Greptile Summary

This PR updates four npm dependencies across the monorepo, automatically generated by Dependabot:

Security Updates:

  • js-yaml 4.1.0 → 4.1.1 - Fixes a prototype pollution vulnerability in the YAML merge operator (<<). This is a critical security patch that should be merged.

Feature Updates:

  • @modelcontextprotocol/sdk 1.20.2 → 1.24.0 - Updates to MCP spec 2025-11-25 with new Tasks API, improved SSE reconnection behavior, OAuth enhancements (client credentials flow, HTTP issuer URLs in dev mode), Zod 4 compatibility fixes, and bug fixes for JSON parsing and header normalization
  • better-auth 1.3.12 → 1.4.5 - Includes bug fixes for cookie chunking when exceeding limits, multi-session endpoint handling with invalid signatures, additional fields default values during session creation, user-agent handling, and adds SCIM custom media type support
  • glob 11.0.3 → 11.1.0 (scripts directory only) - Minor version bump with no breaking changes

All updates appear to be non-breaking and include improvements and bug fixes. The js-yaml security fix makes this PR important to merge promptly.

  • Score of 5 reflects: (1) automated Dependabot PR with clear dependency updates, (2) includes critical security fix for js-yaml prototype pollution, (3) all updates are minor/patch versions with no breaking changes documented, (4) updates include bug fixes and improvements to existing functionality, (5) no custom code changes that could introduce bugs
  • No files require special attention - all changes are straightforward dependency version bumps in package.json files
