Heuristic

Heuristic MCP adds smart code search to your editor or MCP client.

Requirements

• Node.js 18+
• npm (for global install)
• Internet access at least once to download the embedding model (if install-time download is skipped, it downloads on first run)
• 64-bit Node.js recommended for native ONNX performance; on Windows, install Microsoft Visual C++ 2015-2022 Redistributable (x64) if native bindings fail

Install

npm install -g @softerist/heuristic-mcp

Then enable it for your client:

heuristic-mcp --start

If your editor was already open, reload it once.

How It Works

1. The server scans your workspace and builds a searchable index of your code.
2. IDE AI models/MCP tools query that index using plain language so you can find relevant code quickly.
3. Results improve as your index stays up to date with project changes.

Basic Commands

heuristic-mcp --status
heuristic-mcp --logs
heuristic-mcp --stop

Use heuristic-mcp --status first if something looks off. Use heuristic-mcp --cache to see the cache status or file index progress.
