MCP server that pushes agent output into the Anti-Vibe reader — for people who actually read the diff instead of vibe-merging it. Read LLM/agent output one sentence at a time, skim it heading by heading, or speed-read it via RSVP.

It runs a tiny loopback bridge that serves the Anti-Vibe web app from its own origin and live-pushes documents to the open tab over Server-Sent Events, so no copy-paste is needed.

Install

Claude Code:

claude mcp add anti-vibe -- npx -y anti-vibe-mcp

Any other MCP client (Claude Desktop claude_desktop_config.json, Cursor mcp.json):

{
  "mcpServers": {
    "anti-vibe": {
      "command": "npx",
      "args": ["-y", "anti-vibe-mcp"],
      "env": { "ANTIVIBE_MCP_PORT": "7777" }
    }
  }
}

Then ask your agent to "send this to Anti-Vibe for review". The first call opens http://127.0.0.1:7777; later calls go to the same tab. If you're in another window, the tab switches to the new document; if you're reading in it, the new document waits in the Documents list (l).

Tools

review_markdown — { markdown, title? } → { documentId, sectionCount, wordCount, url }. Sends your Markdown to the reader as-is (code blocks, tables and structure preserved). Use when the human should review the original output verbatim.
rsvpify_markdown — { markdown, title? } → { documentId, sectionCount, wordCount, url }. Sends output optimized for RSVP speed-reading. Before calling, the agent rewrites the content: rephrase into flowing prose, replace each code block with a short prose summary of what it does, and keep tables/other structured blocks verbatim (Anti-Vibe auto-pauses the RSVP stream on them so the reader stops, studies, then resumes).
review_flow (in development) — { stops, title?, repoPath?, diffBase? } → { documentId, stopCount, resolvedCount, url }. Pushes a flow-ordered code review: the human walks a change in runtime execution order (like a sequence diagram), not file-by-file. The agent sends only the traversal structure — stops tagged flow / foundation, wired by callsTo, with optional per-hunk reading order (hunkFlow) — never the diff text. The server runs git diff in the repo and resolves each stop to its real hunks. Use diffBase to target staged (--cached), a commit (HEAD~1..HEAD), or a branch (main...HEAD).

Config

ANTIVIBE_MCP_PORT — bridge port and review URL (default 7777, loopback only).
ANTIVIBE_DIST_DIR — override the served web-app directory (advanced).
