gtm-api is one REST API and one MCP server for LinkedIn work: search, profiles, companies, connections, messaging, posts and comments, plus a hosted browser per account so an agent acts as a real logged-in user instead of scraping.
I run product and most of the engineering. gtm-api reports 20,000+ connected accounts at under a 1% monthly ban rate.
The MCP server is the source of truth for the tool contract. The REST API, the OpenAPI spec and the docs are generated from it, so an agent and a human integrator read the same surface.
