Best for
  • Teams that want AI clients to operate GitLab project-management and collaboration workflows.
  • Users working with GitLab.com and self-managed GitLab instances.
  • Deployments needing read-only mode, toolsets, individual tool filters, or deny patterns.
  • Developers needing local stdio or remote HTTP MCP access.
  • 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
  • Projects that do not use GitLab or need GitLab API operations.
  • Static code-reading scenarios where GitLab credentials should not be granted.
  • Deployments that require REMOTE_AUTHORIZATION together with SSE.
  • Environments unable to securely manage personal, OAuth, cookie, or remote authorization credentials.
  • 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
  • GITLAB_PERSONAL_ACCESS_TOKEN is required unless another supported authentication method is used.
  • The token should have scopes required by the selected tools, such as api or read_api.
  • Write, delete, pipeline, and project-management tools require corresponding GitLab permissions.
  • GITLAB_READ_ONLY_MODE can expose only read-only tools.
  • Access can be constrained with GITLAB_ALLOWED_PROJECT_IDS, GITLAB_TOOLSETS, GITLAB_TOOLS, and GITLAB_DENIED_TOOLS_REGEX.
  • Wiki tools require USE_GITLAB_WIKI or the relevant toolset to be enabled.
  • 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
  • Tokens with the api scope or write tools may permit creating, changing, merging, or deleting GitLab resources.
  • Personal access tokens, job tokens, cookies, and OAuth tokens are sensitive credentials and should not be exposed in logs or shared configuration.
  • NODE_TLS_REJECT_UNAUTHORIZED=0 weakens TLS certificate validation and should only be used intentionally for invalid or self-signed certificates.
  • Remote HTTP deployments require correctly configured authentication, sessions, origins, hosts, and proxy trust settings.
  • download_job_artifacts and other download tools may save content to local paths.
  • 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
