Packages

CLI tool that connects to MCP servers via supported transports (command/stdio, streamable HTTP, and deprecated SSE), extracts server capabilities/tools/resources/prompts (optionally calling tools to include results), and outputs documentation in multiple formats (Markdown/JSON/HTML/PDF/Hugo) with customization via config files and templates.

Provides an MCP server (TypeScript) and a Revit add-in (C#) that bridge MCP tool calls from AI clients into Revit actions (read, create, modify, delete elements; also supports exporting/storing some project data).

A Spring Boot sample MCP server that exposes weather-related tools (forecast by lat/long and alerts by US state) via the Spring AI MCP Server WebMVC transport. It can run over HTTP SSE (default) or over STDIO for MCP clients.

Provides a Model Context Protocol (MCP) server that connects to a PostgreSQL database and exposes MCP tools/resources for listing tables, retrieving table schema/sample data, and executing SQL queries through a controlled interface.

pymcp-sse is an asynchronous Python library to build Model Context Protocol (MCP) servers and clients that communicate over HTTP/SSE. It provides base classes for server/client, tool registration and discovery, server push/notification support with keep-alives, and a multi-server client abstraction. It also includes an LLM client abstraction for integration with LLM providers (e.g., an Anthropic Claude example).

Studio (Deco CMS) is an open-source control plane for AI agents. It lets you hire/compose agents, connect and govern external tools via MCP (including “Virtual MCPs”), organize agents and tool connections into projects, and provides observability for tokens/costs/latency/errors. It can run locally with embedded PostgreSQL or via a cloud/team mode.

Provides a standards-compliant MCP Registry Server with a central registry catalog and an Admin API for managing sources/registries/entries. It supports multiple backend data sources (API/Git/File/Managed/Kubernetes) and optional PostgreSQL storage, with OAuth/OIDC-based enterprise auth support.

Provides an MCP server that exposes Umami Analytics data (websites, stats, pageviews, metrics, and active visitors) as MCP tools for MCP clients like Claude Desktop, VS Code/Copilot, Cursor, and others. Supports local stdio transport or an HTTP Streamable endpoint (/mcp) with session handling.

Unity editor tooling that exposes MCP “tools” to create and modify Unity AnimationClips and AnimatorControllers (e.g., create/get/modify .anim and .controller assets) via natural-language commands, built on top of the “AI Game Developer” Unity-MCP platform.

Provides a Python MCP server exposing tools to query a Qdrant vector database using text queries. It can auto-generate embeddings via an external Ollama server and supports advanced retrieval techniques such as query expansion (with RRF merging), HyDE, and LLM-based reranking.

B站（Bilibili）MCP Server that exposes ~27 tools for authentication, search/collection (videos, comments, subtitles, danmaku), content posting (dynamic, video upload, opus), analytics/rankings, and messaging/interaction via MCP clients (e.g., OpenClaw, Claude Code, Cursor, Cline).

Chessmata is a multiplayer chess platform with a browser 3D frontend, a WebSocket-based real-time game/matchmaking system, and programmatic access via both a REST API and an MCP server for AI agent tool-calling workflows. It includes a Python CLI with an MCP server and a UCI adapter to integrate existing UCI chess engines.

Provides an MCP (Model Context Protocol) server exposing tools/resources that query a hybrid GraphRAG datastore: Neo4j for graph-based context expansion and Qdrant for vector/semantic search, with hybrid retrieval combining both.

Provides an MCP server with tools for Indian government/finance-related lookups (e.g., IFSC, pincode, HSN/SAC, GST state codes), format/checksum validators (e.g., GSTIN, PAN, UPI VPA, Aadhaar checksum, etc.), and offline tax/fee calculators for FY2025-26. It supports offline-first operation with bundled datasets and an optional background/manual dataset refresh from a CDN.

Provides an MCP (Model Context Protocol) server for Obsidian that exposes semantic, graph-aware tools for an AI assistant to read, search, and modify content in an Obsidian vault over HTTP transport (optionally with HTTPS).

Provides an MCP (Model Context Protocol) server that exposes a single web-search tool backed by Perplexity AI’s API, intended for use with Claude Desktop (and similar MCP clients).

Provides an MCP server (with both STDIO and HTTP/container modes) that indexes and searches Prisma Cloud documentation and API references via MCP tools such as indexing, searching, and checking index/cache status.

Taskboard is a local, self-hosted project management app with a Kanban UI and CLI, backed by a single SQLite database. It includes a built-in MCP (Model Context Protocol) server exposing tools for projects, teams, tickets, board retrieval, and subtasks so AI assistants can manage work items directly on the local dataset.

UnityMCP provides an integration framework that connects an external AI client (via MCP) to a Unity Editor project. It includes a TypeScript MCP server/client component and a C# Unity Editor plugin that routes MCP tool/resource/prompt calls over TCP to Unity, where extensible command/resource handlers are auto-discovered and executed.

Communications API platform (formerly Nexmo) offering SMS, voice, video, and messaging APIs for building communication features into applications.
