Provides persistent long-term memory for LLMs via local SQLite storage and semantic search, enabling recall across sessions without external APIs.

This tree-hugger-js MCP server by qckfx provides JavaScript and TypeScript code analysis capabilities through the tree-hugger-js AST parsing library, enabling AI assistants to parse, analyze, and transform code files or strings with intelligent pattern matching and refactoring operations. The implementation offers comprehensive code inspection tools including function/class/import extraction, scope analysis, and position-based node queries, combined with transformation capabilities like identifier renaming, unused import removal, and code insertion with proper formatting. Built for developers who need AI-powered code analysis and refactoring workflows, it supports both preview-only operations for safety and maintains transformation history, making it valuable for code review, legacy code modernization, and automated refactoring tasks across JavaScript/TypeScript codebases.

MCP server for serial port communication. Provides tools to open, read, write, and manage serial ports through the Model Context Protocol.

Enables interaction with GitHub API for repository management, commits, pushes, and pulls through natural language.

A local, self-custody MCP server that lets an AI agent trade the Cessio RFQ desk as both maker and taker, holding its own key and signing trades with operator-set limits.

Model Context Protocol server for discovering transforms, validating augmentation pipelines, rendering deterministic previews, and exporting reproducible pipeline specs.

Enables AI assistants to manage Omarchy desktop themes, including listing, switching, previewing, installing, removing, and rotating backgrounds.

Enables VoiceOS to read and write Discord messages through Composio's DISCORDBOT toolkit, with authentication handled via Composio Connect.

An MCP server that enables AI assistants like Claude to interact with FL Studio's piano roll, allowing users to create melodies, chord progressions, and musical patterns through natural language with automatic, real-time updates.

MCP server for playing chess matches between AI agents across computers, enabling match creation, move submission, and turn waiting.

Implements Chain of Thought methodology for extended sequential thinking on complex reasoning tasks. Enables AI clients to break down and solve problems that require deep, step-by-step logical analysis.

This LibSQL-based persistent memory tool for MCP, developed by Scott Spence, provides a database interface for AI models to store and retrieve information. Built with TypeScript and leveraging the LibSQL client, it offers functionality for managing entities and relations in a knowledge graph structure. The implementation focuses on providing a robust, SQL-based storage solution that can be used locally or with remote databases. It's particularly useful for maintaining context across conversations, building knowledge bases, or creating persistent memory systems for AI assistants, enabling long-term information retention without requiring complex database management.

Index source code into a local knowledge base, search with keyword + semantic + hybrid modes.

An interface for interacting with Google Firestore databases directly through Claude Desktop, supporting operations like creating, reading, updating, and querying documents across collections.

Provides full CRUD access to the AbraFlexi (formerly FlexiBee) accounting platform through MCP-compatible tools. Supports invoice management, contact and product administration, bank transaction handling, and generic evidence queries. Features read-only mode for safe monitoring and multiple transport options.

A MCP server for google docs, Full tutorial on how to connect it with claude!

Enables searching and querying City of Harrisburg GIS open geospatial data (parcels, zoning, public works) via ArcGIS feature services using natural language.

nocodb mcp server

A native Windows desktop application built with C++ Builder VCL that hosts multiple protocol servers simultaneously, each running on a dedicated HTTP port. Includes three built-in modules: Database (supporting MS SQL Server, PostgreSQL, and Firebird with schema exploration, query execution, and execution plan analysis), Project Memory (an SQLite-backed knowledge base with full-text search including Cyrillic morphology support), and SQL Query Helper (query management and C++ code generation from database metadata). Distributed as standalone Windows binaries with no external dependencies.
