[](SECURITY.md)
A comprehensive Model Context Protocol (MCP) server that provides LLMs with direct access to the AT Protocol ecosystem, enabling seamless interaction with Bluesky and other AT Protocol-based social networks.
**Supports both authenticated and unauthenticated modes** - Start immediately with public data access (search posts, view profiles), or add authentication for full functionality (write operations, private data, feeds).
> **New in v0.1.1**: Batch operations for bulk actions, advanced analytics and insights, intelligent content discovery, and conversation context tracking for better LLM awareness across interactions!
## Architecture
This MCP server acts as a bridge between LLM clients and the AT Protocol ecosystem:
```
┌─────────────────┐
│ User │ "Search for posts about AI"
└────────┬────────┘
│ Natural Language
▼
┌─────────────────┐
│ LLM Client │ (Claude Desktop, etc.)
│ (MCP Client) │
└────────┬────────┘
│ MCP Protocol (JSON-RPC 2.0)
▼
┌─────────────────┐
│ This Server │ AT Protocol MCP Server
│ (MCP Server) │ - Tools, Resources, Prompts
└────────┬────────┘
│ AT Protocol API
▼
┌─────────────────┐
│ AT Protocol │ Bluesky, Custom PDS, etc.
│ Ecosystem │
└─────────────────┘
```
**Key Point**: Users don't interact with this server directly. Instead, they talk to their LLM client in natural language, and the LLM client uses this MCP server to access AT Protocol functionality.
## Features
### New in v0.1.1
- **Batch Operations**: Perform multiple operations in a single call (follow/like/repost up to 25 items at once)
- **Analytics & Insights**: Analyze engagement patterns, network connections, and get content strategy recommendations
- **Content Discovery**: Find similar users, trending topics, and influential voices in your areas of interest
- **Conversation Context**: Track conversation state across LLM interactions for better context awareness
### Core Features
- **Unauthenticated Mode**: Access public data without any setup - view basic profiles and manage OAuth flows
- **Optional Authentication**: Enable full functionality with app passwords or OAuth for write operations, feeds, and private data
- **Complete AT Protocol Integration**: Full implementation using official `@atproto/api`
- **MCP Server Compliance**: Built with `@modelcontextprotocol/sdk` following MCP specification
- **Type-Safe**: Written in TypeScript with strict type checking
- **Comprehensive Tools**: 57 MCP tools for social networking operations
- **Real-time Support**: WebSocket connections for live data streams with intelligent filtering and keyword monitoring
- **Rate Limiting**: Built-in respect for AT Protocol rate limits
- **Extensible**: Modular architecture for easy customization
## Who Is This For?
### Primary Audience: LLM Clients
This is an **MCP (Model Context Protocol) server** designed to be consumed by **LLM clients** such as:
- Claude Desktop
- Other MCP-compatible AI assistants
- Custom LLM applications using the MCP SDK
**How it works:**
```
User → LLM Client (Claude Desktop) → MCP Protocol → This Server → AT Protocol → Bluesky
```
Users interact with their LLM client in natural language (e.g., "search for posts about AI"), and the LLM client uses this MCP server to fulfill those requests by calling the appropriate tools via the MCP protocol.
### Secondary Audience: Developers
This project is also for developers who want to:
- **Deploy** the MCP server for their LLM clients to connect to
- **Extend** the server with custom MCP tools and resources
- **Contribute** to the open-source project
### This Is NOT:
- A direct-use REST API or SDK for application developers
- A JavaScript/TypeScript library to import into your app
- An end-user application
If you're building an application that needs AT Protocol functionality, you should either:
1. Use the official `@atproto/api` package directly, OR
2. Build an LLM-powered application that uses this MCP server through an LLM client
## Installation
```bash
npm install -g atproto-mcp
```
Or use with npx:
```bash
npx atproto-mcp
```
## Quick Start
### Option 1: Unauthenticated Mode (Recommended for most use cases)
**Perfect for LLM clients that need to access public AT Protocol data:**
1. **Configure your LLM client** (e.g., Claude Desktop) to launch the MCP server:
Add to your LLM client's MCP configuration:
```json
{
"mcpServers": {
"atproto": {
"command": "npx",
"args": ["atproto-mcp"]
}
}
}
```
2. **Start your LLM client** - it will automatically launch the MCP server
3. **Interact in natural language** - Ask your LLM to search posts, view profiles, etc.
**What your LLM can do in unauthenticated mode:**
- View user profiles (`get_user_profile` - works without auth, provides additional viewer-specific data when authenticated)
- Manage OAuth authentication flows (`start_oauth_flow`, `handle_oauth_callback`, `refresh_oauth_tokens`, `revoke_oauth_tokens`)
**Note:** The following features require authentication:
- Searching posts and hashtags (`search_posts`) - **API changed in 2025 to require authentication**
- Viewing follower/following lists (`get_followers`, `get_follows`)
- Browsing feeds and threads (`get_thread`, `get_custom_feed`, `get_timeline`)
- All write operations (create, like, repost, follow, etc.)
- Resources (timeline, profile, notifications) - these are listed but will return an error when accessed without authentication
- Prompts (content composition, reply templates) - these are listed but will return an error when accessed without authentication
**Important:** All tools, resources, and prompts are listed by the MCP server regardless of authentication state. Tools and resources that require authentication will return a clear error message when called without proper credentials.
### Option 2: Authenticated Mode (For full functionality)
**Enable write operations and private data access for your LLM:**
1. **Configure your LLM client** with AT Protocol credentials:
```json
{
"mcpServers": {
"atproto": {
"command": "npx",
"args": ["atproto-mcp"],
"env": {
"ATPROTO_IDENTIFIER": "your-handle.bsky.social",
"ATPROTO_PASSWORD": "your-app-password"
}
}
}
}
```
2. **Start your LLM client** - it will launch the authenticated MCP server
**What your LLM can do in authenticated mode:**
- Create, edit, and delete posts
- Follow/unfollow users
- Like and repost content
- Access personalized timelines and notifications
- Manage lists and moderation settings
## Available Tools

```bash
export ATPROTO_IDENTIFIER="your-handle.bsky.social"
export ATPROTO_PASSWORD="your-app-password"
atproto-mcp
```
### OAuth (Production)
```bash
export ATPROTO_CLIENT_ID="your-client-id"
export ATPROTO_CLIENT_SECRET="your-client-secret"
atproto-mcp --auth oauth
```

## Security
Security is a top priority for this project. Please review our security practices and policies:
### Security Best Practices
**Before deploying to production:**
1. **Change Default Passwords**
- Set `GRAFANA_ADMIN_PASSWORD` environment variable (don't use default)
- Configure Redis password if using Redis
- Generate strong random keys for `SECURITY_SECRET_KEY`
2. **Configure CORS Properly**
- Replace wildcard `*` origins with specific domains
- Set `CORS_ORIGINS` in your environment configuration
- Example: `CORS_ORIGINS=https://yourdomain.com,https://app.yourdomain.com`
3. **Secure Your Credentials**
- Never commit `.env` files to version control
- Use app passwords instead of main account passwords
- Rotate credentials regularly
- Use secret management systems in production (AWS Secrets Manager, HashiCorp Vault, etc.)
4. **Network Security**
- Use HTTPS in production
- Configure `TRUSTED_PROXIES` if behind a reverse proxy
- Enable rate limiting
- Restrict access to internal services (Redis, Prometheus, Grafana)
5. **Keep Dependencies Updated**
```bash
pnpm audit
pnpm update
```
### Reporting Security Vulnerabilities
If you discover a security vulnerability, please review our [Security Policy](SECURITY.md) for responsible disclosure guidelines.
**Do not open public issues for security vulnerabilities.** Instead, send me a message privately.
### Security Features
- Input validation and sanitization
- Rate limiting and abuse prevention
- Credential redaction in logs
- Non-root Docker containers
- HTTPS support for AT Protocol
- Error sanitization to prevent information leakage
