description: Research a question using DuckDuckGo search and local AI analysis. Crafts search queries, fetches top results, and synthesizes a sourced answer — all locally. Use this instead of browsing the web yourself to save cloud context tokens.
compatibility: Requires Cercano server running and Python venv set up (run 'cercano setup').

# Cercano Research

Research a question using web search and local AI analysis. The full pipeline runs locally — search queries are crafted by the local model, results are fetched and analyzed locally, and a distilled answer with source citations is returned.

## MCP Tool

**Tool name:** `cercano_research`

## Parameters

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `query` | string | Yes | The research question to investigate. |
| `max_results` | int | No | Maximum pages to fetch and analyze (default 5). |
| `project_dir` | string | No | Project root directory for context-aware responses. |

## Pipeline

1. **Query crafting** — Local model generates 2-3 search queries from your question
2. **Parallel search** — DuckDuckGo searches run concurrently
3. **Deduplication** — Duplicate URLs removed, first occurrence preserved
4. **Parallel fetch** — Top N pages fetched and converted to plain text
5. **Synthesis** — Local model analyzes fetched content and produces a sourced answer

## Output

Returns a distilled answer with source URLs cited. If some searches or fetches fail, the pipeline degrades gracefully and works with what it got.

## Prerequisites

Requires the Python venv with the `ddgs` package. Run `cercano setup` to create it automatically.

## Examples

**Research a topic:**
```json
{
  "query": "How does the Ollama REST API work?"
}
```

**Research with more sources:**
```json
{
  "query": "Best practices for Go error handling",
  "max_results": 8
}
```

**Project-aware research:**
```json
{
  "query": "goquery CSS selector syntax for extracting article content",
  "project_dir": "/Users/me/my-project"
}
```
