplish a task, our MCP servers will save you on your LLM inference bills.
- Reliability. You should have confidence that you can deploy our servers in a production application serving mass market consumers or business clients.
- Future-proof. We sit on the bleeding edge of the MCP specification, working to push the ecosystem forward. As such, you can be sure that if you commit to baking our server into your workflow, it will self-improve over time to take advantage of the latest and greatest MCP features.
