define

Pack: merriam-webster · Connect: https://pipeworx.io/mcp (see Connect below for a single-pack URL)

No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/define for the schema, then POST the same URL with its arguments for the data.

Look up a word in the Merriam-Webster dictionary — the authoritative American English dictionary. Returns word definitions (short definitions), part of speech (noun, verb, adjective, etc.), pronunciation, and etymology (word origin). When the word is not found, returns close spelling suggestions instead. Example: define({ word: “ephemeral” })

Parameters
