Release Notes

modelcontextprotocol/go-sdk (github.com/modelcontextprotocol/go-sdk)

v1.5.0

Compare Source

This release is equivalent to v1.5.0-pre.1. Thank you to those who tested the pre-release.

In this release we introduce important enhancements to the client-side OAuth flows. We also introduce several smaller fixes and improvements.

Stabilization of client-side OAuth APIs

As previously communicated, we're stabilizing the client-side OAuth APIs in v1.5.0. This means that the mcp_go_client_oauth build tag will no longer be required to compile the functionality and standard backward compatibility guarantees apply from now on.

Compared to the experimental support published in v1.4.0, we made some backwards incompatible changes:

  • auth.AuthorizationCodeHandlerConfig.AuthorizationCodeFetcher's type was changed from func(context.Context, *auth.AuthorizationArgs) (*auth.AuthorizationResult, error) to auth.AuthorizationCodeFetcher which is a reusable definition carrying the same underlying function type.
  • auth.AuthorizationCodeHandlerConfig.PreregisteredClientConfig was removed and replaced with auth.AuthorizationCodeHandlerConfig.PreregisteredClient which uses a newly introduced oauthex.ClientCredentials type. The type used previously (auth.PreregisteredClientConfig) has been removed.
  • Deprecated functionality has been removed from both auth and oauthex packages.

Enterprise Managed Authorization support added

Support for Enterprise Managed Authorization has been added to auth/extauth package. Huge thanks to @​radar07 for the implementation!

Note: this support is part of an official MCP extension and is not part of the core protocol. The support of this functionality is not covered by the principles defined in SDK tiers.
