Check leads with Precleared before your agent adds them to La Growth Machine

If your AI agent runs La Growth Machine (LGM) through LGM's MCP server, connect Precleared's MCP server next to it. Your agent checks each address first and adds only cleared leads to your audiences and campaigns.

What you need

  • A Precleared key. Every new key starts with 14 days at 100 checks a day, then your own 100 a day over MCP, no card needed. Get a free key.
  • LGM's MCP server. It signs in with OAuth; clients that can't do OAuth can send your LGM API key as a Bearer token. LGM's pages differ on which plans include it, so check yours.

1. Connect both servers

In Claude Code:

claude mcp add --transport http precleared "https://precleared.dev/mcp?src=guide-la-growth-machine" --header "Authorization: Bearer pc_live_..."
claude mcp add --transport http --scope user LaGrowthMachine https://mcp.lagrowthmachine.com

In Claude.ai or the Claude desktop app, add https://precleared.dev/mcp?src=guide-la-growth-machine and https://mcp.lagrowthmachine.com under Settings, Connectors, Add custom connector. See LGM's MCP guide.

2. Give your agent the rule

Paste this into your agent's instructions, a project's instructions or a skill:

Before adding a new lead to a La Growth Machine audience or campaign, call Precleared's contact_check once for its email address. Send address_source (where you got the address) and sender_country, plus company_name and pitch when you know them.
- ok_to_email: add the lead and keep the receipt id with it.
- consent_needed or blocked: don't add the lead. Note the next_step.
- unknown: don't add the lead yet. Supply the missing fact (recipient_country, default_recipient_country if all your prospects are in one country, or company_number), then check again.
Every email must meet footer_text: usually who you are, a postal address and a way to opt out.

What happens to each lead

VerdictWhat your agent does in LGM
ok_to_emailAdds the lead, keeping the receipt id
consent_needed or blockedLeaves the lead out
unknownHolds the lead until the missing fact is supplied, then checks again

Good to know

  • LGM says its MCP server has about 50 tools but hasn't published their names, so the rule describes the action and your agent picks the tool.
  • If a lead that fails is already in LGM, set its status to UNSUBSCRIBED through LGM's API (POST https://apiv2.lagrowthmachine.com/flow/leads/status). That ends its campaign, for that lead only.
  • Settings come from LGM's docs as of 30 October 2026. If its tools change, your agent sees the new names in the server's tool list.
  • The ?src=guide-la-growth-machine tag on Precleared's address only tells us which guide you used. It doesn't change your allowance or your results.

Every check has a signed receipt. Open precleared.dev/r/ followed by its id to show a client why an email went out.
