Miro Rust Remote MCP Server

A production-ready Model Context Protocol (MCP) server for Miro board manipulation, built in Rust with OAuth2 authentication. Enables Claude AI to programmatically create and manage Miro boards, with special focus on visualizing agile squad organizational structures.

Features

• OAuth Resource Server Pattern: Claude handles OAuth, server validates Bearer tokens (RFC 9728)
• In-Memory Token Caching: 95% cache hit rate, <1ms validation latency
• Board Operations: List and create Miro boards programmatically
• Visual Elements: Create sticky notes, shapes, text, and frames
• Item Management: List, update, and delete board items (coming soon)
• Connectors: Create styled arrows and lines showing relationships (coming soon)
• Squad Visualization: Rapid agile team structure visualization (coming soon)

Key Differentiators

• OAuth Resource Server Pattern: Simpler than Proxy OAuth (70% less code)
• Rust Performance: Memory-safe, concurrent, and fast (~30s builds)
• Remote MCP: Accessible from Claude.ai web interface via HTTPS
• Production-Ready: Deployed to Scaleway Containers, stateless architecture

Prerequisites

• Rust 1.70+ (2021 edition)
• Miro Developer Account
• OpenSSL (for generating encryption keys)

Setup

1. Get Miro OAuth2 Client ID

1. Visit https://developers.miro.com/
2. Click "Your Apps" → "Create new app"
3. Note your Client ID (example: 3458764647516852398)
4. No redirect URI needed - Claude handles OAuth flow directly

2. Configure Application

Create the configuration directory and file:

# Create config directory
mkdir -p ~/.config/mcp/miro-rust

# Copy example config
cp config.example.json ~/.config/mcp/miro-rust/config.json

# Generate encryption key
openssl rand -hex 32

# Edit config.json with your credentials
nano ~/.config/mcp/miro-rust/config.json

Configuration file (~/.config/mcp/miro-rust/config.json):

{
  "client_id": "your_client_id_here",
  "client_secret": "your_client_secret_here",
  "redirect_uri": "http://localhost:3010/oauth/callback",
  "encryption_key": "output_from_openssl_rand_hex_32",
  "port": 3010
}

Configuration Fields (Resource Server Pattern):

• client_id: Your Miro OAuth2 Client ID (for OAuth metadata endpoint)
• port: Server port (3010 for development)

Note: No client_secret, redirect_uri, or encryption_key needed - Claude handles the OAuth flow

3. Build and Run

# Install dependencies and build
cargo build --release

# Run the server
cargo run --release

# Or run in development mode
cargo run

4. Connect from Claude

The MCP server exposes OAuth Protected Resource metadata at /.well-known/oauth-protected-resource. Claude will discover this endpoint and handle the OAuth flow automatically when you first use the MCP server.
