New: native MCP for Claude, OpenClaw, Hermes & every agent

Analytics with no dashboard.

An HTTP API your code, your cron jobs, and your AI agents already know how to use. Ship the snippet, ask the agent, get the answer. Built for vibe coders and the machines that work alongside them — no charts, no funnels, no Looker license.

<script async
  src="https://api.millimetric.ai/v1/a.js"
  data-key="pk_live_…"></script>

That's it. Page views, attribution, UTM, fbclid — captured. No cookies set.

Built for the way you actually ship

Drop in a snippet. Ask an agent. Get the number.

Same JSON shape from a browser, a backend, or an LLM. No dashboards to babysit.

API-only. No dashboard.

Your analytics live where your code does — in a JSON response. Query from a notebook, a server, a Slack bot, or an agent. Skip the BI tool entirely.

Agent-native (MCP)

Claude, OpenClaw, Hermes, Cursor — anything that speaks MCP can read and write events. One key, two-way: track_event, top_sources, get_stats, query_events.

Made for vibe coders

One <script>, one curl, one MCP server. Works with Next.js, Astro, Remix, plain HTML, Bun, Workers — anywhere you can make an HTTP request.

Privacy by default

No cookies. No fingerprints. No raw IPs at rest. Respects DNT and Global Privacy Control. GDPR, UK-GDPR and CCPA out of the box.

Smart attribution

Separates Facebook social from Facebook paid, Google Ads from Google organic. Confidence labels + auditable rule IDs on every event.

Stays out of the way

1.8 KB browser SDK. p95 ingest at 42 ms on Cloudflare's edge. No bundle bloat, no waterfall, no ten-tab tracking-script-mafia.

For vibe coders

Shipping at 2 a.m. on a Tuesday? We get it.

You don't need a "data team," a 47-step funnel builder, or a quarterly review with someone who calls events "occurrences." You need to know if anyone actually clicked the thing — without breaking PageSpeed or strapping a GA4 cookie banner onto your landing page.

One snippet. Done.
Paste a single <script> tag. Page views, referrers, UTMs, fbclid, gclid — captured. Zero config, zero cookies.
Wired into your stack already
Curl from a Vercel cron. Track from a Cloudflare Worker. Pipe events from your Inngest job. Same key, same endpoint.
Boring on purpose
No re-platforming when you hit 100k MAU. No upsell calls. No surprise schema migrations the night before your launch.

For AI agents

Your agent is now a data analyst.

Every Millimetric project ships with a Model Context Protocol server. Hand your agent one key and it can write events as the user moves, and read the same data back to answer questions in natural language — no SQL, no BI tool, no human in the loop.

One key, scoped to one project
Read keys (rk_live_*) and write keys (pk_live_*) are separate. Revoke from the API, rotate from the API.
Tools an LLM actually likes
track_event, get_stats, top_sources, top_pages, query_events, list_projects. Strict JSON schemas — no prompt-engineering tax.
Bring your own agent
Drop the MCP URL into Claude Desktop, Cursor, Cline, OpenClaw, Hermes, or anything else that speaks the protocol.

See the agent setup MCP docs

Smart attribution

The Facebook social-vs-paid split, finally solved.

Most tools dump everything into a single "facebook" bucket. Millimetric runs a deterministic, ordered classifier on every event and tells you exactly which rule fired — auditable, re-classifiable, and tunable per project.

Integrations

Three shapes, one API.

Mix and match. Use them all in the same product without doubling up infrastructure.

Browser

Snippet or npm. 1.8 KB gzipped. Auto-pageview, SPA support, sendBeacon on unload.

tscopy

import { init, track } from "@millimetric/track";

init({ key: "pk_live_…" });
track("signup", { plan: "free" });

Server

Node / Bun / Deno SDK — or just curl. Batches and retries built in.

tscopy

import { init, track } from "@millimetric/track-node";

init({ key: process.env.AOA_SK!, host });
track({ event: "purchase",
  user_id: user.id });

AI agent (MCP)

Any MCP-speaking agent. Emit events and query analytics through the same key.

jsoncopy

// tools/call → top_sources
{ "from": "2026-05-01T00:00:00Z",
  "to":   "2026-06-01T00:00:00Z",
  "breakdown": "source_medium" }
