Cognee is an open - source project that provides memory functions for AI agents. It builds a dynamic knowledge graph through a modular ECL pipeline, supports multiple data sources and formats, reduces hallucinations, and lowers costs.

Hivemind is an Obsidian plugin that provides AI firewall capabilities for fictional world - building, research, and knowledge management. It ensures that AI tools collaborate based on the real information in the user's notes through timeline views, relationship graphs, and canonical workflows, preventing AI hallucinations.

Chainguard is an MCP server that provides task tracking, syntax validation, long-term memory, and intelligent context management for Claude Code, including code semantic search, hallucination prevention, and a kanban system.

An MCP service that prevents AI hallucinations. When AI is uncertain, it can ask humans for help instead of being over - confident, improving development efficiency through a simple Q&A mechanism.

This is a Quran search engine server based on the MCP protocol, aiming to provide accurate and hallucination-free Quranic verse query services for AI assistants. It uses a dedicated search engine to handle Arabic normalization, root, and lemma matching, ensuring the absolute accuracy of the returned verse texts, while the AI is only responsible for understanding the user's natural language query intentions.

A development documentation server based on the MCP protocol, providing functions such as document crawling, local loading, precise search, and detail retrieval, to solve the document hallucination problem in AI development.

MCP-NixOS is a model context protocol server that prevents AI assistants from having hallucinations about the NixOS system, providing real-time access to NixOS packages, system options, Home Manager settings, and nix-darwin configurations.

A development document server based on the MCP protocol, providing accurate framework document retrieval services and solving the API hallucination problem in AI development.

DevDocs-MCP is a localized MCP server that provides fixed-version and authoritative documentation data for AI assistants, eliminating AI hallucinations and ensuring the accuracy of API context.

Libragen is a local RAG library construction tool used to connect AI assistants (such as Claude) with your actual documents and code libraries. It reduces AI hallucinations by creating a searchable knowledge base, supports building from local files or Git repositories, and is directly integrated into the AI workflow through the MCP protocol.

An MCP server based on two - stage SQL generation, which converts natural language to SQL, reduces the hallucination risk and enhances the trust of non - technical users.

FOCUS DATA MCP Server is an AI assistant service that converts natural language into SQL statements. It uses a two-step generation scheme to control LLM hallucinations and increase the trust of non-technical users in SQL results.

AI Coding Assistant Security Scanner, scans code vulnerabilities, detects AI hallucination packages, and prevents prompt injection attacks through MCP or CLI, supports 12 languages and more than 1,700 security rules

RagAlgo is an MCP server that provides mathematically scored financial context (South Korean stocks/cryptocurrencies) for AI agents. It focuses on using daily closing data to build a 'factual state' to prevent AI hallucinations caused by real - time market noise, aiming to build investment advisors rather than high - frequency trading robots.

A Java class analysis service based on the MCP protocol. It provides accurate code analysis capabilities for LLMs by decompiling dependent JAR packages and solves the dependency hallucination problem in AI coding.

GitMCP is a free and open - source remote MCP server that can transform any GitHub project into a documentation center, enabling AI tools to access the latest documentation and code and reducing hallucinations.
