Scored across 4 tools
Each tool has a clearly distinct purpose: jwt_analyze for vulnerability assessment, jwt_bruteforce for secret cracking, jwt_decode for raw decoding, and jwt_generate for token creation. There is no overlap in functionality, making it easy for an agent to select the correct tool for a specific task.
All tool names follow a consistent 'jwt_' prefix with a descriptive action suffix (analyze, bruteforce, decode, generate), using snake_case uniformly. This predictable pattern enhances readability and reduces confusion for agents.
With 4 tools, the server is well-scoped for JWT auditing, covering essential operations like analysis, decoding, generation, and brute-forcing. Each tool earns its place without being too sparse or overwhelming, fitting typical use cases in this domain.
The toolset provides strong coverage for core JWT auditing tasks, including decode, generate, analyze, and brute-force. A minor gap exists in lacking a tool for verifying JWTs with known keys, which could be useful but is not critical for the stated purpose, as agents can work around this.
