La Growth Machine MCP server

Connect La Growth Machine to Claude, ChatGPT, Cursor, and any MCP-compatible AI agent. LGM leads, audiences, and campaign membership — joined to the same contact as your CRM, inbox, and website activity.

Why Pathbound

LGM tells you what you sent. Pathbound tells you who it reached.

A direct LGM connector shows your agent the sequence. Pathbound shows your agent the customer — LGM lead alongside the same person in HubSpot, the same email thread in Gmail, the same pageviews in your tracker — through one unified profile served over the Model Context Protocol.

One identity across channels

LGM identifies leads by pro email, personal email, LinkedIn URL, and phone. Pathbound resolves any of those to the same Contact you already have in HubSpot, Gmail, your tracker, and Apollo. Stop reconciling four IDs by hand.

Outreach in context

Audience membership and campaign status sit on the same timeline as their pricing-page visits, replies, and meetings. The agent sees what you sent, what they did, and what the CRM thinks — all in one read.

Built for LLMs

Token-efficient response shapes (count_only, fields=summary), server-side aggregation, batch tools. Agents get the answer, not raw JSON dumps. Stays inside the context window.

Pull, not stream

LGM data is pulled on a 60-minute schedule into the unified profile. No webhooks to configure, no per-tenant URLs to paste back into LGM. Connect once with an API key and it shows up.

FAQ

Common questions.

Is this an official La Growth Machine MCP server?

Pathbound is an independent platform. We connect to La Growth Machine via their REST API using an API key you generate in LGM, and expose your data through one Model Context Protocol server alongside your other sources. Not affiliated with La Growth Machine.

Does Pathbound write back to La Growth Machine?

No. This integration is pull-only — LGM data is read into the unified profile on a 60-minute schedule. The agent reads, you act in LGM. Write-back is on the roadmap.

Which LGM data does Pathbound sync?

Audiences, leads (firstName, lastName, proEmail, persoEmail, phone, linkedinUrl, companyName, companyDomain, jobTitle, status, custom variables), and campaign metadata. Stale leads — those removed from an audience between syncs — are reflected on the next pull.

How does Pathbound match an LGM lead to my existing contacts?

Identity resolution: pro email → personal email → LinkedIn URL → phone. If the same person already exists in HubSpot, Gmail, or your tracker, the LGM lead joins that profile instead of creating a duplicate. Sales-Navigator-style LinkedIn URLs aren’t accepted by LGM, so Pathbound uses the canonical /in/ form.

Do I need a paid LGM plan?

LGM gates API access behind their higher tiers. Check your LGM plan or contact LGM sales if you’re not sure. Pathbound itself is free during public alpha.

Is my customer data secure?

Tenant-isolated and OAuth-scoped per user, with encryption at rest via our infrastructure provider's default configuration. GDPR-aligned; SOC 2 readiness in progress. Pathbound does not sell customer data, and we don't call AI providers on your behalf — your MCP client does, under your account and the AI provider's terms.

What about HubSpot, Pipedrive, Apollo, Gmail?

Same MCP server, same tools — just connect a different source. See the integrations directory.
