Retro Diffusion Pixel Art vs Emilia Protocol
In-depth architectural comparison of the Retro Diffusion Pixel Art and Emilia Protocol MCP servers. Compare execution transports, security boundaries, tool capabilities, quality scores, and ready-to-paste client installation snippets for Claude, Cursor, Windsurf, and VS Code.
At a Glance & Executive Verdict
Retro Diffusion Pixel Art
Security · Remote HTTP/SSE
Quality: 53/100 (Good) | Auth: No auth required
Emilia Protocol
Security · Local stdio
Quality: 71/100 (Great) | Auth: No auth required
Verdict Summary: Choose Retro Diffusion Pixel Art if you need specialized Security tools running via a hosted cloud SSE transport. Choose Emilia Protocol if your workspace requires Security integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Retro Diffusion Pixel Art when:
You need dedicated capabilities in the Security domain.
You prefer remote streaming HTTP/SSE transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Generate authentic pixel art - sprites, animations, and tilesets - from any MCP client
Human sign-off + trust receipts for AI agents: requires a named human's approval before an irreversible action (payment release, record change, deploy), then mints an offline-verifiable Ed25519 Trust Receipt. Also exposes trust profiles, receipt verification, disputes, and delegation. Apache-2.0; policy engine formally verified. Install: npx -y @emilia-protocol/mcp-server.

Tools & Capabilities Breakdown
Retro Diffusion Pixel Art Tools (20)
create_inference
Generate images, animations (GIF/sprite sheet), or tilesets. Returns hosted URLs and a recovery `request_id`; prefer RD Pro styles for top quality
get_inference_result
Recover or refresh signed output URLs for a successful synchronous generation without generating or charging again
start_inference_job
Start generation as an async job — recommended for animations and batches
get_inference_job
Poll an async job for status and results
list_inference_jobs
List your recent async jobs — recover a `task_id` after a lost submission response instead of re-submitting and double-charging
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Retro Diffusion Pixel Art is categorized under Security and uses a remote streaming HTTP/SSE transport. In contrast, Emilia Protocol belongs to Security using local stdio subprocess. Select Retro Diffusion Pixel Art when you need capabilities focused on security and Emilia Protocol when you require tools for security.

Emilia Protocol Tools (3)
ep_guard_action
Request authorization before an irreversible action: payments, wire transfers, fund releases, deletions, record or account changes, or sending messages with real-world effect. Submits the exact action for policy evaluation and human authorization. This MCP tool does not itself sit at the executor choke point: even after approval, the executor MUST match the returned action_hash and atomically consume the receipt before effect. If BLOCKED, poll ep_check_signoff with the receipt_id.
ep_check_signoff
Poll a pending authorization after ep_guard_action returns BLOCKED. Pass the receipt_id. Returns PENDING, APPROVED_PENDING_CONSUME, CONSUMED, or DENIED. Approval alone is not permission to execute: the executor must match action_hash and atomically consume the receipt at its own choke point.
ep_verify_receipt
Ask the configured EMILIA service to verify a stored trust receipt and report its hash and anchor status. Read-only, but not an offline verifier: the result is the service response for the supplied receipt_id.
