@MCPForUnity/Editor/Windows/Components/ClientConfig/McpClientConfigSection.cs:
- Around line 552-583: Add a refresh failure callback to the
`RefreshClientStatus` request so an uncaught refresh exception sets the selected
client to `McpStatus.Error`, re-enables JSON copying, and refreshes the UI.
Update `EditorAsyncRefresh.Request` and its polling failure path to accept and
invoke that callback only for the current request, while preserving the existing
safe warning log.

…resh throws EditorAsyncRefresh only logged a warning when the refresh work threw, so the selected client stayed on "Checking..." with Copy JSON disabled. Add an optional failure callback, called only for a request that is still current, and use it to put the selected client into the Error state. The path, JSON and steps fields still described the previously shown client, so clear them and keep Copy JSON disabled.

Included review availability: This review used your included allowance. Your plan provides up to 10 included reviews per hour; 3 remain after this review.
After a refresh succeeded and a later one failed, displayedContext still held the earlier result, so the Claude path, the project directory and the project directory override flag kept showing settings that may no longer apply next to the Error status. Clear the context and show "Unavailable" on every current failure.

Description
Fixes an issue where TCP connection checks, executable discovery, uv validation, and client configuration reads block the Editor main thread when the MCP for Unity window regains focus. The refresh process retrieves the required settings on the main thread, performs I/O on a worker, and then updates the display.
Type of Change
Changes Made
Compatibility / Package Source
#beta,#main, tag, branch, orfile:): Verified this branch, created from beta, through a file: reference in a separate test project.Packages/packages-lock.json(if using a Git package URL): Not applicable (file: reference). The base is 142ea0a.Testing/Screenshots/Recordings
cd Server && uv run --extra dev pytest -q tests): 1,575 passed, 18 skipped.Before the fix, validating a slow executable took approximately 505ms, and the response-time regression test failed. After the fix, the same test passed. Also verified 12 focus refreshes in the actual window using an executable that takes 1 second; the maximum refresh call duration was approximately 0.38ms. Confirmed that Editor updates continued, configuration files remained unchanged, the verification settings were restored, and the display worked at widths of 500, 768, and 1000.
Ran
bash tools/check-unity-versions.sh. The specified versions 2021.3.45f2, 2022.3.62f1, 6000.0.75f1, and 6000.4.8f1 were all skipped because they were not installed.Documentation Updates

Fixes #1238
Additional Notes
Verification on an actual machine running Windows 11, the reported environment, has not been performed. The native verification performed used the Unity version listed above on macOS and covered Editor operations. The change adds no Unity-version-specific code paths and does not change any MCP tools.
Fork CI verification
Checked the GitHub Actions results for the same commit
b9345fa8dbd890338d9ffd0a83e87af6a7fa78ea. The Python tests succeeded, as did the harness tests that run without Unity.C# compilation also succeeded with Unity 6000.0.75f1. Runtime and Editor were compiled for each of the Windows, macOS, and Linux configurations.
The E2E tests and the Unity Editor tests that require a license were skipped.
The upstream GitHub Actions are waiting for a maintainer to approve the run for the current commit. The CI successes above are results from runs on the fork that verified the same commit.

Because the path, JSON and steps fields still described the previously shown client, they are cleared and Copy JSON stays disabled. New tests cover a faulted request, a superseded request, success, and a throwing failure handler. A second commit also clears the earlier Claude path and project-directory context on every current failure, so a later failure never shows settings from an earlier success.Verification for the latest commit:
