MCPJungle Details
MCPJungle is a self-hosted MCP Gateway and Registry for AI agents. It serves as a central registry and gateway to manage Model Context Protocol (MCP) servers and the tools they expose. By consolidating MCP server registration, tool discovery, and access control, MCPJungle enables AI agents and clients to discover, group, and securely invoke tools from a single, unified gateway. The project provides a CLI, Docker-based deployment options, and enterprise-ready features such as tool grouping, access control, and observability to streamline MCP-based workflows across organizations.
Use Case
MCPJungle acts as a centralized registry and gateway for MCP servers and their tools. It supports both Streamable HTTP and STDIO transports, enabling you to register remote MCP servers and invoke their tools through a single endpoint. It also lets you create Tool Groups to expose a curated subset of tools to specific clients, manage enabling/disabling of tools and prompts, and integrate with clients like Claude or Cursor. Example use cases include registering a calculator MCP server (streamable_http) and a filesystem MCP server (stdio), listing and invoking tools, and creating Claude-specific tool groups.
Example usage from the docs:
mcpjungle register --name calculator --description "Provides some basic math tools" --url http://127.0.0.1:8000/mcpmcpjungle list tools<h1 class="text-2xl font-semibold mt-5 mb-3">Check tool usage</h1>
mcpjungle usage calculator__multiply
<h1 class="text-2xl font-semibold mt-5 mb-3">Call a tool</h1>
mcpjungle invoke calculator__multiply --input '{"a": 100, "b": 50}'

Notes and warnings from the docs:
MCPJungle is distributed as a stand-alone binary. Install it via Homebrew or download from the Releases page. Docker-based deployments are supported via docker-compose. For persistence, a Postgres DSN can be supplied; otherwise a SQLite database file mcpjungle.db is created by default. No Node.js prerequisite is required for MCPJungle itself.
