Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@mcp-hashlib compute SHA256 hash of 'hello world'"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
An MCP server that exposes hashlib functionality to LLMs.
mcp-name: io.github.daedalus/mcp-hashlib
pip install mcp-hashlibRelated MCP server: mcp-hash
from mcp_hashlib import mcp, mainThe MCP server exposes the following hashlib functions:
hash_md5 - MD5 hash

hash_sha256 - SHA256 hash
hash_sha512 - SHA512 hash
hash_sha224 - SHA224 hash
hash_sha384 - SHA384 hash
hash_sha3_224 - SHA3-224 hash
hash_sha3_256 - SHA3-256 hash
hash_sha3_384 - SHA3-384 hash
hash_sha3_512 - SHA3-512 hash
hash_blake2b - BLAKE2b hash (512-bit)
hash_blake2s - BLAKE2s hash (256-bit)
hash_shake_128 - SHAKE-128 XOF hash
hash_shake_256 - SHAKE-256 XOF hash
hash_pbkdf2_hmac - PBKDF2-HMAC key derivation
hash_scrypt - Scrypt key derivation
hash_file_digest - Hash file-like object
hash_new - Create hash with any available algorithm
hash_info - Get algorithm info
hash_update - Incremental hashing
hash_copy - Copy hash object
hash_properties - Get algorithm properties

Scored across 22 tools
Each tool has a clearly distinct purpose: specific hash algorithms, incremental update, file digest, key derivation, and general factory. No overlapping functionality.
All tools follow a consistent 'hash_' prefix and snake_case naming, with algorithm names lowercase and verbs for operations. Perfectly uniform.
22 tools cover a broad range of hashing operations without being excessive; each tool serves a necessary function in the domain.
Includes major hash algorithms, key derivation functions, file hashing, incremental updates, and utility tools. No obvious gaps for a general-purpose hashing server.
500+ deterministic tools for AI agents: math, conversion, validation, hashing, encoding, date/time.
Exact hashing, base64/hex/URL encoding, JWT decoding and UUIDs for AI agents. No auth required.
Utility tools for AI agents: hashing, text stats, validation, DNS, currency, GEO audits.
