Read Evenium events, guests, contacts and hotels; register guests and update contacts and statuses.
The publisher's own server: Ably MCP by usefulapi
Connects an assistant to an Evenium event account to read events, guests, sessions and contacts, and to invite guests or update statuses.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.usefulapi%2Fevenium/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Evenium credentials.

On first connect you will paste your Evenium API key. It is validated, stored per-user, and scoped to you. No keys in config files.
read tools are read-only; write tools mutate data (clients should confirm them); meta tools report usage, manage your subscription or send a feature request.
*Pro has a fair use limit of 10,000 tool calls a month on this server. For more, write to [email protected].
Pro covers this server only. Subscribe with evenium_upgrade (it returns a Stripe Checkout link). Cancel any time with evenium_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running evenium_upgrade before then undoes the cancel.
