Bluesky MCP server

This server enables you to connect Claude to Bluesky, allowing it to query Bluesky instances through the Model Context Protocol (MCP). With this integration, Claude can access and interact with content from the Bluesky social network.

Installation Options

Via Smithery

The easiest way to install the Bluesky Context Server is using Smithery:

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

Manual Installation

If you prefer to install manually:

1. Download the code to your local machine
2. Configure the Claude Desktop app to use the MCP server

Configuration

After installation, you'll need to configure the Claude Desktop app by editing its configuration file:

// ~/Library/Application Support/Claude/config.json
{
	"mcpServers": {
		"bluesky": {
			"command": "/Users/laurynas-fp/.bun/bin/bun",
			"args": [
				"<path_to_this_directory>/bluesky-context-server/index.ts"
			],
			"env": {
				"BLUESKY_APP_KEY": "",
				"BLUESKY_IDENTIFIER": ""
			}
		}
	}
}

Configuration Parameters

Make sure to update the following in your configuration:

• Replace <path_to_this_directory> with the actual path where you stored the Bluesky Context Server
• Add your Bluesky application key to the BLUESKY_APP_KEY field
• Add your Bluesky identifier (typically your handle) to the BLUESKY_IDENTIFIER field

Using the Bluesky Context Server

Once properly configured, Claude will be able to:

• Query content from Bluesky
• Access Bluesky posts and interactions
• Retrieve information from the Bluesky network

You can interact with Claude normally, and it will now have the capability to reference and include Bluesky content in its responses when relevant.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "bluesky" '{"command":"bun","args":["index.ts"],"env":{"BLUESKY_APP_KEY":"","BLUESKY_IDENTIFIER":""}}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "bluesky": {
            "command": "bun",
            "args": [
                "index.ts"
            ],
            "env": {
                "BLUESKY_APP_KEY": "",
                "BLUESKY_IDENTIFIER": ""
            }
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "bluesky": {
            "command": "bun",
            "args": [
                "index.ts"
            ],
            "env": {
                "BLUESKY_APP_KEY": "",
                "BLUESKY_IDENTIFIER": ""
            }
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
