Mcp Registry

Summary

Tracks and manages your growing collection of MCP servers before it turns into chaos. Register servers with metadata, run health checks that probe HTTP endpoints and measure latency, and use Jaccard similarity on tool names to find duplicates across your setup. It surfaces consolidation recommendations when you have overlapping functionality, exports portable configs for Claude Desktop, Cursor, or VSCode, and runs pre-install checks on new servers to flag dead endpoints or duplicate tools before you add them. Useful once you're juggling more than a handful of MCP servers and need visibility into what's alive, what overlaps, and what can be retired.

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.

ParamTypeDefaultDescription
namestringrequiredServer name (e.g. "filesystem-mcp")

transportstring"stdio""stdio", "sse", or "streamable-http"
descriptionstring""What this server does
org_idstring"default"Organization for multi-tenant grouping
toolsstring[][]Tool names this server provides

health_check

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

ParamTypeDescription
server_idstringServer ID from register_server

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.

ParamTypeDefaultDescription
org_idstring"default"Organization to scan

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.

ParamTypeDefaultDescription
server_idsstring[]requiredServer IDs to include
target_clientstring"claude_desktop""claude_desktop", "cursor", "vscode", or "generic"

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

get_inventory

List all registered servers with health and usage stats.

ParamTypeDefaultDescription
org_idstring"default"Organization to list ("all" for everything)

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

recommend_consolidation

Suggest merging duplicate or overlapping servers to reduce sprawl.

ParamTypeDefaultDescription
org_idstring"default"Organization to analyze

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.

ParamTypeDefaultDescription
server_urlstringrequiredURL or package name to check
transportstring"streamable-http"Transport to probe with
org_idstring"default"Check duplicates against this org

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

mcp-registry://serversAll registered servers with current health status

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
