README from the maker

Open the README

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

@leadsync/mcp

The MCP server for the LeadSync API. It lets Claude and other MCP clients set up and troubleshoot LeadSync lead delivery: connect Meta lead forms to destinations, map fields, add autoresponders, send test leads and check what happened to a lead.

Most people install it with the installer, which also adds the LeadSync skills:

npx @leadsync/skills --claude    # or --cursor, --codex

npx @leadsync/skills login

To run it by hand in any MCP client, use the command npx -y @leadsync/mcp. The full guide, the tools list and the safety rules are in the repository README.

Settings

The server reads each setting from the environment first, then from ~/.leadsync/.env (one KEY=value per line, written by npx @leadsync/skills login).

Variable	What it does
`LEADSYNC_API_KEY`	Required. Your API key, from Account, Settings, API keys in LeadSync. Never written to logs or tool output.
`LEADSYNC_API_BASE`	Optional. Defaults to `https://leadsync.me`.
`LEADSYNC_ACCOUNT`	Optional. LeadSync staff only.

Licence: MIT.
