Common questions

Is GTM Otto safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.2.1) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

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

claude mcp add --transport http gtmotto https://agent.gtmotto.com/mcp

Then /mcp inside a session to authenticate in the browser. To use an API key instead:

claude mcp add --transport http gtmotto https://agent.gtmotto.com/mcp \

--header "Authorization: Bearer gtm_sk_..."

Cursor

The deeplink is cursor://anysphere.cursor-deeplink/mcp/install?name=gtmotto&config=eyJ1cmwiOiJodHRwczovL2FnZW50Lmd0bW90dG8uY29tL21jcCJ9, where the config value is the base64 of {"url":"https://agent.gtmotto.com/mcp"}. By hand, add this to .cursor/mcp.json:

"mcpServers": { "gtmotto": { "url": "https://agent.gtmotto.com/mcp" } } }

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:

/plugin marketplace add gtmotto/mcp

/plugin install gtm-otto@gtmotto

Skill	What it does
`launch-a-play`	Estimate the ICP, create a draft play, connect LinkedIn, preview each lane, confirm, activate, explain the next 48 hours.
`icp-to-play`	A sentence, a URL or a persona into the seven ICP facets, a company count, and a `people_search` lane on a new draft or an existing play.
`post-discovery`	Turn "people complaining about X on LinkedIn" into a Post discovery lane, with a worked French example.
`hiring-signals`	"Companies hiring for X" into a Job offers lane that reaches the buyer inside each hiring company, not the recruiter.
`weekly-play-review`	Stats, run history and the approval queue folded into a one-page review with concrete changes.
`instantly-to-linkedin`	With the Instantly MCP also connected: companies that opened or replied to a campaign become an account list on LinkedIn.
`heyreach-migration`	From an exported HeyReach lead list: companies to an account list, facets to the ICP, and an honest note on what does not carry over.
`linkedin-safety-check`	Seat state, daily cap and working hours turned into a plain-English health report.

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.

Tool	Scope	One line
`gtm_whoami`	read	Org, plan, lead meter, and the `next` step to follow. Start here.
`gtm_list_plays`	read	Every play with product, status, seat and pipeline spread.
`gtm_show_play`	read	One play in full: ICP, lanes, autonomy ladder, cap, working hours, seat.
`gtm_play_stats`	read	The pipeline over four windows, each with its delta versus the window before.
`gtm_linkedin_status`	read	The play's seat state and today's headroom against LinkedIn's limits.
`gtm_sources_reference`	read	The reference for every sourcing lane. Read before configuring one.
`gtm_show_sources`	read	All five lanes of a play: config, switch, blockers, last run, memory.
`gtm_source_runs`	read	Run history of one lane, newest first.
`gtm_list_approvals`	read	Drafted messages waiting for a human, with their approval ids.
`gtm_estimate_icp`	write	"About N companies match" for a candidate ICP. Writes nothing.
`gtm_create_play`	write	Create a fully configured play. Draft by default; `activate` flag.
`gtm_update_icp`	write	Change a play's seven ICP facets. Only the ones you name.
`gtm_update_play`	write	Name, goal, voice, `paused`, `status` active or draft, `dailyCap`, `workingHours`.
`gtm_configure_source`	write	Write a lane's settings (merge). Can switch it on in the same call.
`gtm_set_source`	write	Switch a lane on or off. Refused when there is nothing to run on.
`gtm_preview_source`	write	Dry-run one lane: size and a 10-person sample. No side effects.
`gtm_run_source`	write	Run one lane now. Real leads, real budget. Only when asked.
`gtm_forget_harvested_posts`	write	Clear a post lane's memory so a settings change can be re-tested. Costs.
`gtm_connect_linkedin`	write	Returns a browser link to connect the LinkedIn seat; then poll `gtm_linkedin_status`.
`gtm_approve`	write	Approve one drafted message by approval id. The client asks you first.
`gtm_reject`	write	Reject one drafted message by approval id. The client asks you first.

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.
