Access, auth, and limits
Ontraport's MCP server lives at mcp.ontraport.com and is described as a streamable HTTP MCP server. The support docs do not spell out the exact auth handshake, so confirm the token setup in your Ontraport account before wiring it up.
It exposes four capability groups: CRUD across contacts, companies, deals, and custom objects; query tools for discovery, engagement, and account-wide reporting; management tools for tags, automation enrollment, relationships, and tasks; and commerce tools for invoicing, payments, subscriptions, and revenue. The key constraint is that an agent works with a bounded set of records at a time, so plan for segments, not whole-database operations.
Where it works and what to build
Supported clients are Claude Desktop, ChatGPT, and Cursor, plus any MCP-compatible client that speaks streamable HTTP. No CLI is offered, so the MCP connection is the agent path.
Real workflows worth running: ask Claude to tag every contact who bought in the last 30 days and enroll them in a win-back automation; pull a revenue and subscription report across deals without opening the dashboard; or spin up an invoice and payment plan for a new client. Because tools cover commerce as well as CRM, an agent can take an action end to end rather than just surface data.

How to connect Ontraport MCP to Claude Desktop
Add this block to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows), then restart Claude Desktop. Cursor and Codex use a similar schema.

Does Ontraport MCP cost extra?
Ontraport ships an official MCP server that uses your existing subscription credentials.
- No separate MCP licence to buy. You pay for your Ontraport plan, the MCP server queries that account.
- Whether it's gated to a specific tier wasn't extracted automatically — verify the access requirements on the MCP page or pricing docs.
Ontraport also publishes a REST API
Ontraport publishes an API, but per-tier gating wasn't extracted automatically.
What you can do with Ontraport from an AI agent
Three shapes of agent workflow. Pick the row that matches how you actually use Claude / Cursor / Codex day to day.
Skip the dashboard, ask Claude
- "What deals stalled this week?" answered in seconds
- Quick one-off questions without leaving the editor
- Pipe Ontraport data into your personal notes / docs without writing a script
Run client analysis at agent speed
- Hand the MCP server to your team — every consultant can ask Claude about any client's Ontraport account
- Multi-account workflows without context-switching the Ontraport UI
- Reports you'd normally spend hours on, done before standup
Production agent workflows
- Embed in your internal Codex / Cursor agents that triage Ontraport data daily
- Combine with other MCP servers in a multi-step agent chain
- Constrain agents to read-only roles to keep production Ontraport safe
Limits and gotchas
- Official MCP server — published by Ontraport themselves, so it should track product changes.
- Fallback: the REST API works for any flow the MCP server doesn't cover.
- Rate limits: MCP calls count against your underlying Ontraport API quota. Burst usage from a curious agent can drain a daily allowance fast.
Agent-readiness verdict
Ontraport runs a production MCP server at mcp.ontraport.com over streamable HTTP, authenticated with OAuth against app.ontraport.com under a single mcp:tools scope, and the tool coverage spans CRM, automation and commerce. The bounded-record constraint is the real limit: it is built for targeted actions on segments, not for sweeping the whole database. The single coarse scope is worth knowing too, since it does not let you grant read without also granting write.
