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

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

Tests
