Category: Clinics & health
You need to fill in: X-API-Key

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on the maker’s server: what you ask it goes through their server.
You fill in yourself: X-API-Key

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http faultline https://mcp.fltln.io/mcp --header 'X-API-Key: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "faultline": {
      "url": "https://mcp.fltln.io/mcp",
      "headers": {
        "X-API-Key": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

      "url": "https://mcp.fltln.io/mcp",

Common questions

Is Faultline safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: X-API-Key

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.0.0) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Mirobody, FHIR MCP Server, Google Health MCP

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 plus an Agent Skill. The server is hosted by Faultline at https://mcp.fltln.io/mcp (Streamable HTTP transport), so there's nothing to install or run yourself.

Setup

Create an API key in Faultline: Settings → API Keys. Keys look like flt_....
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_..." } } } }

Discovery without a key

You can browse the toolset before creating a key. The MCP discovery methods initialize, notifications/initialized, and tools/list work without an API key, so connector directories, registry scanners, and curious humans can see every tool's name, description, input schema, and annotations:

curl -s https://mcp.fltln.io/mcp \

-H "Content-Type: application/json" \ -H "Accept: application/json, text/event-stream" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Anything else, including every tools/call, needs a key and returns 401 without one.

Agent Skill

skills/faultline/SKILL.md is an Agent Skill that teaches Claude how to use these tools well:

Workflows: which tools to call for a health overview, "why is X slow?", incident triage and remediation, and on-call lookups.
Approval rules: read-only tools run freely; acknowledging, resolving, and running runbooks wait for your explicit go-ahead, and Claude only runs a runbook that diagnose_incident returned for that incident.

Install it alongside the MCP server:

Claude Code: copy the skills/faultline folder into ~/.claude/skills/ (all projects) or .claude/skills/ (one project).
Claude.ai / Claude Desktop: zip the faultline folder and upload it under Settings → Capabilities → Skills.

Tools

Tool	What it does
`list_services`	Monitor inventory with current status (optional status filter)
`get_service`	One service + its 10 most recent checks (for diagnosis)
`list_incidents`	Open incidents (or `status: "resolved"` for history)
`get_incident`	Full incident record: timeline, AI summary, post-mortem
`acknowledge_incident`	Acknowledge an incident, which stops further escalation
`resolve_incident`	Resolve with an optional note (recorded on the timeline and visible on your status page)
`who_is_on_call`	Current on-call per schedule, with shift end time
`list_anomalies`	Recent learned-baseline latency anomalies (observed vs baseline, z-score, hours sustained, auto-opened incident if any)
`diagnose_incident`	Recommend the next action (run runbook / escalate / resolve / wait) + candidate runbooks. Analysis only; changes nothing
`run_runbook`	Execute 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.
Keyless means read-only metadata. Requests without a key can only list the static tool definitions. They never reach Faultline's API and can't read or change any tenant data.
Approval-gated mutation. run_runbook is the only tool that changes infrastructure. Its description, and the Agent Skill, instruct 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, so one key can never see or affect another tenant's data.
