Tool Safety75

Unverified: 1 category

A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

MCP tools · 3 exposed · ~881 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
review_flow ~331

Push a FLOW-ORDERED code review to Anti-Vibe: the human walks the change in runtime execution order (like a sequence diagram), not file-by-file. Send ONLY the traversal STRUCTURE — never the diff text. Anti-Vibe resolves each hunk by running `git diff` in the repo and matching your locators. Order `flow` stops top→bottom in call order (entry → handler → service → effect); put models/schemas/contracts/types in `foundation` and list them bottom→up. Each stop maps to a FILE — the reviewer steps through all of that file's hunks one at a time. `locator` is an OPTIONAL hint (exact `hunkHeader` "@@ -a,b +c,d @@ ..." or `lineRange`) that just sets the match-confidence badge. Give each stop a one-line summary. For unchanged connective steps (a dispatcher/existing handler the flow passes through), add a stop with `context: true` and no locator so the sequence reads continuously. When a stop's file has several hunks, add `hunkFlow` to order them for reading in execution order (behavior change before plumbing) with a one-line note per hunk.

review_markdown ~263

Send markdown to the Anti-Vibe reader so a human can review it without fatigue, moving heading-by-heading and optionally speed-reading each section. Provide your output as well-structured Markdown — use `#`/`##`/`###` headings to break it into sections (Anti-Vibe navigates by heading), plus normal Markdown for lists, tables, code blocks and emphasis. Pass the full content in `markdown`. For CODE REVIEW / diff content: one `###` heading per file, and NEVER paste a whole file or diff as a single fenced block — each fenced block is one atomic step in the reader, so an oversized block becomes an unreviewable wall. Split code into small fenced blocks (one function or one logical hunk, ~15 lines each) and precede each block with one line of prose saying WHY that piece exists. This applies doubly to NEW files: present them one function/section at a time, never verbatim top-to-bottom. Opens the Anti-Vibe tab on first use and live-updates it on later calls.

rsvpify_markdown ~287

Send an agent response to the Anti-Vibe reader OPTIMIZED for RSVP speed-reading, where one word is flashed at a time. Because raw agent output reads badly word-by-word, YOU must rewrite the content before passing it in `markdown`: (1) Rephrase into flowing, natural prose — full sentences, minimal symbols, no bullet fragments or telegraphic notes; write it as if it were read aloud. (2) Replace every code block with a short PROSE SUMMARY of what the code does (e.g. "A function that validates the token expiry using a strict less-than check."). Do not paste raw code into the prose — summarize it. (3) Keep `#`/`##` headings as the section spine. (4) When a TABLE or other structured element is essential to keep verbatim, include it as a normal Markdown table/code block — Anti-Vibe renders these as atomic blocks and AUTO-PAUSES the RSVP stream on them so the reader stops and studies them, then resumes. Use this tool for content a human will speed-read; use `review_markdown` to preserve the original code and structure verbatim.

Is the Anti-Vibe MCP server safe to use?

Anti-Vibe scores 67 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 17 October 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the Anti-Vibe MCP server expose?

Anti-Vibe exposes 3 tools: review_markdown, rsvpify_markdown, review_flow. Their descriptions and schemas cost roughly 881 tokens of context every time the server is loaded.

Is the Anti-Vibe MCP server still maintained?

Anti-Vibe is still listed as active in the MCP registry. We last reached this channel on 17 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
