Connect Entergram to Claude (MCP)

Entergram exposes a remote Model Context Protocol (MCP) endpoint, so you can plug it into Claude as a custom connector and query your workspace, chats, contacts and analytics directly from a Claude conversation.

What you’ll need

• A Claude account with access to Custom Connectors (claude.ai)
• An Entergram workspace with owner or admin access (Developer tab requires it)
• 2 minutes

Step 1 — Open Claude’s connector settings

Go to claude.ai/customize/connectors and click Add a new connector.

Step 2 — Fill in the custom connector popup

In the popup that opens:

1. Name — type anything you’ll recognize. We recommend Entergram.
2. Remote MCP URL — paste:

   https://mcp.entergram.com/mcp

3. Expand Advanced Settings (you’ll need it for the OAuth client ID in a moment).

Leave the popup open — you’ll come back to it.

Step 3 — Create an OAuth client in Entergram

In a new tab, open Entergram and go to Settings → Developer.

1. Click Create new OAuth client
2. Click the Preset: Claude Web Connector button — this fills in the redirect URL and connector metadata for you
3. Confirm the scope checkboxes match what you want Claude to see (workspace, chats, contacts, etc.)
4. Click Create
5. Once the client is created, click Copy client ID

Step 4 — Paste the client ID into Claude

Switch back to the Claude connector popup:

1. Paste the copied client ID into the Client ID field under Advanced Settings
2. Leave Client Secret empty — the Claude Web preset uses public-client OAuth (PKCE), so no secret is needed
3. Click Add a connector

Step 5 — Connect and authorize

Claude will now show your new Entergram connector in the list.

1. Click Connect
2. You’ll be redirected to Entergram’s consent screen
3. Click Allow
4. You’ll bounce back to Claude — the connector is now live

Verifying it works

Open a new Claude chat, enable the Entergram connector, and try a prompt like:

List my Entergram workspaces and show the 5 most recent chats.

Claude will call the MCP endpoint over OAuth and stream results back into the conversation.

Revoking access

To disconnect at any time:

• From Claude — Connectors → Entergram → Disconnect
• From Entergram — Settings → Developer → find the OAuth client → Revoke. Revocation is immediate; Claude’s session will fail on the next tool call.

Troubleshooting

• “Invalid client” on Connect — the client ID was pasted with a trailing space, or the OAuth client was revoked. Re-copy and try again.
• Consent screen never loads — make sure you used the Preset Claude Web Connector when creating the OAuth client; custom redirect URLs won’t match.
• Tool calls return 403 — the OAuth client’s scopes are too narrow. Edit the client in the Developer tab, add the missing scope, reconnect from Claude.
