JesusGarcia9009/lethe-engineering
MCP server Claude CodeCodexCursor +2
Context garbage collector for long-running LLM agents — offload and recall to save tokens (Claude Code & Codex via MCP). Runs locally from the lethe-llm-context Python package. Needs 1 environment variable to run.
MCP server Claude CodeCodexCursor +2
Vendor-neutral CLI and MCP server that verifies the token and cost savings AI-coding-agent context-reduction proxies (rtk, headroom) actually deliver, measured against a real 23-task labeled corpus with a local tokenizer instead of the proxy's own claimed. Runs locally from the tokentrust-cli npm package.
MCP server Claude CodeCodexCursor +2
Working memory for AI agents: digest-indexed episodes on a git shelf, recalled a section at a time. Runs locally from the memshelf-mcp Python package.
MCP server Claude CodeCodexCursor +2
Context window token analysis and budget management. Runs locally from the token-lens-mcp npm package.

MCP server Claude CodeCodexCursor +2
MCP orchestrator — connect unlimited Model Context Protocol servers through 8 meta-tools. Progressive tool discovery keeps your AI agent's context window small. Runs locally from the slop-mcp Python package.
MCP server Claude CodeCodexCursor +2
Resource-aware layer for Claude Code: feeds rate-limit and context headroom to the agent itself, so it plans work that fits the budget. Runs locally from the tokenroom npm package.
MCP server Claude CodeCodexCursor +2
MCP server "leptin-hlp" as configured in lionellau/leptin. Runs locally from the leptin-hlp Python package.
MCP server Claude CodeCodexCursor +2
MCP (Model Context Protocol) proxy/router that sits in front of a fleet of downstream MCP servers and exposes only a handful of meta-tools (searchtools, describetool, calltool, listservers) to the host instead of every downstream tool definition — cut. Runs locally from the @m8t-jacob/mcp-lens npm package.
MCP server Claude CodeCodexCursor +2
Fast, in-memory structured markdown knowledge base (.agent-kb/) with 2D neural graph visualization, live SSE activity stream, and MCP stdio integration. Runs locally from the @liulinnuha/lithium-kb npm package.
