Search and page fetching use the Node.js runtime built into pi. ## Tools ### `web_search` Search the web using DuckDuckGo. Returns titles, URLs, and content snippets. **When to use:** - The user asks to find information online - Looking up documentation not available locally - Verifying facts or looking up recent data **Parameters:** - `query` (string, required): Search query - `maxResults` (number, optional, default 5, max 10): How many results to return - `maxResponseChars` (number, optional): Truncate output to this many characters **Guidelines:** - Always follow up with `web_read` if the user needs full page content - DuckDuckGo is used — no API key required - Rate limits apply; avoid rapid repeated queries ### `web_read` Fetch a web page and extract readable content. **When to use:** - You need the full content of a specific page - Following up on a `web_search` result - Reading documentation or articles **Parameters:** - `url` (string, required): Page URL (must be `http:` or `https:`) - `maxChars` (number, optional, default 8000, max 50000): How many characters of content to return - `maxResponseChars` (number, optional): Truncate output to this many characters **Guidelines:** - Works best on article/blog pages - JavaScript-heavy SPAs may return limited content (no JS execution) - Private/internal URLs (`localhost`, `127.0.0.1`, `169.254.x.x`, etc.) are blocked for security ## Limitations - **No JavaScript rendering:** Pages that require JS to load content will return incomplete results. - **HTML only:** PDFs or other binary formats are not supported. - **DuckDuckGo rate limiting:** Aggressive querying may be throttled. --- > Source: [emanuelcasco/pi-mono-extensions](https://github.com/emanuelcasco/pi-mono-extensions) — distributed by [TomeVault](https://tomevault.io).
