What is Spanly?
Observability and tracing for MCP servers in production.
Spanly is observability and monitoring for Model Context Protocol (MCP) servers. It captures every interaction between AI agents and MCP servers, visualizes each request/response with detailed timing breakdowns, tracks error codes and stack traces, and surfaces latency bottlenecks. Connect via a one-line hosted MCP, drop in the SDK, or run the CLI for servers you can't instrument directly.
