Common questions

Is SuperCompress safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: SUPERCOMPRESS_API_KEY

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.5.38) reached the registry 34 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

SuperCompress

SuperCompress v2 — cut ~64% of LLM input tokens for coding agents, without losing the answer.

~400M Neural Keep on the SuperCompress API scores bulky context (files, logs, tool dumps, pastes) against the current question and drops the rest. Your ask stays intact. This package wires Cursor / Claude Code / Codex / 40+ harnesses into that API via MCP + hooks.

Website · Benchmarks · Playground · Docs

Install

npm install -g supercompress-proxy

Requires Node.js 18+.

Quick start (recommended)

One command links your account and auto-adds MCP + hooks across 40+ harnesses (25+ get a native auto MCP plugin — Cursor, Claude Code, Codex, Goose, Zed, OpenCode, fx, Hermes, OpenClaw, Grok Build, Grok Bot (hosted MCP URL), Gemini, Windsurf, Continue, and more):

supercompress setup

supercompress doctor

Then restart your agent so integrations reload. That’s it.

Re-detect later (new agent installed, etc.):

supercompress plugin

supercompress agents supercompress doctor

Any other agent (custom harness, closed-source, DIY):

supercompress agents connect

That prints a stdio MCP snippet and writes an Agent Plugins 1.0 pack you can drop into any compatible client.

Benchmarks

How it works

Your agent ──→ SuperCompress (hooks / MCP) ──→ smaller context ──→ model

↑ query stays whole; only context is compressed

You ask a question (never rewritten).
Large context is scored against that question.
Evidence-critical lines stay in original wording; filler drops.
You pay for fewer input tokens.

Commands

Command	What it does
`supercompress` / `tui`	Interactive paper-branded UI (default in a TTY; Bun)
`supercompress setup`	Recommended — link account, detect agents, install MCP + hooks
`supercompress plugin`	Refresh agent integrations anytime
`supercompress doctor`	Per-harness health matrix (account / MCP / hooks)
`supercompress agents`	40+ catalog — auto-plugin vs recipe/connect
`supercompress start` / `stop` / `status`	Optional local proxy (`setup --proxy`)
`supercompress usage`	Plan, quota, savings (`--json` ok)
`supercompress limits`	Provider rate-limit runway — 5h / weekly windows (`--json` for agents)
`supercompress uninstall`	Remove configs under `~/.supercompress`

Optional localhost API proxy (base-URL rewrite) if you explicitly need it:

supercompress setup --proxy

supercompress start

Then point OpenAI/Anthropic-compatible clients at http://localhost:8080/v1.

MCP

setup / plugin registers the MCP server on every detected host. You can also run it directly:

supercompress-mcp

Manual registration:

"mcpServers": { "supercompress": { "command": "supercompress-mcp" } } }

Tool	Purpose
`compress_context`	Compress bulky context for a query
`connect_account`	Link this install to your dashboard
`usage_summary`	Savings for the connected account
`runway_check`	Provider rate-limit runway (local, no account needed)

Runway (rate limits)

supercompress limits --json / MCP runway_check tell the agent how much provider quota is left and what to do with it. Built from limitcheck, extended to every harness SuperCompress plugs into. Runway runs locally, inside this package; your usage data never goes through the hosted API, and the hosted MCP has no runway tool. Each check (limits status or runway_check, not the statusline) sends one anonymous count to the public total at limitcheck.supercompress.dev: just the verdict (go / land / pace / wait / unknown) and cli or mcp. No ids, usage numbers, prompts or paths. Opt out with SUPERCOMPRESS_TELEMETRY=0, DO_NOT_TRACK=1 or SUPERCOMPRESS_RUNWAY=0. setup / plugin install it automatically: they add the runway rule to every agent's instructions and skill, register runway_check on the local MCP, copy a standalone runtime to ~/.supercompress/runway/, and connect Claude Code's statusline. uninstall reverses all of it.

Source	Harnesses
`~/.codex/sessions` rate-limit events (zero config)	Codex
Statusline tee, wired by `setup` (or `supercompress limits connect claude-code`). Your own statusline keeps working unchanged	Claude Code
Upstream rate-limit headers seen by the local proxy (Anthropic, OpenAI, xAI, OpenRouter, Codex)	Any harness routed through `localhost:8080` (Aider, Continue, Cline, OpenCode, Goose, …)
`supercompress limits ingest --provider` (stdin JSON) / `SUPERCOMPRESS_LIMITS_SNAPSHOT` / `LIMITCHECK_SNAPSHOT`	Anything else (Cursor, Windsurf, Grok Build, Gemini CLI, custom hooks)

Actions: go (with scope), land (keep working, checkpoint before each step), pace (balanced policy only), wait (actually exhausted — waitMinutes, alternatives), unknown (no source; never invented).

The default max policy uses a 5h window all the way to the provider's cutoff instead of stopping at a fixed 10% floor: short windows reset on their own, so unused quota is wasted. Weekly/monthly windows are judged by pace (remaining % vs time left). --policy conservative keeps limitcheck's 25% / 10% thresholds. In a seeded simulation (node test/runway-sim.js) max uses 100% of a binding 5h window vs 91.5%, for +7.8% completed steps, and checkpoints before 59 of 60 cutoffs. SUPERCOMPRESS_RUNWAY=0 stops setup from touching the statusline and disables proxy header capture. Only rate-limit numbers are stored (~/.supercompress/limits/), never prompts or responses.

Account & pricing

1M tokens/month free, then $0.10 / 1M from the dashboard.

Privacy

Hooks / MCP run on your machine. Provider API keys stay with your agent. Context text is sent to the SuperCompress API so the hosted compiler can compress it.
