Lead Leak Check MCP Server

lead-leak-check (MCP server)

Find where inbound leads are silently dropped between the first touch and the first human reply.

Your Zapier, Make or n8n runs say Success. The lead still never hears back: nobody owned the reply, a filter stopped on an empty field, the workflow was switched off for a day, or an AI draft sat unsent. lead-leak-check turns a description of your lead pipeline into a ranked list of those risks, each with a concrete fix.

Tools

Resource: leakcheck://rules lists all 15 rules with their explanation and fix.

Anything you don't describe is reported as verify, never as safe. No network calls, no data leaves your machine.

Install

git clone https://github.com/paopao-studio-ai/lead-leak-check-mcp && cd lead-leak-check-mcp
pip install .            # Python 3.10+, works with mcp 1.x and 2.x

One-click bundle (MCPB)

Example output (top of the report for the config above):

# Lead leak risk: Typeform -> Google Sheets -> Slack #sales
Risk score: **100/100** (12 findings)
## 1. [HIGH] Nobody owns the first reply
- Why it leaks: Leads posted to a shared sheet or channel are seen by everyone and answered by no one.
- Fix: Assign an owner per lead (round robin or fixed) at the moment it is created, and name them in the notification.

Fix the #1 finding for free

The most common high-severity finding is "no alert when a lead goes unanswered". The free n8n missed-lead heartbeat template (https://github.com/paopao-studio-ai/n8n-missed-lead-heartbeat) checks your sheet or CRM every 5 minutes and pings Slack, Discord or any webhook when a lead waits past your SLA.
