Insumer

Insumer is an open-source MCP server that provides a condition-based access infrastructure for blockchain wallets, designed for AI agents and workflow automation. It allows users to request and receive cryptographically signed boolean attestations about wallet conditions (such as token balances or account status) across 37 blockchains, without revealing balances or user identity. The tool is aimed at developers, AI platforms, commerce applications, and compliance use cases that require automated verification of on-chain conditions, merchant discovery, and trust profile attestations.
