# Context Mode

> Context Mode is an MCP server plus hooks for Claude Code, Cursor, Gemini CLI, Copilot, Codex, OpenCode and other agents. It runs tool output in a sandbox and returns only the result, and logs session events to local SQLite so the agent can find them after compaction. Needs Node.js 22.5+ (or Bun) and an AI coding agent. It is source-available under the Elastic License 2.0, not open source: you may not offer it as a hosted service. The README says there is no telemetry. It does not replace a paid product.

## What it replaces
Nothing people pay for: a free tool, listed because people search for it.
