API to Agents charges a one-time setup fee from $499 to design, build, and launch the MCP server for your API, then a monthly managed hosting plan of $29.99 (Starter) or $99.99 (Growth) that begins only when the integration is live. The setup fee is calculated by versioned pricing rules (currently 2026-09-13.v2) from the scope your free audit proposes, is itemized, and is valid for 14 days. Quotes above $3,999 and Enterprise requirements are scoped with our team.
Setup line items
The base scope covers one upstream API, up to 3 read tools, API-key authentication, and one revision round. Everything else is added only when your audit evidences it, at the prices below. The raw total is rounded up to the next $50 step minus $1, with a minimum of $499.
| Line item | Price | When it applies |
|---|---|---|
| Setup base | $499 | Always. One upstream API, up to 3 read tools, API-key authentication, one revision round. |
| Additional read tool | $60 each | Each read tool beyond the 3 included. |
| Write tool | $120 each | Each tool that creates or changes data. If you declare write access before a write tool is evidenced, one is priced now and confirmed in review. |
| High-consequence safeguards | $200 each | Each guarded tool whose action needs an explicit confirmation step, such as placing an order or changing billing. |
| OAuth / OIDC authentication | $300 | Your API authenticates users with OAuth or OpenID Connect. |
| Classified custom authentication | $600 | A custom authentication scheme that is neither API key nor OAuth/OIDC. |
| Missing or partial documentation | $300 | Documentation is absent, or only available as HTML or plain text. We document the API with you. |
| Second upstream system | $300 | The integration spans two upstream systems. More than two is scoped with the team. |
| Optional MCP App UI | $250 | You request an interactive MCP App surface in addition to tools. |
| Supervised production testing | $150 | No sandbox exists and testing must happen in production under supervision. |
Managed hosting plans
Hosting covers the endpoint at your subdomain, monitoring, maintenance, and updates as MCP clients change. The plan you select is recorded with your quote and is not billed before your integration goes live.
| Plan | Price | For |
|---|---|---|
| Starter | $29.99 per month | A focused first integration: managed hosting, monitoring, and maintenance for your scoped MCP tools. |
| Growth | $99.99 per month | A larger scope. Plan details are confirmed with your integration scope. |
| Enterprise | Scoped together | Self-hosting, private cloud, or complex multi-system integrations. |
Worked examples
- A documented REST API, API-key auth, three read tools: $499.
- The same API with two write tools and one guarded tool: raw $939, rounded to $949.
- An OAuth-protected GraphQL API with four read tools and one write tool: raw $979, rounded to $999.
What the quote promises
The quote is fixed for the declared API, authentication method, testing plan, and listed tools. If the paid technical review finds a material undocumented difference, we offer an adjusted scope or a full refund before implementation begins. Payment is through Stripe Checkout; a quote is marked paid only after a signature-verified webhook, never from a browser redirect.
Prices are quoted in USD and exclude any applicable taxes. The full conditions are in the terms of service.
Frequently asked questions
How much does an MCP server setup cost?
From $499 for one API with up to 3 read tools and API-key authentication. Write tools, guarded actions, OAuth, and other scope items are added by the published rules, and the exact figure comes from your free audit.
Who decides the price?
Versioned application code. The AI analysis proposes tools and finds risks; it never calculates or changes a price.
When does hosting billing start?
Only when your integration is live. The plan you select is recorded with your quote but nothing recurring is charged before launch.
How long is a quote valid?
14 days from the audit. After that, run a new audit for a fresh quote.
Is there a maximum automatic quote?
Yes, $3,999. Larger scopes, more than two upstream systems, private hosting, and Enterprise plans are scoped with our team.
What if the review finds something the audit missed?
We offer an adjusted scope or a full refund before implementation begins. The fixed quote carries that promise.
