This commit fixes a critical type error in the MCP client session related to the SamplingFnT class. The issue was that the SamplingFnT class in the mcp.client.session module was using RequestContext with two type parameters, but the installed version of RequestContext only accepted one type parameter. Key changes: 1. Modified the MCPSamplingMessageHandler type to use a more flexible approach with the ellipsis (...) syntax for parameters 2. Updated related files to use this new approach 3. Removed explicit type annotations in handler methods This fix ensures that the VSCode MCP server dynamic URL feature works correctly without type errors, allowing the semantic workbench to properly connect to the VSCode MCP server.
… fix This commit adds detailed documentation explaining the SamplingFnT type error issue and its resolution. The documentation includes: 1. A clear explanation of the original error and its root cause 2. Detailed description of the changes made to fix the issue 3. Code examples showing the before and after states 4. Testing procedures used to verify the fix 5. Impact analysis of the fix on the VSCode MCP server dynamic URL feature This documentation will help developers understand the issue if they encounter similar problems in the future, and provides a reference for the technical details of the fix.
…rror reference This commit enhances the VSCode MCP server dynamic URL documentation by adding a reference to the SamplingFnT type error fix in the troubleshooting section. The update includes: 1. A new troubleshooting entry specifically for the SamplingFnT type error 2. A direct link to the detailed documentation (SAMPLING_FN_TYPE_ERROR_FIX.md) 3. Integration with the existing troubleshooting workflow This update ensures that users who encounter the SamplingFnT type error while using the VSCode MCP server dynamic URL feature can quickly find the solution and understand the technical details of the fix.
This commit updates the VSCode MCP server package management and configuration files to ensure compatibility with the SamplingFnT type error fix. The changes include: 1.
