Context Mode is an MCP server and hook-based system that optimizes AI coding agent context windows by sandboxing tool outputs and providing persistent session memory.
It reduces context consumption by up to 98% by keeping raw data out of the conversation and using a local SQLite FTS5 database for intelligent retrieval.

Free and source-available under the Elastic License 2.0 (ELv2).
Best for
Long-running coding sessions involving large logs, browser automation, or complex repository research that frequently hit context limits.
Not ideal for
Short, simple coding tasks where context limits are not reached, or Windows environments where some orphan/hang bugs are still being addressed.
An essential tool for power users of AI coding agents who need to extend session longevity, though users should be aware of its ELv2 license and minor stability caveats on Windows.
Recent releases have focused on platform-specific hook parity, self-injection guards for session resumes, and improved version-check reliability for long-running sessions.
