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.
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
This server is configured using one environment variable and an optional command-line flag:
ACRONYM_FILE
: (required) Path to the CSV file containing the acronym definitions. The CSV must have three columns in order: acronym
, full form
, and description
.--sse <addr>
: Run in SSE (HTTP/SSE) mode on the given address (for example, :8080
). If omitted, the server runs in standard I/O mode.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.
By default the server runs in stdio mode, but if you want to run in SSE mode, you can specify the --sse
command line flag specifying the server name and port (ex: localhost:8080). This will run with the following endpoints that your MCP client can connect to:
