<!-- Provide a brief summary of your changes -->
## Motivation and Context
The
[schema](cca15204f6/schema/2025-03-26/schema.ts (L192))
for the InitializeResult contains an optional 'instructions' string
## Additional context
The instructions string is included in the schema for for version
"2025-03-26"
The instructions in the Server class are given as a provider function
with the result of the provider propagated to the underlying
ServerSession. As the ServerSession change is meant to allow for a
'Singleton scoped' server class, this provides the ability to
dynamically modify the instructions at the server level but have them be
immutable per session.
This also refactors the `serverInfo` and `instructions` properties to be
protected. This `Server` class is open and meant to be overridden, there
is no harm in having these immutable properties available to subclasses.
This adds the serverInstructions to the client as returned from the
InitializeResult. This is used to verify the response in the Server
tests.
<!-- Provide a brief summary of your changes -->
Replace the CIO dependency with only server/client core dependency.
## Motivation and Context
<!-- Why is this change needed? What problem does it solve? -->
In order to minimize the size of package. There are probably other
existing engines like Netty/Tomcat(server) or Java/OkHttp/Apache(client)
in the classpath. So we can reuse existing infrastructure.
## How Has This Been Tested?
<!-- Have you tested this in a real application? Which scenarios were
tested? -->
I have run:
- kotlin-sdk-client: jvmTest, jsTest
- kotlin-sdk-test: jvmTest, jsTest
- kotlin-sdk-server: allTests
- All `build` of samples
I have an issue about `samples/kotlin-mcp-server`.
`io.modelcontextprotocol` is not found in `commonMain`.
## Breaking Changes
<!-- Will users need to update their code or configurations? -->
Yes. They need to `implementation` CIO engine manually if they use it in
their app.
