Nia – MCP server that gives more docs and repos to coding agents [Developer Tools]
48 points, 43 comments
Nia is an open MCP server that enhances coding agents by providing better access to external knowledge like docs and repos.
- Integrates with coding agents (Cursor, Continue, Cline) to improve accuracy by retrieving external knowledge
- Uses hybrid code search combining graph-based structural reasoning and vector-based understanding
- Parses repos/docs into ASTs across 50+ languages and chunks them by function/class boundaries
- Dynamically weights graph and vector search based on query intent for optimized results
- Multi-stage reranking includes semantic rerankers, cross-encoders, and LLM-based validators
- Improved Cursor's performance by 27% in internal evaluations
- Supports indexing multiple repos and docs for richer context in coding workflows
