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.

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.

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
Tests
npm test
