A free, open-source (MIT) secret broker for AI agents: agents reference secrets by name and Portunus injects the value only at the execution boundary (env var, file or exec argv), never into the model's context. Ships as a stdio MCP server and CLI with local-encrypted, GCP Secret Manager and read-only Chrome saved-login backends.

A local-first contact management MCP server with SQLite storage and Google Contacts sync, enabling AI agents to upsert, search, log interactions, and surface follow-ups for relationships.
