v1.0.0
Compare Source
This is a stable release of the Go SDK.
This release is functionally equivalent to v0.8.0, but formalizes a compatibility guarantee: going forward we won’t make breaking API changes. The API we have is not perfect, but it’s important that we commit to supporting it so that others can depend on the SDK without further churn. If we want to improve the current API in the future, we’ll do so in backward compatible ways, such as by deprecating and adding. For example, #396, #460 and #533 propose new functions that improve the ergonomics of the current API. Given the rate of change of the MCP spec, it seems likely that we’ll want to go to v2 at some point, but we should delay that event for as long as possible.
This release also marks a level of relative completeness. You should be able to implement essentially any behavior described in the MCP spec using the SDK (except client-side OAuth—see #19). See our feature documentation for information on how the SDK models different aspects of the spec.
Finally, this release represents a certain level of maturity. With the help of our contributors, we’ve endeavored to be responsive to bug reports, and as of writing have fixed 60 out of 61 bugs that have been reported against the SDK. Furthermore, the SDK is getting real-world usage both at Google and in the broader Go community. Much of this usage appears to be using the simpler
stdio
orsse
transports; we anticipate further bug reports and feature requests as the SDK is used in larger, distributedstreamable
servers.We owe a great deal of thanks to everyone who has filed bugs or contributed to the SDK. To date, we’ve accepted PRs from 58 distinct contributors, and many more people have filed issues or commented. We’d also like to thank those who have helped maintain the many other SDKs that compose the Go MCP ecosystem.
The plan now is to pay close attention to incoming bug reports, finalize client-side OAuth support, revisit our current set of proposals, and prepare for the next version of the MCP spec. Please use the SDK and continue to file issues. Thanks again!
What's Changed
Not much has changed since v0.8.0, though notably #539 partially addresses the security issue described in #526 (see also https://verialabs.com/blog/from-mcp-to-shell).

v0.8.0
Compare Source
This release exists to include the API change from #518, mentioned in the v0.7.0 release. It also includes a small change to remove extraneous API.
This concludes our API audit. Barring a realization over the weekend, we will cut v1.0.0 and any further API changes will be handled in a backwards compatible way.
API Changes
any
, to decouple the SDK's API from thegithub.com/google/jsonschema-go/jsonschema
package. Now that package is only used for inference (inmcp.AddTool
) and validation.Full Changelog: modelcontextprotocol/go-sdk@v0.7.0...v0.8.0
v0.7.0
Compare Source
This release fixes a couple bugs related to the
StreamableClientTransport
, and relaxes it to be less strict so that it can talk to certain servers that don't perfectly conform to the spec. It also updates togoogle/[email protected]
, which includes a couple backwards incompatible bug fixes (see below).For more details, see the v0.7.0 milestone.
API Changes
No changes in the API of the SDK itself, but the updated google/jsonschema-go@v0.3.0 contained the following incompatible bug fixes:
ForOptions.TypeSchemas
must be areflect.Type
, as incomparable values are not valid map keys.See #518 for a proposal to significantly decouple the SDK from the jsonschema-go package (though it would still be used for inference and validation). This decision blocks the v1.0.0 release.

v0.6.0

This release makes a couple minor API tweaks that arose in preparation for v1.0.0, and adds significant feature documentation in the
docs/
directory.This is a release candidate, and all release blocking issues have now been addressed. We will tag v1.0.0 following a final audit (see also #328).
