Stop Juggling Multiple MCP Servers

If you're running more than a few MCP servers, you know the drill: cluttered client configs, namespace conflicts, and the constant dance of enabling/disabling servers depending on your current project. The plugged.in MCP Proxy eliminates this complexity by giving you a single entry point to all your MCP tools.

The Multi-Server Problem

Most developers start with one MCP server, then two, then suddenly you're managing configurations for filesystem access, database connections, API integrations, and development tools across multiple clients. Your Claude Desktop config becomes a mess of server definitions, each with their own authentication, and switching between different toolsets means constant reconfiguration.

Before:

{
  "mcpServers": {
    "filesystem": { "command": "...", "env": {...} },
    "database": { "command": "...", "env": {...} },
    "github": { "command": "...", "env": {...} },
    "aws": { "command": "...", "env": {...} },
    "slack": { "command": "...", "env": {...} }
    // ... and 10 more servers
  }
}

After:

{
  "mcpServers": {
    "pluggedin": {
      "command": "npx",
      "args": ["-y", "@pluggedin/mcp-proxy@latest"],
      "env": { "PLUGGEDIN_API_KEY": "your-key" }
    }
  }
}

Smart Aggregation with Namespace Isolation

The proxy doesn't just forward requests—it intelligently manages your MCP ecosystem. Each server gets proper namespace prefixing, so github_create_issue and database_create_table coexist without conflicts. You get clean, organized tool lists that make sense.

Want to switch from your "development" toolset to your "production monitoring" workspace? One click in the plugged.in app, and your entire MCP environment changes without touching client configurations.

Production-Ready Security

Unlike simple proxy solutions, this includes enterprise-grade security:

• SSRF Protection: Blocks access to internal networks and sensitive services
• Command Allowlisting: Only approved commands (node, python, etc.) can be executed
• Header Sanitization: Prevents injection attacks and validates all headers
• Rate Limiting: 60 tool calls per minute, 100 API calls per minute
• Authentication Flexibility: Optional Bearer token auth for HTTP mode

Multiple Transport Options

Run it how you need it:

STDIO Mode (default) - Perfect for direct client integration:

npx -y @pluggedin/mcp-proxy@latest --pluggedin-api-key YOUR_KEY

HTTP Server Mode - Great for team environments or web integration:

npx -y @pluggedin/mcp-proxy@latest --transport streamable-http --port 8080

Docker - Production deployments with minimal footprint:

docker run -d -p 12006:12006 \
  -e PLUGGEDIN_API_KEY="your-key" \
  pluggedin-mcp-proxy:latest --transport streamable-http

Real-World Workflow Integration

Here's where it gets practical. Instead of managing individual server lifecycles, you configure once and let the proxy handle discovery, health checks, and request routing. Your existing MCP clients (Claude, Cline, Cursor) see one stable interface while your actual server infrastructure can change underneath.

Need to add a new API integration? Add it to your plugged.in workspace—no client reconfiguration needed. Want to test a new tool without breaking your existing setup? Create a new workspace and switch seamlessly.

The Web Management Interface

The companion plugged.in app gives you visual control over your entire MCP ecosystem. See which tools are available, test them interactively, manage authentication credentials, and organize different workspace configurations. It's like having a control panel for your AI toolchain.

Getting Started in 30 Seconds

1. Get an API key from plugged.in/api-keys
2. Run: npx -y @pluggedin/mcp-proxy@latest --pluggedin-api-key YOUR_KEY
3. Add the proxy to your MCP client config
4. Access all your MCP servers through one interface

The proxy discovers your configured servers automatically and presents them as a unified toolset. No more switching between different server configurations or managing individual connection states.

Quick test: Run the proxy and call pluggedin_discover_tools to see it automatically find and configure your available MCP servers. It's the kind of "just works" experience that makes you wonder why you were managing everything manually before.

If you're running multiple MCP servers and tired of configuration overhead, this proxy eliminates the complexity while adding the management features you actually need.
