Tools

Seven tools in three capability groups — vendor status (51 built-in vendors across Atlassian Statuspage, Status.io, Slack, AWS Health, Google Cloud Service Health, and Firehydrant backends, normalized to one shape, + raw Statuspage URL passthrough), pure-TypeScript cert/DNS checks (any domain), and incident-response guidance:

| Tool | Description | |:-----|:------------| | devops_list_vendors | List vendors in the built-in registry, optionally filtered by name or category. Returns slug, display name, category, and status page URL. | | devops_status_check | Check the current health status for one or more vendors. Returns per-vendor indicator (none / minor / major / critical / maintenance), degraded components, and active incident summaries. | | devops_get_incidents | Fetch incident history for a vendor — active, resolved, or scheduled maintenance. Returns the full incident timeline with per-update bodies and affected components. | | devops_watch_stack | Check the health of a named vendor stack persisted in session state. Pass vendors once to save the list; subsequent calls reuse it. Returns an aggregate health rollup plus per-vendor detail. | | devops_check_certs | Inspect SSL/TLS certificate health for one or more domains via a real TLS handshake. Reports expiry, chain depth, protocol version, cipher suite, and HSTS presence. Pure TypeScript — no external API. | | devops_check_dns | Resolve DNS records and verify propagation for one or more domains across Google (8.8.8.8), Cloudflare (1.1.1.1), and Quad9 (9.9.9.9). Reports per-resolver latency and resolver discrepancies. Pure TypeScript — no external API. | | devops_suggest_action | Instruction tool — returns a tailored incident-response playbook and pre-filled follow-up tool calls given a vendor name and optional incident context. No external calls; fully deterministic. |

devops_list_vendors

Discover available vendors before running status checks or configuring a stack.

• Accepts an optional free-text query (matches name and slug, case-insensitive) and an optional category filter
• Eight categories: cloud, cdn-edge, dev-platform, data, comms, auth, monitoring, ai
• Returns slug (what to pass to other tools), display name, category, and status page URL
• 51 built-in entries — well-known public vendors with verified status endpoints (most on Atlassian Statuspage; aws, gcp, gitlab, neon, slack, and redis-cloud served through native-API adapters)

Built-in vendor registry:

| Category | Vendors | |:---------|:--------| | cloud | digitalocean, linode, aws, gcp | | cdn-edge | cloudflare, akamai | | dev-platform | gitlab, github, npm, vercel, netlify, render, fly-io, circleci, travis-ci, snyk, atlassian, figma, launchdarkly | | data | mongodb-atlas, planetscale, supabase, neon, redis-cloud, elastic, influxdb, upstash, cloudinary, segment | | comms | slack, discord, twilio, sendgrid, mailgun, hubspot, brevo, courier, loops | | auth | auth0, clerk, workos | | monitoring | datadog, sentry, new-relic, grafana-cloud, honeycomb | | ai | openai, anthropic, elevenlabs, pinecone, cohere |

Most registry entries are Atlassian Statuspage endpoints; aws (AWS Health Dashboard), gcp (Google Cloud Service Health), gitlab / neon (Status.io), slack (Slack's own status API), and redis-cloud (Firehydrant) are served through adapters that normalize into the same shapes, so every tool works identically for them. Azure remains out of the registry: its status feed is RSS with no severity or lifecycle field, so the normalized shapes cannot be filled from it without inventing values. Statuspage-compatible pages not listed here can still be reached by passing a raw base URL.

---

devops_status_check

Batch health snapshot across one or more vendors in a single call.

• Accepts registered vendor slugs (e.g., "github", "aws") or raw Atlassian Statuspage base URLs (e.g., "https://www.githubstatus.com") — mix freely
• mode: "summary" (default): indicator + degraded components + active incidents
• mode: "detailed": adds full component list and scheduled maintenance windows
• Promise.allSettled fan-out — one failing vendor does not block the rest; errors surface inline
• Results served from a 60-second in-memory cache; cached: true flag on each result

---

devops_get_incidents

Full incident timeline for a vendor with filter support.

• filter: "all" (default): incidents plus scheduled maintenances
• filter: "active": only incidents with status investigating / identified / monitoring
• filter: "resolved": only fully resolved incidents
• filter: "scheduled": only scheduled maintenance windows
• Returns per-update bodies in chronological order, affected component names, duration in minutes (resolved incidents), and a direct shortlink to the incident page
• Configurable limit (1–50) with offset for paging through longer history; a truncated result discloses the total and names the next offset to fetch
• AWS exposes only currently-open events (no history feed) — filter: "resolved" and filter: "scheduled" are always empty for aws

---

devops_watch_stack

Named, persisted vendor stack for recurring health sweeps.

• On the first call, provide vendors to define the stack — it is saved to tenant-scoped session state under stack_name
• Subsequent calls can omit vendors; the saved list is reused automatically
• Multiple stacks coexist via distinct stack_name values (e.g., "production", "data-layer")
• Aggregate health output: all_operational / degraded / partial_outage / major_outage / unknown (a vendor could not be reached — errored vendors count as unavailable and never roll up as all_operational)
• Note: stack state is in-memory; it does not persist across server restarts

---

devops_check_certs

Direct TLS handshake inspection — no external API required.

• Accepts bare hostnames (no https:// prefix) — up to 10 per call
• Reports: days to expiry (flagged warning at < 30 days, critical at < 7), certificate subject and SANs, issuer common name, chain depth, negotiated TLS version (flags 1.0 and 1.1 as insecure), cipher suite
• HSTS detection: sends a minimal HTTP/1.1 GET over the same TLS socket, reads the Strict-Transport-Security response header
• Per-domain failures are reported inline (status: "error") rather than throwing — useful partial results when checking multiple domains
• Configurable port (default 443) and timeout per domain

---

devops_check_dns

Multi-resolver DNS propagation check — no external API required.

• Queries Google (8.8.8.8), Cloudflare (1.1.1.1), and Quad9 (9.9.9.9) in parallel per domain
• Supported record types: A, AAAA, CNAME, MX, TXT, NS (defaults to A, AAAA, MX, TXT)
• Reports per-resolver latency, propagation discrepancies (where resolvers disagree), and human-readable flags
• Custom resolver list supported — pass any IP addresses to test internal DNS or resolver-specific behavior
• Up to 10 domains per call; per-domain timeouts configurable

---

devops_suggest_action

Deterministic incident-response guidance, no external calls.

• Returns a markdown playbook tailored to the vendor's category (CDN outage vs. CI/CD outage vs. auth provider outage vs. AI service outage)
• Accepts a vendor slug or display name (aws or Amazon Web Services) — resolved to the canonical slug so the pre-filled follow-up arguments stay valid
• nextToolSuggestions pre-populated with arguments from the provided context — execute in sequence to gather diagnostic data
• Optional your_domain populates cert and DNS check arguments automatically
• Optional incident_summary / affected_components prepend a targeted section to the playbook and add a component re-check when they identify a subsystem (e.g. GitHub Actions → CI/CD-prioritized steps; Cloudflare DNS → DNS/TTL guidance)
• Optional vendor_indicator — pass the indicator from devops_status_check to lead the playbook with severity-tailored urgency guidance (none / minor / major / critical / maintenance)
• Falls back to generic guidance for unrecognized vendors
• When DEVOPS_STATUS_DISABLE_ACTIVE_PROBES=true, suggestions and playbook text replace the unregistered probe tools with equivalent manual commands (dig, openssl s_client)

---

Resources and prompts

| Type | Name | Description | |:-----|:-----|:------------| | Resource | devops-status://vendors/{name} | Full registry entry for a vendor by slug — status page URL, category, API type. |

All resource data is also reachable via tools. Tool-only agents are fully supported.

---

Features

Built on @cyanheads/mcp-ts-core:

• Declarative tool and resource definitions — single file per primitive, framework handles registration and validation
• Unified error handling — handlers throw, framework catches, classifies, and formats
• Pluggable auth: none, jwt, oauth
• Swappable storage backends: in-memory, filesystem, Supabase, Cloudflare KV/R2/D1
• Structured logging with optional OpenTelemetry tracing
• STDIO and Streamable HTTP transports

DevOps-status-specific:

• No API keys required — every status backend is a public API; TLS and DNS use Node.js stdlib (node:tls, node:dns)
• 51-vendor built-in registry covering cloud, CDN, dev-platform, data, comms, auth, monitoring, and AI categories; adapter layer normalizes Status.io, Slack, AWS Health, Google Cloud Service Health, and Firehydrant backends into the Statuspage shapes; extendable via raw Statuspage URL passthrough
• 60-second in-memory cache on status reads shared across all tenants — prevents thundering-herd on batch calls
• devops_watch_stack persists named vendor lists in tenant-scoped state for repeat morning checks or pre-deploy sweeps
• devops_suggest_action dispatches category-specific playbooks deterministically — no LLM sampling dependency, works in all clients

Agent-friendly output:

• Batch tools (devops_status_check, devops_watch_stack, devops_check_certs, devops_check_dns) use Promise.allSettled — one failing target never blocks the rest; errors surface as inline error fields
• cached: true / checked_at on every status result — agents know when data was fetched
• Discriminated indicator and status enums (none / minor / major / critical / maintenance; operational / degraded_performance / partial_outage / major_outage / under_maintenance) — callers branch on data, not string parsing
• nextToolSuggestions in devops_suggest_action pre-fills tool arguments from incident context — agents can execute the playbook mechanically

Getting started

Public Hosted Instance

A public instance is available at https://devops-status.caseyjhand.com/mcp — no installation required. Point any MCP client at it via Streamable HTTP:

{
  "mcpServers": {
    "devops-status-mcp-server": {
      "type": "streamable-http",
      "url": "https://devops-status.caseyjhand.com/mcp"
    }
  }
}

Self-Hosted / Local

No API key required. Add the following to your MCP client configuration file:

{
  "mcpServers": {
    "devops-status-mcp-server": {
      "type": "stdio",
      "command": "bunx",
      "args": ["@cyanheads/devops-status-mcp-server@latest"],
      "env": {
        "MCP_TRANSPORT_TYPE": "stdio",
        "MCP_LOG_LEVEL": "info"
      }
    }
  }
}

Or with npx (no Bun required):

{
  "mcpServers": {
    "devops-status-mcp-server": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@cyanheads/devops-status-mcp-server@latest"],
      "env": {
        "MCP_TRANSPORT_TYPE": "stdio",
        "MCP_LOG_LEVEL": "info"
      }
    }
  }
}

Or with Docker:

Running the server

Local development

• Build and run:

  bun run rebuild
  bun run start:stdio
  # or
  bun run start:http

• Run checks and tests:

  bun run devcheck   # Lint, format, typecheck, security
  bun run test       # Vitest test suite
  bun run lint:mcp   # Validate MCP definitions against spec

Docker

docker build -t devops-status-mcp-server .
docker run --rm -p 3010:3010 devops-status-mcp-server

The Dockerfile defaults to HTTP transport, stateless session mode, and logs to /var/log/devops-status-mcp-server. OpenTelemetry peer dependencies are installed by default — build with --build-arg OTEL_ENABLED=false to omit them.

Development guide

See CLAUDE.md for development guidelines and architectural rules. The short version:

• Handlers throw, framework catches — no try/catch in tool logic
• Use ctx.log for request-scoped logging, ctx.state for tenant-scoped storage
• Register new tools and resources via the barrels in src/mcp-server/*/definitions/index.ts
• devops_check_certs and devops_check_dns use only Node.js stdlib — add no external deps for these paths
