Claude
Open claude.ai or Claude Desktop and go to CustomizeConnectors.
Click + Add, then Add custom connector. The Add to Claude button opens this dialog already filled in.
Name it Glesso, paste this as the MCP server URL, leave the other settings as they are and click Add.
https://mcp.glesso.com/mcpClick Connect. Glesso opens: check the app and the account, then click Allow.
Start a new chat, turn Glesso on under +Connectors and ask it something that needs a service you connected, for example “What's on my calendar today?”.
Good to know
- The Free plan can add one custom connector.
- Team and Enterprise: an owner adds Glesso once under Organization settingsConnectorsAddCustom. Each member then clicks Connect and signs in.
- Claude's mobile apps use the connectors added on the web or in Desktop.
If it doesn't work
- “Couldn't reach the MCP server”: check the URL is exactly
https://mcp.glesso.com/mcp. - “Authorization with the MCP server failed”: remove the connector and add it again.
- The connector shows Connect or Reconnect when it needs you to sign in again.
New to Glesso?
Create an account and connect a service first. Onboarding then shows this guide beside a live check that turns green at your app's first tool call.
