End of Life

Is this version still supported? End of Life reads a project's Dockerfile, version files, manifests and CI workflows, finds every runtime, database and OS version it pins, and says for each: still supported, security fixes only, paid extended support only, or end of life, with the dates, the days left, the latest patch, the newest version to move to, and the smallest jump that still gets fixes.

Coding agents pick versions from memory: they write FROM node:18 or python-version: "3.8" years after those stopped getting security fixes. This server answers from endoflife.date (470+ products) and finds versions where they hide: python:3.8-slim-bullseye is Python 3.8 on Debian 11, node:18-alpine3.17 carries Alpine 3.17, .nvmrc may say lts/hydrogen (Node.js 18), runs-on: ubuntu-20.04 pins an OS.

Status is computed from the dates on the day you ask, not from stored flags. For a range (>=3.8, ^18.12), the lowest version it allows is checked: it is the oldest version the project still promises to run on.

claude mcp add end-of-life -- npx -y end-of-life-mcp

Claude Desktop: download end-of-life-mcp-<version>.mcpb from the latest release and open it. The bundle is signed; verify it with gh attestation verify <file> --repo arhancanli/end-of-life-mcp.

Any other client (Windsurf, Zed, Cline, Continue and others), in its MCP config file:

{
  "mcpServers": {
    "end-of-life": {
      "command": "npx",
      "args": [
        "-y",
        "end-of-life-mcp"
      ]
    }
  }
}

Docker

docker build -t end-of-life-mcp https://github.com/arhancanli/end-of-life-mcp.git && docker run -i --rm end-of-life-mcp

Hosted (Streamable HTTP): node src/server.mjs --http serves stateless MCP at POST /mcp (port from PORT, default 3000).

Example

An agent calls check_project with:

{
  "files": [
    {
      "path": "Dockerfile",
      "content": "FROM node:18-alpine3.17 AS build\nFROM python:3.8-slim-bullseye\n"
    },
    {
      "path": ".nvmrc",
      "content": "lts/hydrogen\n"
    },
    {
      "path": ".github/workflows/ci.yml",
      "content": "jobs:\n  test:\n    runs-on: ubuntu-20.04\n    strategy:\n      matrix:\n        node: [20, 22, 24]\n"
    },
    {
      "path": "pyproject.toml",
      "content": "[project]\nrequires-python = \">=3.10\"\n"
    },
    {
      "path": "README.md",
      "content": "hello"
    }
  ]
}

and gets back (recorded from the live server on 2026-09-26):

Tools

Files check_project reads: Dockerfile and Containerfile (FROM lines, including the OS in tags such as -alpine3.19 and -bookworm), .nvmrc, .node-version, .python-version, .ruby-version, runtime.txt, .tool-versions, package.json (engines, volta), pyproject.toml (requires-python, Poetry), go.mod (go, toolchain), composer.json, Gemfile, global.json and GitHub Actions workflows (setup-* versions, matrices, runs-on).

How it behaves

• Read-only: no tool changes anything outside this process; files are read as text, never run.

• Network: HTTPS only, to the hosts listed in package.json under factory.allowHosts, with a deadline, a size cap and bounded retries; a stalled read is retried. Nothing else is contacted, and nothing is logged except unexpected failures (to stderr, without your inputs).

• Answers are cached for 12 hours.

• Results are compact JSON with a matching output schema, worst status first.

Benchmark

Measured 2026-09-26 with gpt-5.4-mini, 10 fixed tasks graded by fixed checks (bench/tasks.json, raw results in bench/results/).

Performance

Measured 2026-09-26 from Dubai, home connection against the live upstream, Node 24.19.0 (bench/perf.json, scripts/perf.mjs in the factory).

First call: a fresh server process, including the TLS connection and the upstream's own time. Repeat: the same call again, answered from the in-process cache, so it shows this server's own overhead.

Tool definitions the model reads on every turn (name, description, input schema): 1,706 characters, against 6,734 for endoflife-mcp, the only published end-of-life server. The full tool list, with the output schemas and annotations clients use to validate results, is 3,165 characters (8,958 for the alternative).
