Connect your AI assistant to RentFig

Anthropic · web, desktop & mobile

Plans that can add it: Free (one custom connector), Pro, Max, Team and Enterprise

1. In Claude on the web or desktop, open Settings → Customize → Connectors.
2. Click Add, then Add custom connector.
3. Name it RentFig and paste the RentFig address. Leave the advanced settings as they are, then click Add.
4. Click Connect. A RentFig page opens: sign in (with two-step verification if you use it) and choose Allow read-only access.
5. In a chat, open the + menu → Connectors, make sure RentFig is switched on, and ask something like “Which of my tenants owe rent?”

• Team and Enterprise: an owner first adds RentFig under Organization settings → Connectors; each member then clicks Connect and signs in as themselves.
• On the Claude mobile app, a connector you've added on the web is available automatically.

OpenAI · web & desktop

• ○ Should work — not yet tested by us
• ✓ Connects straight away

Plans that can add it: Business, Enterprise and Edu, and Pro or Plus in developer mode — OpenAI changes which plans can add custom connectors, so check yours

1. Switch on developer mode: Settings → Apps (or Apps & Connectors) → Advanced settings → Developer mode. On a work account your admin may need to allow it.
2. Add a custom app or connector for an MCP server (in Settings → Apps, or Plugins → Add custom MCP server).
3. Name it RentFig, paste the RentFig address, choose OAuth for authentication and create it.
4. When asked, sign in to RentFig and choose Allow read-only access.
5. Start a new chat, add RentFig from the + menu, and ask something like “Which certificates expire next month?”

• OpenAI renames these menus often — if a name differs, look for “custom MCP server” or “custom connector”.

• ⚠ Needs “Allow other AI apps” switched on by the account owner

1. The RentFig account owner switches on Allow other AI apps in Settings → Integrations → AI assistants.

• Desktop apps that sign in through your browser on the same computer (for example Zed or Goose) usually connect without this setting.
