Shell Hook
Intercepts git, npm, cargo, docker, kubectl, pip, go, tsc, and 95+ more commands. Compresses output by 60–90%.
Universal Compatibility
Works with everyAI coding tool.
One install. One setup command. LeanCTX adds context engineering to every AI tool that uses MCP, and even those that don’t, through shell-hook compression.
81 MCP tools + shell hook context layer
Full MCP Support
Supported agents share the same local context layer, setup workflow, and shell compression.

One install. Every AI tool.
No MCP? No problem.
Shell Hook Only
Tools that don't support MCP still benefit from LeanCTX. The shell hook intercepts CLI commands (git, npm, cargo, docker, kubectl, ls, find, and 95+ more) and compresses their output before the AI sees it.
MCP Server
81 specialized tools: ctx_read, ctx_search, ctx_graph, ctx_intent, ctx_session, ctx_task, ctx_cost, and 74 more. Intent-aware compression, session memory, context routing, multi-agent handoffs, knowledge graphs.
Zero manual config
How Setup Works
Detects your shell
Finds zsh, bash, or fish and installs the shell hook that intercepts CLI commands.
Finds AI tools
Scans for Cursor, Claude Code, Copilot, Windsurf, Pi, Cline, Zed, and others. Configures MCP for each.
Writes MCP config
Creates the correct JSON config for each tool. No manual editing required.

Built on an open standard.
MCP (Model Context Protocol) is the open standard for connecting AI tools to external capabilities. Any future tool that supports MCP will work with LeanCTX automatically - no updates needed.
One binary. One protocol. Every AI tool.
Works with yourtools. Today.
One install, one <code>lean-ctx setup</code>, and every AI tool you use gets the same context engineering. No per-tool configuration.
