An MCP server wrapper for reducing tokens consumed by MCP tools, available in typescript, python, and rust

A high-performance, token-efficient Model Context Protocol (MCP) gateway proxy. Avoids context bloat and eliminates multi-turn tool discovery latency by intercepting prompts and semantically injecting only the exact schemas the LLM needs.

Compress all connected MCP into a single router MCP and save up to 99% on tokens

A simple, secure MCP-to-OpenAPI proxy server

A zero-dependency MCP and Local tool gateway: host your own tools in any language, forward and curate tools from other MCP servers, expose them leanly to cut agent token cost, gate every call through your own policy hooks before it runs, create your own MCP servers easily with zero code - and wrap any MCP server so it speaks both protocol eras! :)

The most compatible MCP CLI client. Supports: tools, resources, prompts, completions, async tasks, skills, stdio and streamable HTTP (MCP 2026-07-28 and 2025-11-25), persistent sessions, OAuth 2.1 with DCR, CIMD, client credentials, and ID-JAG, OS keychain, --json for code mode, grep for tool discovery, proxy for AI sandboxes, x402, and more.
