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.
| Param | Type | Default | Description |
|---|---|---|---|
name | string | required | Server name (e.g. "filesystem-mcp") |
url | string | required | Server URL or package name |
transport | string | "stdio" | "stdio", "sse", or "streamable-http" |
description | string | "" | What this server does |
org_id | string | "default" | Organization for multi-tenant grouping |
tools | string[] | [] | Tool names this server provides |
health_check
Check server health. Probes HTTP endpoints, measures latency, tracks uptime over time.
| Param | Type | Description |
|---|---|---|
server_id | string | Server 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.
| Param | Type | Default | Description |
|---|---|---|---|
org_id | string | "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.
| Param | Type | Default | Description |
|---|---|---|---|
server_ids | string[] | required | Server IDs to include |
target_client | string | "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.
| Param | Type | Default | Description |
|---|---|---|---|
org_id | string | "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.
| Param | Type | Default | Description |
|---|---|---|---|
org_id | string | "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.
| Param | Type | Default | Description |
|---|---|---|---|
server_url | string | required | URL or package name to check |
transport | string | "streamable-http" | Transport to probe with |
org_id | string | "default" | Check duplicates against this org |
Returns: reachability, latency, TLS status, CORS headers, duplicate risk, and install recommendation (OK / CAUTION / DO NOT INSTALL).
Resources
| URI | Description |
|---|---|
mcp-registry://servers | All 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
