MCP connector cost and scope calculator
Your estimate
Answer the seven questions to see your scope, timeline and price band.
Estimate only. Not a quote or offer. The Audit produces a fixed price.
What drives the price
Platforms
A Connector Launch Sprint covers one platform plus the Official MCP Registry for $9,500, two platforms for $11,000, and Claude, ChatGPT and Cursor together for $12,500. The Registry listing is always included. Each platform adds its own submission package and review, but the connector underneath is the same remote MCP server.
Tools
We map your API to 8 to 20 tools shaped around real jobs, not one tool per endpoint. More than 20 tools, or an interactive UI inside chat (MCP Apps), is scoped in the Audit and starts at $15,000.
Auth
If you run OAuth 2.x yourself, we build on it. If your API only takes API keys, we add an OAuth 2.1 authorization server: $1,500 and about one extra week. Not sure? The Audit confirms the approach before the price is fixed.
OpenAPI spec
With an OpenAPI spec we map your API directly. Without one, mapping it first adds $1,000.
An existing server
If you already run your own MCP server and need no new platforms, the Connector Upgrade ($2,500 to $5,000, 1 to 2 weeks) moves it to the 2026-07-28 spec, adds Client ID Metadata Documents, fixes annotations and responds to a rejection. A community-built server counts as no server of your own.
Security reviews
If enterprise buyers ask for a security review, the Connector Trust Pack adds $1,500 for up to 14 tools, or $3,000 above that: a threat model, a scope matrix and a reviewer-ready security statement.
Timeline
A Sprint takes 3 weeks of build for one or two platforms, 4 for all three; an OAuth server adds about one week. Platform review time is set by Anthropic, OpenAI and Cursor and is not included.
Founding price
Our first five Launch Sprints are $7,500 instead of $9,500, in exchange for a public case study with your approval. The founding price covers the auth and OpenAPI add-ons above.
After launch
Connector Care keeps the connector monitored and evaluated each month: Essential $750, Growth $1,250, Pro $2,000 per month, with a 3-month minimum. The estimate suggests a tier from your tool count and scope.
Why an estimate, not a quote
The band comes from our published prices, but it is not final. The $750 Agent Distribution Audit maps your API, auth and competitors in 5 business days and turns the band into a fixed price, credited in full to your build if you proceed within 30 days.
