At a Glance & Executive Verdict
Waxseal Sdk
Cryptography · Local stdio
Quality: 53/100 (Good) | Auth: other
Hash
Cryptography · Local stdio
Quality: 47/100 (Fair) | Auth: No auth required
Verdict Summary: Choose Waxseal Sdk if you need specialized Cryptography tools running via a local process. Choose Hash if your workspace requires Cryptography integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Waxseal Sdk when:
You need dedicated capabilities in the Cryptography domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: other (Free / Open Source).
You have access to required keys: WAXSEAL_PRIVATE_KEY_PEM.
Primary tools included: Verify on-chain identities by fingerprint, Validate Ed25519 document signatures, Check human approval tokens.
On-chain Ed25519 identity for AI agents — verify seals by fingerprint, validate document signatures, and gate irreversible actions behind human-signed approval tokens. Hosted at api.waxseal.id/mcp; local install (npx @waxseal/mcp) for signing.
Compute a cryptographic hash (hex digest) of text: algorithm = md5, sha1, sha256 (default), sha384, or sha512. Keyless/offline; the input is not stored or transmitted. MD5/SHA-1 are legacy (checksums only, not security).
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Waxseal Sdk is categorized under Cryptography and uses a local stdio subprocess. In contrast, Hash belongs to Cryptography using local stdio subprocess. Select Waxseal Sdk when you need capabilities focused on cryptography and Hash when you require tools for cryptography.
