About this plugin
Context Mode helps Claude Code work with less raw data in its context window. It provides sandboxed code execution in 11 languages and stores project information in an FTS5 knowledge base, using BM25 ranking and intent-driven search to retrieve relevant results.
Use it for long coding sessions where tool output, large files or repeated searches would otherwise consume context. The MCP server also preserves session state and restores it after context compaction.
