Job Search MCP Server

job-search-mcp

A personal job-search assistant for Claude Desktop. You ask Claude to find jobs; it searches the real job boards, scores each one 0–100 for how well it fits you, and shows them on a ranked board you can triage with one click. Everything runs locally — no API keys, no accounts required.

It's an MCP App: a small server Claude Desktop talks to, plus an inline board that renders right in the chat.

Scope: it's tuned for US software-engineering roles (the built-in sources and role filters target US tech employers). Other fields or regions will return sparse results.

Works in: built and tested for Claude Desktop. It should also work in other MCP clients that both run a local (stdio) server and render MCP App UIs, such as VS Code (Copilot), Cursor, or Goose (untested). Remote-only clients (ChatGPT, Claude on web/mobile) can't launch a local server, so they won't work.

What it does

• Searches real job boards — LinkedIn plus 8 ATS/job sources (Greenhouse, Lever, Ashby, Workday, SmartRecruiters, Hacker News, RemoteOK, Remotive), using your target roles and location.
• Scores each job for you — Claude reads the full description and gives it a 0–100 fit score with a one-line reason, weighing your skills, years of experience, seniority fit, and the role.
• Lets you triage fast — Apply / Skip on each card, or in bulk ("dismiss everything under 60").
• Remembers — keeps a running shortlist, a tracker of what you've applied to, and won't show you the same job twice (for 6 months).

Setup

1. Tell Claude Desktop about it. Open your config file:

• Windows: %APPDATA%\Claude\claude_desktop_config.json
• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

Add this under "mcpServers" — npx fetches the published package for you, no cloning or building required:

{
  "mcpServers": {
    "job-search": {
      "command": "npx",
      "args": ["-y", "@servation/job-search-mcp"]
    }
  }
}

2. Fully quit and reopen Claude Desktop (on Windows, quit it from the system tray — closing the window isn't enough). That's it.

npm install
npm run build

Then point the config at this folder's dist/main.js instead:

{
  "mcpServers": {
    "job-search": {
      "command": "node",
      "args": ["D:\\job-search-mcp\\dist\\main.js"]
    }
  }
}

How to use it

Just talk to Claude. For example:

• "Save my profile" — paste your resume first; Claude pulls out your skills, roles, years, and location so searches and scoring are tailored to you.
• "Find backend engineer jobs in California, senior level, posted this week."
• "Find low-applicant jobs" — adds LinkedIn's early-applicant filter.
• "Dismiss everything under 60."
• "Show what I've applied to."
• "Re-score the board."

A typical first run: save your profile → "find jobs" → Claude scores them and shows the ranked board → you Apply/Skip.

The board

The board is a running shortlist. A job stays on it until you Apply (moves to your tracker) or Skip (hidden for good). New searches automatically skip jobs already on the board, in your tracker, dismissed, or shown in the last 6 months — so you never see the same listing twice in a row.

Click Applied or Skip on a card, or ask Claude to do it. Triaged in the widget, it sticks.

Tools (for reference)

You rarely call these by name — Claude picks the right one — but here's what's under the hood:

---

Where your data lives

One JSON file on your machine — no cloud, nothing sent anywhere except the job boards you search:

• Installed: ~/.job-search-mcp/jobs.json
• Running from source: ./data/jobs.json
• Override with the JOB_SEARCH_MCP_DATA environment variable.

---

Optional: LinkedIn Premium mode

By default LinkedIn uses its public guest endpoints: no login and no account-login risk, and you already get full job descriptions. Note that automated access still runs from your own IP and is against LinkedIn's User Agreement even in guest mode, so use it at your discretion. If you want richer/Premium data, you can use your logged-in account by adding an env block to the server config:

"job-search": {
  "command": "npx",
  "args": ["-y", "@servation/job-search-mcp"],
  "env": {
    "LINKEDIN_LI_AT": "<your li_at cookie>",
    "LINKEDIN_JSESSIONID": "ajax:1234567890123456789"
  }
}

Get both cookies from a logged-in linkedin.com tab → DevTools → Application → Cookies.

⚠️ Heads up: this is against LinkedIn's Terms of Service and can get your account flagged or restricted. The cookies also expire about monthly and LinkedIn's internal endpoints change without notice. If anything fails it falls back to guest mode automatically. Leave the env block out to stay fully safe (guest-only).

How scoring works

Claude (the host model) does the scoring directly — it reads each description and judges fit, which is well-calibrated. A deterministic formula (computeMatchScore in scoring.ts) is kept as a fallback for anyone running a weaker local model that tends to over-rank everything; it's not active by default.

Development

npm run typecheck    # type-check UI + server
npm run build        # build the UI bundle (vite single-file) + compile the server (tsc)
npm run serve:stdio  # run the server from source (tsx) for local testing

The server is stdio-only (main.ts → server.ts); the UI is a React app bundled to a single inlined HTML file (src/mcp-app.tsx → dist/mcp-app.html) that the server serves as a ui:// resource.
