Glissandoo API
A read-only API to integrate your groups, events and members data. With OpenAPI, an MCP server and OAuth 2.1.Glissandoo's public API lets external integrations and AI agents query the same information a user sees in their groups, always respecting their permissions. The first version (v1) is read-only and shares its contract, identity and quota across REST/OpenAPI and MCP.
What you can query
Active groups, group data, events and participants, members and instruments, forecast and attendance metrics, and metadata for the visible repertoire.
Authentication
Authenticate with an API key (x-api-key or Bearer header) or with OAuth 2.1 and PKCE, designed for MCP clients. The only v1 scope is public-api:read.
For AI agents
The remote MCP server exposes the same queries as tools, so compatible agents can discover and run them. Find an agent-friendly summary at /llms.txt.
