About mcp-acronym-lookup
mcp-acronym-lookup is a configuration-driven MCP server that turns a three-column CSV of abbreviations into a lookup tool. It returns all matching full forms and descriptions as JSON, with case-insensitive matching that ignores non-alphanumeric characters.
Key features
- 01Load acronym definitions from a CSV
- 02Return full forms and descriptions
- 03Match without regard to case
- 04Ignore non-alphanumeric input characters
- 05Run over stdio or Streamable HTTP
Use cases
- 01Resolve abbreviations in agent queries
- 02Look up definitions from a team CSV
- 03Return every definition for a duplicate key
MCP support
Exposes a single acronym lookup tool to MCP clients, returning matching definitions in JSON. It supports stdio by default and optional Streamable HTTP transport.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.
Details
From the project README
mcp-acronym-lookup
A lightweight, configuration-driven MCP server that ingests a CSV of acronyms and initialisms to expose a lookup tool for their full meanings and descriptions.
Purpose
mcp-acronym-lookup lets you turn any simple three‑column CSV file of abbreviations into an MCP server whose single tool can resolve those acronyms or initialisms, returning all matching definitions in JSON to your agent.
Releases
All official versions of mcp-acronym-lookup are published on GitHub Releases. Since this MCP server is written in Go, each release provides pre-compiled executables for macOS, Linux, and Windows—ready to download and run.
Alternatively, if you have Go installed, you can install mcp-acronym-lookup directly from source using the following command:
go install github.com/UnitVectorY-Labs/mcp-acronym-lookup@latest
Configuration
This server is configured using one environment variable and an optional command-line flag:
Environment Variables
ACRONYM_FILE: (required) Path to the CSV file containing the acronym definitions. The CSV must have three columns in order:acronym,full form, anddescription.
Command‑Line Flags
--http <addr>: Run in Streamable HTTP transport on the given address (for example,:8080). If omitted, the server runs in standard I/O mode (recommended by the MCP specification).
CSV Format
The CSV file should be UTF‑8 encoded and may include a header row. Example:
acronym,full form,description
LOL,Laugh Out Loud,Used in digital communication to indicate something is funny.
ASAP,As Soon As Possible,Commonly used to express urgency in completing a task or response.
DIY,Do It Yourself,Refers to the practice of creating or repairing things without professional help.
Run in Streamable HTTP Transport
To run as an MCP HTTP server, use the --http <addr> flag (e.g., --http :8080). If not specified, the server defaults to stdio.
The MCP server can then be accessed at the following endpoint: http://localhost:<port>/mcp
Limitations
- The server only supports one CSV file per instance.
- Matches are case‑insensitive and ignore non‑alphanumeric characters; input strings are sanitized before lookup.
- If multiple definitions exist for the same sanitized key, all definitions are returned in a list.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
