Look up the definition of a word, including pronunciations, examples, and synonyms.
AI agents call dictionary_define to retrieve information from Mcp Everything without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward read-only query against a dictionary resource. It retrieves information without creating, modifying, deleting, or executing anything. The tool has negligible blast radius if misused by an AI agent, as the worst outcome would be requesting definitions for unusual or offensive words, which causes no harm.
From the tool's definition Tool name 'dictionary_define' and description state it 'Look up the definition of a word' — a pure retrieval operation with no side effects. Returns definitional data (pronunciations, examples, synonyms) only.

dictionary_define is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the dictionary_define rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for dictionary_define. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
