README
1Install 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 <path> | -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.
For full bridge documentation, see Context-Engine-MCP-Bridge.
What Do the Skills Do?
The skills teach your AI assistant to:
- Use
searchas the default tool — auto-routes queries to the best backend (semantic search, Q&A, symbol graph, tests, config) - Navigate code with
symbol_graph— find callers, callees, definitions, importers, subclasses - Run batch queries —
batch_search,batch_symbol_graph,batch_graph_queryfor 75%+ token savings - Store and recall knowledge —
memory_storeandmemory_findfor persistent context across sessions - Trace cross-repo flows —
cross_repo_searchwith boundary tracing for multi-repo codebases - Find structural patterns —
pattern_searchfor retry loops, error handling, singletons across languages - Search git history —
search_commits_forandchange_history_for_path
See skills/context-engine/SKILL.md for the complete tool reference.
Getting Started
- Sign up at context-engine.ai
- Connect your codebase — choose one:
- VS Code — install the Context Engine Uploader extension
- CLI —
npm i -g @context-engine-bridge/context-engine-mcp-bridge && ctxce connect <api-key> --daemon
- Install the skill for your AI assistant (see Install Skills above)
- Start searching — your assistant now has access to all 30+ MCP tools

context-engine is a Claude Code plugin with 1 hand-picked skill for development work, indexed on Flowy. Install it with the command on its page. It includes context-engine. Its skills do not fire on their own yet. Request auto-invocation to have Flowy route them as you prompt. Free and open source.
- What is context-engine?
- Context-Engine MCP - Agentic Context Compression Suite
- How do I install context-engine?
- Run these in Claude Code: /plugin marketplace add Context-Engine-AI/Context-Engine then /plugin install context-engine@context-engine-skills. Then prompt normally.
- Does context-engine auto-invoke its skills?
- Not yet. It is indexed on Flowy as a plain plugin. Request auto-invocation on its page and Flowy will route its skills for you as you prompt.
- Is context-engine free?
- Yes. Flowy is free and open source, with nothing gated. You can read every skill in full before you install.
