mcp-registry-mcp

MCP server for managing MCP server registries — health checks, duplicate detection, and configuration portability.

52% of remote MCP servers are dead. Only 9% are fully healthy. This server gives you a central registry to track what you have, what works, and what overlaps — before MCP sprawl becomes the microservices sprawl of 2018.

Install

npx mcp-registry-mcp

Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "mcp-registry": {
      "command": "npx",
      "args": ["mcp-registry-mcp"]
    }
  }
}

From source

git clone https://github.com/mdfifty50-boop/mcp-registry-mcp.git
cd mcp-registry-mcp
npm install
node src/index.js

Tools

register_server

Register an MCP server with metadata.

health_check

Check server health. Probes HTTP endpoints, measures latency, tracks uptime over time.

Returns: health status, latency, uptime percentage, last 5 check results.

find_duplicates

Find servers with overlapping tool definitions using Jaccard similarity on tool name sets.

Returns pairs of overlapping servers with similarity scores and verdicts: likely_duplicate (>80%), significant_overlap (>50%), or minor_overlap (>30%).

export_config

Export portable MCP configuration for different clients.

Returns a ready-to-paste JSON config block with client-specific instructions.

get_inventory

List all registered servers with health and usage stats.

Returns: server list with health status, uptime percentage, tool count, and summary stats.

recommend_consolidation

Suggest merging duplicate or overlapping servers to reduce sprawl.

Returns: recommendations to keep/retire specific servers with similarity scores and reasoning.

check_before_install

Pre-install health, security, and duplicate check for a server you are considering adding.

Returns: reachability, latency, TLS status, CORS headers, duplicate risk, and install recommendation (OK / CAUTION / DO NOT INSTALL).

Resources

Usage Pattern

1. register_server — add each MCP server you use
2. health_check — verify each server is alive
3. find_duplicates — spot overlapping tools
4. recommend_consolidation — get merge suggestions
5. export_config — generate config for your client
6. check_before_install — vet new servers before adding

Tests

npm test
