GenPark Aho-Corasick Multi-Pattern Matcher

A local MCP server that runs an Aho-Corasick automaton to match many keywords at once against text, for dictionary matching and prompt content filtering.

What you can do

Match a dictionary of keywords against supplied text in a single pass using an Aho-Corasick automaton, reporting which patterns occur and where. Apply the same matching for content filtering in LLM prompts. Run entirely in memory with deterministic, low-latency results. Use it as a Python module or start it as a local MCP server process.

When to use it

Useful when an assistant needs to check text against a large keyword or blocklist quickly, such as filtering prompts, scanning content, or detecting many terms in one pass, and you prefer a self-contained local tool with no external dependencies.

Requirements

Runs as a local process on the user's machine (desktop only) and requires a Python runtime; the README states it uses only the Python standard library with no external pip dependencies. No authentication, environment variables or headers are declared.
