01

Sign up for Pathbound

Create an account at pathbound.ai. Free during public alpha.
02

Connect HubSpot

In the dashboard, go to Integrations → HubSpot → Connect. OAuth via HubSpot’s official OAuth API in one click; sync runs every minute and pulls contacts, companies, lifecycle stage, lead status, and custom properties.

Run a test prompt

Ask the agent: “How many contacts do I have in HubSpot?” The agent calls list_contacts via MCP and returns the count.

Why Pathbound

Your customer doesn’t live only in HubSpot.

A direct HubSpot MCP shows your agent HubSpot. Pathbound shows your agent the customer—across HubSpot, Gmail, Intercom, your website events, Apollo, Calendly, and the rest of your stack—through one unified profile served over the Model Context Protocol.

Beyond HubSpot

Gmail threads, Intercom conversations, website page views, Apollo enrichment, Calendly meetings—all stitched onto one timeline per contact. Your agent stops asking “who is this?” on every other tool.

Identity-resolved

Same person as [email protected] in HubSpot, [email protected] in Gmail, “Jane R.” in Intercom—Pathbound resolves to one entity. A direct connector only knows its own IDs.

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.

Governed writes

Your agent can write, too—notes, lifecycle changes, and profile updates land on the unified contact, gated per-tool by an admin. Write-back to HubSpot, versioning, and rollback are rolling out—the controls SOC 2 and GDPR reviewers expect.

FAQ

Common questions.

Is this an official HubSpot MCP server?

Pathbound is an independent platform. We connect to HubSpot via HubSpot’s official OAuth API and expose your data through one Model Context Protocol server alongside your other sources. Not affiliated with HubSpot.

How is this different from the HubSpot REST API?

REST is for backends and scheduled jobs. MCP is for AI agents—it’s the protocol Claude, ChatGPT, and Cursor speak. Pathbound’s MCP also unifies HubSpot with Gmail, Intercom, your website events, and other sources into one profile per contact, so the agent doesn’t glue six APIs together itself.

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.

Can the agent write to HubSpot, or just read?

Both. Pathbound exposes 16 read tools (list, get, timeline, conversations, aggregate, batch) and 10 write tools (create / update contacts and companies, create / update / delete notes). Writes land on the unified profile every connected agent reads; write-back into HubSpot itself is rolling out.

How does authentication work?

OAuth 2.0 end to end. The MCP client opens Pathbound’s login; you log in once and the agent gets scoped access tied to your user. Revoke anytime from Settings → Connected Apps.

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 Pipedrive, Salesforce, Apollo, Intercom?

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