MCP servers

A template repository for creating custom Model Context Protocol tools for the Unity game engine, letting a developer build and package their own Unity MCP tools as a distributable Unity package in about 30 minutes.

• MCP servers

An MCP server, specialized for academic citation analysis, that lets an AI assistant build citation networks from DOIs, calculate author impact metrics such as the h-index, and run graph algorithms like PageRank directly inside a conversation.

• MCP servers

A semantic search engine for the OHDSI medical vocabulary, built as a Rust API and autocomplete service with a React frontend, also reachable as an MCP server for AI agents.

• MCP servers
• RAG

A local, read-only MCP gateway that aggregates SQLite, MySQL, and PostgreSQL connections behind one endpoint, applying SQL-syntax-tree validation, row and time limits, and a full audit log so an AI agent's database access stays controlled.

• MCP servers
• Databases

An MCP server that fuses keyword search, vector embeddings, directory-level summaries, and knowledge-graph expansion into one retrieval tool, giving Claude Code, Copilot, and Cursor a structural understanding of a codebase beyond plain grep.

• MCP servers
• Agent memory

A tool that turns a local folder into a public Model Context Protocol endpoint over a tunnel, exposing five deliberately minimal tools for running shell commands and transferring files, as a VS Code extension or standalone desktop app.

• MCP servers
• Networking

A local-first retrieval-augmented research assistant that helps scientists and students search, understand, and organize academic literature across sources such as Semantic Scholar, PubMed, and arXiv, exposed through an MCP server and REST API.

• MCP servers
• RAG

An open-source gateway that enforces Model Context Protocol tool-call policy inside a hardware trusted execution environment, so a governed agent process cannot alter or bypass its own policy engine.

• MCP servers
• Security

A Rust-based desktop AI assistant and proxy that runs a tool-driven plan, execute, and review workflow across multiple language models, with a centralized MCP hub, sub-agent delegation, and persistent memory and skills.

• Agent frameworks
• MCP servers

A single gateway that unifies REST, A2A, and Google ADK agents behind one API and one MCP endpoint, converting every response into a uniform stream of AG-UI events with role-based access control.

• Agent frameworks
• MCP servers

A FastAPI and MCP server that turns the source data of the 2009scape game into a queryable SQLite dataset for a wiki front end or an AI agent.

• MCP servers
• APIs

A self-hosted platform for MCP Apps and agent automations that turns an installed MCP connector into an interactive sidebar UI with live agent data sync, runnable on demand or on a cron schedule.

• Agent frameworks
• MCP servers

A catalogue of developer infrastructure free tiers, startup credits and pricing across more than 1,500 vendors, exposed as a website, a JSON API and an MCP server so a coding agent can compare deals while choosing a stack.

• MCP servers
• Curated lists

A semantic search engine over arXiv, the Stacks Project and other sources that finds mathematical theorems and the papers containing them, offered as a REST API and as an MCP tool for AI agents.

• MCP servers
• RAG

The official Pinecone extension for Gemini CLI, adding Agent Skills and MCP tools for managing vector indexes, running semantic search and building document question-answering assistants from the terminal.

• MCP servers
• Databases

A local, on-device MCP server for macOS that captures everything you have seen, read, typed and heard across your desktop through on-screen OCR, so any connected agent can recall your recent activity.

• MCP servers
• Agent memory

An MCP server that has a second model such as OpenAI Codex or Google Gemini review code that Claude Code just wrote, returning structured feedback inline using a subscription you already hold.

• MCP servers
• Code quality

A testing tool for MCP servers that connects over real stdio, SSE or HTTP transport, checks tool responses against YAML-defined assertions, and lints and fuzzes servers for schema and protocol issues.

• MCP servers
• Testing

A Codex plugin that runs an LSP client in the background so Codex gets post-edit diagnostics automatically, plus explicit MCP tools for language-aware operations such as go-to-definition and rename.

• Coding agents
• MCP servers

A drop-in MCP server that gives Claude Code, Cursor, Windsurf and other MCP clients persistent cognitive memory, backed by a Rust engine with temporal decay, contradiction detection and a knowledge graph.

• MCP servers
• Agent memory

The official distribution repository for Supabase's skills and MCP adapters for AI coding assistants, bundling general Supabase and Postgres-performance guidance for Claude Code, Cursor, Codex and others.

• MCP servers
• Agent skills

A local-first memory layer for AI assistants that runs an MCP server over a local SQLite file, so tools such as Claude Code, Cursor and GitHub Copilot can share durable memory about a user, their work and past decisions.

• MCP servers
• Agent memory

A self-contained MCP server for undetectable Chrome browser automation, sharing one backend across many concurrent AI agent sessions with named, persistent browser profiles.

• MCP servers
• Browser automation

A multi-interface music analysis and generation toolkit built on the music21 library, offering the same 13 analysis tools through an MCP server, an HTTP API, CLI tools and a Python library.
