SandBase CLI: MCP tool for Hermes Agent

Local MCP bridge that connects 25 AI clients, including Hermes Agent, to SandBase models and APIs

What SandBase CLI does

The package is published as @sandbaseai/cli and runs a local MCP bridge. After you approve a browser authorization once, each supported client can discover, inspect and run the SandBase models and APIs that are available to it. The GitHub release includes a verified catalog of 25 clients, and a read-only catalog --json command lets you check compatibility before signing in or changing any configuration. The repository description names Claude Code, Cursor, Codex, ChatGPT, Hermes and OpenClaw among the clients.

The README advertises more than 2,000 models and APIs, and the repository description lists OAuth and rollback. Installation is either an npx command that points at a GitHub release tarball, with its SHA-256 published for verification, or a Homebrew formula for macOS and Linux. The same organization also publishes a self-hosted agent runtime called SandBase Harness, an 88-skill pack, and a Codex plugin.
