MCP Discovery

Discovers and catalogs available MCP servers from registries, community sources, and local configurations.

Preloaded Skills

Always load before analysis:

• [skill:dotnet-advisor] -- routing and context
• [skill:mcp-health] -- validate discovered MCPs

Usage

# Discover all MCP servers
[mcp-discovery:find-all]

# Search MCP registry
[mcp-discovery:search <keyword>]

# Update local MCP config
[mcp-discovery:update-config]

# Show available MCPs
[mcp-discovery:list]

## MCP Registry Sources

### Official Registries

1. **MCP Registry (modelcontextprotocol.io)**
   - Official MCP server listings
   - Verified implementations
   - Community submissions

2. **Smithery Registry (smithery.ai)**
   - Curated MCP servers
   - Ratings and reviews
   - Installation guides

### Discovery Methods

#### From Official Registry

```bash
# Fetch MCP registry
https://registry.modelcontextprotocol.io/servers

# Parse and filter for .NET compatible
jq '.servers[] | select(.tags[] | contains("dotnet") or contains("csharp"))'
```text
#### From Smithery

```bash
# Query Smithery MCP catalog
https://smithery.ai/api/mcp-servers

# Filter by category
curl -s "https://smithery.ai/api/mcp-servers?category=development"
```text
### Local Discovery

#### From Package.json (Node.js projects)

```bash
# Check for MCP servers in devDependencies
jq '.devDependencies | keys[] | select(contains("mcp"))' package.json
```text
#### From Tool Configuration

```bash
# VS Code extensions
ls ~/.vscode/extensions/ | grep -i mcp

# Claude Code config
ls ~/.claude/ | grep -i mcp
```text
## Discovery Script

Add to hooks or commands:

```bash
# Inline mcp-discovery.sh: Discover available MCP servers
set -uo pipefail

DISCOVERED_MCP=


  -v curl >/dev/null 2>&1; 
  REGISTRY_DATA=$(curl -s --connect-timeout 5 \
     2>/dev/null ||  )

   [ -n  ]; 
    
    DISCOVERED_MCP=$(  | jq -c  2>/dev/null ||  )
  



LOCAL_MCPS=


  -v uvx >/dev/null 2>&1; 
  LOCAL_MCPS=$(  | jq )


  -v npx >/dev/null 2>&1; 
  LOCAL_MCPS=$(  | jq )

Add discovery to rulesync workflow:

Local tools should use stdio transport:

- Better performance (no HTTP overhead)
- Works offline
- Easier debugging



Cloud APIs should use http transport:

- No  installation required
- Automatic updates
- Scalable



Always validate discovered MCPs:

```bash

[mcp-health:check <new-mcp>]


[mcp-discovery: <new-mcp>]
```text


Pin MCP server versions  stability:

```json
{
  : {
    : {
      : ,
      : ,
      : [, , ]
    }
  }
}
```text\n\n## Troubleshooting Discovery



**Problem:** Registry unreachable

**Solutions:**

- Check network connectivity
- Try offline mode with cached registry
- Use  MCP servers only



**Problem:** MCP doesnChecking  available MCP servers...
