Fixes modelcontextprotocol#103 Fix the issue where `server.request_context.meta` does not include the `progressToken`. * **Extract `_meta` field**: Extract the `_meta` field from request parameters and assign it to `message.request_meta` in `src/mcp/server/__init__.py`. * **Update `RequestContext`**: Update `RequestContext` instantiation to include `progressToken` in `src/mcp/server/__init__.py`. * **Allow extra fields**: Update `RequestParams` instantiation to include `model_config = ConfigDict(extra="allow")` in `src/mcp/types.py`. --- For more details, open the [Copilot Workspace session](https://copilot-workspace.githubnext.com/modelcontextprotocol/python-sdk/issues/103?shareId=XXXX-XXXX-XXXX-XXXX).

Thank you for this. This helped me figuring out a fix. I think my fix in #108 is more general and we should probably go down that route. I'll close out this PR. Thank you so much for the bug report and the attempted fix! |
