# Dictionary Api — how to use (mcp.ai)

Connect your Dictionary Api account and use 1 tools for education straight from your AI agent. Connect with your own API key. The Merriam-Webster Dictionary API provides developers with access to comprehensive dictionary and thesaurus content, including definitions, etymologies, audio pronunciations, synonyms, and antonyms.
