Summary
This is a cognitive toolkit that gives Claude structured reasoning patterns and memory primitives. Instead of just prompting differently, you get actual tools: thinking models like backtracking and symbolic abstraction, memory cells for state and episodic storage, and multi-agent patterns like debate councils. The Gateway tool routes requests to either direct execution or the Architect, which generates custom agent blueprints by combining these primitives. The Librarian exposes a browsable catalog of all available techniques. Useful when you need more than conversation history, like maintaining state across sessions, enforcing verification steps, or orchestrating multiple reasoning perspectives on complex problems.
Keep your Mac awake while Claude Code and 40+ AI agents run. Sleeps when they're idle.

The MCP Context Engineering Engine
Sutra is a Model Context Protocol (MCP) server that transforms how LLMs handle reasoning, memory, and orchestration. It provides a "Standard Library" of cognitive tools (Thinking Models), memory structures (Cells), and multi-agent patterns (Organs).
Installation
Using uv (Recommended)
uv tool install context-engineering-mcp
Using pip
pip install context-engineering-mcp
Configuration
Select your agent below and copy-paste the config.
Claude Desktop
Add to claude_desktop_config.json:
{
"mcpServers": {
"sutra": {
"command": "uv",
"args": ["tool", "run", "context-engineering-mcp"]
}
}
}
Claude Code
Run this in your terminal:
claude mcp add sutra uv tool run context-engineering-mcp
Aider
Run aider with the mcp flag:
aider --mcp "uv tool run context-engineering-mcp"
Or add to .aider.conf.yml:
mcp: ["uv tool run context-engineering-mcp"]
Gemini CLI
Add to ~/.gemini/settings.json:
{
"mcpServers": {
"sutra": {
"command": "uv",
"args": ["tool", "run", "context-engineering-mcp"]
}
}
}
Cursor / Windsurf
In MCP settings, add a new server:
- Name: Sutra
- Type: command
- Command:
uv tool run context-engineering-mcp
Codex
Add to your config (TOML):
[mcp_servers.sutra]
command = "uv"
args = ["tool", "run", "context-engineering-mcp"]
Core Features (v0.1.0)
1. The Gateway (Router)
Sutra automatically analyzes your request to decide the best strategy:
- YOLO Mode: For immediate tasks ("Fix this bug"), it routes to specific cognitive tools.
- Constructor Mode: For system design ("Build a bot"), it routes to the Architect.
2. The Architect
Generates blueprints for custom agents, combining:
- Thinking Models:
understand_question,verify_logic,backtracking,symbolic_abstract. - Memory Cells:
key_value(State),windowed(Short-term),episodic(Long-term). - Organs:
debate_council(Multi-perspective),research_synthesis(Deep Dive).
3. The Librarian
A manual discovery tool (get_technique_guide) that lets you or the agent browse the full catalog of Context Engineering techniques.
Development
Requirements: Python 3.10+, uv (optional but recommended).
- Clone the repo:
git clone https://github.com/4rgon4ut/sutra.git cd sutra - Install dependencies:
uv sync --all-extras # OR pip install -e ".[dev]" - Run tests:
