Pyrite is a knowledge infrastructure platform. You store structured knowledge in markdown files with YAML frontmatter, validated against schemas, versioned in git, and searchable by any AI through MCP.
The problem Pyrite solves
Your AI agents have no memory. Your knowledge is trapped in platform silos. Every new chat starts from zero. Pyrite gives you structured, validated, git-versioned knowledge bases that any AI can read and write through a built-in MCP server.
How it works
1. Markdown files are the source of truth — plain text with YAML frontmatter, readable in any editor 2. A search index (SQLite FTS5 + optional vector embeddings) sits on top for fast search 3. Multiple interfaces access the same data: CLI, REST API, MCP server, and this web UI 4. Plugins add domain-specific entry types, tools, and workflows
