Bug translation for vibe coders: plain-English diagnosis + paste-ready fix in your AI coding agent
Bug translation for vibe coders: plain-English diagnosis + paste-ready fix in your AI coding agent. The mushi mushi mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 11 defined tools rather than through you.
Plain-English diagnosis + a paste-ready fix, right inside Cursor and Claude Code. No log-reading. No second LLM API key for MCP.
Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
Everything the assistant can do here goes through one of these:
Catches — Thrown errors and silent UX bugs (dead clicks, slow screens, layout breaks)Output — Plain-English root cause + paste-ready fix, in your editorAuto-fix — Optional: sandbox agent opens a draft PRSetup — One command, no account required to tryArea — WorkingClassification — Haiku fast-filter, Sonnet deep + vision air-gap closed, structured outputs, prompt-cached prompts, pg_cron self-healing, **Stage 2 streaming viaSandbox — Provider abstraction; local-noop (tests) + e2b / modal / cloudflare (prod). Production refuses local-noop unless MUSHI_ALLOW_LOCAL_SANDBOX=1Verify — Playwright screenshot diff + step interpreter (navigate / click / type / press / select / assertText / waitFor / observe)Enterprise — Plugin marketplace + HMAC, audit ingest, region pinning, retention CRUD, Stripe metering, SAML SSO via Supabase Auth Admin API, **OIDC SSOSurface — LicenseApp — What it doesYou will need 4 environment variables: VITE_MUSHI_PROJECT_ID, VITE_MUSHI_API_KEY, ANTHROPIC_API_KEY, OPENAI_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
This sits in the browser automation group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Mushi Mushi's toolset — Catches, Output, Auto-fix and 8 more — is a fair guide to whether it matches your workflow. It is maintained by kensaurus; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
