> A token-saving MCP proxy for OpenClaw users. Cuts tool call payloads by 90%+ via lazy expansion.
Why
MCP tool calls often return thousands of tokens of HTML or JSON in a single response — but the model typically uses only 5% of it. The remaining 95% silently burns context window and increases cost. claw-tsaver sits between OpenClaw and your downstream MCP servers, intercepts oversized responses, and hands the model a compact preview + an on-demand handle instead.
How
Real measurement
| Test | Original tokens | Returned tokens | Saved |
|---|---|---|---|
| fetch Wikipedia "Tokenization (data security)" | 11,507 | 104 | **99.1%** |
Tested on OpenClaw + Claude Sonnet 4.6 + mcp-server-fetch, 2026-04-25.
Raw data: benchmarks/mvp-day1-fetch.jsonl.
Quick Start
1. Prerequisites
Install uv (one-time setup):
No claw-tsaver install needed — uvx will fetch and run it on demand.
2. Configure downstream MCP servers
Edit ~/.claw-tsaver/config.json (first run of claw-tsaver-mcp will auto-create a template):
3. Register with OpenClaw
Add this block at the top level of ~/.openclaw/openclaw.json:
Then restart OpenClaw gateway: openclaw gateway restart
Dashboard
Optional: a local web UI for real-time token savings stats.
Open in your browser.
Roadmap
- [x] **Module A**: lazy expansion proxy (this release)
- [x] **Module D**: local dashboard (this release)
- [ ] **Module B**: tool routing (auto-load only relevant MCPs per turn)
- [ ] **Module C**: conversation history compression (atomic fact cards)

🇨🇳 中文说明
什么是 claw-tsaver？
**claw-tsaver** 是一个为 OpenClaw 用户设计的 MCP 代理，通过懒加载扩展机制将工具调用的 token 消耗削减 **90%+**。
问题背景
MCP 工具调用（如 fetch、puppeteer）经常在单次响应中返回数千个 token 的 HTML 或 JSON，但模型通常只使用其中约 5% 的内容。剩余 95% 悄悄消耗上下文窗口并增加费用。
解决方案
claw-tsaver 作为 OpenClaw 与下游 MCP 服务器之间的代理：
1. 拦截过大的响应（超过可配置的 token 阈值）
