}Context Mode is an MCP server and multi-platform context-management system for AI coding agents. It is designed to keep raw tool output out of the model context window, index useful session events locally, and retrieve only the context that matters for the current task.
For Claude Code, the project documents a plugin marketplace install with hooks, slash commands, and routing enforcement. It also provides an MCP-only install for trying the server without automatic hooks.
These sources were reviewed on 2026-06-05. Prefer the live repository and site for current platform support, plugin instructions, hook behavior, command names, and license details.
For MCP-only Claude Code setup:
claude mcp add context-mode -- npx -y context-mode
For JSON-based MCP clients:
{
"mcpServers": {
"context-mode": {
"command": "npx",
"args": ["-y", "context-mode"]
}
}
}
For Claude Code plugin setup with hooks and slash commands, use the project README's marketplace instructions and run its doctor command after installation.
Context Mode changes how agents route tool calls and store context. Review the installed MCP server, hooks, and local data stores before using it with sensitive projects. Purge indexed state when changing clients or projects, and inspect original files or outputs when exact evidence matters.
Existing context and statusline entries cover related workflow ideas, but no
mksglu/context-mode MCP entry or source URL was found in content/mcp.

| Safety notes | ✓Context Mode encourages agents to execute scripts and route large outputs through sandbox tools; review allowed commands and workspace boundaries. Hook-based installs can affect tool routing automatically. Verify the installed hooks and settings before using it in shared or sensitive workspaces. Indexed session state can influence future retrieval and continuity; purge state when switching projects, clients, or sensitivity levels. Do not rely on compressed or searched summaries for high-stakes decisions without inspecting original files or outputs. | ✓Code Index MCP reads repository files, builds shallow and deep indexes, exposes file summaries, and can return source snippets through search and file resources. Point `--project-path` at one approved repository; avoid broad parent directories, home directories, generated dependency trees, or secret-heavy paths. Deep indexing and watcher refreshes can consume CPU, memory, disk IO, and temp storage on large codebases. The server can create and clear index/cache settings and temporary directories used for stored index data. Search results, file summaries, and symbol bodies can surface credentials, private code, customer data, internal URLs, or proprietary implementation details if they exist in the repository. | ✓Tools create and delete indexes and documents and rotate API keys — scope the key and confirm destructive actions. Settings and index deletes change live search behavior; review before running them through Claude. | ✓get_rewrite may replace marketing copy; review output before publishing to production sites. get_score fetches and analyses live page content from URLs you provide. OAuth tokens grant persistent BittleBits access until revoked. Automated rewrites can introduce factual errors; human review is recommended. |
| Privacy notes | ✓Context Mode can index file edits, git operations, tasks, errors, user decisions, local files, and command output in SQLite/FTS5 stores. Indexed data may include source code, logs, secrets accidentally printed to terminal, customer data, repository paths, and private prompts. Local analytics and statusline data can reveal workflow patterns, tool usage, and project activity. | ✓Tool calls may expose file paths, filenames, source code snippets, imports, classes, methods, functions, symbols, search matches, complexity summaries, and project settings. Index data and temp directories can persist derived repository structure or symbol metadata outside the source tree. File watcher status, exclude patterns, and settings can reveal local project layout and development conventions. If an MCP client forwards tool results to a model provider, repository contents and search snippets may leave the local machine. Exclude secrets, generated artifacts, vendored dependencies, build output, and private data before indexing. | ✓Indexed documents and search results enter the MCP client context and the model's prompt. MEILI_HTTP_ADDR and MEILI_MASTER_KEY are secrets — keep them in the client config or environment. | ✓Page URLs and content sent to get_score are processed by BittleBits for analysis. Rewrite requests may include proprietary marketing text; avoid sending unreleased campaign copy to untrusted sessions. OAuth sessions should not be shared across users or pasted into public support threads. |
