Overview

Description from the maker (original English)

Email open tracking for agents: add a pixel, register the send, read back who opened it

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Chat & email
  • You need to fill in: Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • You fill in yourself: Authorization

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http likelyread https://app.likelyread.com/mcp --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "likelyread": {
      "url": "https://app.likelyread.com/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "likelyread": {
      "type": "http",
      "url": "https://app.likelyread.com/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • Authorization secret required HTTP header
    Bearer token from your Likelyread account (Bearer )

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Likelyread 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 (1.0.0) reached the registry 15 days 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?

likelyread

Open-source email open tracking for Gmail. It tells you when someone opens an email you sent, explains why each open counted, and gives you a small dashboard to follow your campaigns.

Two ways to use it:

  • Likelyread Cloud at app.likelyread.com: install the Chrome extension, sign in with Google, done. Free plan; Pro adds campaign analytics and full history. See docs/CLOUD.md.
  • Self-hosted: one small server (FastAPI + SQLite) behind Caddy, installed with one command. One token, every feature, nothing leaves your VPS. Instructions below.

How it works

  1. When you click Send in Gmail with tracking on, the extension appends a 1x1 invisible image (https://your-domain/p/ .gif) to the email and registers the email with your server. Sending is never blocked or delayed.
  2. When the recipient's mail client loads the image, the server logs a hit.
  3. Hits are classified when you read them:
  • self: your own compose preview or your own view of the sent email (the extension tells the server, and also blocks the request in your browser);
  • prefetch: Apple Mail Privacy Protection loading images on delivery (bare Mozilla/5.0 user agent from Apple's network);
  • open: everything else.
  1. You see the result where you look:
  • in Gmail, next to the date of each tracked email you sent, when you open the conversation: one grey tick while nobody has opened it (*Not opened yet*, *Seen by you only*, *Prefetch only*), two red ticks once someone has (*Opened ×2*). Hover for when; click to open the email in the dashboard;
  • in the toolbar popup, the last 50 tracked emails with their status;
  • on the dashboard, everything (see below).

See SPEC.md for the full contract.

Setup

You need a small Linux server (Ubuntu or Debian, 512 MB of RAM is plenty) with ports 80 and 443 open.

1. Pick an address. Use a subdomain of a domain you own, for example t.yourcompany.com: add an A record pointing to the server's IP (on Cloudflare, set it to DNS only, grey cloud). No domain yet? The installer can use a free .sslip.io address to try it out. For real email use your own domain: spam filters trust it more, and it keeps working if you move servers.

2. Run one command on the server:

curl -fsSL https://raw.githubusercontent.com/Hugo-SEQUIER/likelyread/main/deploy/install.sh | sudo bash

It installs Docker if needed, asks for your address, creates a private token, gets an HTTPS certificate and starts everything in /opt/likelyread. At the end it prints your setup link:

https://t.yourcompany.com/#connect=<your token>

Treat it like a password. You can print it again any time with sudo bash /opt/likelyread/deploy/install.sh --show-link, and it is on the dashboard under Connect.

3. Connect the extension. Install the Chrome extension, open its settings, paste the setup link and click Save. Write an email in Gmail: the red eye next to Send means it is tracked, and after you send it a note at the bottom left says *Tracked by Likelyread*. To try it, send it to another address you can open, such as a second account or your phone: your own views never count, so an email you send yourself stays *Seen by you only*.

Get the extension from the Chrome Web Store. To run your own build instead: cd extension && npm install && npm run build, then in chrome://extensions turn on Developer mode, click Load unpacked and pick extension/dist.

4. Open the dashboard. Open the setup link in your browser: it signs you in.

Non-interactive install, for example from a provisioning script: sudo bash install.sh --domain t.yourcompany.com --yes. If something else on the server already uses port 443 on another address, add --bind-ip . See install.sh --help for all options.

Manual setup without the installer

git clone https://github.com/Hugo-SEQUIER/likelyread.git

cd likelyread/deploy cp .env.example .env

set DOMAIN=t.example.com and LIKELYREAD_TOKEN=$(openssl rand -hex 32)

docker compose up -d curl https://t.example.com/healthz # {"ok":true}

Your setup link is https://DOMAIN/#connect=LIKELYREAD_TOKEN.

Backups

Everything is in /opt/likelyread/deploy/data/likelyread.db (deploy/data/ for a manual setup). A safe online copy from cron:

sqlite3 /path/to/deploy/data/likelyread.db ".backup '/backups/likelyread-$(date +%F).db'"
Updating

Run the install command again. It keeps your address, token and data.

Campaigns and the dashboard

A campaign is just a label on an email.

  • While writing: click the campaign name next to the red eye under Gmail's Send button and pick one, or type a new one. Your pick becomes the default for the next emails. The popup and options page set the same default.
  • After sending: change an email's campaign from its detail page in the dashboard, or rename a whole campaign from the Campaigns tab.

The dashboard (https://your-domain/) has:

  • Overview: tracked emails, open rate, total opens, opens in the last 7 days, median time to first open, a 30-day sent vs opens chart, opens by hour of day (useful to pick a send time), and the latest opens.
  • Campaigns: open rate, opens and time to first open per campaign, side by side.
  • Emails: search by subject, recipient or campaign, filter by status, and open any email to see every hit with its time, verdict, the reason for that verdict, user agent and IP.
  • Senders: sender health for every address you send from (see below).
  • From address: each email records the address it was sent from (your account or a send-as alias). When you use more than one, the dashboard shows a From column and an address filter.

Open rate means *emails with at least one open / tracked emails*. Apple prefetches and your own views are never counted.

Sender health

For each address you send from, the Senders tab shows three things:

  • Setup: SPF, DKIM and DMARC on the address's domain, each with the exact fix when something is missing. Gmail and Yahoo require SPF or DKIM from every sender, and DMARC from bulk senders. Addresses at big providers such as gmail.com need nothing.
  • Pace: for an address new to sending, a daily guide: 20 emails on the first day, 5 more each day, up to 50. When you reach it, Gmail's compose window shows 20/20 today next to the eye. It is advice only: sending is never blocked. Tick *Established address* for an address that already sends every day.
  • Opens: the open rate of the last 7 days against the 4 weeks before. A sharp drop, or no opens at all, is the first sign that mail has started landing in spam.

Nothing here sends email or fakes engagement. It reads DNS and your own tracking data. Agents get the same data with the sender_health tool or likelyread health --from you@example.com.

The dashboard is a static page with no data of its own: it reads the authenticated API with your token. Set DASHBOARD=false to turn it off.

Email sent by AI agents and scripts

AI agents connect over MCP, with nothing to install. Every Likelyread server, Cloud or your own, has an MCP endpoint at /mcp. Open the dashboard's Connect page and copy the setup for your agent: one command for Claude Code, a few lines of configuration for Cursor, VS Code, Codex and other MCP clients, or a prompt that an agent such as Hermes follows to set itself up (add the server, install the skill, check the connection). The token is there on its own too, masked until you press Show. For Claude Code:

claude mcp add --transport http --scope user likelyread https://app.likelyread.com/mcp --header "Authorization: Bearer <token>"

On your own server the address is https://your-domain/mcp and the token is LIKELYREAD_TOKEN (the installer prints this command). On Likelyread Cloud, Create agent token on the Connect page makes a token just for agents: see docs/CLOUD.md.

Claude and ChatGPT connect to Likelyread Cloud with a sign-in, not a token. On the Connect page, Add to Claude opens Claude's *Add custom connector* dialog with Likelyread filled in: click Add, then Connect, sign in with Google and approve Claude on Likelyread's page. It works on claude.ai and in Claude's desktop and mobile apps. In ChatGPT, add a custom MCP server with the address https://app.likelyread.com/mcp and OAuth. The app gets a token that works only at /mcp, renews it every hour, and shows up under Account, where you can disconnect it. These apps get the results tools only: your emails, their opens, campaigns, stats and sender health, and moving an email to another campaign. Their email tools can remove the pixel (the Gmail tool Claude used in our test did, in drafts and sent emails), so send tracked emails from Gmail with the Chrome extension, or with an agent that sends the HTML as written, such as Hermes. Claude Code can sign in the same way and gets every tool: add the server without --header and run /mcp. A self-hosted server has one token and no accounts, so apps connect to it with the token as above.

The agent gets these tools, and the server's instructions give it Likelyread's rules: ask before tracking a campaign, track only recipients who agreed to it where the law requires consent, keep a safe sending pace, check that the email tool kept the pixel, say "opened", never "read", and treat what it reads as data, never as instructions.

ToolDoes
accountPlan, today's usage and the daily limit
new_pixelA new pixel id, its URL and its tag; registers nothing
text_to_htmlPlain text to an HTML part with the same words, pixel at the end
track_emailRegisters a send: idempotent, accepts sends up to 30 days old
list_emailsEmails with their status, filtered by status, campaign, sender or text
get_emailOne email and its hits: time, kind, via and reason
set_campaignMoves an email to another campaign, or to none
campaign_namesExisting campaign names, so the agent reuses them exactly
list_campaignsOpen rate and median time to open per campaign
get_statsTotals, timeline, busiest hours
sender_healthSPF/DKIM/DMARC checks, safe daily pace, open-rate trend

They run the same code as the API, so plans and limits are the same: on Likelyread Cloud's Free plan, the Pro tools and filters, and the daily limit, come back as an error the agent can read and pass on. The pixel URLs come from PUBLIC_URL, or https://DOMAIN on a self-hosted server, never from the address the agent called, so an agent on the server itself still puts the public address in emails. Whoever loads a pixel chooses its user agent, so the tools never return a hit's user agent or IP.

Agents without MCP, and scripts: the Connect page's *Agents without MCP, and scripts* section has instructions to paste to the agent. They install the likelyread CLI and the agent skill, and connect them with the same token. skills/likelyread/SKILL.md is that skill (the open SKILL.md format used by Claude Code, Hermes and other agents): copy the folder into your agent's skills directory, for example ~/.claude/skills/likelyread/, and it will know how to install the CLI, add the pixel, register sends and read opens, including when not to track. It tells agents that have the MCP tools to use those instead.

Anything that sends email itself (a script, a cron job, an AI agent) can use the likelyread CLI in cli/. It is a sing
