mcp-bytesmith
A pure-Python Model Context Protocol server, built on the official MCP SDK (MCPServer), exposing a toolbox of byte-wrangling utilities — encoding, hashing, number crunching, and Ethereum primitives — all computed locally and for real, with no network calls or remote APIs.

Tools
mcp-bytesmith ships an always-on core toolset built entirely on the Python
standard library, so it works out of the box with no extra dependencies. This
covers the everyday primitives: encode and decode move data between a wide
set of schemes (hex, the Base64/Base32 family, Base58/Base58check, Base45, and
more), hash computes cryptographic, CRC, and fast non-cryptographic digests,
hash_file checksums a file on disk and soft-verifies it against an expected
digest, hmac computes and verifies keyed-hash authentication tags, and
num_convert translates integers between bases. Rounding out the core are
bytes_edit (pad/trim/slice/concat byte glue), data_uri (build and parse
data: URIs), otpauth_uri (build and parse otpauth:// authenticator
provisioning URIs), unicode_normalize and charset_transcode for text and
character-set work, string_escape/string_unescape for JSON/JS/Python/C
escaping, codepoints for per-scalar Unicode inspection, random for
CSPRNG-backed bytes, tokens, and passphrases, and id_generate for UUIDs
(v1/v4/v5/v7), ULIDs, and nanoids. password_hash turns a password
into a verifiable storage string and checks one back — scrypt and PBKDF2 out of
the box, bcrypt and the argon2 variants with the crypto extra — while
derive_key derives raw key bytes from a password or secret via PBKDF2, scrypt,
or HKDF.
