Read appointments, professionals and rooms; book, update and cancel visits in ByDoctor. Hosted by usefulapi: connect it to Claude, ChatGPT, Cursor or any MCP client.
Turn on the ByDoctor connector, then ask in plain words. The AI picks the tools.
For clinics that run in-person visits and their agenda in ByDoctor.
List the clinic's appointments in a date range, filtered by status, professional or room. Open one to read its times and type.
List the appointments changed since a given time, oldest update first. Use the cursor links to read the next page.
List the active rooms, professionals and appointment types of the clinic. Use their ids when you book or move an appointment.
Book an in-person appointment with a professional and an appointment type, for a patient already in the clinic. Teleconsults are not created by the API.
Changes dataChange the start time, professional, room or note of an appointment, or cancel it. A confirmed appointment must go back to scheduled first.
Changes dataThe login page asks for your ByDoctor API key.
Create it in ByDoctor → Minha Clínica → API e Webhooks. Choose Somente leitura for read-only access, or Acesso total to allow bookings and patient changes. The key is shown once. Keys created before patients existed have no patient access: create a new key. Health data is involved: keep the key private.
Team and Enterprise: an Owner adds the connector for the organization first.
No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"bydoctor": {
"url": "https://bydoctor.usefulapi.io/mcp"
}
}
} Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"bydoctor": {
"type": "http",
"url": "https://bydoctor.usefulapi.io/mcp"
}
}
} Run these commands. The second one opens the login page:
Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.
Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your ByDoctor API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper user | $9/mo · $90/yr | 10,000 tool calls / month |
| Pro+per user | $39/mo · $390/yr | 100,000 tool calls / month |
Each paid plan covers this ByDoctor server only. Ask your AI to run bydoctor_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with bydoctor_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with bydoctor_upgrade before then undoes the cancel. Or write to [email protected].

No. usefulapi is an independent service. It is not affiliated with or endorsed by ByDoctor. The server calls the ByDoctor API with your own ByDoctor access, so it sees only the data that your account can see.
Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.
The login page asks for your ByDoctor API key. See Before you connect for where to find it.
No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your ByDoctor API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the ByDoctor API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in ByDoctor.
Yes, if you approve it. 5 of the 15 ByDoctor tools can create or change data. The other 10 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this ByDoctor server only. Cancel any time: your paid plan then runs to the end of the paid period. Run bydoctor_usage_status to see how many calls you used.
Ask the AI to run bydoctor_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run bydoctor_cancel_subscription. Your paid plan continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with bydoctor_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.
Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.
This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
