Add in Claude

Claude opens with the name and URL filled in. You still confirm it there.

Claude Code
claude mcp add --transport http io.fltln-faultline https://mcp.fltln.io/mcp

Run in a terminal.

Faultline MCP Server

Faultline is infrastructure monitoring and incident management for DevOps/SRE teams. This repo documents faultline-mcp — Faultline's remote MCP server, which lets AI agents (Claude, Claude Code, Claude Desktop, or anything MCP-compatible) operate Faultline: check infrastructure health, inspect and act on incidents, look up who's on call, and run approved runbooks.

This repo is documentation only. The server is hosted by Faultline at https://mcp.fltln.io/mcp (Streamable HTTP transport) — there's nothing to install or run yourself.

Setup

  1. Create an API key in Faultline: Settings → API Keys. Keys look like flt_....
  2. Point your MCP client at https://mcp.fltln.io/mcp, sending the key as either X-API-Key: flt_... or Authorization: Bearer flt_....

Claude Code:

claude mcp add --transport http faultline-mcp https://mcp.fltln.io/mcp \
  --header "X-API-Key: flt_..."

Clients that take raw JSON config (Claude Desktop, etc.):

{
  "mcpServers": {
    "faultline": {
      "type": "http",
      "url": "https://mcp.fltln.io/mcp",
      "headers": { "X-API-Key": "flt_..." }
    }
  }
}

Tools

ToolWhat it does
list_servicesMonitor inventory with current status (optional status filter)
get_serviceOne service + its 10 most recent checks (for diagnosis)
list_incidentsOpen incidents (or status: "resolved" for history)
get_incidentFull incident record: timeline, AI summary, post-mortem
acknowledge_incidentAcknowledge an incident — stops further escalation
resolve_incidentResolve with an optional note (recorded on the timeline)
who_is_on_callCurrent on-call per schedule, with shift end time
list_anomaliesRecent learned-baseline latency anomalies (observed vs baseline, z-score, hours sustained, auto-opened incident if any)
diagnose_incidentRecommend the next action (run runbook / escalate / resolve / wait) + candidate runbooks. Analysis only — changes nothing
run_runbookExecute one chosen runbook against an incident — mutates infrastructure (can restart/scale services)

Security

  • Scoped to your API key. The server never stores your key — it's used only for the duration of each request, proxied straight through to Faultline's API.
  • Approval-gated mutation. run_runbook is the only tool that changes infrastructure. Its description instructs the calling agent to use it only after diagnose_incident recommended it and you've explicitly confirmed.
  • Tenant-isolated. Every request is scoped to the tenant that owns the API key — one key can never see or affect another tenant's data.
