Agent-Corex - Intelligent Tool Selection for LLMs
Fast, accurate MCP tool retrieval engine with hybrid semantic + keyword ranking
Agent-Corex
Intelligent Tool Selection for LLM-Based Systems
Stop feeding your LLM tools it doesn’t need. Agent-Corex intelligently selects the top N most relevant tools in milliseconds using hybrid semantic + keyword ranking.
Install
Homebrew (macOS / Linux — no Python required)
brew tap ankitpro/agent-corex
brew install agent-corex
Direct binary (no Python required)
| Platform | Command |
|---|---|
| macOS arm64 (M1/M2/M3 + Intel via Rosetta) | curl -fsSL https://github.com/ankitpro/agent-corex/releases/latest/download/agent-corex-macos-arm64 -o /usr/local/bin/agent-corex && chmod +x /usr/local/bin/agent-corex |
| Linux x86_64 | curl -fsSL https://github.com/ankitpro/agent-corex/releases/latest/download/agent-corex-linux-x86_64 -o /usr/local/bin/agent-corex && chmod +x /usr/local/bin/agent-corex |
| Windows x86_64 | Download .exe |
pip (Python 3.8+)
pip install agent-corex
The Problem We Solve
When building LLM agents with access to hundreds of tools, including all of them in the system prompt causes:
- Context Bloat — 30K+ tokens per request
- Higher Costs — 68% more expensive per query
- Slower Inference — 4–5x latency increase
- Model Confusion — LLM picks random tools when overwhelmed
Agent-Corex solves this by intelligently selecting only the 5–10 tools your LLM actually needs.
Quick Stats
| Metric | Impact |
|---|---|
| Token Reduction | 50–75% fewer tokens |
| Speed Improvement | 3–5x faster inference |
| Cost Savings | 68% reduction per query |
| Selection Accuracy | 92% precision (top-5) |
One-Command Setup
Connect Agent-CoreX to Claude Desktop, Cursor, VS Code, or VS Code Insiders:
agent-corex login --key acx_your_key
agent-corex init
Agent-CoreX detects your installed tools, backs up their configs, and safely merges the gateway entry — existing MCP servers are never touched.
