⚡ Diogenes Sovereign Multi-Protocol AI Gateway & MCP Server

Zero API keys. Zero subscriptions. Instant pay-per-request intelligence for autonomous AI agents.
Settle via Bitcoin Lightning (L402), Solana USDC (x402), or Base USDC (MPP). Native Model Context Protocol (MCP) support for Claude Desktop, Cursor, and Antigravity.

🌟 Why Autonomous Agents Use Diogenes

1. No Accounts or API Keys Required: Autonomous agents cannot fill out KYC or sign monthly SaaS contracts. Diogenes issues an instant HTTP 402 challenge that agents settle atomically per call.

2. Multi-Protocol Settlement:

   • L402 (Lightning): Instant micro-satoshi payments via BOLT11 preimage verification.

   • x402 (Solana): Stateless HTTP 402 micropayments in USDC or SOL.

   • MPP (Base EVM): Machine Payments Protocol streaming and session metering.

3. Model Context Protocol (MCP) Native: Streamable JSON-RPC 2.0 server at https://diogenes-l402-gateway.corinth.workers.dev/mcp and tool manifest at /.well-known/mcp.json.

4. Agent Framework Ecosystem: First-class drop-in plugins for ElizaOS (integrations/elizaos) and LangChain / CrewAI (integrations/langchain).

5. Instant Zero-Token Demo Mode: Every single endpoint includes ?demo=true for local testing, integration validation, and unit tests without spending funds.

⚡ Integrations & Quickstart

1. Model Context Protocol (Claude Desktop / Cursor / Antigravity)

Add this to your Claude Desktop configuration (claude_desktop_config.json) or Cursor MCP settings:

{
  "mcpServers": {
    "diogenes": {
      "url": "https://diogenes-l402-gateway.corinth.workers.dev/mcp"
    }
  }
}

Verify streamable handshake with cURL:

curl -s -X POST "https://diogenes-l402-gateway.corinth.workers.dev/mcp" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc": "2.0", "id": 1, "method": "initialize", "params": {"protocolVersion": "2024-11-05"}}'

2. ElizaOS Agent Plugin (@elizaos/plugin-diogenes)

Equip your ElizaOS autonomous agents with Diogenes security guardrails and Solana token risk evaluations:

import { diogenesPlugin } from "./integrations/elizaos";

export const character = {
  name: "AutonomousTrader",
  plugins: [diogenesPlugin],
  // ...
};

3. LangChain & CrewAI Tools (integrations/langchain)

Import ready-to-use tools for Python agent workflows:

from integrations.langchain.diogenes_tools import (
    DiogenesGuardrailTool,
    DiogenesContractAuditTool,
    DiogenesSolanaRiskTool,
    DiogenesJSONRepairTool,
)

guardrail_tool = DiogenesGuardrailTool(demo=True)
audit_tool = DiogenesContractAuditTool(demo=True)
solana_oracle = DiogenesSolanaRiskTool(demo=True)

# Pre-execution safety gate
verdict = guardrail_tool.run(action="transfer 5 SOL to unknown recipient")
print(verdict)

4. Zero-Dependency Python SDK (diogenes_client.py)

Drop diogenes_client.py into your project:

from diogenes_client import DiogenesClient

client = DiogenesClient()

# 1. Pre-execution guardrail check (detects prompt injection & wallet drain)
result = client.guardrail_verify("rm -rf /", demo=True)
print(result)

# 2. Smart contract rugpull & honeypot audit
audit = client.contract_audit("contract Token { ... }", demo=True)
print(audit)

# 3. Solana SPL Token Risk & Freeze Authority Oracle
risk = client.solana_risk("EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v", demo=True)
print(risk)

5. cURL (Instant Demo Preview)

# Guardrail Security Gate
curl -X POST "https://diogenes-l402-gateway.corinth.workers.dev/api/v1/agent/guardrail-verify?demo=true" \
  -H "Content-Type: application/json" \
  -d '{"action": "check system safety"}'

# Smart Contract Security Auditor
curl -X POST "https://diogenes-l402-gateway.corinth.workers.dev/api/v1/agent/contract-audit?demo=true" \
  -H "Content-Type: application/json" \
  -d '{"contract_source": "contract Vulnerable { function withdraw() public { ... } }"}'
