Released on May 12, 2025, mcp-acronym-lookup is a lightweight Model Context Protocol (MCP) server designed to bridge the gap between specialized industry jargon and AI understanding. By allowing users to define their own acronym dictionaries via simple CSV files, it empowers AI agents to resolve abbreviations with precision and context.

Introducing mcp-acronym-lookup

At its core, mcp-acronym-lookup is a Go-based server that implements the MCP specification to provide AI agents with a dedicated tool for acronym resolution. Rather than relying on a hard-coded database or the general (and sometimes inaccurate) knowledge of a large language model, this server uses a user-provided CSV file as its source of truth.

The server introduces the lookupAcronym tool, which takes a target acronym and returns all matching definitions—including the full form and a detailed description—from the loaded CSV. To ensure reliability, the server automatically sanitizes inputs and handles case-insensitive lookups, making it robust against minor formatting differences. For deployment flexibility, it supports both the standard stdio transport and an optional SSE (Server-Sent Events) transport for HTTP-based access.

Why it Matters

Every professional field—from medicine and law to software engineering and aerospace—has its own unique set of initialisms. While modern AI models are impressive, they often struggle with niche terminology or may confuse a common acronym with a domain-specific one.

mcp-acronym-lookup solves this by putting the control back in the user’s hands. By maintaining a curated CSV list, organizations and individuals can ensure that their AI assistants are speaking the same language as their human counterparts. This eliminates ambiguity, reduces hallucinations, and ensures that technical documentation or internal communications are interpreted correctly every time.

Getting Started

Getting mcp-acronym-lookup up and running is straightforward. You can download pre-compiled binaries from the GitHub Releases page or install it directly using Go:

go install github.com/UnitVectorY-Labs/mcp-acronym-lookup@latest

To use the server, you only need to provide the path to your acronym CSV file via the ACRONYM_FILE environment variable:

export ACRONYM_FILE=/path/to/your/acronyms.csv
mcp-acronym-lookup

For those needing an HTTP-based service, the server can be started in SSE mode:

mcp-acronym-lookup --sse :8080

Whether you are managing a complex project with hundreds of internal codes or simply want to streamline your workflow, mcp-acronym-lookup provides a simple, effective way to enhance your AI’s vocabulary.
