Tell your assistant your event page and who should share (attendees, speakers or sponsors), and it creates the event, designs the share card with you, shows you a preview to approve and hands back a live share link. Built for B2B event organizers, and included in every plan and the 7-day free trial. Server address: https://attendir.com/mcp [ Start Free Trial ](https://attendir.com/register) [ Connect Your Assistant ](#assistants) How It Works ## From a chat to a live share campaign 1 ### Connect Add https://attendir.com/mcp to your assistant. Sign in to Attendir (or create an account) and click Allow. 2 ### Ask Tell it what you want, for example: "Set up an attendee share campaign for our conference page." It reads the name, dates and place from the page. 3 ### Approve and share Your assistant shows you the share card with a sample photo and name. Once you approve, the campaign goes live and you get the share link and embed code. Assistants ## Which assistants can connect You need an Attendir account (the 7-day free trial works) and an assistant that supports remote MCP servers with OAuth sign-in. We mark an assistant as tested once we have set up a campaign with it ourselves. ### Claude Tested claude.ai, the Claude desktop and mobile apps Add https://attendir.com/mcp as a custom connector, sign in to Attendir and click Allow. [Step-by-step guide for Claude →](https://attendir.com/integrations/claude) ### Claude Code Tested The command line Run the command below, then run /mcp in Claude Code to sign in. ```bash claude mcp add --transport http attendir https://attendir.com/mcp ``` ### ChatGPT Not yet tested On ChatGPT plans that allow custom connectors Add https://attendir.com/mcp as a custom connector with OAuth sign-in. Attendir accepts ChatGPT's sign-in return address, but we have not tried it end to end yet. ### Other MCP clients Not yet tested Such as code editors and desktop tools Clients that support remote MCP servers with OAuth sign-in in the browser, and return to a local address on your computer, should connect with the server address alone. Clients that return to their own app link cannot connect yet. Connected a different assistant? Tell us how it went at and we'll add it here. In Your Control ## What an assistant can and can't do The MCP server covers campaign setup. Attendir never posts to LinkedIn through it, and anything that reaches your attendees, or can't be undone, stays with you in the Attendir web app. It can - See your events and campaigns, and how many people shared each - Create and update events, from your event page and with your logo - Make share cards: from a template, a custom design or your own image - Create and update campaigns for attendees, speakers or sponsors - Give you share links and the embed code It can't - Post to LinkedIn: every attendee shares by clicking Share themselves - See who shared - Delete anything - Send invites, run the raffle, change integrations or billing - Put a campaign live without the card you approved Tools ## The 12 tools your assistant gets Your assistant picks the right tool for each request. You don't need to name them.

Sign-in OAuth 2.1 authorization code flow with PKCE (S256 only) and dynamic client registration. Access tokens last an hour; refresh tokens rotate. Sign-in returns only to claude.ai, chatgpt.com or a local address on the user's computer. Protected resource metadata https://attendir.com/.well-known/oauth-protected-resource/mcp An unauthenticated call gets a 401 whose WWW-Authenticate header points here. Authorization server metadata https://attendir.com/.well-known/oauth-authorization-server Server card https://attendir.com/.well-known/mcp/server-card.json Name, version, endpoint, sign-in and the tool list, for registries and agents. More detail: [how sign-in works](https://attendir.com/auth#mcp-oauth) · [developer docs](https://attendir.com/docs#mcp) · [security](https://attendir.com/security) · [privacy policy](https://attendir.com/privacy-policy) FAQ ## MCP Server FAQ **What is MCP?** The Model Context Protocol is an open standard that lets AI assistants use tools from other apps. Attendir runs an MCP server at https://attendir.com/mcp, so an assistant you connect can set up share campaigns in your Attendir account. **Which AI assistants work with Attendir?** We built and tested it with Claude: claude.ai, the Claude desktop and mobile apps, and Claude Code. ChatGPT and other MCP clients that sign in through the browser and return to chatgpt.com or to a local address on your computer should work the same way, but we have not tested them yet. **Does it cost extra?** No. The MCP server is included in every Attendir plan and in the 7-day free trial. Your AI assistant may need a plan that allows custom connectors. **Can an assistant post to LinkedIn for my attendees?** No. Attendir never posts to LinkedIn through the MCP server. Every attendee, speaker or sponsor shares by clicking Share on their own share page. **Can an assistant see who shared?** No. It sees how many people shared each campaign. Who shared, the raffle and the full results stay in your Attendir dashboard. **How do I disconnect an assistant?** In Attendir, open Profile, then Connected AI assistants, and click Disconnect. Its access stops at once.
