Emilia Protocol vs Supply Chain Guard

A side-by-side look at the Emilia Protocol and Supply Chain Guard MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.

Emilia Protocol logoEmilia ProtocolSecurity · Local subprocess (stdio)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.71GreatAuth: no auth requiredSupply Chain Guard logoSupply Chain GuardSecurity · Local subprocess (stdio)Supply-chain malware scanner and MCP server: vet packages in 15 ecosystems before install, offline.51GoodAuth: no auth required

Verdict: choose Emilia Protocol for security work as a local process; choose Supply Chain Guard for security as a local process. You can also run both side by side in one mcpServers block.

Tools & capabilities

Emilia Protocol tools 3

  • ep_guard_actionRequest 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_signoffPoll 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_receiptAsk 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.
