EVDI is an end - to - end verifiable data infrastructure that provides digital identity and credential management for the AI agent ecosystem. It enables the authentication and trust establishment of AI agents through the Self - Sovereign Identity (SSI) model. The MCP Server, as an adapter for the SSI issuance service, exposes SSI operations as tools that can be called by AI models, supporting credential management and verification functions.

The MCP server is used to query, obtain details, and download electronic service invoices (NFSe) on the Brazilian National NFSe Portal through digital certificates, supporting automatic authentication and session management.
