What it is

gtm-api is a LinkedIn API and MCP server for AI agents.

gtm-api is an account-based LinkedIn API. LinkedIn's official API has no endpoints for invitations, member DMs or people search, so instead you connect your own accounts and drive them through one typed contract: MCP tools for AI agents, REST for your backend. Each account runs in an isolated anti-detect cloud browser with a dedicated proxy and smart limits.

5G Proxy · per-account add-on

A premium mobile carrier route of its own, instead of a shared residential IP. For the accounts you cannot afford to lose: a founder's profile, a client's account. On by default at checkout, mix per account if you want.

5G Proxypremium 5G+$15/account/mo

Dedicated 5G mobile route. All of the account's traffic rides carrier-grade mobile IPs, the network class LinkedIn trusts most: real phones live there.
Lightning speed. Premium 5G infrastructure: faster command execution, fewer retries, fewer drops. Fewer failures means fewer anomalies, and a safer account.

FAQ

LinkedIn API questions, answered.

Does LinkedIn have an official API for messages and connection requests?

No. LinkedIn's self-serve APIs cover Sign In with LinkedIn and Share; the Marketing, Sales Navigator (SNAP), Talent and Learning APIs are partner-gated. There is no official endpoint for sending invitations, member-to-member messaging, or open people search. That gap is why account-based LinkedIn APIs such as gtm-api exist: you authorise your own accounts and drive them through one contract.

What is a LinkedIn MCP server?

An MCP (Model Context Protocol) server exposes LinkedIn to an AI agent as typed tools it can call directly. Add the gtm-api MCP server to Claude, Cursor or ChatGPT with a single API key, and the agent can search, connect, message and enrich on your accounts, instead of drafting text for you to paste in by hand.

Is LinkedIn automation safe?

It is when every account is isolated and paced. gtm-api runs each account in its own anti-detect cloud browser with a dedicated residential proxy, Single Session Protection, warm-up curves and health-aware smart limits, so no automation can outrun the account it runs on. It is the same stack behind 20,000+ LinkedIn accounts at under a 1% ban rate.

Safe LinkedIn automation →

What are the LinkedIn connection request limits in 2026?

Roughly 100 invitations per week on free and Premium accounts and 150-200 with Sales Navigator, measured on a rolling 7-day window. A safe daily pace is about 15-20 on free and Premium and 30-40 on Sales Navigator; unanswered invites auto-withdraw after roughly six weeks, and total connections are capped at 30,000. gtm-api enforces this as per-account smart limits, ramping new accounts up instead of starting at the ceiling.

LinkedIn connection limits →

How much does gtm-api cost?

From $39 per connected account per month, scaling down to $10 per account at volume. Unlimited API calls and actions are included: no per-action fees, no counters, no feature gates. Annual billing: pay for 12 months, get 15. A free plan gives you one connected account with the full UI, API, MCP and CLI, no card. 5G Proxy is the per-account add-on at $15 a month: the account runs on a dedicated premium 5G mobile route, so commands execute faster with fewer retries and fewer drops.
