What is the Bloomy MCP server?

Connect Bloomy to Claude, Cursor or any other MCP client and it stops being a tab you switch to. An efficient and scalable bloom filter module built in pure python. The bloomy mcp server is what makes that connection.

What the server does

And imported/used as such ``` python from bloomy.bloom import *

Bloomy is a bloom filter module designed to be both lightweight and scalable. Bloomy does not use any external libraries, and scales internally to match scenarios. Bloomy also designed to reduce the rate of false positives. This is done my applying md5 hashing and bit rotation to generate k unique 8 byte hash values, and then using golden ratio compression for even distribution.

Installation

Installation goes through your MCP client rather than a global install: point it at bloomy on PyPI and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.

Where it fits

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. It is maintained by Sam Crochet; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against Bloomy's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Worth knowing first

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

It connects Bloomy to MCP-compatible AI assistants such as Claude and Cursor. Instead of copying data back and forth by hand, the assistant works with Bloomy directly.
