io.github.daedalus/mcp-hashlib is a MCP server that exposes Python hashlib hashing to your agent over stdio.
About
io.github.daedalus/mcp-hashlib is a lightweight Model Context Protocol server that exposes Python hashlib operations to AI coding agents such as Claude Code, Cursor, and Codex. developers shipping APIs, CLIs, or automation often need repeatable digests for caching keys, webhook signatures, content-addressed storage, or test fixtures; this server centralizes those calls behind MCP tools instead of scattering inline crypto code. It runs over stdio and installs from PyPI as `mcp-hashlib`, which keeps setup familiar for Python-first indies. The catalog treats it as a phase-specific integration and backend subphase: you wire it when implementation needs hashing, not when you are still validating market fit. Pair it with your agent’s normal edit-and-test loop; it does not replace security review for password storage policies or HMAC key management.
- Stdio MCP server (PyPI `mcp-hashlib`) wrapping Python’s standard `hashlib` module
- Agent-callable hashing without embedding crypto snippets in every chat thread
- Version 0.1.2 published on PyPI with GitHub source at daedalus/mcp-hashlib
- Fits local agent workflows that need deterministic digests for tests and scripts
- MCP integration, not a standalone CLI skill—register once, reuse across projects

What it does
Let your coding agent compute and verify cryptographic hashes (MD5, SHA-256, etc.) through MCP instead of hand-rolling hashlib calls or shell one-offs.
Who is it for?
Best when you're building Python-backed products and want agents to compute or verify hashes during implementation and testing.
Skip if: Skip if you need a managed secrets vault, HSM-backed signing, or non-Python runtimes without an MCP bridge.
What you get
Your agent can request standard library hashes through MCP with one configured server, keeping backend and test code consistent.
- Registered stdio MCP server exposing hashlib-backed tools
- Agent-accessible digest operations for backend and test workflows
- Repeatable hashing calls without duplicating crypto boilerplate

FAQ
Who is io.github.daedalus/mcp-hashlib for?
and small-team developers using MCP-enabled agents who implement APIs, scripts, or backends in Python and want hashlib available as tools.
When should I use io.github.daedalus/mcp-hashlib?
During Build when you need digests for caches, integrity checks, test data, or signature prep—after you know what you are shipping.
How do I add io.github.daedalus/mcp-hashlib to my agent?
Install the PyPI package `mcp-hashlib` (v0.1.2), add a stdio MCP server entry pointing at that package, and restart Claude Code, Cursor, or your MCP client.
