To connect an API to Claude, you publish it as a remote MCP (Model Context Protocol) server: an HTTPS endpoint that exposes tools Claude can call. Claude supports remote MCP servers as custom connectors, added by URL, with OAuth where the server requires it. Once connected, a user asks Claude for an outcome in plain language and Claude calls your tools to search, read, or act on your service. API to Agents designs, builds, and hosts that server under your own subdomain for a fixed price, starting from a free audit.
Where the integration shows up
MCP is Claude's native way to reach external tools, so one server covers the products your customers already use:
- Claude on the web and the desktop apps, through custom connectors.
- Claude Code and other developer tools that accept MCP server configuration.
- Any other MCP client, including ChatGPT, with the same server.
What your customers can do in Claude
- Read tools: search your catalogue, look up an account, retrieve a record or document. No confirmation needed.
- Write tools: create a request, update a record, add an item. Designed with retry contracts so a repeated call never duplicates work.
- Guarded tools: place an order, cancel a booking, change billing. Claude must obtain an explicit confirmation before execution.
Authentication and account mapping
A remote MCP server for a multi-customer service has to know whose data it is acting on. The base setup uses API-key authentication; OAuth or OIDC is a priced option. We separate authorizing the connection from accessing records, so that connecting Claude never grants access beyond the user's own account, and read tools check permissions on every call.
Getting there
Start with the free audit to see the tools Claude would get and the fixed setup price. After payment, a human-validated roadmap is published within 72 hours, and we build and host the server as a managed MCP server at mcp.yourcompany.com. It serves ChatGPT and other MCP clients from the same endpoint.
Frequently asked questions
Does Claude support remote MCP servers?
Yes. Claude supports remote MCP servers as custom connectors added by URL, in its web and desktop products and in Claude Code. Availability of custom connectors depends on the plan and organization settings.
Does the same server work for ChatGPT and Claude?
Yes. MCP is client-neutral. One hosted server serves Claude, ChatGPT, and any other MCP client.
How does Claude know which customer it is acting for?
Through the authentication method your integration supports. With API keys, each key maps to an account; with OAuth, the user authorizes the connection and every tool call carries that identity. Read tools check permissions on each call.
Can Claude take actions, not just read?
Only through write and guarded tools you choose to expose. Guarded tools require an explicit confirmation step before execution.
What does it cost?
A fixed setup fee quoted after the free audit, then a monthly managed hosting plan that starts only when the integration is live. The pricing page lists every line item.
