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:

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:

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") — letters, digits, hyphens, and underscores, optionally separated by single dots or slashes, 1-64 characters

• 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

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:

{
  "mcpServers": {
    "devops-status-mcp-server": {
      "type": "stdio",
      "command": "docker",
      "args": [
        "run", "-i", "--rm",
        "-e", "MCP_TRANSPORT_TYPE=stdio",
        "ghcr.io/cyanheads/devops-status-mcp-server:latest"
      ]
    }
  }
}

For Streamable HTTP, set the transport and start the server:

MCP_TRANSPORT_TYPE=http MCP_HTTP_PORT=3010 bun run start:http
# Server listens at http://localhost:3010/mcp

Prerequisites

• Bun v1.3.0 or higher (or Node.js v24+).

• No API keys or external accounts required.

Installation

1. Clone the repository:

git clone https://github.com/cyanheads/devops-status-mcp-server.git

2. Navigate into the directory:

cd devops-status-mcp-server

3. Install dependencies:

bun install

4. Configure environment:

cp .env.example .env
# edit .env if you want to override defaults

Configuration

No API keys required. All environment variables are optional.

See .env.example for the full list of optional overrides.

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.

Project structure

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
