What is mcp-hub-mcp CLAUDE.md?

A project guide for MCP Hub, a server that combines multiple Model Context Protocol servers behind one interface. MCP is a standard way for AI assistants to connect to external tools and data.

Use it when developing the TypeScript hub, running it locally, testing a linked package with npx, or preparing releases with its commit rules.

It documents the commands and architecture needed to build, run, link, and test the hub without scanning the whole codebase.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00850	$0.00850
Opus 5	$0.00425	$0.00425
Sonnet 5	$0.00170	$0.00170
Haiku 4.5	$0.00085	$0.00085

Security

Grade A, and why

mcp-hub-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview

This is an MCP (Model Context Protocol) Hub server that acts as a proxy/aggregator for multiple MCP servers. It bypasses tool limitations in AI assistants (especially Cursor's 40-tool limit) and provides a unified interface to multiple MCP servers.

Development Commands

Build and Run

# Install dependencies
pnpm install

# Build TypeScript to JavaScript
pnpm build

# Run the server (after building)
pnpm start

# Build and run in one command
pnpm dev

Development Workflow

# For testing changes locally with npx
npm link  # Creates a global link to the local package
npx mcp-hub-mcp  # Test the linked version

# To unlink after testing
npm unlink -g mcp-hub-mcp

Release Process

Uses semantic-release with Conventional Commits
Commits should follow: type(scope): description
Types: feat, fix, docs, style, refactor, perf, test, chore
Breaking changes: add ! after type or BREAKING CHANGE: in body
Releases are automated via GitHub Actions on the main branch

Architecture

Core Components

src/index.ts - Entry point that creates the MCP server with three tools:
- list-all-tools: Lists all available tools from connected servers
- call-tool: Executes a tool on a specific server
- find-tools: Grep-like search for tools matching regex patterns
src/server-manager.ts - McpServerManager class that:
- Loads server configurations from JSON file
- Manages connections to multiple MCP servers
- Proxies tool calls to appropriate servers
- Handles server lifecycle and error recovery
- Implements findTools method for regex-based tool search
src/types.ts - Type definitions and Zod schemas for:
- Server configuration validation
- MCP SDK type exports
- Configuration file structure
- Parameter schemas for all tools

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
