Tools & capabilities

IAMF Sentinel tools 5

  • iamf_validateFull conformance report on a `.iamf` / IAMF-in-MP4 file: S-code findings with severities, summary, stream facts. `strict` promotes WARN to failing.
  • iamf_inspectStructure orientation: profiles, codec configs (incl. Opus pre-skip), element/presentation/frame counts, OBU trim totals, MP4 edts/elst presence.
  • loom_compileCompile a Loom manifest (YAML/JSON) to its packaging plan — validate-only. Per-target backend/muxer routing with rationale, or M-code diagnostics.
  • loom_explainloom explain` as text: the compiled plan as its own justification.
  • loom_runCompile **and execute** a manifest: encode, mux, measure, and gate every output through the Sentinel validator. Returns per-target outputs (sha256), gate verdicts, measured loudness, and the run-ledger path. **Only registered when the server is launched with `--enable-run`.

Next Devtools MCP tools 4

  • nextjs_indexDiscover running Next.js dev servers and list each one's runtime MCP tools.
  • nextjs_callCall a runtime tool on a discovered server (errors, routes, logs, Server Actions).
  • nextjs_docsGateway.** Point the agent at version-accurate docs in `node_modules/next/dist/docs/`.
  • browser_evalGateway.** Point the agent at the [`agent-browser`](https://github.com/vercel-labs/agent-browser) CLI for browser automation.
