sanitycheck-mcp

An MCP server that gives AI coding agents awareness of internet and service health. When your deploys fail, APIs timeout, or your AI assistant starts acting weird, these tools help figure out if it's you or if something is actually down.

Tools

is_the_internet_on_fire

Check the health of major internet infrastructure at a glance. Fetches status from 18 tracked services across cloud, CDN, devtools, AI, communications, and infrastructure categories.

Optional: category = "cloud" | "cdn" | "devtools" | "ai" | "comms" | "infra"

whats_going_on_with

Investigate a specific service in detail. Pulls official status, component health, active incidents, plus third-party reports from Downdetector and StatusGator.

Required: service = "github" | "aws" | "vercel" | "npm" | ...

Supports aliases like s3 → aws, gh → github, claude → anthropic.

how_am_i_feeling

Lets an AI model check its own provider's health and community-reported quality. Auto-detects which model is asking based on MCP client info, or accepts an explicit model parameter.

Optional: model = "claude" | "gpt" | "gemini"

Tracked Services

| Category | Services | |----------|----------| | Cloud | AWS, GCP, Azure | | CDN | Cloudflare, Fastly, Akamai | | DevTools | GitHub, GitLab, Vercel, Netlify | | AI | OpenAI, Anthropic, Google AI | | Comms | Slack, Discord | | Infra | Datadog, PagerDuty, npm |

Data Sources

• Official status pages — Atlassian Statuspage API, custom scrapers for AWS, Azure, Akamai, GCP, GitLab, Slack, PagerDuty
• Downdetector — crowd-sourced outage reports
• StatusGator — aggregated status monitoring
• AI community sites — AI Daily Check, LM Arena, IsClaudeCodeDumb, AI Stupid Level (requires headless Chrome)

Setup

Add to your MCP client config:

{
  "mcpServers": {
    "sanitycheck": {
      "command": "npx",
      "args": ["-y", "sanitycheck-mcp"]
    }
  }
}

Or with Claude Code:

claude mcp add sanitycheck -- npx -y sanitycheck-mcp

Environment Variables

| Variable | Description | |----------|-------------| | SANITYCHECK_DEBUG=1 | Enable debug logging to stderr | | SANITYCHECK_CHROME_PATH | Path to Chrome binary for headless browser features | | SANITYCHECK_DISABLE_CACHE=1 | Disable the on-disk cache for official status and aggregator fetches |
