GTM Otto MCP
Give Claude a LinkedIn seat that works while you sleep.
GTM Otto is self-driving LinkedIn prospecting. From Claude, Cursor or ChatGPT you
describe who you want to meet; GTM Otto finds them daily, warms them up from your
own LinkedIn account (visit, like, comment), invites them, and opens the
conversation. Nothing is said without you.
This repository is the public home of the GTM Otto MCP server: the registry
manifest (server.json), the Claude Code plugin with eight skills, the tool
reference and the onboarding guide. The server itself runs at
https://agent.gtmotto.com/mcp (Streamable HTTP).
Release status (2026-09-22): listed on the official MCP Registry as
com.gtmotto/linkedin
(manifest 1.2.1). https://agent.gtmotto.com/mcp answers initialize with no
credentials; OAuth is served at /.well-known/oauth-protected-resource
(authorization server clerk.gtmotto.com); 21 tools are deployed, including
gtm_connect_linkedin and the three approval tools.
What it is, in one paragraph
Every other LinkedIn MCP is a remote control for a tool you still have to operate:
lists to upload, sequences to build, seats to rotate. GTM Otto is the only one where
the outreach keeps running after the chat ends. A play is an ICP plus up to five
sourcing lanes plus an autonomy level. The server exposes 21 tools and,
deliberately, no send verb: the agent can set up, size, preview, launch, pause and
review a play, and it can approve or reject one drafted message at a time, but it
cannot write to a stranger on your behalf.
Install
The endpoint is the same everywhere: https://agent.gtmotto.com/mcp.
Authentication. Add the server with no credentials. The first time the agent
calls a protected tool, the client shows a Connect card; sign in (or sign up) in
the popup and the call is retried. Scripts and clients that cannot do OAuth can send
an API key instead: Authorization: Bearer gtm_sk_..., minted at
app.gtmotto.com/connect.
Claude (web and desktop)
Settings, then Connectors, then Add custom connector. Name it GTM Otto, paste
https://agent.gtmotto.com/mcp, save. Start a chat and say what you want; the
Connect card appears on the first protected call.
Claude Code
Then /mcp inside a session to authenticate in the browser. To use an API key
instead:
Cursor

where the config value is the base64 of {"url":"https://agent.gtmotto.com/mcp"}.
By hand, add this to .cursor/mcp.json:
ChatGPT
Settings, then Connectors, then Create (developer mode must be on). Name
GTM Otto, URL https://agent.gtmotto.com/mcp, authentication OAuth. Enable the
connector in a chat from the tools menu.
Any other client
Any MCP client that speaks Streamable HTTP works: point it at
https://agent.gtmotto.com/mcp, with OAuth or the Authorization header above.
n8n, Windsurf, VS Code and the reference mcp-remote shim all fit.
Skills for Claude Code
The gtm-otto plugin connects the server and adds eight skills that turn a sentence
into a running play:
Each skill names the exact tools and arguments it calls, what to show you, and where
it stops to ask.
Example prompts
- "Find me CFOs at Swiss fintechs and set up a play, but do not launch it yet."
- "People on LinkedIn complaining about paying 100 euros a month for Sales Navigator. Build a Post discovery lane on that and show me a sample."
- "Take every company that replied to my Instantly campaign 'Q3 agencies' and add them to the LinkedIn play."
- "Review my play 'Fintech CFOs' for the week and tell me what to change."
- "Is my LinkedIn account safe at the current daily cap?"
Tools
Full reference with arguments: docs/tools.md.
What it deliberately does not do
- No send verb. No invite, DM, comment or like tool. The agent configures the
play; GTM Otto runs it from your account on its own cadence; anything that speaks
waits for your approval, one message at a time, in the chat or in the cockpit.
- Nothing runs inside a write. Configuring a lane is not switching it on, and
switching it on does not run it. A lane runs once per 24 hours on the 5-minute
tick, when the play is active and not paused.
gtm_preview_source is free of side
effects; gtm_run_source spends real budget and is only called when you asked.
- No launching without you. The agent never activates a play, resumes a paused
one, or runs a lane unless you asked for it in the conversation. Activation acts
from your own LinkedIn account.
- No lead browsing, no autonomy changes after creation, no delete.
- No list of people. The server takes companies (
account_list, at most 100)
and post URLs, never a CSV of individual LinkedIn profiles.
- Warm-up is real. The first invites land about two days after activation.
The silent days are the product working, not a bug.

The free skills
The playbooks that need nothing but LinkedIn (find buyers in comments, ICP to a
Sales Navigator search, hiring-signal prospecting by hand, LinkedIn limits, the
comment and invite writer) live in gtmotto/gtm-skills.
That repository registers no server and needs no account; each of its skills ends
with a pointer to the skill here that runs the same recipe daily.
Contributing
This repository is mirrored out of the GTM Otto monorepo. Issues and pull
requests are welcome here and are read; fixes are applied upstream and land in the
next mirror, so a PR may be closed with a "merged upstream" note rather than merged
in place. Keep prose free of em dashes, and never describe the product as an
automated sales rep of any kind: it is self-driving LinkedIn prospecting.
