Prometheus Alertmanager MCP Server for Claude AI integration
Prometheus Alertmanager MCP Server for Claude AI integration. The alertmanager mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 2 defined tools rather than through you.
Everything the assistant can do here goes through one of these:
Prerequisites — The Prerequisites tool exposed by this serverSetup — The package is available on npm and can be used directly with npx:You will need one environment variable: ALERTMANAGER_URL. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Installation goes through your MCP client rather than a global install: point it at alertmanager-mcp on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Plenty of monitoring and observability servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Alertmanager's toolset — Prerequisites, Setup — is a fair guide to whether it matches your workflow. It is maintained by kaznak; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
