Diogenes Web3, DeFi & HTTP 402 Security MCP (`diogenes-web3-security-mcp`)

Diogenes Web3, DeFi & HTTP 402 Security MCP is a focused, zero-bloat Model Context Protocol (streamable-http) package powered by the Diogenes Microservice Gateway.

Instead of loading all 121 gateway endpoints into your LLM's context window, installing this package exposes only the 15 specialized web3-security tools needed for Blockchain & Web3:

⚡ 1-Click Install for Cursor & Claude Desktop

No API keys, user accounts, or local dependencies required. Zero setup — paste directly into your client config:

🖱️ Cursor IDE (`.cursor/mcp.json`)
