Model Context Protocol (MCP) Server

2. Official Server Endpoints

The Glubler MCP infrastructure operates with both hosted remote streaming endpoints and standard OAuth 2.1 discovery services:

Service	URL / Endpoint	Specification
MCP Server (SSE)	https://mcp.glubler.com/sse	Server-Sent Events (SSE) remote transport
Messages Endpoint	https://mcp.glubler.com/messages	JSON-RPC 2.0 message handler
Protected Resource Metadata	https://glubler.com/.well-known/oauth-protected-resource	RFC 9728 discovery
OAuth 2.1 Authorization Server	https://glubler.com/.well-known/openid-configuration	RFC 8414 discovery
Authorize Endpoint	https://glubler.com/connect/authorize	OAuth 2.1 Code Flow + PKCE (S256)
Token Endpoint	https://glubler.com/connect/token	Token exchange & refresh

3. OAuth 2.1 & PKCE Authentication Flow

For cloud AI platforms such as OpenAI and Anthropic, Glubler implements the official OAuth 2.1 specification with mandatory Proof Key for Code Exchange (PKCE S256):

• PKCE Protection: Protects against authorization code interception attacks without requiring client secrets on public clients.
• Isolated Grants: Normal user sessions on www.glubler.com remain independent; authorization is granted strictly to the AI client.
• Scope Control: The default scope mcp:all allows managing collections and bookmarks on behalf of the user.

4. Available MCP Tools

Once connected, the AI model has access to the following 10 structured tools:

Tool Name	Description	Plan Requirement
search_glubler_catalog	Search Glubler's database for existing websites, news sources, games, and tools.	Free
list_my_glublers	List all collections (glublers) and nested subglublers belonging to the authenticated account.	Free

get_public_glubler	View any public Glubler list using username and slugName (no auth required).	Free

6. Claude & Claude Desktop Configuration

Claude Desktop Configuration

Add the remote server directly to your claude_desktop_config.json:

{
  "mcpServers": {
    "glubler": {
      "url": "https://mcp.glubler.com/sse",
      "headers": {
        "Authorization": "Bearer YOUR_GLUBLER_TOKEN"
      }
    }
  }
}

7. Desktop Clients (Chatbox, OpenCowork, Cursor)

For Chatbox or any desktop AI client supporting Remote MCP over HTTP/SSE:

1. Open the MCP Settings modal.
2. Set Type to Remote (http/sse).
3. Set Protocol to Legacy (Standard SSE transport).
4. Set URL to https://mcp.glubler.com/sse.
5. Set HTTP Header to Authorization=Bearer YOUR_GLUBLER_TOKEN.
6. Click Connect, then Save.

8. Free vs. Pro Plan Enforcement

Glubler provides generous capabilities on the Free plan, while advanced nested hierarchy is reserved for Pro members:

• Free / Standard Plan: Unlimited top-level Glubler collections, catalog search, gluing websites, batch imports, social sharing, and renaming.
• Pro Plan ($4.32/mo): Nested Subglublers (up to 7 levels deep). If a Free plan user asks an AI to create a subglubler, the server returns PRO_PLAN_REQUIRED, and the AI guides the user to upgrade at glubler.com/settings.
