Which integrations are available for this server?

Provides tools to interact with the Arcium encrypted computation network on Solana, enabling AI agents to explore network components, manage encryption, track computations, and execute encrypted applications such as coinflip, rock-paper-scissors, sealed bids, and private votes.

How do I use arcium-mcp?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@arcium-mcp list all MXE execution environments" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

arcium-mcp — MCP Server for Arcium Confidential Computing

Connects AI agents (Claude, GPT, any MCP client) to the Arcium encrypted computation network on Solana.

Status

Alpha. Full MCP server with 19 tools across 4 categories. Network Explorer and Encryption Engine use the real Arcium SDK. App Templates implement the full encrypt → submit → await → decrypt pipeline (requires deployed MXE programs and wallet). Supports both stdio and HTTP/SSE transport.
