New Feature: Archon MCP Server - Local wallets for all AI Agents

[Flaxscrip]

Summary

We've built an MCP (Model Context Protocol) server that gives AI agents like Claude Desktop their own decentralized identity. This enables AI-to-AI encrypted communication, verifiable credentials, and cryptographic proof of identity — all with local wallet storage.

The Problem

AI agents are proliferating across every platform, but they lack identity infrastructure:

• API keys leak (Moltbook, Feb 2026: 1.5M keys exposed)
• No way to verify who an agent is or who controls it
• No encrypted communication between agents
• No credential-based authorization for agent actions

The Solution

The Archon MCP Server provides:

Capability	Description
🔐 DID Creation	Each agent gets a unique decentralized identifier
📬 Encrypted Messaging	DMail between agents (end-to-end encrypted)
🎫 Verifiable Credentials	Issue, hold, and present credentials
🔑 Local Wallet	Private keys never leave the user's machine
✅ Challenge/Response	Prove identity and verify others

• create_id, list_ids, get_current_id, set_current_id
• resolve_did
• send_dmail, list_dmail, read_dmail
• create_challenge, create_response, verify_response
• list_credentials, get_credential, accept_credential
• wallet_status, create_wallet

Configuration

Variable	Default	Description
ARCHON_PASSPHRASE	changeme	Wallet encryption
ARCHON_GATEKEEPER_URL	https://archon.technology	Gatekeeper endpoint
ARCHON_WALLET_DIR	~/.archon-mcp	Wallet location
ARCHON_REGISTRY	hyperswarm	Default registry

Benefits

For AI Agent Developers

• Drop-in identity for any MCP-compatible agent
• No infrastructure to run — just npx and configure
• Works with existing Archon ecosystem

For Enterprise

• Agents can prove authorization via credentials
• Audit trail via DID operations
• Self-hosted gatekeeper option

For the Ecosystem

• Standard identity layer for AI agents
• Interoperable with SSI/DID standards
• Positions Archon as infrastructure for AI identity

Next Steps

1. Create archetech/archon-mcp-server repository
2. Publish to npm as @archon-protocol/mcp-server
3. Add to archon.technology website
4. Register in MCP server directories
5. Announce to community

Excellent, I suggest you transfer your repo to Archetech org

@macterra - thank you for taking a look. This was late-nite "vibe" coded. The keymaster openapi made it pretty trivial though.
