Configuration

🔌 Connect to Client

Use this URL to configure your MCP client (Cursor, Claude Desktop, etc.):

https://mcp.atexplore.social/mcp

💻 Claude Code (Command Line)

If you're using Claude Code, add the server with this simple command:

claude mcp add --transport http at-explore https://mcp.atexplore.social/mcp

Verify it's connected with: claude mcp list

🖥 Local STDIO Mode (Write Operations)

STDIO mode runs the MCP server locally and enables write operations — creating, updating, and deleting records, and publishing posts. Authentication is performed via the login tool using Bluesky OAuth.

Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "at-explore": {
      "command": "npx",
      "args": ["-y", "at-explore-mcp"]
    }
  }
}

Restart Claude Desktop after saving. Then use the login tool to authenticate before using write operations.
