Summary

AI summary

Run discovery now prefers a bounded append‑only index to keep latest/list queries responsive with large histories.

Full changelog

@martinloop/mcp 0.3.3

0.3.3 is the opt-in execution-controls release, including run-history reliability hardening for MCP clients that operate against large local run stores.

What changed

  • MCP run discovery paths now prefer a bounded append-only run index before falling back to full directory scans.
  • latest and list-style inspection flows stay responsive even when the runs directory contains large historical volume.
  • Compatibility behavior is preserved: if index entries are missing or stale, MCP falls back to canonical run-directory reads.
  • No runtime execution policy changes were introduced in this release.

Why this matters

MCP hosts such as Cursor, Copilot, and other IDE integrations frequently call latest/list inspection paths. This release reduces timeout-style failures caused by scanning very large run histories.

Compatibility

  • Breaking changes: none.
  • Tooling compatibility: this release remains compatible with existing MCP host integrations that use the same tool surface.
  • Migration requirement: none.

Quick check

npx -y @martinloop/[email protected]

Then call the MCP list/latest run tools against your normal runs root and confirm responses remain fast and stable.
