For power users of Claude Code, Cursor, Codex, Gemini, Amp, and any MCP agent who are tired of fixing the same mistakes every session.
Every mistake makes your agent stronger. ThumbGate turns thumbs-up/down feedback into hard gates that block bad actions before they execute. Think of it as an immune system for your AI agent — it learns from your corrections, distills vague signals from conversation context, and enforces lessons automatically. More errors = stronger gates. The safety net for vibe coding that gets more valuable the more chaos it encounters.
Claude Code, Claw-code, Codex, Gemini CLI, Amp, and OpenCode all use the same gateway and memory model. Any MCP-compatible agent gets pre-action gates, feedback memory, and enforcement out of the box.
One command install. No build step, no cloud account. Grab the .mcpb bundle or run npx thumbgate init --claude-desktop.
Cursor ships with a bundled marketplace plugin. VS Code works when you run an MCP-compatible agent inside it.
Type /thumbgate in any Claude Code session. Auto-triggers on "gate", "feedback", "block mistake". Free skill with Pro upgrade path built in.
Why thumbs-up/down feedback and pre-action gates solve repeated mistakes faster than a manual spec-authoring loop.
Mem0 remembers context. ThumbGate enforces behavior. Why retrieval alone is not enough when your agent keeps repeating the same mistakes.
The core concept explained in plain language: how thumbs up, thumbs down, and runtime enforcement work together to prevent repeated failures.
Why structured feedback memory matters more when it becomes a live gate that blocks your agent from repeating mistakes.
Give 👍 or 👎 on your AI agent's actions. Feedback is stored in a SQLite+FTS5 lesson DB. If the signal is vague, ThumbGate can distill it from the recent conversation window and failed tool call before promotion. Example: you 👎 a risky migration → it auto-promotes to a "never run DROP on prod" gate.
Repeated failures auto-promote into prevention rules. Thompson Sampling adapts which rules fire, and the reflector lane can propose a reusable rule from the same transcript so high-risk patterns get stricter enforcement while low-risk ones stay relaxed.
Rules become Pre-Action Gates that block your agent before it repeats the same mistake. Your agent can't force-push, skip tests, or repeat a refactor you already rejected. No more fix-loops.
Every agent mistake becomes a prevention rule. Every thumbs-down becomes a gate. The more your agents fail, the more ThumbGate learns. Fragile systems break under chaos — ThumbGate feeds on it.
One developer's thumbs-down becomes the whole team's protection. Lessons compound across agents, sessions, and projects. Your 100th agent inherits everything the first 99 learned.
CISOs fear agent chaos. ThumbGate turns that chaos into structured audit trails, per-agent governance scores, PII scanning, and credential attestation. Compliance officers get a single dashboard, not scattered logs.
Gate reasoning chains show exactly WHY an action was blocked: pattern match, evidence, fire count. No hidden decisions.
MCP tools call real enforcement — gates physically block tool calls, not ask the agent nicely. External system, not prompt tricks.
Every gate decision includes step-by-step reasoning. Thompson Sampling confidence tiers tell you when to trust the model vs fall back to rules.
Audit trail records every allow/deny/warn. Repeated failures auto-promote to gates. Org dashboard shows all agents across your team.
Feedback sessions let you open, append, and finalize one linked correction instead of spraying follow-up notes across separate records. Better lessons, less operator friction.
Installable best-practice rules for Stripe, Railway, database migrations. Auto-match by task context. 100% eval pass rate with packs vs 0% without.
P50/P90/P95 latency and success rate per tool. Drill from gateway health down to the exact tool causing issues.
Define thresholds for success rate and latency. Breach triggers webhook alerts to Slack, Teams, or Discord automatically.
Tracks authorized vs failed access. Moving-average spike detection flags per-agent abuse. Security governance on autopilot.
$0.10 per blocked mistake (Pro). Minimum $19/mo floor. You pay for value delivered, not seats warmed.
Push Slack/Teams/Discord summary at 9am. Weekly stats export for build-in-public content. Check in once a day, not babysit.
L1 metadata at startup (27 tokens). L2 rules on activation. L3 reference files on demand. Agents load only what they need.
Agent auto-generates new skill packs from recurring failures. Lessons become NEVER/ALWAYS rules. No manual curation needed.
Credential attestation per tool call. Privilege escalation detection against MCP profiles. Dependency gate blocks supply chain attacks.
Before a background agent opens a PR, check its failure history. Agents with >50% fail rate get blocked. Protected branches get extra scrutiny.
CI pass/fail auto-generates structured feedback. No human in the loop. The agent learns from every merge and every rejection.
Per-agent pass rates, gate blocks, run types, blast radius warnings. Know which agents are reliable and which need guardrails.
For solo devs experimenting with gates on one machine.
For individual operators who want a personal local dashboard with proof-ready exports.
Founder pricing — preserved $49 one-time founder link for early buyers who still want that path.
Mem0 Pro: $249/mo. ThumbGate Pro: $19/mo.
For teams running multiple agents across shared repos who need one lesson to protect everyone.
Hosted team rollout starts with the workflow sprint intake so we scope the shared workflow honestly.
The recurring value is shared enforcement. Start with one workflow, one owner, and one blocker. The hosted intake gives us a proof-backed path into the shared lesson DB, org dashboard, and team-wide gate rollout.

🧪 Thompson Sampling
Confidence tiers (none/low/medium/high) tell you when to trust the model vs fall back to rules. No guessing.
🪞 History-Aware Lessons
When a thumbs signal is vague, ThumbGate can reuse the last ~10 messages plus the failed tool call, propose what went wrong, and turn that into one linked lesson instead of a dead-end note.
