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:
- The server appears in the MCP tools list
- Authentication completes (if required)
- 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)
