Today we’re excited to announce the initial public release of mcp-acronym-lookup (v0.1.0), a lightweight MCP server that brings instant acronym clarity to your AI workflows. Released on May 12, 2025, this tool solves a common pain point for teams working with domain-specific terminology: helping AI assistants quickly look up the meanings of acronyms and initialisms.

What’s New

As the first public release of mcp-acronym-lookup, version 0.1.0 introduces the complete foundational feature set:

Acronym Resolution at Your Fingertips

The core lookupAcronym tool enables AI assistants to instantly resolve acronyms to their full forms and descriptions. Whether your workflow involves technical documentation, regulatory compliance, or cross-domain collaboration, this tool ensures consistent terminology interpretation.

Smart Matching That Works for You

  • Case-insensitive lookup: Input “nasa”, “NASA”, or “NsA” – the results are the same
  • Multiple definition support: When an acronym has several meanings, all definitions are returned so your AI can provide context-aware responses
  • Sanitized input handling: Special characters are handled gracefully for cleaner matching

Flexible Deployment Options

Choose how mcp-acronym-lookup fits into your infrastructure:

  • Local stdio mode: Perfect for local development and testing
  • Remote SSE/HTTP mode: Deploy as a service with endpoints at /mcp/sse and /mcp/message

Production-Ready Distribution

Pre-built binaries are available for all major platforms out of the box:

  • Linux (AMD64, 386, ARM64)
  • Windows (AMD64, 386)
  • macOS (Intel AMD64 and Apple Silicon ARM64)

Each release includes checksums for integrity verification, giving you confidence in your deployments.

Why It Matters

AI assistants are only as helpful as the context they can access. Domain-specific acronyms – whether in healthcare, finance, engineering, or government – often create friction when AI systems misinterpret or miss them entirely. mcp-acronym-lookup closes that gap with a simple, maintainable approach:

Configuration-Driven by Design

Maintain your terminology dictionary as a standard CSV file. No databases, no complicated setup. Just add, edit, and reload your acronyms in the format you already know:

acronym,full form,description
NASA,National Aeronautics and Space Administration,The U.S. government agency...
LOL,Laugh Out Loud,Used in digital communication...

Integration Made Simple

Built on the Model Context Protocol (MCP) specification and powered by the mark3labs/mcp-go library, mcp-acronym-lookup integrates seamlessly with any MCP-compatible AI client or agent framework. The configuration is straightforward: set the ACRONYM_FILE environment variable and you’re running.

Enterprise-Grade Infrastructure

Even as a first release, this project ships with professional CI/CD pipelines including automated multi-platform builds, security scanning via CodeQL, and GitHub Actions security audits. When you adopt mcp-acronym-lookup, you’re building on a foundation designed for reliability and security from day one.

Getting Started

Since this is the initial release, setting up is fresh and straightforward:

  1. Download the pre-built binary for your platform from the v0.1.0 release page

  2. Prepare your CSV file with acronym definitions in the three-column format shown above

  3. Set the environment variable: 
    export ACRONYM_FILE=/path/to/your/acronyms.csv
  4. Run the server:
    • For local mode: ./mcp-acronym-lookup
    • For SSE mode: ./mcp-acronym-lookup --sse :8080
