Context Mode

Context Mode is an MCP plugin that keeps raw tool output out of an AI coding agent's context window. It intercepts large results from commands, searches and file reads before they reach the conversation, stores the raw data in a local full text search index, and lets the agent query it when needed, so the same output is not resent to the model on every turn. The plugin is for developers whose agents burn through context on long sessions. It runs entirely on the local machine with no cloud, telemetry or account, and works across 17 adapters including Claude Code, Cursor, GitHub Copilot, Codex, Gemini CLI, JetBrains Copilot, Antigravity CLI and Kiro. The vendor states it saves up to 98 percent of context per session. For engineering organizations, Context Mode Platform adds an opt in layer on top of the same plugin that forwards structural events, such as tool names and file paths, but never source code or prompt content. Its first solution, Context Mode Insight, runs pattern analysis over those events to report productive rates, retry waste and blockers, with views narrowed for CTOs, engineering managers, individual contributors, security leads, FinOps and DevOps. The plugin is free and installs from npm under the Elastic License 2.0. Context Mode Platform, including Insight, costs $20 per seat per month and is self serve. Because Insight depends on events the plugin already captures, organizations already running the plugin can enable it with a single opt in switch.
