mcp-crypto-tools
Cryptography and encoding tools for AI agents, served via the Model Context Protocol (MCP).
Tools
hash
Hash text using MD5, SHA-1, SHA-256, SHA-512, or HMAC. Compare two hash values. Compute all algorithms at once.
Actions: hash, hmac, compare, hash_all
encode_decode
Encode and decode text using Base64, URL encoding, HTML entities, hex, or binary. Auto-detect encoding format.
Actions: base64_encode, base64_decode, url_encode, url_decode, html_encode, html_decode, hex_encode, hex_decode, binary_encode, binary_decode, detect
generate_id
Generate unique identifiers: UUID v4, nanoid, ULID, CUID, or random strings with configurable length and charset.
Types: uuid, nanoid, ulid, cuid, random
password
Generate secure passwords with configurable character sets, length, and count. Check password strength with entropy calculation and crack time estimation.
Actions: generate, check_strength
jwt
Decode JWT tokens to inspect header and payload, check expiry status, or create unsigned JWTs for testing.
Actions: decode, check_expiry, create_unsigned
