"A knowledge base for storing and accessing information" matching MCP servers:

A cross-project knowledge base MCP server supporting three-layer search (text matching, TF-IDF, and semantic vectors) with a Web UI for management.

基于MCP协议的知识库服务器，内置LLM层，提供结构化知识存储、语义搜索和主动知识推送，支持通过工具进行知识学习、搜索和关联推理。

A local knowledge base server that connects to AI assistants, turning markdown files into a semantically searchable memory layer via OpenAI embeddings and SQLite.

A local document processing server that can index various document formats (PDF, DOCX, TXT, HTML) and answer questions based on their content using the Model Context Protocol.

Provides tools for listing and retrieving content from different knowledge bases using semantic search capabilities.

Provides onchain tools for Claude AI to interact with the Base blockchain and Coinbase API, enabling wallet management, fund transfers, and smart contract deployment.

Enables extracting explicitly stated contract metadata, clauses, and obligations from user-supplied contract text without storing or modifying the data.

Enables access to a notes knowledge base via MCP, providing tools for keyword search, note creation, and retrieval, along with browseable note resources.

An MCP server that guides AI assistants to navigate documentation using their built-in tools (grep, file reading) instead of traditional RAG.

Enables cross-session memory and recall for AI coding assistants through a git-synced knowledge base, hybrid semantic and TF-IDF search across tool transcripts, and automatic distillation of insights with secrets scrubbing.

MCP server enabling Claude Code to capture screenshots of Windows applications through WSL2, allowing AI to diagnose UI errors and verify layouts.

Enables MCP clients to connect to a privacy-first, self-hostable workout planning and training log, allowing coaching agents to preview and apply program changes while accessing training data through OAuth-protected endpoints.

A persistent knowledge base server for MCP development with GitHub integration and removal blocklist.

An MCP server that enables semantic search over a private knowledge base via pgvector, with GitHub OAuth authentication and a RAG pipeline.

An MCP server that provides onchain tools for Claude AI to interact with the Base blockchain and Coinbase API, enabling wallet operations, testnet ETH, balance checks, fund transfers, and smart contract deployment.

MCP server to fetch DeFi yield opportunities on Base chain, including Aerodrome LP and Moonwell lending, with pay-per-call via x402 micropayments.

Enables AI agents to search, read, create, and maintain a local-first knowledge base using hybrid retrieval and Markdown note management through the Model Context Protocol.

Explains any Base mainnet transaction hash by returning a structured JSON with action type, assets moved, risk flags, and cost details, using deterministic on-chain decoding without LLM.

A Model Context Protocol server that provides LLMs with read and write access to Feishu Base (飞书多维表格) databases, enabling them to inspect schemas and manipulate records through natural language.

A Model Context Protocol (MCP) server that provides persistent memory and context management for AI systems through a structured 5-phase optimization workflow.
