A hub server that connects to and manages other MCP (Model Context Protocol) servers.
Overview
This project builds an MCP hub server that connects to and manages multiple MCP (Model Context Protocol) servers through a single interface. It helps prevent excessive context usage and pollution from infrequently used MCPs (e.g., Atlassian MCP, Playwright MCP) by allowing you to connect them only when needed. This reduces AI mistakes and improves performance by keeping the active tool set focused and manageable.
Key Features
- Automatic connection to other MCP servers via configuration file
- List available tools on connected servers
- Call tools on connected servers and return results
Configuration

]
}
}

Built from this server's own package name, version and transport as found in its source — not copied from anyone's documentation, so it cannot drift against a page we do not control.

Questions
What tools does Hub expose?
7 in total: 7 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is Hub safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.
What credentials does Hub need?
No credential environment variables were found in its source, so it appears to need none.
How does Hub run?
It speaks stdio and streamable-http, so it runs as a local process your client starts. It is published on npm as mcp-hub-mcp at 1.3.1.
How current is this page?
The grade is for one exact copy of the source (0519fbd5346c), read on 2026-10-07. The repository is watched and re-audited when it changes.
