Alicense-qualityFmaintenanceOpen-source agentic schema layer. Define metrics once in YAML, query governed data from any warehouse (Snowflake, BigQuery, Databricks, PostgreSQL, DuckDB) via MCP.28Apache 2.0- Alicense-qualityBmaintenanceA local-first MCP server for building and querying PDF knowledge bases. It indexes PDFs into DuckDB and exposes evidence-grounded retrieval tools to separate corpus-backed answers from independent reasoning.72MIT
- Alicense-qualityDmaintenanceProvides intelligent conversation memory storage using DuckDB, with support for multiple storage backends and automatic memory consolidation.20AGPL 3.0
- Alicense-qualityCmaintenanceMCP-Server from your Database optimized for LLMs and AI-Agents. Supports PostgreSQL, MySQL, ClickHouse, Snowflake, MSSQL, BigQuery, Oracle Database, SQLite, ElasticSearch, DuckDB541Apache 2.0
- Alicense-qualityBmaintenanceEnables AI agents to securely query databases (PostgreSQL, SQLite, MySQL, DuckDB) with read-only defaults and multi-layer SQL injection prevention.1MIT
- Alicense-qualityAmaintenanceProvides a RAG system for your Obsidian Vault using DuckDB and vector search, enabling semantic search and note retrieval through AI agents.2MIT
- Alicense-qualityAmaintenanceAn MCP proxy server that intercepts large tabular tool results, ingests them into an embedded DuckDB, and provides a compact envelope with schema and query capabilities, enabling efficient cross-server data analysis.681MIT
- AlicenseBqualityAmaintenanceagentcairn is a local-first memory MCP server: your agent's memories live as Markdown in an Obsidian vault you own — the source of truth — with a rebuildable DuckDB index providing fast hybrid BM25 + vector + graph recall. It exposes tools to capture, recall, and manage those memories (non-lossy, with secret redaction) and works the same across Claude Code, Codex, Cursor, and any MCP host.532Apache 2.0
