## About

Plugolis is a directory of MCP servers and a collection of fixes for common MCP errors. The tools let an assistant search servers by query, category, client, status or transport, fetch install commands, ready-to-paste config JSON and required environment variables, and look up numbered fixes for error messages.

It runs as a hosted streamable HTTP endpoint at https://mcp.plugolis.com/mcp. All five tools are read-only. No sign-in or API key is needed.

## What it can do

- Search MCP servers by query, category, client, status or transport
- Get install command and config JSON for a server
- See required environment variables and maintenance status
- List server categories
- Find fixes by pasting an MCP error message
- Read full fix steps with cause and sources

## Tools (7)

- `search_servers`: Search the directory by query, category, client, status or transport; returns name, slug, category… (read-only)
- `get_server`: Full details for one server by slug: install command, config JSON, env vars, status and links. (read-only)
- `list_categories`: List every server category with its slug, server count and server slugs. (read-only)
- `search_fixes`: Find fixes for MCP errors from an error message or description, optionally filtered by client. (read-only)
- `get_fix`: Full fix by slug: the exact error, cause, numbered steps with code, and sources. (read-only)
- `list_setup_guides`: List the per-app MCP setup guides (Claude Desktop, Claude Code, Cursor, VS Code, Devin Desktop/Windsurf, ChatGPT, Codex, Gemini CLI) with their slugs and the date each was checked against official docs. (read-only)
- `get_setup_guide`: How to add MCP servers in one app: config file locations for macOS, Windows and Linux, the top-level JSON/TOML key, steps for local (stdio) and remote (URL) servers, tips, related fixes and official sources. (read-only)

## Example prompts

- "Find an MCP server for browser automation that works with Cursor."
- "Show me the config JSON to install the Time MCP server."
- "I get 'spawn npx ENOENT' in Claude Desktop on Windows. How do I fix it?"
- "List all MCP server categories and which servers are in each."

## Install

### Claude Code

1. Run this in a terminal, in your project folder:

```bash
claude mcp add --transport http plugolis https://mcp.plugolis.com/mcp
```

2. Start Claude Code and type `/mcp`. **plugolis** should show as connected.

Add `--scope user` to make it available in every project, not just this one.

### Claude Desktop

1. Open **Customize → Connectors**, click **+ Add**, then **Add custom connector**.

2. Name it **Plugolis** and paste this URL:

```url
https://mcp.plugolis.com/mcp
```

3. Click **Add**. Its tools appear in the chat’s tools menu.

Claude Desktop’s JSON config file only starts local servers. Remote servers go through Connectors, and connectors you add on claude.ai show up here too.

### claude.ai

1. Open the connector form on claude.ai. This button fills in the name and URL for you:

[Add to claude.ai](<https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=Plugolis&connectorUrl=https%3A%2F%2Fmcp.plugolis.com%2Fmcp>) (opens connector settings)

2. Check that the URL reads `https://mcp.plugolis.com/mcp` and click **Add**.

3. Turn it on in a chat from the tools menu.

Free plans allow one custom connector. On Team and Enterprise plans an owner adds it under **Organization settings → Connectors**.

### ChatGPT

1. On chatgpt.com, go to **Plugins**, select **+**, then **Add custom MCP server**.

2. Enter a name for the server.

3. Under **Connection**, paste `https://mcp.plugolis.com/mcp` as the server URL, then for authentication choose **No authentication**.

4. Check **I understand and want to continue**, then select **Create as a plugin**.

Whether you can add a custom MCP server depends on your ChatGPT plan and your workspace permissions (in Business workspaces, admins and owners can).

### Cursor

[Add to Cursor](<https://cursor.com/install-mcp?name=plugolis&config=eyJ1cmwiOiJodHRwczovL21jcC5wbHVnb2xpcy5jb20vbWNwIn0%3D>) (opens Cursor)

Or add it by hand to `~/.cursor/mcp.json` (all projects) or `.cursor/mcp.json` (this project):

`mcp.json`:

```json
{
  "mcpServers": {
    "plugolis": {
      "url": "https://mcp.plugolis.com/mcp"
    }
  }
}
```

### VS Code

[Install in VS Code](<https://vscode.dev/redirect/mcp/install?name=plugolis&config=%7B%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A%2F%2Fmcp.plugolis.com%2Fmcp%22%7D>) (opens VS Code)

Or from a terminal:

```bash
code --add-mcp '{"name":"plugolis","type":"http","url":"https://mcp.plugolis.com/mcp"}'
```

Or commit it to the repo in `.vscode/mcp.json`:

`.vscode/mcp.json`:

```json
{
  "servers": {
    "plugolis": {
      "type": "http",
      "url": "https://mcp.plugolis.com/mcp"
    }
  }
}
```

### Devin Desktop

1. Add it to `~/.config/devin/mcp_config.json` (macOS and Linux) or `%APPDATA%\devin\mcp_config.json` (Windows):

`mcp_config.json`:

```json
{
  "mcpServers": {
    "plugolis": {
      "serverUrl": "https://mcp.plugolis.com/mcp"
    }
  }
}
```

2. Refresh the MCP server list in Cascade.

Devin Desktop is the new name for Windsurf. It reads `serverUrl` (or `url`) for remote servers.

### Codex

```bash
codex mcp add plugolis --url https://mcp.plugolis.com/mcp
```

Or edit `~/.codex/config.toml` directly:

`config.toml`:

```toml
[mcp_servers.plugolis]
url = "https://mcp.plugolis.com/mcp"
```

### Gemini CLI

```bash
gemini mcp add --transport http plugolis https://mcp.plugolis.com/mcp
```

This adds it to the current project. Add `-s user` to use it everywhere.

### Any client

Most clients accept this shape. Some name the URL field differently: `serverUrl` in Devin Desktop, `httpUrl` in Gemini CLI’s settings file.

```json
{
  "mcpServers": {
    "plugolis": {
      "type": "http",
      "url": "https://mcp.plugolis.com/mcp"
    }
  }
}
```

Zed puts servers under `context_servers` in its settings. Cline needs `"type": "streamableHttp"`, or it assumes SSE.

Client only starts local servers? Bridge it with `npx -y mcp-remote https://mcp.plugolis.com/mcp`.
