LocalWP Agent Tools

A Local add-on that provides an MCP server and project context for AI-powered WordPress development. Works with Claude Code, Cursor, Windsurf, VS Code Copilot, and any MCP client.

What It Does

When you click "Enable" on a site in Local, the add-on:

1. Registers the site with the MCP server — a single HTTP server running in Local's main process that gives AI tools access to WP-CLI, error logs, configuration, and site management
2. Writes MCP config (.mcp.json, .cursor/mcp.json, etc.) — auto-configured with the correct HTTP endpoint for each agent
3. Generates project context (CLAUDE.md, .cursorrules, etc.) — site context including PHP/MySQL versions, active plugins, theme, and file structure
4. Updates .gitignore — so generated files aren't committed

Then open the site folder in your AI tool of choice and you're ready to go.

Architecture

The MCP server runs as a single HTTP server inside Local's Electron main process — no separate Node.js processes per site. Each site gets its own endpoint:

http://localhost:{port}/sites/{siteId}/mcp

The server uses the MCP Streamable HTTP transport. The port is stable across restarts (persisted at ~/.local-agent-tools/port, default 24842).

Sites remain registered even when stopped, so the MCP endpoint is always reachable. Tools that need running services (WP-CLI, database) return appropriate errors; file-based tools (config, logs, site info) work regardless. Config is refreshed on each tool call, so starting a site automatically makes database tools work without reconnecting.

Installation

From Source

git clone <repo-url> agent-tools
cd agent-tools
npm install --legacy-peer-deps
npm run build

Copy the built add-on to Local's add-ons directory:

# macOS
cp -r . ~/Library/Application\ Support/Local/addons/agent-tools/

# Install production dependencies in the installed location
cd ~/Library/Application\ Support/Local/addons/agent-tools/
npm install --production --ignore-scripts

# Then restart Local

Development

# Build the add-on
npm run build

# Watch for changes
npm run watch

After building, sync to the installed add-on:

cp -R lib/* ~/Library/Application\ Support/Local/addons/agent-tools/lib/

Then restart Local to pick up changes.
