MCP Router — development, support and security updates ended 2026-09-18. Historical source and final release for existing users.
No outside reports on file
This unmaintained tool poses moderate risk because it coordinates connections to multiple servers without ongoing security updates, so any vulnerabilities discovered after 2026 won't be patched.
Based on public adoption and transparency signals as of Oct 21, 2026. Our opinion, not a code audit or security guarantee.

About MCP Router
MCP Router is a tool that connects Claude to multiple MCP servers (smaller tools that add capabilities). It routes requests from Claude to the right server based on what Claude needs. The project is no longer being updated as of September 2026.
Who it’s for
Developers who want to run several MCP servers at once without managing each connection separately. Users who need Claude to access different tools through a single connection.
Alternatives
- Claude's built-in MCP support: Use Claude directly with official MCP servers (actively maintained).
- Manual server management: Run individual MCP servers and connect them separately.
- Other MCP management tools: Look for actively maintained routing or orchestration tools in the MCP ecosystem.
Setup
Check these steps against the project’s own instructions before running anything.
Follow the project's README. Since this project ended development in 2026, check the GitHub repository for the final release version and installation steps for your system.

Risks to watch for
- Server access: This tool routes Claude to multiple external servers, so it can reach any data or functions those servers connect to.
- Routing misdirection: If an attacker controls a server or modifies routing rules, Claude might send requests to the wrong place.
- No active updates: Development ended in 2026, so new security issues won't be fixed.
- Credential exposure: If routing configuration stores API keys or tokens, they could leak if the config file isn't protected.
- Server confusion attacks: Malicious servers could pretend to be legitimate ones if routing doesn't verify identities carefully.
How to lower the risk
Least-privilege permissions
- Only connect servers that Claude actually needs.
- Give each server minimal access to your data and systems.
Network isolation
- Run this on a machine separate from critical systems if possible.
- Restrict which servers it can reach using network firewall rules.
Monitoring
- Log all routing decisions and server requests.
- Alert if unexpected servers are added to the router.
Red flags to watch for
- Requests being routed to servers you don't recognize.
- Configuration files changing without your approval.
- Errors or crashes that could indicate tampering.
