Each tool has a clearly distinct purpose: fetchDoc retrieves and parses documents, invokeOpenRPC handles structured RPC calls, and setAuth manages authentication. There is no overlap in functionality, and the descriptions make their unique roles explicit.

All tools follow a consistent 'anp.verbNoun' pattern (anp.fetchDoc, anp.invokeOpenRPC, anp.setAuth), using snake_case for multi-word names. This predictable naming scheme enhances readability and agent usability.

With only 3 tools, the server feels slightly thin but reasonable for its bridging purpose. It covers core operations (fetch, invoke, auth) without bloat, though additional utilities might be expected in a bridge server. The count is appropriate but minimal.

The tools provide essential coverage for interacting with ANP ecosystems: fetching documents, invoking RPC methods, and setting authentication. Minor gaps might include tools for managing sessions or handling errors, but the core workflow is well-supported without dead ends.
