Add PieKBS to Open-source Projects

[jasen215]

Hi, thanks for maintaining this list - it's a great resource.

I'd like to add PieKBS to the Open-source Projects section.

• Repo: https://github.com/pieteams/piekbs
• License: MIT
• Docs: https://pieteams.github.io/piekbs/

PieKBS is a local-first knowledge search engine for agents. It distills raw documents into a structured Markdown wiki and exposes MCP tools for search and deep-reading. Key features:

• FTS5 full-text search with BM25 scoring (no embedding required)
• Graph-based document expansion via citation/support/wiki/related_to links
• Multi-hop tag expansion for discovering related documents through shared keywords
• MCP protocol support for seamless integration with AI agents
• Pure Go binary with no external dependencies

The graph functionality supports document relationships (cites, supports, contradicts, supersedes) and enables agents to navigate knowledge networks during retrieval.

Happy to adjust the wording or placement if needed.
