OpenAgenda — Claude Code MCP server: what it does, how to install
Connects event search, data review, and scheduling controls from OpenAgenda directly to your assistant.
claude mcp add --transport http mcp https://mcp.openagenda.com/mcpWhat OpenAgenda does
The server links your development environment with OpenAgenda to search, inspect, and update event records. It runs across clients supporting MCP either through a hosted HTTP transport or as a local stdio process.
Connecting over HTTP requires only the endpoint URL https://mcp.openagenda.com/mcp. Running the package locally via npx -y @openagenda/mcp demands environment variables: OA_API_KEY, OA_BASE_URL, OA_EXECUTOR, and OA_LOCAL_NO_SANDBOX. Without setting OA_API_KEY, local execution fails authentication.
What it helps with
- search listings on OpenAgenda
- review event parameters and schedules
- update event entries via API
Example prompts for the agent
- Search for upcoming tech conferences on OpenAgenda.
- Retrieve schedule details for this OpenAgenda event listing.
