Context Mode: MCP server that cuts AI coding agents' context waste by 98%
MCP server + hooks for AI coding agents that sandboxes tool output out of the context window, persists session memory in SQLite, and enforces routing across 17 platforms (Claude Code, Cursor, Copilot, Gemini CLI, Codex, and more).
Why it matters
The only context optimizer that works across 17 coding-agent platforms via MCP + hooks, with measured 98% context reduction (315 KB becomes 5.4 KB) and session continuity through conversation compaction.
What you could build with it
An engineering team running long Claude Code or Cursor sessions could deploy Context Mode's MCP server to sandbox tool output and persist session memory in SQLite, so multi-hour refactors no longer burn the context window on raw logs and forgotten progress.
Does it hold up?
Mature for its size: 26k+ stars, 195 releases, public benchmarks (BENCHMARK.md) and a /ctx-doctor diagnostic; the 98% reduction figure is the author's own benchmark, and independent before/after verification beyond star volume is thin.
