Reference guide for zero-setup hosted MCP servers that require no API keys, no local install — just point any MCP client at the URL.
| 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 |
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:
{
"mcpServers": {
"server-name": {
"type": "url",
"url": "https://example.com/mcp"
}
}
}
In Claude Desktop — add to claude_desktop_config.json:
{
"mcpServers": {
"server-name": {
"url": "https://example.com/mcp"
}
}
}
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.
When the user needs an MCP server, help them find the right one:
| 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 |
Generate the .mcp.json entry for the chosen server:
{
"mcpServers": {
"<server-name>": {
"type": "url",
"url": "<server-url>"
}
}
}
After adding, restart Claude Code and verify:
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 |
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.
npx claudepluginhub cwinvestments/memstack --plugin memstackGuides integration of Model Context Protocol (MCP) servers into Claude Code plugins via .mcp.json or plugin.json for external service tools, with scope management (local, project, user).
Discovers, recommends, installs, and verifies MCP servers based on detected project stack, handling package installation, configuration, env vars, and testing.
Manages MCP servers by discovering, analyzing, and executing tools/prompts/resources via CLI scripts. Use for integrations, capability discovery, tool filtering, and context bloat resolution.
