Context Mode

Context Mode is a local MCP plugin for developers whose AI coding agents fill their context windows with logs, file reads and search results. It stores large tool outputs on your machine so the agent can retrieve relevant passages as needed.

• Searchable tool output: Agents can search stored file analysis, web pages, API responses and browser snapshots instead of carrying complete outputs in the conversation.
• Coding agent integrations: It works with Claude Code, Cursor, Codex CLI, Gemini CLI, GitHub Copilot, OpenCode and Zed, though capabilities differ by integration.
• Tool routing controls: Supported hooks can enforce routing and block tool calls; integrations without hooks rely on instructions to the agent.
• Permission checks: The plugin applies configured command restrictions to sandboxed execution and rejects file execution paths that escape the project root.

The free plugin is source-available under Elastic License 2.0. It runs entirely on your machine without a network connection, account or telemetry. These facts apply to the plugin, rather than the model provider used by your coding agent.

A separate paid, hosted Platform offers Context Mode Insight for engineering teams. It identifies retry waste, error spikes, rework and blockers using opt-in forwarding of structural events such as tool names, file paths and error counts. Source code, prompt content and file content stay on developers' machines.
