Best for
  • Developers building SceneView 3D/AR apps (Android, iOS, Web) who already use or want to adopt Rerun.io for debugging.
  • Teams that need replayable AR session evidence for bug reports and post-mortem analysis.
  • Debugging scenarios that combine SceneView AR poses, planes, and cloud anchors with Rerun's timeline visualization.
  • 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 not using SceneView or Rerun.
  • End users of a released application (this is a debugging tool, not a user-facing feature).
  • Teams that require an officially maintained Rerun.io MCP server and do not accept a community-maintained implementation.
  • 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
  • No dedicated permission list is published in the source material.
  • Based on the described features, the server may fetch and execute the npm package and its dependencies via npx.
  • It may launch local Python sidecar processes (Rerun SDK).
  • It may write local .rrd recording files and may start or interact with a local web viewer instance.
  • 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
  • The server is community-maintained by SceneView, not by Rerun.io, so standard supply-chain and local-execution risks apply.
  • The npm package and its dependencies may introduce third-party code; pin the version and review the published package before relying on it.
  • The server may process AR session data, so avoid using it with sensitive data in unfamiliar environments.
  • If Python sidecar dependencies are missing, features may fail, and errors may only appear in client logs.
  • 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
