Model Context Protocol (MCP) server for Firefox DevTools automation (fork with Firefox management tools)

Query the Software Observatory catalog of epistemic sensors for software correctness. Built for humans and agents: every command emits JSON with --json.

Agents make claims, Reelier writes receipts - record an agent workflow once, replay it deterministically at 0 tokens, and get an asserted receipt on every run.

AI-powered CLI for BDD specs, coding constraints & acceptance testing. MCP-native.

Capture webhooks byte for byte, replay them to localhost with signatures intact, let an agent act through pipes it never holds keys for, and give several agents one signed room to write to.

Ensemble testing for front-end web quality

The agent runtime for React Native and Expo: an MCP server that sees the app the way React sees it, knows which file produced each element, acts without coordinates, and proves it works. Local only, zero dependencies.

The independent local harness for AI-repaired Playwright tests — it runs the tests itself, so a green run can't be faked.

Let coding agents verify UI changes on real iOS, Android, and web surfaces, then enforce reviewed proof in deterministic CI.
