- Updated integration tests to include assertions for `meta` being
`null` in the `listTools`, `listResources`, `readResource`, and
`callTool` results.
- Renamed test cases in `SseServerIntegrationTest` for clarity.
- Added (deprecated) synthetic constructors for various request
parameter classes.
- Enhanced naming conventions and structure in integration test cases.
- Replaced `throw Error(...)` with `error(...)` for cleaner error
handling.
## Motivation and Context
To verify backwards-compatibility after schema change
## How Has This Been Tested?
CI, integration tests, regression tests (samples)

Implement the last version of the mcp schema and complete restructuring
of the mcp schema implementation from a monolithic `types.kt` file into
separate files.
- #158
- #185
- #353
- #298
- #248
## Motivation and Context
The previous implementation of the mcp schema was outdated and contained
several issues. In addition, it stored all mcp types in a single large
file, which made maintenance and further development more difficult
## How Has This Been Tested?
All tests passed
## Breaking Changes
Yes. The new types are now located in a separate package. Additionally,
many types have new parameters and modified constructors

Update Kotlin-MCP-Server with STDIO support, logging & CORS
### Summary
- Added support for STDIO transport mode (default behavior).
- Configured CORS and migrated SSE server to Ktor's Netty engine.
- Redirected logs to `./build/stdout.log` and updated log levels.
- New `TestEnvironment` setup for integration testing.
- Enhanced documentation with examples for server execution and MCP
Inspector usage.
- Introduced shadow JAR plugin for building runnable artifacts.
### Motivation and Context
Improves server versatility and developer experience by enabling STDIO
and refining setup.
## How Has This Been Tested?
Unit tests, tested locally (see README.md in sample)
**NB! sse plain configuration is not working at the moment**

No

- updated the sdk version in all examples
- fixed `kotlin-mcp-server` example (#331)
## Motivation and Context
Removed the WASM example, as it duplicates the JVM example and only adds
unnecessary complexity

# #302 Update samples build workflow
- Introduce workflow to build samples independently from the main
project
- Keep building samples against the current snapshot version of the SDK.
Update composite build configuration.
- Temporarily disable "samples/kotlin-mcp-server": the multiplatform
project is broken. **It doesn't compile for me even on the main
branch**. Not working with [MCP
Instepcor](https://modelcontextprotocol.io/docs/tools/inspector),
because CORS is not configured. Deserves a separate PR to fix.
## Motivation and Context
Samples should be independently buildable

Don't bind the sample server to `0.0.0.0` by default as that exposes the
server to anyone else on the local network.
If anyone were to use these samples as staring points to build larger
services, those servers would thus expose developers to attack
immediately upon launch.
I'd prefer if we avoided that 😆
## Motivation and Context
🔒 Security

<!-- Have you tested this in a real application? Which scenarios were

I haven't checked out the code locally to verify it works. All the
editing to the code was done on GitHub.com

Introduce a `ServerSession` to manage multiple connections to the mcp
server. `Protocall` logic of the `Server` was moved to `ServerSession`,
while MCP resources logic remained in `Server`
## Motivation and Context
1. Fix the multiple connection issues reported for SSE transport
2. Avoid server duplications during configurations: currently every connection
creates a session, but the server stays single
## How Has This Been Tested?
Added `SseIntegrationTest` and `WebSocketIntegrationTest` integration
tests to check connection with single and multiple clients
## Breaking Changes
This change caused several depreciations:
1. The `Server` -> `Protocol` inheritance (which caused single
connection issue) should be removed in future releases, now, all the
methods inherited from `Protocall` marked as `Deprecated` with a
`Warning`
2. Websocket Ktor server initialization changes in order not to create
server instance per connection
