Scored across 5 tools
Three tools revolve around Merkle-style proofs (zero_knowledge_merkle_membership_proof, merkle_mountain_range_mmr_prover, generate_merkle_proof), which could be confused without careful reading. The descriptions do differentiate them by hash function (Poseidon vs SHA-256), structure (binary tree vs MMR), and use case, but the boundaries remain soft for an agent. The Groth16 verifier and EIP-712 hasher are clearly distinct.
Naming mixes conventions: some are long noun phrases (zero_knowledge_merkle_membership_proof, zk_snark_groth16_proof_verifier) while others begin with a verb (generate_merkle_proof) or are pure noun phrases (eip712_typed_data_hasher). There is no predictable verb_noun pattern, and 'proof'/'prover'/'verifier' suffixes are used inconsistently across similar tools.
Five tools is a reasonable, well-scoped set for a cryptography primitives server, with each primitive earning its place. It sits comfortably in the 3-15 range without feeling bloated.
The surface covers Merkle/MMR proof generation and a Groth16 verifier plus EIP-712 hashing, but there are notable gaps such as no Groth16/SNARK proof generation counterpart (only verification), no signature or key utilities, and no generic hashing helper. Agents needing to create SNARK proofs or sign typed data would hit dead ends.
