Onsite MCP

On this page

Connect your AI tools

Link Claude , ChatGPT , or other supported AI clients to your Onsite account and work with building data from the tools you already use - within your user permissions and approved scopes.

Add to Claude

Demo

See Onsite MCP connected in an AI client and used against live building data.

Recipes

Once connected, try these example workflows. Click a recipe to see the details and sample prompt.

Turn an email thread into a case with history

Paste or connect an email thread, create an Onsite case for the issue, then add comments that log each step taken in the thread. Backdate comment times so the case timeline matches when things actually happened.

Requirements

  • An active Onsite account
  • MCP is opt-in - your organisation may control which AI tools users connect and how they are used

Server details

Onsite MCP is a remote HTTP MCP server, not a local process you run on your machine.

Endpoint

https://api.onsite.fm/mcp

Remote MCP over HTTPS

Authentication

Connections use OAuth 2.1 through Onsite’s authorization server at https://auth.onsite.fm. When you add the server in your AI client, you will be prompted to sign in with Onsite and approve the requested scopes.

Connect in your AI client

ChatGPT

Onsite MCP can be added in ChatGPT as a custom plugin (remote MCP).

  1. Go to the plugins page on the web:

    https://chatgpt.com/plugins

  2. Add a new plugin.

  3. Enter the MCP URL https://api.onsite.fm/mcp, accept the custom MCP checkbox, then create the plugin.

ChatGPT New Plugin dialog configured for Onsite with Server URL https://api.onsite.fm/mcp and OAuth authentication

Example: New Plugin setup with Onsite name, Server URL, and OAuth selected.

Claude

Onsite MCP can be added in Claude as a custom connector (remote MCP). Use the button below to open Claude with the server details prefilled, then confirm and complete OAuth.

Add to Claude

Opens Claude’s custom connector dialog with https://api.onsite.fm/mcp ready to confirm.

Or add it manually

  1. Open Customize → Connectors (or Settings → Connectors in Claude Desktop).

  2. Add a custom connector / remote MCP server.

  3. Enter the server URL: https://api.onsite.fm/mcp

  4. Sign in with Onsite when prompted and approve the requested scopes.

  5. (Optional) Whitelist api.onsite.fm so Claude can access images returned by Onsite (for example building photos and case attachments). Add it under Claude’s allowed / trusted domains in settings.

Other

For other AI clients that support remote MCP over HTTPS:

1

Open your AI client’s MCP or integrations settings.

2

Add a remote MCP server (not a local command).

3

Enter the server URL:

https://api.onsite.fm/mcp

4

Complete the OAuth sign-in flow in your browser when prompted.

5

Confirm the connection is active in your client.

Using Onsite MCP

Use with care

AI clients can call MCP tools repeatedly in autonomous loops. Avoid open-ended or “keep going until done” prompts that may hammer the integration - review what your client is doing, and stop runs that are calling tools in tight loops without a clear goal.

Pricing

Onsite MCP is free at the moment. We may introduce fees during or after beta - we will give you notice before any charges apply.

We want your feedback

This is an early integration and we are actively improving it. You can share feedback through the MCP itself - ask your AI client to submit product feedback to Onsite when something works well or does not.

Disconnect or revoke access

You can disconnect at any time by removing or disabling the Onsite MCP server in your AI client’s settings. To revoke access on the Onsite side, contact Onsite support - in-app revoke is underway.

Support

If you have trouble connecting, contact support@onsite.fm.
