Connecting ChatGPT

Add Clment as a custom MCP plugin in ChatGPT — Settings → Plugins, add a custom plugin, authorize once, then chat.

Updated 22 Sept 2026

ChatGPT can drive Clment’s full review surface through the same MCP (Model Context Protocol) server that powers the Claude connector. Add Clment as a custom plugin, authorize once, then chat.

Before you start

You’ll need:

  • A paid ChatGPT plan — Plus, Pro, Business, Enterprise, or Edu. Custom MCP plugins aren’t available on the Free tier.
  • The ChatGPT web app (chatgpt.com) or desktop app, where custom plugins are managed.
  • A Clment account with at least one organization. The plugin is scoped to whichever org you authorize against, so sign in to the right one first.

ChatGPT only connects to remote MCP servers reachable over HTTPS — which Clment is. It can’t run local command-line MCP servers.

1. Open the New Plugin form

  1. Open Settings → Plugins.
  2. Click Browse plugins.
  3. Click the + (add) button to add a custom plugin. The New Plugin form opens.

2. Enter Clment’s details

In the New Plugin form:

  1. Name — e.g. Clment (the field shows Custom Tool as a placeholder). The Icon and Description are optional.
  2. Connection — leave the toggle on Server URL (not Tunnel) and paste Clment’s MCP endpoint for your org’s data region: https://api-<your-region>.clment.com/v1/mcp (e.g. https://api-uk.clment.com/v1/mcp). The exact URL is shown under Settings → Connect AI Agent in the Clment web app. (ChatGPT’s placeholder shows an /sse example — ignore it; Clment’s path is /v1/mcp.)
  3. Authentication — choose OAuth. Clment self-registers via Dynamic Client Registration, so Advanced OAuth settings are discovered automatically once the URL is valid — you don’t need a Client ID or Secret.
  4. Tick I understand and want to continue to acknowledge OpenAI’s standard custom-MCP warning, then click Create.

3. Authorize once

When you click Create, ChatGPT opens Clment’s consent page in your browser. It shows exactly which skills the plugin is requesting — read, write, or both. Sign in to Clment if needed and click Allow.

The connection ChatGPT keeps:

  • Is scoped to one organization — add a second plugin to use another org.
  • Is attributed to you in Clment’s audit logs for any write actions.
  • Can be revoked any time under Settings → Connect AI Agent in the Clment web app.

4. Chat

In a chat, enable the Clment plugin for the conversation (from the + / tools menu). Then ask away:

  • “List my contracts expiring in the next 90 days.”
  • “Upload this URL and start a review with our standard vendor rulebook.”
  • “For REV-12, accept the AI’s recommendations and generate the redline.”

With a read + write connection, ChatGPT can also correct the details Clment extracted — the parties, the key dates and duration, or the financial terms — and every edit is logged to your name (the MCP skills catalog lists each write tool):

  • “On CLM-42, change Jordan Lee’s role to Landlord and add Acme Realty as a counterparty.”
  • “Set CLM-42’s effective date to 13 Oct 2018, expiry to 12 Oct 2020, and the duration to 2 years.”
  • “Update CLM-42’s financials to SGD 2,400 per month, payable monthly in advance.”

Uploading files

Ask ChatGPT to “upload this contract and start a review”. The most reliable route is to give it a link to the file — a Google Drive, SharePoint, or any HTTPS URL Clment can reach — which Clment fetches server-side. You can also drag the file into the Clment web app directly. (Pushing a local file’s bytes straight from the chat depends on ChatGPT’s file tooling and isn’t always available.) See Uploading contracts.

Troubleshooting

Can’t add a custom plugin — you’re likely on the Free plan, or not in the web/desktop app. Custom MCP plugins need a paid plan (Plus, Pro, Business, Enterprise, or Edu) on chatgpt.com.

Connection fails — confirm the URL ends in /v1/mcp (not the /sse example in the placeholder), and that your region’s API answers in a browser (https://api-au.clment.com/health — your region’s host — returns JSON).

Plugin loses access after a while — re-authorize from Settings → Plugins. If it keeps dropping, revoke the plugin in Clment (Settings → Connect AI Agent) and add it again.

“Unknown or revoked client” on the consent screen, or switching to a different Clment account, org, or region — ChatGPT reuses the client registration it first created, so it presents the same identity even after you remove the connection. If that identity belongs to a different Clment environment or region (or was revoked), the consent screen can’t accept it. Reconnect cleanly:

  1. In ChatGPT, open Settings → Plugins and select the Clment plugin.
  2. Disconnect it first, then remove/delete the plugin entirely — removing it fully (not just disconnecting) is what clears the stale registration. Deleting a still-connected plugin can leave the old registration behind, and you’ll hit the same error next time.
  3. Add it again (Browse plugins → +) with the server URL for the account and region you want (shown under Settings → Connect AI Agent in the Clment web app), and authorize.
