Perform bidirectional search in the Mi\
AI agents call search_dictionary to retrieve information from Mi'kmaq Dictionary 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 dictionary data and search results without modifying, executing external operations, or causing destructive side effects. It is a pure read operation that queries linguistic reference material. The blast radius of misuse is minimal—an AI agent could at worst perform excessive searches causing DoS or waste resources, but no data is created, modified, or deleted.
From the tool's definition Tool name 'search_dictionary' combined with server description stating 'bidirectional lookup' and sibling tools like 'lookup_english_word', 'lookup_mikmaq_word', 'get_dictionary_stats', 'get_random_word' all indicate query/retrieval operations.
