Stateless MCP

An informal shorthand for serving MCP requests without retaining transport session state between requests.

Example

A stateless HTTP deployment can route independent requests across instances when the application keeps required state elsewhere.

The distinction that matters

Transport sessionlessness does not imply stateless application data; protocol revision and SDK behavior determine available features.
