mcp-bytesmith
A pure-Python Model Context Protocol server, built on the official MCP SDK (FastMCP), 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), 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, and random for
CSPRNG-backed bytes, tokens, and passphrases.
