SuperLeanAI is a token efficiency company — full stop. AI labs have every economic incentive to maximize your token usage; nobody was pushing back until we did. We debloat, trim, and minify every request your agent sends — built-in tools, MCP servers, Skills, all of it — so you spend as few tokens as possible. We only make money when you save tokens.
Also known as prompt compression, context compression, or prompt debloating — whatever you call it, we do it for every request your coding agent sends.
Same task, same agent — side by side, with and without SuperLean.
Agents like Claude Code send lots of information (10+ tool definitions, plus whatever your MCP servers and Skills add) on every LLM call. The labs have no incentive to make them short — token efficiency is our entire business.

SuperLeanAI is a transparent HTTP proxy. Point your agent's BASE_URL to api.superleanai.com (e.g. via ANTHROPIC_BASE_URL) and you're done.
Verbose, multi-paragraph tool descriptions — from built-in tools, MCP servers, and Skills alike — are summarized to a single sentence. The model still understands the tool — it just costs 92% less to say so.
Block tools, MCP servers, or Skills your agent doesn't really need (e.g. NotebookEdit, Grep, an unused MCP server). Or use agressive bash_only mode: strip everything down to just Bash, Read, and Edit — the minimum set for most coding tasks.
Override the model on the fly — swap Opus for Sonnet during bulk tasks, or route different profiles to cheaper models without touching agent code.
Built as a production-grade proxy with JWT auth, per-session stats, and live savings.
Every session gets live stats: original tool bytes, debloated bytes, total traffic, and percentage saved. Know exactly what you're not paying for.
MCP servers and Skills are often the biggest source of bloat — every connected MCP tool schema and every loaded Skill's instructions ship on every call. Debloated the same way as built-in tools, transparently.
Route to OpenRouter, Google Gemini (via googleapis), Groq, or Together AI. Configure named profiles — groq, googleapis_minimal — with different strategies per use case.
Every request is saved to disk as JSON. Replay, audit, or analyze your agent's traffic. Tool calls from the response are also captured for future debloating.
Speaks the Anthropic /v1/messages API. Works with Claude Code, custom agents, any client targeting the Anthropic SDK. No code changes required.

Straight answers to how this actually works.
Prompt compression — also called context compression or prompt debloating — is shrinking the text an LLM API call sends (tool definitions, MCP server schemas, Skills instructions, system prompts, history) while keeping its meaning, so each request costs fewer tokens.
All of it. MCP servers and Skills often add more tokens per request than an agent's built-in tools, since every MCP tool schema and every loaded Skill's instructions go out on every call. SuperLeanAI debloats built-in tools, MCP servers, and Skills the same way, transparently.
SuperLeanAI is a transparent HTTP proxy purpose-built for AI coding agents. It debloats verbose tool definitions, MCP server schemas, and Skills instructions, filters what's unused, and trims context on every request with zero code changes — point your agent's base URL at the proxy and it works.
No. Verbose descriptions are summarized to their essential meaning, not truncated, so the model still understands every tool, MCP server, and Skill — it just costs far fewer tokens to say so.
Claude Code, Codex CLI, GitHub Copilot CLI, and Cline today — anything that speaks the Anthropic or OpenAI message APIs works out of the box.
Our incentives are completely aligned with yours. We take a small cut of the savings — if you don't save, you don't pay. Crystal clear, no subscription traps.
