The Type Server Protocol (TSP) is a JSON-RPC protocol for asking a type server for Python analysis data. A type server maintains the type-analysis state for a workspace and answers requests for the protocol version, snapshots, Python search paths, import resolution, and type queries (computed, declared, and expected types).
The protocol uses Language Server Protocol (LSP) data shapes and conventions where they are useful, such as Position and Range, and it represents URIs as strings the same way LSP does. TSP methods use the typeServer/ prefix.
TSP uses semantic version strings for client/server compatibility checks. While the protocol is in the 0.x line, minor version changes may be breaking. Patch version changes remain backward compatible within the same minor line.
