Get spelling suggestions for a word
AI agents call get_suggestions to retrieve information from SpellChecker MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves spelling suggestions for a given word, which is fundamentally a read operation. It queries the spell-checker's knowledge base and returns results without creating, modifying, deleting, or executing any actions. The blast radius is minimal—misuse would only result in incorrect spelling suggestions returned to the user, with no impact on data integrity or system state.
