-## Defaults
+## How It Runs

 - SearXNG binds to `127.0.0.1:8099` only.
- `context-web-search` defaults `search_web` to SearXNG, then falls back to
-  DuckDuckGo and Bing. Bing uses Chromium inside the web-search image.
- `fetch_url` uses upstream HTTP extraction. In `mcp-web-search` 1.3.0,
-  `engine=browser` is accepted but does not invoke Chromium yet.
- `context-docs` runs as a long-lived service on `127.0.0.1:8776` (Streamable
-  HTTP MCP) so every client shares one indexer and one Chroma writer. The
-  `bin/context-kit docs` stdio command is kept as a compatibility shim for
-  clients that cannot speak HTTP MCP.
+- `context-web-search` and `context-repomix` run as local stdio MCP commands.
+- `context-docs` runs as a local HTTP MCP service. `bin/context-kit docs` is a
+  stdio fallback for clients that cannot use HTTP MCP.
 - `context-docs` browser CORS is disabled by default; set exact local origins
  only when a browser-based client needs direct access.
 - Docs and model caches live in `$HOME/.local/share/context-kit`.
 - Docs refresh TTL defaults to `24h`.
- MCP containers are labeled `dev.context-kit=true` for safe inspection and cleanup.
- Repomix mounts only the current project read-only, not your whole home directory.
+- Repomix mounts only the current project read-only.
 - No code-editing MCP server is enabled by default.
