# Nebula MCP: Stellar Blockchain Wallet for AI Agents

> Nebula is an MCP server that gives any AI agent a real Stellar wallet — payments, yield, spending policy, and on-chain identity — in minutes.

Nebula is an MCP server that gives your AI agent a real Stellar blockchain wallet — no custodian, no intermediary, no human in the loop. Connect it to Claude Desktop, Claude Code, or any MCP-compatible framework in seconds, set your spending policy, and let your agent pay for APIs, earn yield on idle funds, and build on-chain reputation automatically.
