OneMCP Hub

OneMCP Hub — an MCP server aggregator and management hub enabling AI agents to connect to and orchestrate multiple MCP servers through a single interface — managing MCP server registrations, routing tool calls to appropriate servers, providing a unified MCP endpoint for agent frameworks, and simplifying multi-MCP deployments.

Best When

An agent stack uses many MCP servers and needs centralized management — OneMCP Hub simplifies multi-server MCP architectures by providing aggregation and routing.

Avoid When

You only use one or two MCP servers — direct connection is simpler and more reliable than a hub.

Use Cases

• Aggregating multiple MCP servers under a single connection from complex agent stacks
• Managing and routing between specialized MCP servers from orchestration agents
• Simplifying MCP configuration for agents using many servers from infrastructure agents
• Providing a central registry of available MCP tools from discovery agents
• Load balancing or failover between redundant MCP servers from reliability agents
• Building MCP server marketplaces or catalogs from platform agents

Not For

• Simple single-server setups (unnecessary overhead for one MCP server)
• Teams without multiple MCP servers to manage
• Production use without careful security review (proxy adds attack surface)

Authentication

Methods: none

OAuth: No Scopes: No

No auth on hub itself — inherits auth from downstream MCP servers. Secure the hub's network access to prevent unauthorized tool invocation.

Known Gotchas

⚠ Hub adds a network hop — introduces additional latency for every tool call
⚠ Single point of failure — if hub goes down, all downstream MCPs become unreachable
⚠ Tool name collision resolution may be needed if multiple servers expose same-named tools
⚠ Authentication for downstream servers must still be configured per-server
⚠ Community project with limited documentation — setup may require trial and error
⚠ Error attribution difficult — errors from downstream servers may be hard to trace through hub
