Why Pathbound

PostHog tells you what happened. Pathbound tells you to whom—across everything.

A direct PostHog connector shows your agent product events. Pathbound shows your agent the customer—PostHog events stitched together with your CRM, support, email, and website events—through one unified profile served over the Model Context Protocol.

Product behavior in context

Feature usage and activation events land on the same timeline as deal stage, support tickets, and emails. Your agent sees what they did in the product next to everything else—not in a separate analytics tab.

Identity-resolved

A PostHog person (distinct_id, email) resolves to the same unified contact you have in your CRM, Gmail, and website events. A direct connector only knows PostHog’s own IDs.

Dashboards stay in PostHog

PostHog powers your product team’s dashboards; Pathbound puts the same events on the contact profile your AI agent (and your AE or CSM) reads before the next action. Different consumers, same source.

Built for LLMs

Token-efficient response shapes and server-side aggregation mean agents get usage summaries and counts, not a raw event firehose that blows the context window.

FAQ

Common questions.

Is this an official PostHog MCP server?

Pathbound is an independent platform. We connect to PostHog via its API using a key you generate, and expose your data through one Model Context Protocol server alongside your other sources. Not affiliated with PostHog.

Does Pathbound write to PostHog?

No. The PostHog integration is read-only—it pulls persons and product events into the unified profile and never writes anything back to PostHog.

How is this different from PostHog’s own dashboards or API?

PostHog is product analytics for your team’s dashboards and queries. Pathbound puts the same events on the per-contact profile your AI agent, AE, or CSM reads before the next action—identity-resolved with your CRM, email, and support. Different consumers, same source.

How are PostHog events matched to a contact?

By identity resolution on distinct_id and email. A person’s product behavior lands on the same unified profile as their CRM record, conversations, and web activity.

Which MCP clients does this work with?

Claude.ai, Claude Desktop, Claude Code, ChatGPT (with custom connectors), Cursor, Cline, Continue—any client that supports the Model Context Protocol with OAuth.

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, Intercom, Gmail?

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