Bluesky Context Server

A Model Context Protocol (MCP) server that enables MCP clients like Claude Desktop to interact with Bluesky. Query your profile, search posts, get your timeline, and more directly from your AI assistant.

Prerequisites

• Runtime: Either Bun or Node.js v22.6.0+
• A Bluesky account

Setup

1. Get Your Bluesky Credentials

You'll need two pieces of information from your Bluesky account:

BLUESKY_IDENTIFIER

This is your Bluesky handle (username). It can be in either format:

• username.bsky.social (e.g., alice.bsky.social)
• @username.bsky.social (e.g., @alice.bsky.social)

BLUESKY_APP_KEY

This is an App Password, which is different from your regular Bluesky password. To create one:

1. Go to Bluesky Settings
2. Navigate to "Privacy and Security" → "App Passwords"
3. Click "Add App Password"
4. Give it a name (e.g., "MCP Server")
5. Copy the generated password (it looks like xxxx-xxxx-xxxx-xxxx)

⚠️ Important: Use the App Password, not your regular account password!

2. Installation

Option A: Installing via Smithery (Recommended)

To install Bluesky Context Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @laulauland/bluesky-context-server --client claude

Then add your credentials to the generated configuration.

Option B: Manual Installation

1. Clone or download this repository
2. Configure your Claude Desktop app to use the MCP server:

Using Bun:

// ~/Library/Application Support/Claude/config.json (macOS)
// %APPDATA%/Claude/config.json (Windows)
{
	"mcpServers": {
		"bluesky": {
			"command": "/Users/your-username/.bun/bin/bun",
			"args": [
				"/path/to/bluesky-context-server/packages/server/bin/index.ts"
			],
			"env": {
				"BLUESKY_APP_KEY": "your-app-password-here",
				"BLUESKY_IDENTIFIER": "your-handle.bsky.social"
			}
		}
	}
}

Using Node.js:

// ~/Library/Application Support/Claude/config.json (macOS)
// %APPDATA%/Claude/config.json (Windows)
{
	"mcpServers": {
		"bluesky": {
			"command": "node",
			"args": [
				"--experimental-strip-types",
				"/path/to/bluesky-context-server/packages/server/bin/index.ts"
			],
			"env": {
				"BLUESKY_APP_KEY": "your-app-password-here",
				"BLUESKY_IDENTIFIER": "your-handle.bsky.social"
			}
		}
	}
}
