Overview

Description from the maker (original English)

Read and manage fnlowl widgets, leads, email sequences and analytics from an AI assistant.

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: Marketing & social media

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.
  • The registry lists no key to fill in.

You need

Which app do you use?

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

Works in Claude on the web, desktop and mobile:

  1. Open Settings → Connectors
  2. Press Add custom connector
  3. Paste the address below and press Add
  4. If it asks you to sign in, sign in with the maker

Open in Cursor

Or copy the settings yourself

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

  "mcpServers": {
    "fnlowl": {
      "url": "https://api.fnlowl.com/v1/mcp"
    }
  }
}

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": {
    "fnlowl": {
      "type": "http",
      "url": "https://api.fnlowl.com/v1/mcp"
    }
  }
}

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.

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save
  4. If it asks you to sign in, sign in with the maker

Menu names can differ slightly by plan and over time.

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

Common questions

Is fnlowl 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?

The registry does not list a required key, though some servers ask you to sign in on first use.

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 (1.0.1) reached the registry 35 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?

In the same category: MCP YouTube Transcript, Google Analytics MCP, BibiGPT YouTube Video Summarizer

@fnlowl/skills

Agent skills for operating fnlowl (pronounced *Funnel Owl* — Funnel Intelligence, Agentified!) — lead-capture widgets, the leads they produce, and the mail that follows.

Four skills:

  • `fnlowl-capture` — build and diagnose widgets, leads, and funnel analytics.
  • `fnlowl-follow-up-automation` — draft and review delivery, integration handoff, campaigns, and sequences.
  • `fnlowl-installation` — install embeds on generic sites, WordPress, Shopify, Webflow, and Framer.
  • `fnlowl-mcp` — connect an agent to the remote MCP surface safely.

Read them in skills/.

Install

npx skills add fnlowl/skills --list

npx skills add fnlowl/skills --global --agent claude-code npx skills add fnlowl/skills --global --agent claude-code --skill fnlowl-capture npx skills add fnlowl/skills --global --agent claude-code --skill fnlowl-follow-up-automation npx skills add fnlowl/skills --global --agent claude-code --skill fnlowl-installation npx skills add fnlowl/skills --global --agent claude-code --skill fnlowl-mcp

Name your agent with --agent (for example claude-code, codex or cursor). Without it, a non-interactive run (--yes) installs into every agent the installer supports.

Install from npm
npm i -D fnlowl-skills

npx skills experimental_sync --agent claude-code

The package is fnlowl-skills. The sync links the four skills from node_modules into your project's agent folder; name your agent with --agent.

Pin a release

Releases are tagged on GitHub. For a stable install, pin a tag instead of the default branch:

npx skills add fnlowl/skills#v0.1.0 --global --agent claude-code

The skills are versioned together as one bundle. A release that renames or removes a skill says so in its notes.

Install as a Claude Code plugin

The repo is also a plugin marketplace, so Claude Code can install it directly:

/plugin marketplace add fnlowl/skills

/plugin install fnlowl@fnlowl-plugins

How to invoke skills

PlatformTypical invocation
Claude Code/fnlowl-capture, /fnlowl-follow-up-automation, /fnlowl-installation, /fnlowl-mcp
Cursorthe same names after typing / in Agent chat
Codexdescribe the task, or $fnlowl-capture and the other skill names

Verify install

Try a task that should trigger one of the skills:

  • "Create a quiz widget for my pricing page."
  • "Why is this widget not converting?"
  • "Draft a three-email nurture sequence for people who finish the quiz."
  • "Add the fnlowl widget to my WordPress site."
  • "Connect Claude to fnlowl and list the tools it can use."

What's included

  • four skills that load when relevant
  • reference files and recipes for the capture and follow-up skills
  • .mcp.json, which points an agent at the hosted MCP server (OAuth sign-in on first use)

It does not ship slash commands or an MCP server of its own; the server runs at https://api.fnlowl.com/v1/mcp.

Use it

The MCP server is at https://api.fnlowl.com/v1/mcp (streamable HTTP, OAuth). .mcp.json in this package points there. Your client opens fnlowl's consent screen the first time: sign in and approve the scopes and website. Tokens are fnla_, revocable under Settings → API → Connected apps; a connector limited to one website is already project-bound, so x-fnlowl-project is ignored.

Claude.ai and ChatGPT work the same way: add the URL as a custom connector (OAuth, leave client id and secret blank).

For scripts and the CLI you can use an API key from Settings → API instead. It starts fnlk_, is shown once, and is sent as Authorization: Bearer fnlk_....

Scope a call to one project with the project argument, or set a default with the x-fnlowl-project header. list_projects returns the ids.

What it will not do

The remote MCP surface has no campaign or transactional send tool and cannot unsubscribe anyone. Publishing widgets and activating sequences are separate confirmation-required actions; the server cannot verify that conversational confirmation. High-risk Composio connection/action tools are withheld when that optional integration is configured. See references/approval-model.md.

Develop

node scripts/check-skills.mjs

Markdown and JSON, no dependencies — Node 18 or later. The one rule is describe only what is built, and a limitation goes in references/known-gaps.md rather than being left out.

The package also includes Codex, Claude, Cursor, and agent-marketplace plugin manifests.
