An MCP server that sandboxes tool output, persists session memory in SQLite, and enforces context routing across 17 AI coding platforms.

Context Mode works by combining Sandboxed Tool Output: Tool results are executed and filtered outside the context window so only the answer returns to the model, cutting a 315 KB payload to about 5.4 KB., SQLite Session Continuity: File edits, git operations, tasks, errors, and user decisions are tracked in SQLite so the agent can resume exactly where it left off after a compaction., FTS5 + BM25 Retrieval: Session events are indexed into SQLite FTS5 and retrieved by BM25 relevance rather than being replayed wholesale into context., Think-in-Code Routing: A mandatory paradigm across supported clients that has the model write a script to compute results instead of reading files into context, replacing many tool calls with one., Hook-Based Enforcement: On Claude Code the plugin registers PreToolUse, PostToolUse, UserPromptSubmit, PreCompact, SessionStart, and Stop hooks so routing is injected at runtime with no file written to your project. to help users with Long Coding Sessions: Keep a multi-hour agent session usable by preventing large Playwright snapshots, issue lists, and logs from consuming the context window., Surviving Compaction: Resume work after the conversation compacts without the agent forgetting which files it was editing or what task was in progress., Large Log and Data Analysis: Have the agent script the analysis over a 45 KB access log rather than reading it into context to reason over it manually., Multi-Platform Agent Setups: Standardize context routing across Claude Code, Cursor, and the other supported clients so behavior is consistent regardless of tool., Cost Reduction: Cut token spend on agent-heavy workflows by removing raw tool payloads from prompts..
