Unified Jobs MCP Server

Unified Jobs MCP Server

A zero-dependency Model Context Protocol server that gives an AI agent one thing no single-source jobs tool does: a cross-source, deduplicated jobs feed. It queries applicant-tracking systems, the LinkedIn public guest search, and the Hacker News "Who is hiring?" thread, then collapses the same role seen on several sources into one canonical record — with a sources[] array and a union of the richest salary, longest description, and earliest post date. The agent gets a clean list instead of three overlapping ones plus a dedup problem of its own.

• No API key, no account, no login. All data comes from keyless public endpoints.
• Zero dependencies. Hand-rolled spec-conformant JSON-RPC 2.0 over stdio — no SDK, no transitive package tree in your agent's trust boundary. Installs and boots instantly under npx.
• Public postings only. No member data, no PII beyond public job fields.

Install

Claude Desktop (claude_desktop_config.json) / Cursor / Cline / Continue:

{
  "mcpServers": {
    "unified-jobs": {
      "command": "npx",
      "args": ["-y", "github:rezearcher/unified-jobs-mcp"]
    }
  }
}

Or run it directly:

npx -y github:rezearcher/unified-jobs-mcp

Tools

search_unified_jobs

The cross-source feed. Pull one or more companies' ATS boards (companies[]), search LinkedIn (keywords + location), and/or the current HN thread — in a single call — and get back one deduplicated list. The same role on several sources merges into one record:

{
  "title": "Backend Software Engineer - Infrastructure",
  "company": "Palantir",
  "location": "United States",
  "salary": "$135,000 - $200,000 / yr",
  "posted_at": "2026-10-14T00:00:00.000Z",
  "sources": [
    { "source_platform": "lever",    "url": "https://jobs.lever.co/palantir/..." },
    { "source_platform": "linkedin", "url": "https://www.linkedin.com/jobs/view/..." }
  ],
  "primary_url": "https://jobs.lever.co/palantir/...",
  "merged": true
}

Every result set reports dedup stats: raw_source_hits, canonical_jobs, cross_source_merges, collapsed, per_source_hits.

search_hn_hiring

Just the current month's Hacker News "Ask HN: Who is hiring?" thread, normalized into the same schema. The monthly thread id is auto-discovered (it rotates on the 1st of every month) and each free-text post header is parsed into structured fields. Optional query / remoteOnly filters.

list_sources

The source families, how to address ATS companies, and exactly how the cross-source dedup behaves. No network call.

get_premium_access

The metered depth endpoints beyond the free reads above — a normalized cross-ATS compensation layer and a per-company hiring-intent signal — served pay-per-call over x402 (USDC on Base, no account/API key; the caller's wallet pays the 402 inline, a few tenths of a cent per call). Returns the base URL, each endpoint's path + price + what it adds, and the payment handshake. No network call, no payment.

Sources

Every source is wrapped so a single source failing (e.g. LinkedIn's guest endpoint rate-limiting a cloud IP) never fails the whole call — you get the sources that did return. The hosted metered version adds Indeed and rotating residential proxies for volume.

How the dedup works

• Canonical key: company | title | city, with legal suffixes stripped but seniority and role qualifiers kept — so Backend - Infrastructure and Backend - Defense stay distinct.
• Merge: scalar fields are first-non-null in source-rank order; salary is taken whole from the single richest source (kept internally consistent); posted_at is the earliest; description is the longest; sources[] accumulates every origin.
• Degrade open: a row with no derivable key is emitted as its own record with merged: false — never silently dropped.

Maintenance

A GitHub Actions smoke workflow runs a real MCP client handshake plus a live cross-source pull on every push and daily. The ATS and HN families gate it; LinkedIn is advisory (cloud-IP rate limits). A genuine upstream shape change fails the roundtrip and opens a tracking issue automatically — the feed is kept working, not left to rot.
