Memstack Automation Hosted Mcp Catalog

About this prompt

Use when the user says 'what MCP servers', 'find an MCP for', 'hosted MCP', 'list MCP servers', 'MCP catalog', 'available MCP tools', or needs to discover zero-setup hosted MCP servers they can use immediately. Do NOT use for building MCP servers or configuring local MCP.

Prompt body

# Hosted MCP Catalog — Finding hosted MCP servers...
*Reference guide for zero-setup hosted MCP servers that require no API keys, no local install — just point any MCP client at the URL.*

## Activation

| Trigger | Status |
|---------|--------|
| User says "what MCP servers" or "find an MCP for" | ACTIVE |
| User says "hosted MCP" or "MCP catalog" | ACTIVE |
| User says "available MCP tools" or "list MCP servers" | ACTIVE |
| User wants to BUILD an MCP server | NOT this skill — use mcp-builder |
| User wants to configure local MCP | NOT this skill — check .mcp.json docs |

## Context Guard

- Do NOT use for building MCP servers (that's mcp-builder Pro skill)
- Do NOT use for local MCP server configuration
- Do NOT use for debugging MCP connection issues
- This skill ONLY helps discover and connect to hosted MCP endpoints

## How Hosted MCP Works

Hosted MCP servers run remotely — no local install needed. Add the URL to your MCP client config and the tools are available immediately.

**In Claude Code** — add to `.mcp.json`:
```json
{
  "mcpServers": {
    "server-name": {
      "type": "url",
      "url": "https://example.com/mcp"
    }
  }
}
```

**In Claude Desktop** — add to `claude_desktop_config.json`:
```json
{
  "mcpServers": {
    "server-name": {
      "url": "https://example.com/mcp"
    }
  }
}
```

## Catalog: Official Platform MCP Servers

These are maintained by major platforms and generally stable:

| Server | URL | Tools | Use Case |
|--------|-----|-------|----------|
| Vercel | `https://mcp.vercel.com` | Deploy, logs, env vars, projects | Vercel deployment management |
| Supabase | `https://mcp.supabase.com/mcp` | DB queries, migrations, RLS | Database management |
| Sentry | `https://mcp.sentry.dev/mcp` | Issues, errors, performance | Error tracking |
| Stripe | `https://mcp.stripe.com` | Payments, customers, invoices | Payment processing |
| Linear | `https://mcp.linear.app/mcp` | Issues, projects, cycles | Project management |
| Slack | `https://mcp.slack.com/mcp` | Messages, channels, search | Team communication |
| Greptile | `https://api.greptile.com/mcp` | Codebase search, understanding | Code intelligence |

**Note:** Most official servers require OAuth authentication on first use. Claude Code handles this automatically — you'll get a browser prompt to authorize.

## How to Choose

When the user needs an MCP server, help them find the right one:

### Step 1: Identify the need

| User wants to... | Recommended MCP |
|-------------------|-----------------|
| Query a database | Supabase |
| Track errors/bugs | Sentry |
| Deploy code | Vercel |
| Process payments | Stripe |
| Manage issues/tickets | Linear |
| Send team messages | Slack |
| Search codebases | Greptile |

### Step 2: Add to config

Generate the `.mcp.json` entry for the chosen server:

```json
{
  "mcpServers": {
    "<server-name>": {
      "type": "url",
      "url": "<server-url>"
    }
  }
}
```

### Step 3: Test the connection

After adding, restart Claude Code and verify:
1. The server appears in the MCP tools list
2. Authentication completes (if required)
3. A simple tool call succeeds

## Discovery Resources

When the catalog above doesn't cover the user's need:

| Resource | URL | Description |
|----------|-----|-------------|
| Anthropic MCP Registry | https://github.com/modelcontextprotocol/servers | Official MCP server list |
| Smithery | https://smithery.ai | MCP server marketplace |
| MCP.so | https://mcp.so | Community MCP directory |
| Glama | https://glama.ai/mcp/servers | Curated MCP catalog |

## Output Template

```
MCP Server: [name]
URL: [endpoint]
Auth: [OAuth / API key / None]
Tools available: [list of key tools]
Config to add to .mcp.json:

{
  "mcpServers": {
    "[name]": {
      "type": "url",
      "url": "[endpoint]"
    }
  }
}

Restart Claude Code after adding.
```

## Disambiguation

- "what MCP servers" / "find an MCP for" / "hosted MCP" = Hosted MCP Catalog
- "build an MCP server" / "create MCP tools" = mcp-builder (not this skill)
- "MCP not connecting" / "MCP error" = Debug directly (not this skill)
- "what tools do I have" = Check current MCP config (not this skill)
