Hosted MCP servers for real APIs

Build hosted MCP serversfor real APIs, from the UIor your AI agent

Turn REST and GraphQL APIs from public services, SaaS platforms, and internal business systems into hosted remote HTTP MCP servers with OAuth, API key, Bearer token, Basic Auth, workflow tools, encrypted credentials, and JMESPath output mapping.

Two production-ready ways to create MCP servers

Use the dashboard when you want hands-on control. Use Agent Builder when you want Codex, Cursor, Claude Code, or another IDE agent to create and iterate for you.

Visual Builder

A guided dashboard for teams that want to review auth, tools, output mapping, test results, and deployment settings before publishing.

Configure auth, base URL, and MCP access
Define API tools, workflow tools, and output mapping
Test requests before deployment
Deploy a production MCP endpoint

AI Agent Builder

Connect the API To MCP manager server once, then ask your coding agent to create, update, test, deploy, and inspect servers from chat.

Connect https://mcp.apitomcp.app/ to your agent
Create a scoped manager token
Describe the API you want to convert
Let the agent create, update, test, and deploy it

Prompt example

Create an MCP server for our internal support platform using OAuth Authorization Code so each employee connects their own account. Add ticket lookup and workflow tools, test them, then return the MCP URL.

What you can build

Start from your own business platform, internal endpoints, authenticated SaaS APIs, or public data APIs. API To MCP turns them into hosted tools your agents can call.

Business Platforms

Expose your company CRM, ERP, HR, finance, support, or operations platform to employees through controlled MCP tools.

Internal CRMERPHRISFinance Ops

Marketing and SEO

Connect ad, analytics, and search APIs for reporting, inspection, content, and optimization workflows.

Meta AdsGoogle AdsGoogle AnalyticsSearch Console

Commerce and Billing

Build MCP tools around billing, catalog, product, and order APIs.

PayPalShopifyWooCommerce

Developer

Give coding agents controlled access to repositories, deploys, issues, and observability data.

GitHubGitLabVercelSentry

Public Data

Publish no-auth MCP servers for open data APIs that anyone can use by URL.

Content

Turn content systems into MCP tools for publishing, lookup, and editorial workflows.

Authentication for real-world APIs

API To MCP separates upstream API authentication from MCP server access, so teams can support REST and GraphQL APIs, private systems, and employee-authorized platforms.

Credential security

Stored API keys, Bearer tokens, Basic passwords, OAuth client secrets, access tokens, and refresh tokens are encrypted at rest and masked in the owner UI.

Encrypted at rest for stored credentials and OAuth tokens

Masked in edit screens unless the owner replaces the value

Snapshots never include live secrets or active connection tokens

No Authentication

For public APIs and open-data endpoints that do not require credentials.

API Key

Send keys in headers or query parameters for services that use token-style access.

Bearer Token

Store a token securely, or forward the Bearer token supplied by the connected agent.

Basic Auth

Use username and password authentication for legacy or internal APIs.

OAuth 2.0

Use Client Credentials for service-to-service access, or Authorization Code so each user connects their own account.

Custom OAuth & Presets

Start with Shopee or TikTok Shop presets, or define your own authentication flow, token mapping, and request signing through the dashboard or an AI agent.

Learn about presets

MCP access modes

Choose how AI clients connect to the MCP server itself. This is separate from the credential used to call the upstream API.

Open MCP servers for public or agent-supplied upstream credentials

OAuth/Bearer Token for clients that authenticate the MCP connection

Client Token for an extra API To MCP access layer when needed

Everything you need to convert APIs to MCP

Build, authenticate, compose, deploy, and share production MCP servers without writing custom MCP runtime code.

Visual MCP Builder

Configure REST or GraphQL integrations, tools, schemas, response mapping, tests, and deployment from a guided dashboard.

Manager MCP for AI Agents

Connect the API To MCP manager server and let AI agents create, update, test, deploy, and inspect MCP servers from chat.

OAuth Client Credentials

Use server-to-server OAuth for APIs such as billing, commerce, internal services, and GraphQL backends that issue machine tokens.

Per-user OAuth Authorization Code

Let each employee or MCP end user connect their own upstream business-platform account through OAuth.

Workflow Tools

Compose multiple API tool calls into one MCP tool for multi-step lookup, enrichment, and action flows.

Response Mapping with JMESPath

Shape nested upstream API responses into clean JSON outputs that are easier for agents to consume.

Templates and Public Directory

Publish live MCP servers to the directory or share reusable snapshots that copy tools and configuration without secrets.

Hosted Streamable HTTP Runtime

Deploy remote HTTP MCP endpoints with Open or Authenticated access, SSL, usage tracking, and hosted runtime management.

How it works

Build MCP servers through the visual UI or directly from the AI agent where you already work.

Best when you want full control in the dashboard.

Configure API

Create tools

Run tests

Deploy server

Lane B: Agent Builder

Best when you want your IDE agent to do the setup.

Connect once

https://mcp.apitomcp.app/

Ask your agent to create, test, and deploy the MCP server.

Configure API access

Enter your REST or GraphQL API base URL and choose the upstream auth model: no auth, API key, Bearer token, Basic Auth, OAuth Client Credentials, or OAuth Authorization Code.

Integration Guide

Your MCP server is now live! Use the configuration below to connect it to AI clients:

Remote MCP Configuration

VS Code / Cursor

{

"servers": {

"your-site-mcp": {

"type": "http",

"url": "https://your-site-mcp-w8jg832k998m.apitomcp.app/"

}

Setup Instructions

For remote HTTP MCP clients:

Copy your server URL
Add it as a remote HTTP MCP server
Add a Bearer token only when the server access policy requires one
Enable the server in your AI agent or IDE
Your tools are available to the agent immediately

Your MCP Server URL:

https://your-site-mcp-w8jg832k998m.apitomcp.app/

This URL will be available after you deploy your MCP server.
