What this MCP does

Acts as a stateless MCP gateway that proxies hosted MCP servers and streams OpenTelemetry spans, sessions, metrics, and runtime configuration.

prism_help
How to use Prism
Returns connection instructions: how to set the upstream MCP server (X-Prism-Upstream header or ?upstream= query param), the query-param config keys for header-less clients, how destinations and the borrowed-token model work, and example client configs. Start here if you are an agent discovering Prism for the first time.

prism_info
Prism service info
Returns Prism's service identity and runtime state: version, transport, public URL, capture default, and the number of MCP sessions currently being traced. Use this to confirm which Prism deployment you are talking to and whether it is healthy before configuring an upstream.
