GIVE YOUR AI AGENT THE ABILITY
TO ASK ANOTHER AI TO KILL ITS PLAN
@scopecreeper/mcpis now on npm. It's a Model Context Protocol server that exposes eight Scope Creeper tools to Claude Code (or any MCP-speaking client): scan, kill, inbox, history, scope, patterns, audit, and shippable.
The point: Claude is sycophantic by default. Ask it for a plan and you get a plan. Scope Creeper is the opposite — its kill tool returns a brutally honest one-page autopsy arguing why a project should NOT be built, with dated cutoff signals and a one-line eulogy. Install the MCP and your agent gains an adversarial second opinion it can invoke before writing a single line of code.
▸ Install in 30 seconds
(Optional) generate an API key at scopecreeper.ai/account. Without a key the free tier still works — keys just identify your Pro entitlement.

▸ Eight tools
scope_creeper_scan(payload) — quick delusion score (0-100) + tier + verdict + 3-5 creep dimensions. Free tier.
scope_creeper_kill(plan)— markdown autopsy with sunk-cost framing, dated cutoff signals, "what to build instead", and a one-line eulogy. Free tier. This is the one that matters.
scope_creeper_inbox(drain?)— reads pending drift events from the local daemon's inbox. Pass drain: true to mark them read. Free tier.
scope_creeper_history(repo?, area?, sinceDays?)— query your past drift decisions. Useful for "have I rejected this before?" Free tier.
scope_creeper_scope(repoPath) — reads .scopecreeper.md+ the decision diary so Claude can ground recommendations in what you've already declared. Free tier.
scope_creeper_patterns(windowDays?) — surfaces behavioral patterns: what you keep expanding, what you keep avoiding, which repos are chronically in ABYSS. Free tier.
scope_creeper_audit(repo) — deep code audit on a public GitHub repo: grep heuristics (secrets, TODO density, dead tests, dep age) + LLM narrative with file:line evidence. Pro tier ($9/mo).
scope_creeper_shippable(plan) — 1-page PRD with a named stack, V0 scope (3-5 bullets), 3-4 acceptance criteria, and 4-6 paste-runnable shell commands for the first 30 minutes of work. Pro tier ($9/mo).
▸ The workflow
Before any big build, ask Claude Code:
> Use scope-creeper to KILL this plan before we start: > "Build a Notion competitor with AI, calendar, CRM, voice notes."
Claude calls scope_creeper_kill and pastes back the autopsy. If the autopsy is convincing, you walked away cheap. If the plan survives the autopsy, ask for scope_creeper_shippable and get a paste-runnable v0 spec.
▸ Why we built it
Scope Creeper started as a web tool. The web is good for discovery and the "score my repo" moment, but the actual decision to start building usually happens inside a chat — exactly where Claude Code lives. The MCP puts the adversarial second opinion at the moment of decision, not after.
The whole package is 4.5KB on the wire, zero external dependencies beyond the official MCP SDK, no telemetry, and the API key (if you choose to use one) only authenticates — we never see your plan text outside the LLM call that produces the artifact.
▸ Try it free, no key
Six tools work without authentication (subject to a per-IP rate limit): scan, kill, inbox, history, scope, and patterns. The Pro tier ($9/mo) unlocks audit and shippable, plus the web app (share links, projects, leaderboard).
