Connect your AI to Asendar™

Claude

Claude supports custom connectors on the Free, Pro, Max, Team and Enterprise plans. A Free account can add one custom connector. You add it on claude.ai or in Claude Desktop, and it then works in Claude on the web, on the desktop and in the mobile apps.

Free, Pro and Max

1. Open Claude and go to Customize > Connectors.
2. Click Add custom connector (on some accounts, click Add first).
3. Name it Asendar and paste the server link, https://asendar.app/api/mcp. Click Continue.
4. If Claude asks how to sign in, choose Sign in now under Authentication and Register automatically under OAuth client. If your dialog shows Advanced settings instead, leave them empty. Click Add.
5. When Claude sends you to asendar.app, sign in with your Asendar account. If it does not, click Connect next to Asendar in Customize > Connectors.
6. In a chat, click the + button, select Connectors and make sure Asendar is turned on.
7. Try: "Using Asendar, what clinics are on the network?"

Team and Enterprise

1. An Owner adds it once for the organization: Organization settings > Connectors, then Add, Custom, and Web if Claude asks for a type. Paste the server link and click Add. Choose Register automatically if Claude asks about the OAuth client.
2. Each member then goes to Customize > Connectors, finds Asendar (labelled Custom), clicks Connect and signs in with their own Asendar account.

ChatGPT

Add Asendar (admin, owner or permitted member)

1. On chatgpt.com, open Plugins.
2. Select the + button, then Add custom MCP server.
3. Name it Asendar. Under Connection, paste the server link, https://asendar.app/api/mcp.
4. For authentication, choose OAuth. There is no client ID or secret to enter: ChatGPT registers itself with Asendar.
5. Read the risk warning, tick I understand and want to continue, then select Create as a plugin.
6. When ChatGPT sends you to asendar.app, sign in with your Asendar account.
7. To share it with your workspace, an admin or owner publishes it after testing.

Use it

1. The first time, open Settings > Plugins, select Asendar and select Connect if asked. Sign in with your own Asendar account.
2. In a new chat, type @ and select Asendar. ChatGPT may ask you to confirm before it uses an Asendar tool.

Gemini

1. On a computer, go to gemini.google.com.
2. At the bottom, click Settings, then Connected Apps. If you do not see it, click Personal Intelligence, then Connected Apps.
3. Under Custom apps, use the Add a custom app link to get started field, or click Add a custom app.
4. Paste the server link, https://asendar.app/api/mcp. Leave Advanced features as they are: Asendar lets Gemini register itself, so there are no credentials to enter.
5. Click Next and follow the steps. When Gemini sends you to asendar.app, sign in with your Asendar account.
6. In a chat, type @ and select Asendar, so Gemini uses it for that question.

Grok

1. Go to grok.com/connectors.
2. Click New Connector, then Custom.
3. Paste the server link, https://asendar.app/api/mcp.
4. Complete the sign-in: when Grok sends you to asendar.app, sign in with your Asendar account.
5. Try: "Using Asendar, explain the ketamine program."

Grok Business and Enterprise

A team admin signs in to console.x.ai, selects the team and goes to Grok Business > Connectors, clicks + Add Connector, selects Other and pastes the server link. Team members then connect their own Asendar accounts on grok.com/connectors.

Other apps

Any app that can connect to a remote MCP server over Streamable HTTP, with OAuth sign-in, can use Asendar. Give it the server link and nothing else. The first time it connects, it opens asendar.app in your browser so you can sign in.

Claude Code

From a terminal:

claude mcp add --transport http asendar https://asendar.app/api/mcp

Then, in Claude Code, run /mcp, choose asendar and sign in in your browser. In a project's .mcp.json, the entry looks like this:

{
  "mcpServers": {
    "asendar": {
      "type": "http",
      "url": "https://asendar.app/api/mcp"
    }
  }
}

Cursor

Add this to ~/.cursor/mcp.json (for every project) or .cursor/mcp.json (for one project), save and restart Cursor. Then open Customize, find asendar and follow its sign-in prompt.

{
  "mcpServers": {
    "asendar": {
      "url": "https://asendar.app/api/mcp"
    }
  }
}

VS Code

Run MCP: Add Server from the Command Palette, choose HTTP, paste the server link and name it asendar. Or add it to .vscode/mcp.json:

{
  "servers": {
    "asendar": {
      "type": "http",
      "url": "https://asendar.app/api/mcp"
    }
  }
}

VS Code opens your browser to sign in the first time it connects.

Gemini CLI

On June 18, 2026, Google replaced Gemini CLI with Antigravity CLI for people on its unpaid tier and on Google One. If you still use Gemini CLI, for example with a paid Gemini API key, add Asendar from a terminal:

gemini mcp add --transport http --scope user asendar https://asendar.app/api/mcp

or put this in ~/.gemini/settings.json:

{
  "mcpServers": {
    "asendar": {
      "httpUrl": "https://asendar.app/api/mcp"
    }
  }
}

Then run /mcp auth asendar in Gemini CLI to sign in.

Any other app

Look for "remote MCP server", "custom connector" or "MCP server URL" in the app's settings. Paste the server link, choose OAuth (or sign-in) if it asks, and leave any client ID and secret empty. If the app only offers a key or token, or only runs servers on your own computer, it cannot connect to Asendar.
