Summary

Initial MCP token loading and reset responses did not share ownership, and reset was not single-flight. An older mount/reset response could overwrite the newest server token, duplicate resets could generate multiple tokens, and unmounted callbacks still updated state/feedback. This change serializes reset, invalidates mount ownership, exposes reset busy state, and suppresses late callbacks.

Affected surfaces

  • Frontend / Web
  • Backend / API / Storage
  • Database plugin / Driver
  • JCEF / Desktop packaging
  • CI / Build / Release
  • Documentation only

Verification

  • Commands and results:
    • Red tests reproduced mount-over-reset overwrite, duplicate resets, and post-unmount callbacks.
    • MCP lifecycle/token tests and main-navigation prebuild entry: passed.
    • Targeted ESLint and full Community build/bundle verifier: passed.
    • Fork code and CodeQL checks: passed.
    • Merge-tree with Notification and SQL parser repairs: passed.
  • Manual verification: N/A - deferred bridge promises reproduce token response ordering without real reset operations.
  • UI evidence: N/A

Risk and compatibility

  • Public API or stored data: No API or token format changes.
  • Database or driver compatibility: N/A.
  • Network, privacy, or security: Prevents display/copy of an already superseded MCP token.
  • Community / Local / Pro boundary: Shared Community MCP settings.
  • Backward compatibility: One reset retains existing bridge behavior; concurrent confirmations now join/ignore while busy.

Reviewer map

  • Start here: McpTokenRequestCoordinator, mount token effect, and resetToken.
  • Failure condition: two resets start concurrently, old mount data wins, or unmounted callbacks commit.
  • Rollback or disable path: Revert commit 94b18059f264e51fd35a4a8dfd748e75d1f969be; no migration is required.

Contributor declaration

  • I linked the Issue that defines this change.
  • I tested the affected behavior and reported the actual results above.
  • I did not include credentials, private data, or generated build output.
  • I disclosed substantial AI assistance below, or this PR contains no substantial AI-generated code.

Risk and compatibility
  • Public API or stored data: No API or token format changes.
  • Database or driver compatibility: N/A.
  • Network, privacy, or security: Prevents display/copy of an already superseded MCP token.

Summary
Initial MCP token loading and reset responses did not share ownership, and reset was not single-flight. An older mount/reset response could overwrite the newest server token, duplicate resets could generate multiple tokens, and unmounted callbacks still updated state/feedback. This change serializes reset, invalidates mount ownership, exposes reset busy state, and suppresses late callbacks.

  •  Documentation only
Verification
  • Commands and results:

    • Red tests reproduced mount-over-reset overwrite, duplicate resets, and post-unmount callbacks.
