Best for
  • Developers who need intent-based search
  • Teams using coding agents
  • Users who want multi-format search from a terminal
  • Engineering teams scaling AI coding agents while controlling spend
  • Platform teams that need auditable, rollback-aware agent execution records
  • Organizations using multiple agents (Claude, Codex, Gemini) under one governed flow
Not for
  • Workflows requiring only exact matches, regular expressions, or symbol tracing
  • Clients requiring a confirmed MCP tool or transport integration
  • Environments where files must not be uploaded to a cloud service
  • Developers who just want a simple code-completion helper without run governance
  • Teams unwilling to accept local JSONL run records with HMAC signing
  • Environments without a supported adapter (Claude/Codex/Gemini CLIs, direct provider, or verifier-only)
Required permissions
  • Read project files and sync them according to .gitignore and .mgrepignore
  • Upload eligible files to a Mixedbread Store
  • Authenticate through browser login or MXBAI_API_KEY
  • Monitor file changes continuously when watch mode is active
  • Read/write access to the configured repo root (writable scope restrictable via --allow-path/--deny-path)
  • Ability to invoke the chosen agent CLI (Claude/Codex/Gemini, etc.) and its underlying model account
  • Local disk writes for run records, receipts, and share outputs (share/run-receipt., etc.)
  • Execution of user-configured verifier commands (e.g. npm test)
Risks and side effects
  • Files are synchronized to a cloud-hosted Mixedbread Store
  • The default limits are 1MB per file and 1,000 files per directory, though configuration can change them
  • Background synchronization may continue during agent sessions and contribute to platform usage
  • Web search and generated answers may include external information that requires verification
  • Verifier commands are executed; poorly chosen verifier commands carry security risk despite preflight policy checks
  • Cost and token figures may be estimates (labeled with provenance) and should not be treated as settled accounting
  • Receipt integrity must be verified before use as trustworthy evidence; missing rollback evidence is flagged as EVIDENCE_BOUNDARY
  • Policy defaults come from martin.config.yaml and can be overridden by CLI flags; misconfiguration can loosen safety boundaries
