Descripción del creador (original en inglés)
Job postings search: find, count and read open jobs from employer career sites, with pay and links.
Estos tres nunca se combinan en una sola puntuación: las opiniones, las mediciones y la popularidad son cosas distintas.

Comparado con todos los servidores activos de esta categoría en el registro. Las estrellas solo cuentan cuando quien lo publica es dueño del repo.
Superó 1 de 1 revisiones básicas aplicables. No hemos leído el código. Antes de agregar una clave o un token, revisa qué acceso pide el servidor y usa una clave que tenga solo los permisos que necesitas.
El registro no indica ninguna clave obligatoria, aunque algunos servidores te piden iniciar sesión la primera vez que los usas.
Se ejecuta en la nube del creador. Te conectas por internet sin instalar nada, pero lo que envías pasa por los servidores del creador.
El repo de GitHub cambió por última vez –, y la última versión (1.2.0) llegó al registro hace 20 días.
Las apps compatibles con MCP, como Claude Desktop, Claude Code, Cursor y VS Code. Se conecta por URL, así que también funcionan las apps que aceptan servidores MCP remotos, como ChatGPT en modo desarrollador.

Job postings for AI agents. Headcount Labs is a hosted Model Context Protocol server that lets Claude, ChatGPT, Codex, Cursor, VS Code and other MCP clients search, count and read open jobs from employers' own career sites and the hiring platforms they use (Workday, Greenhouse, Lever, iCIMS, SmartRecruiters and others). Copies of the same opening are merged into one job, and every job keeps the link to the original posting.
There is nothing to install or run. This repository holds the connection instructions, client examples and the official MCP Registry entry (server.json, name com.headcountlabs/jobs). The server itself is hosted.
| Endpoint | Sign-in | Tools |
|---|---|---|
https://api.headcountlabs.com/mcp/public | None | 6 read-only tools; one search shows up to 250 matching jobs, 50 per page |
https://api.headcountlabs.com/mcp | OAuth 2.1 (PKCE, dynamic client registration) or an API key as a bearer token | 26 tools, including exports, the company registry, the job change feed and usage |
Both use the Streamable HTTP transport.
Pricing. Every organization gets 100,000 records free each calendar month (UTC), with no card. After that, records cost a flat $0.01 per 1,000. Counts, market insights, field lookups and doc searches are free. See headcountlabs.com/pricing.
Add the public endpoint to any MCP client. In Claude Code:
claude mcp add --transport http headcountlabs-public https://api.headcountlabs.com/mcp/public
Or call it directly. This counts every open job in the catalog:
curl -s https://api.headcountlabs.com/mcp/public \
-H "content-type: application/json" -H "accept: application/json, text/event-stream" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"count_jobs","arguments":{}}}'
Claude Code (then run /mcp and choose Authenticate):
claude mcp add --transport http headcountlabs https://api.headcountlabs.com/mcp
Or install the Claude Code plugin, which adds the server and a job-search skill:
/plugin install headcount-labs --marketplace HeadcountLabs/claude-plugin
Codex:
codex mcp add headcountlabs --url https://api.headcountlabs.com/mcp
codex mcp login headcountlabs
Cursor, Windsurf and other clients that read mcp.json: examples/mcp.json. VS Code: examples/vscode-mcp.json. claude.ai and Claude Desktop: add a custom connector with the endpoint URL. ChatGPT: headcountlabs.com/mcp/chatgpt. Grok: headcountlabs.com/mcp/grok. Clients without remote server support: run npx mcp-remote https://api.headcountlabs.com/mcp as the server command.
The public endpoint serves the first six tools in this table. The signed-in endpoint serves all of them. The full reference, with scopes and limits, is at headcountlabs.com/docs/mcp-tools.
| Tool | What it does | Uses records |
|---|---|---|
search_jobs | Finds jobs by title, keywords, company, city, state, country, work arrangement, pay and dates. Signed in, deliver_file: true writes up to 5,000 jobs to a file. | Yes |
count_jobs | Counts the jobs that match a set of filters, optionally grouped by employer. | No |
get_job | Reads one job with every linked posting and its source links. | Yes |
market_insights | Pay, top employers, remote share, metros, jobs by state and more, from a dated snapshot. | No |
list_fields | Finds the filters and job fields that match your words, such as "pay" or "remote". | No |
search_docs | Returns the best-matching sections of the Headcount Labs docs. | No |
read_file | Pages through a file that search_jobs delivered, for 24 hours. | No |
verify_jobs | Re-opens a random sample of original postings and checks link, status, title, employer, location and pay. | Sampled jobs |
compare_sources | Matches your own job list against Headcount Labs, row by row. | Matched jobs |
search_jobs_json, search_jobs_dsl | The same search with a JSON body or Elasticsearch-style clauses. | Yes |
list_job_changes | New, changed and closed jobs since a time or cursor. | Yes |
list_companies, search_companies, get_company, list_company_jobs | The company registry and each company's jobs (needs the companies:read scope). | Jobs only |
create_job_export, list_job_exports, get_job_export, read_job_export_file | Asynchronous exports of up to 100,000 jobs. | Completed exports |
get_usage, get_overage, get_usage_requests, get_usage_analytics | Your plan, records used and left, overage status and request reports. | No |
set_confirmation_level, set_overage | How large a search may be before the agent must ask you, and overage billing on or off. Agents change them only when you ask. | No |
Every tool carries a title and readOnlyHint or destructiveHint annotations. The tools read job data. They can't apply to jobs or contact employers.
search_jobs returns a short summary of each job: rank, job_id, the employer-written title, employer and a 200-character snippet (in job_ad), locations, work arrangement, pay with its period, dates and the posting and apply links. Pass view: "full", name the fields you need, or call get_job for every field. Ten typical searches came to 62% fewer tokens than with every field.untrusted_content notice, and the server tells the AI never to follow instructions inside a job ad. Hidden text (zero-width and text-direction characters, HTML comments, hidden elements) is removed before it is sent.invalid_arguments with each problem's field, what is wrong, the accepted values or the nearest valid name (did_you_mean), and a working example. Rate-limit and overload errors give retry_after_seconds.limit is the page size (10 to 100, default 50) and max_results is the most results one search returns across all its pages (10 to 1,000, default 250). They apply to search_jobs, search_jobs_json, search_jobs_dsl, list_company_jobs, list_companies, search_companies and list_job_changes. Set both on the first call and keep them the same on every page, because the cursor carries them. A search that reaches the cap returns next_cursor: null and a note. The no-account endpoint pages 1 to 50 jobs (default 10, or 1 to 10 with full descriptions) and stops at 250.search_jobs also shows the jobs as cards with pay, remote and location filters and an Apply button that opens the original posting. Other clients get the normal result.Open jobs read from employer career sites and hiring platforms, refreshed continuously, with closed jobs removed. Each job carries the employer, title, locations, work arrangement, pay as the employer published it, dates, and the posting and apply links.
Your client sends search filters and job IDs to api.headcountlabs.com and gets job data back. Headcount Labs keeps only the usage counts needed for billing. See the privacy policy and terms.
