MCP100 Assessment

Watchlist / Tracking

Why we’re tracking it

Track index quality and tool-contract changes as repository-scale code search evolves

Reviewed · Documentation review; complete setup workflow not independently tested

Best fit

Semantic search across local or remote code repositories for coding agents.

What we know

Semble provides agent-oriented semantic search over local or remote repositories and is designed to run CPU-only without external AI APIs.

Maintenance / activity evidence

  • Observed (UTC)fix: Exit the MCP server immediately on stdin EOF or SIGTERM ( 282)

Verification gaps / watch-outs

  • Installation and comprehensive security have not been independently audited.
  • Reads indexed repository content.
  • Authentication not yet verified.
  • Sensitive access: Local or cloned repository content
  • The main risk is exposing repository content to the connected agent; the project states that indexing does not require external services.

All limitations / Review context

Does the MCP search surface still expose the documented indexing and retrieval behavior?

The bounded assessment reviewed the official README, repository notices, security policy path, and security page for known material public-tracking blockers. No such blocker was identified. This is a public-tracking assessment, not an installation safety certification.

  • The main risk is exposing repository content to the connected agent; the project states that indexing does not require external services.
  • Reads indexed repository content.
  • The project states CPU-only operation with no external services or API keys.
  • Sensitive access: Local or cloned repository content
  • Installation, client compatibility and comprehensive security have not been independently audited. Authentication and access depend on the configured services.
  • A project-specific SECURITY.md policy was not available at the fetched official path; the review remains limited to published repository notices.
  • No installation, runtime, client matrix, or complete tool-contract audit was performed in this review.
  • The fetched official SECURITY.md path returned HTTP 404; it was not treated as positive evidence.
  • Index quality depends on repository content and local resources.
