Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions · remote - your agent's requests go to cnb.cz-agents.dev

endpoint auth accepted our unauthenticated MCP initialize - no credentials needed to connect

license MIT - declared in the repository

npm package @czagents/cnb - the @czagents scope differs from the repo owner (martinhavel); confirm it's the project's official package

registry vendor namespace dev.cz-agents - domain-verified with the official MCP registry

03 · What Cnb can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

An agent gets 2 documented tools, including get_rates, get_rate.
