Install Skills
Context Engine ships AI agent skills that teach your coding assistant how to use 30+ MCP tools for semantic search, symbol graph navigation, memory, and more.
Claude Code / Claude Desktop
Recommended: Install natively from the public GitHub repo:
# Add the marketplace (one-time)
/plugin marketplace add Context-Engine-AI/Context-Engine
# Install the skill
/plugin install context-engine
This pulls the skill directly from GitHub and auto-loads MCP tool guidance into your session.
Alternatively, copy the rules file manually:
cp -r skills/context-engine/ your-project/.claude/
Cursor
Context Engine rules are included in .cursorrules at the root of your workspace. Cursor picks this up automatically when the file is present.
# Copy to your project root
cp .cursorrules your-project/.cursorrules
Codex (OpenAI)
Recommended: Install natively using the built-in skill installer — just ask Codex:
"Install the context-engine skill from https://github.com/Context-Engine-AI/Context-Engine"
Codex will pull .codex/skills/context-engine/ (including SKILL.md and reference docs) into ~/.codex/skills/ automatically.
Or install manually:
cp -r .codex/skills/context-engine/ ~/.codex/skills/context-engine/
Windsurf
cp -r .codex/skills/ your-project/.codex/skills/
Augment Code
cp -r .augment/ your-project/.augment/
Gemini
cp GEMINI.md your-project/GEMINI.md
Any Other Assistant
The core skill file works with any AI assistant that supports custom instructions:
cp skills/context-engine/SKILL.md your-project/
Then tell your assistant: "Read SKILL.md for instructions on using Context Engine MCP tools."
CLI Setup (No VS Code)
If you use Claude Code, Codex, or another terminal-based MCP client, install the MCP bridge to connect your codebase to Context Engine without VS Code:
npm install -g @context-engine-bridge/context-engine-mcp-bridge
Quick start
# Authenticate, index your codebase, and start watching for changes
ctxce connect <your-api-key> --workspace /path/to/repo
# Run as a background daemon (recommended)
ctxce connect <your-api-key> --workspace /path/to/repo --daemon
Daemon management
ctxce status # Check if the daemon is running
ctxce stop # Stop the background daemon
Connect flags
| Flag | Alias | Description |
|---|---|---|
--workspace |
-w |
Workspace root (default: cwd) |
--daemon |
-d, --bg |
Run as background daemon |
--interval <sec> |
File watch interval in seconds (default: 30) | |
--no-watch |
--once |
Index once, don't watch for changes |
--skip-index |
--auth-only |
Authenticate only, skip initial index |
Wire up the MCP server
Once connected, point your MCP client at the bridge:
# stdio mode (for Claude Code, Codex, etc.)
ctxce mcp-serve --workspace /path/to/repo
# HTTP mode (for clients that speak HTTP)
ctxce mcp-http-serve --workspace /path/to/repo --port 30810
The daemon and MCP server share auth via ~/.ctxce/auth.json. Logs are at ~/.context-engine/daemon.log.
