Overview
Gatsby MCP Server
An MCP server that lets your AI tool query your Gatsby contacts, events, and RSVPs in natural language. Limited release — reach out to enable for your organization.
Your AI tool, connected to Gatsby.
The Gatsby MCP server exposes your contacts, events, RSVPs, and guest history to any MCP-compatible AI client. You ask a question in plain English. Your AI tool calls Gatsby on your behalf and answers using your own data.
Sessions are tied to your Gatsby account, so what the AI can see is exactly what you can see in the app.
Find people you haven’t invited yet
”Recommend 10 people from my contacts I haven’t invited to any of my events yet, who’d fit my next founder dinner.”
Plan a trip around your network
”I’m in New York next Tuesday. Who from my contacts is based there and worth a 30-minute coffee?”
Set up breakout pairings
”For my upcoming LP meeting, suggest 1:1 breakout pairings across the confirmed attendees and explain the rationale for each pair.”
Segment by profile and history
”Find the founders in FinTech from my contacts who have been to at least one of my past events.”
The MCP is alpha. Some prompts will land cleanly. Others will miss. We’re refining the patterns with our first cohort of customers and welcome the feedback.
The MCP server is in alpha and free for participating customers today. Gatsby may turn it into a paid add-on later at our discretion. We’ll let alpha customers know well in advance of any change.
-
Reach out to Gatsby. Talk to your account team to request access. We’ll enable the MCP server for your organization on the backend.
-
Turn on the MCP server in Team Settings. Once we’ve enabled the feature, a Super Admin or Admin opens Team Settings > MCP and confirms Enable MCP Server is on. This is the master switch for your organization.
-
Decide whether to allow destructive actions. In the same settings panel, Allow Destructive Actions is off by default. Leaving it off means the MCP is read-only: your AI tool can answer questions about your data but cannot create, update, or delete anything. A Super Admin or Admin can turn it on. With it on, the AI can write back to Gatsby — create contacts, edit events, modify guest lists — within the permissions of whoever connected the AI tool.
-
Connect your AI tool. Point your AI client at the MCP endpoint:
https://mcp.gatsby.events/mcpThe first time you connect, Gatsby opens a web login in your browser. Sign in with your Gatsby account, approve the connection, and you’re done — no keys to copy or store. This is the recommended path. See the per-client instructions below.
Prefer an API key? Clients that don’t support the web login — and automated, non-interactive setups — can authenticate with a personal key instead. Generate one under Account Settings > API Keys and paste it into the connector. Treat it like any other production secret: anyone with the key can act as you, subject to your permissions in the app.
Add the connector
Section titled “Add the connector” Claude Desktop
-
Make sure you’re on the latest version of Claude Desktop. Download from claude.ai/download if needed.
-
Open Claude Desktop. Click your profile in the bottom-left of the sidebar (or press Cmd+,) to open Settings.
-
In Settings, click Connectors, then click Customize.
-
In the Connectors list, click the + button in the top-right to open the Add custom connector modal.
-
Enter the connector details:
Name: Gatsby Remote MCP server URL:
https://mcp.gatsby.events/mcp -
Click Add. A browser window opens asking you to sign in to Gatsby — use your Gatsby account and approve the connection.
-
Gatsby will appear in the connectors list and in the tools picker (the slider icon near the composer). Try a prompt: “Using Gatsby, find 3 people from my contacts who’ve been to more than one of my events.”
claude.ai (web)
-
Go to claude.ai. Open Settings, click Connectors, then click Customize.
-
In the Connectors list, click the + button in the top-right to open the Add custom connector modal.
-
Enter the connector details:
Name: Gatsby Remote MCP server URL:
https://mcp.gatsby.events/mcp -
Click Add, then sign in to Gatsby in the popup and approve the connection.
-
Gatsby will be available as a tool in any new chat.
Claude Code (CLI)
-
In any shell, run:
Terminal window claude mcp add --transport http gatsby https://mcp.gatsby.events/mcp -
Launch Claude Code with the
claudecommand. -
Type
/mcp, select gatsby, and authenticate. A browser window opens — sign in to Gatsby and approve the connection. -
Back in Claude Code,
gatsbyshows as connected. Try a prompt: “Using Gatsby, find 5 founders in FinTech from my contacts.”
To use an API key instead, append --header "Authorization: Bearer YOUR_API_KEY" to the claude mcp add command, using a key from Account Settings > API Keys.
ChatGPT, Cursor, Gemini, and other clients
Any MCP-compatible client can connect to https://mcp.gatsby.events/mcp. The endpoint is the same, and most clients sign you in through the same Gatsby web login. Only the UI for adding a custom connector varies by tool.
- ChatGPT supports remote MCP connectors on Team, Enterprise, and Pro plans
- Cursor supports MCP servers via its settings
- Gemini support is rolling out in select clients
Clients that don’t support the web login can use a personal API key from Account Settings > API Keys instead. If your daily driver isn’t listed, mention it when you reach out and we’ll walk through setup with you.
Is my data used for training?
No. Gatsby does not feed your data into any model. The MCP server logs which tools are called and what data is returned so we can spot usage patterns during the limited release. Those logs stay internal to the Gatsby team. We don’t see the natural-language prompt you typed unless you share it with us.
What does 'Allow Destructive Actions' actually permit?
With it off (the default), the MCP server is read-only. Your AI tool can answer questions but cannot change anything in Gatsby.
With it on, the AI can perform writes through the MCP server — create contacts, update events, add or remove guests from a list, edit RSVP status, and delete records. Writes follow the same permission rules as the app: whoever connected the AI tool can only do things they’re allowed to do in Gatsby itself.
Only a Super Admin or Admin can change the toggle. We recommend leaving destructive actions off until you’ve spent time with the read-only experience and trust the prompts you’re running.
Which AI clients work?
Any client that supports the Model Context Protocol. That includes Claude Desktop, claude.ai, Claude Code, ChatGPT (on Team, Enterprise, and Pro plans), Cursor, and a growing list of others. The endpoint is the same regardless of which client you use.
Do I need an API key?
No. The recommended path is to sign in with your Gatsby account when you add the connector — nothing to copy or store. API keys are an alternative for clients that don’t support the web login, or for automated setups. Generate one under Account Settings > API Keys when you need it.
How do I revoke access?
If you connected by signing in with your Gatsby account, remove the Gatsby connector in your AI tool to end the session. If you connected with an API key, open Account Settings > API Keys and delete it — any client using that key loses access immediately.
Who can see what through the MCP server?
Each user connects with their own Gatsby account — through the web login or a personal API key — and the MCP server returns only the data that user can see in the app. If a teammate isn’t allowed to view a given event in Gatsby, the MCP can’t show it to them either.
How is the MCP server different from the Gatsby API?
The Gatsby API is a developer tool — REST endpoints, JSON, scripted integrations meant for engineers building software on top of Gatsby. The MCP server is a natural-language layer your AI tool drives on your behalf. Both read from and write to the same underlying records. Use the API when you’re building an integration. Use the MCP when you want to ask questions of your own data without writing code.
What does it cost?
The MCP server is free for participating customers during the alpha. Gatsby may turn it into a paid add-on later at our discretion. Alpha customers will get notice well in advance of any pricing change, and you’ll get first say on the shape of the offer.
How do I get access?
Contact your Gatsby account team. We’ll enable the MCP server for your organization on the backend, after which a Super Admin or Admin can turn it on in Team Settings > MCP and individual users can connect their AI tool.
