Introduction

Your AI agent can write outreach, schedule meetings, and qualify leads. But the moment it needs real data — a prospect’s LinkedIn URL, a verified email, evidence that a company is hiring SDRs, follower spikes on TikTok — it stalls. Stitching together RapidAPI calls, scraping rules, SMTP verifiers, and rate-limit logic is a project in itself.

GTM Tools is a monorepo of MCP servers that exposes that stack as a handful of tool calls. Every tool is metered in tokens, billed centrally, and reachable via MCP, REST, or CLI — so you focus on the agent loop, not the plumbing.

What is GTM Tools?

GTM Tools is a single MCP service exposing five tool categories:

Everything ships behind a single host: api.gtm-tools.sh/mcp for MCP, api.gtm-tools.sh/api/v0/{tool} for REST. One auth boundary, one billing wallet. New accounts get 100 free tokens to start.

(gtm-tools.sh itself is the docs site you’re reading — the API lives under the api. subdomain.)

What your agent can do

1. Get auth and manage billing

get_api_key gets a key via email verification. get_token_balance returns the wallet state, buy_tokens tops up via card ($1 = 100 tokens,$5 minimum), set_auto_reload configures auto top-up when the balance dips below a threshold, and list_invoices returns the purchase history. New accounts get 100 free tokens.

2. Find and act on LinkedIn

The most common starting point is get_linkedin_company_url — feed it a domain and it returns the company’s LinkedIn page. From there, list_linkedin_company_employees lists the workforce with boolean title filters ("(CEO OR CTO OR Founder) NOT intern"), get_linkedin_profile_url gets a profile URL from name + company, and get_linkedin_profile / get_linkedin_company get the full structured records. Once you’ve found the right person, send_linkedin_invitation and send_linkedin_message close the loop. The write and personal-data tools run through a logged-in session shared by the browser extension; list_connected_linkedin_accounts shows which sessions are connected.

3. Engage on Reddit

21 tools covering the full engagement loop. Discover: search_reddit_posts (keyword surveillance), list_subreddit_posts (daily hot/new/rising), search_reddit_subreddits (shortlist communities), get_subreddit_about (the rule-compliance gate every Reddit playbook flags as the #1 shadowban trigger). Evaluate: get_reddit_post (post + full comment tree), get_reddit_user (karma, account age, verified flags), list_reddit_user_posts (posting history — is this actually our ICP?). Engage: create_reddit_comment (reply to post or comment), create_reddit_post (submit), vote_reddit (up/down/clear), send_reddit_message (DM via Reddit’s Matrix-based Chat — works for every account, including the post-rollout cohort that can’t receive legacy PMs). Follow up: follow_reddit_post (notifications on new comments), save_reddit_thing with optional CRM-stage category label, list_reddit_saved, list_reddit_inbox. Organize: subscribe_reddit_subreddit (bulk sub/unsub), list_reddit_subscriptions, plus custom feeds (multireddits) via list_reddit_custom_feeds, list_reddit_custom_feed_posts, create_reddit_custom_feed — one feed per ICP / campaign, then daily monitoring reads the merged stream in one call. All write tools (and the gate-bypassing reads) run on a pooled session from the browser extension; list_connected_reddit_accounts shows which accounts are connected. See the Results Ranking Optimization guide for the should-I-reply gate and anti-spam style rules.

4. Verify professional emails

get_email takes a name + domain and returns a deliverable email. It generates every common pattern (first@, first.last@, flast@, etc.) and verifies each against the domain’s mail server via SMTP — no mail actually sent. Catch-all domains are flagged in the response so your agent knows when to trust the result.

5. Detect buying signals

detect_signal runs every signal in one call. The individual detectors live alongside it: signal_socials_spike (Instagram/TikTok follower jumps), signal_hiring_role / signal_hiring_support / signal_hiring_sales_rep / signal_hiring_sales_leadership / signal_hiring_sales_rep_repost (job-board scans, including reposted SDR roles as a churn signal), signal_trustpilot_negative_reviews / signal_trustpilot_negative_support_reviews / signal_trustpilot_positive_reviews, and signal_technologies_identified (stack detection on the website). set_signals_order / get_signals_order configure execution order.

Quick example

1
// 1. Get the LinkedIn page from a domain
2
const company = await fetch("https://api.gtm-tools.sh/api/v0/get_linkedin_company_url", {
3
  method: "POST",
4
  headers: {
5
    "Authorization": `Bearer ${process.env.GTM_TOOLS_API_KEY}`,
6
    "Content-Type": "application/json",
7
  },
8
  body: JSON.stringify({ domain: "siena.cx" }),
9
}).then(r => r.json());
10
11
// 2. Search senior decision-makers
12
const employees = await fetch("https://api.gtm-tools.sh/api/v0/list_linkedin_company_employees", {
13
  method: "POST",
14
  headers: {
15
    "Authorization": `Bearer ${process.env.GTM_TOOLS_API_KEY}`,
16
    "Content-Type": "application/json",
17
  },
18
  body: JSON.stringify({
19
    domain: "siena.cx",
20
    title_filters: "(CEO OR CTO OR Founder) NOT intern",
21
    limit: 10,
22
  }),
23
}).then(r => r.json());
24
25
// 3. Verify a professional email
26
const email = await fetch("https://api.gtm-tools.sh/api/v0/get_email", {
27
  method: "POST",
28
  headers: {
29
    "Authorization": `Bearer ${process.env.GTM_TOOLS_API_KEY}`,
30
    "Content-Type": "application/json",
31
  },
32
  body: JSON.stringify({ name: "Justin Mares", domain: "kettleandfire.com" }),
33
}).then(r => r.json());
34
// → { "email": "justin@kettleandfire.com", "is_catch_all": false, ... }

Same flow from the CLI:

$
gtm-tools socials company-url siena.cx
$
gtm-tools socials employees siena.cx --filter "(CEO OR CTO) NOT intern"
$
gtm-tools signals detect gymshark.com
