What it does
mcphub is a self-hosted gateway and control plane that lets you connect, manage, and operate multiple MCP servers from a single interface. It acts as a central hub for routing requests to different MCP servers and provides administrative controls over their lifecycle and permissions.
Who it’s for
DevOps engineers, platform teams, and builders who need to manage multiple MCP server instances at scale or want centralized control over MCP infrastructure. Organizations seeking to self-host rather than rely on third-party MCP routing services.
Copy-paste setup
Check these steps against the project’s own instructions before running anything.
Verify against the repo README at https://github.com/samanhappy/mcphub (opens external site) for current installation instructions. The project appears to be a self-hosted Go/Node service; typical setup likely involves cloning the repository, installing dependencies, and configuring server endpoints and authentication. Exact steps and package managers (Docker, npm, or standalone binary) should be confirmed in the official documentation.
Risks
- Central point of failure: all MCP server access flows through mcphub, creating a single target for compromise or misconfiguration that could expose multiple downstream services
- Credential management: the gateway must store and manage credentials/tokens for each connected MCP server, increasing attack surface if not properly secured with encryption and access controls
- Prompt injection at the gateway layer: malicious requests routed through mcphub could attempt to manipulate server responses or inject payloads affecting all connected clients
- Data exfiltration: centralized logging and request routing may expose sensitive prompts, API keys, or user data if logs are not properly secured and rotated
- Supply chain risk: as a self-hosted tool, it depends on the maintainer's security practices and update velocity; users are responsible for patching and auditing the codebase
How to stay secure
mcphub Security Hardening Guide
Least-privilege permissions
- Restrict admin access: Only assign gateway administrator rights to essential staff; regular users should have access only to the specific AI servers they need for their job
- Credential segregation: Store login credentials and API keys for each connected server separately, and use tools that encrypt them at rest (when not in use)
- Role-based access control: Configure different permission levels—some users can only read data, others can execute actions—to limit damage if an account is compromised
- Rotate credentials regularly: Change passwords and API keys every 90 days and immediately after staff departures
Network isolation
- Restrict gateway access: Only allow trusted internal networks (your company devices) to connect to mcphub; block public internet access entirely
- Separate network segment: Place mcphub on its own protected network area, isolated from general employee computers and public-facing systems
- Firewall rules: Set up strict rules allowing mcphub to communicate only with approved AI servers and databases it needs; block all other outbound connections
- VPN requirement: Require employees to use a VPN to access the gateway, encrypting all traffic in transit
Monitoring
- Enable detailed logging: Turn on all available activity logs (who accessed what, when, and what they did) and store them in a separate, tamper-proof system
- Review access patterns: Regularly check logs for unusual activity, such as large data downloads or access attempts from unfamiliar locations
- Set up alerts: Configure automatic notifications when suspicious events occur, like multiple failed login attempts or access to restricted servers
- Audit trails: Maintain timestamped records of all configuration changes made to mcphub for compliance and incident investigation
Red flags to watch for
- Update lag: If mcphub hasn't released security patches within 2-4 weeks of a public vulnerability announcement, consider whether the tool remains trustworthy
- Unexplained data volumes: Large amounts of data flowing through mcphub or unusual requests routed to multiple servers simultaneously may indicate a breach
- Slow performance degradation: A sudden slowdown could signal unauthorized processes running on the gateway or a denial-of-service attack in progress
- Credential leaks: If any passwords, API keys, or authentication tokens appear in logs, error messages, or backups, treat it as a security incident and rotate credentials immediately
Alternatives
- Anthropic Claude Desktop built-in MCP client—native integration without additional gateway overhead, though less multi-tenancy support
- Zed MCP connector—editor-native MCP support for developers, lighter-weight but not a centralized control plane
- LangChain or LlamaIndex agent frameworks—higher-level orchestration layers that can route to multiple tools and models without dedicated MCP gateway
- Manual direct MCP server connections—no gateway, lower latency and fewer single points of failure, but requires managing connections per client
