Clean Harbors Careers Job Query API
Unauthenticated JSON API over Clean Harbors' open positions, served from the company's own careers host and documented by the company in its published llms.txt. One HTTP GET endpoint selects among four operations with a `tool` query parameter — search_jobs, get_job, list_departments and list_locations — and returns paged JSON. A bare GET returns a self-describing tool manifest. All four operations were called anonymously on 2026-09-05 and returned HTTP 200; search_jobs reported 1,023 open requisitions. Despite the /api/mcp/ path this is not an MCP server: a JSON-RPC tools/list POST returns 405. The careers platform is AppVault; the host, the data and the postings are Clean Harbors'.
