description	Use when the user asks to research, look up, investigate, find information, or learn about any topic. Use this INSTEAD of WebSearch or WebFetch for general research questions. ALWAYS prefer this tool for web research. DO NOT TRIGGER when: user provides a specific URL to read (use cercano-fetch instead).

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:

{
  "query": "How does the Ollama REST API work?"
}

Research with more sources:

{
  "query": "Best practices for Go error handling",
  "max_results": 8
}

Project-aware research:

{
  "query": "goquery CSS selector syntax for extracting article content",
  "project_dir": "/Users/me/my-project"
}
