Implementation Reference
- src/dhlab_mcp/server.py:222-239 (handler)The handler function for the 'lookup_word_lemma' tool. It is decorated with @mcp.tool(), which registers it as an MCP tool. The function uses dhlab.WordLemma to fetch the lemma of the input word and returns it as JSON.
@mcp.tool() def lookup_word_lemma(word: str) -> str: """Look up the lemma (base form) of a Norwegian word. Args: word: The word to look up Returns: JSON string containing lemma information """ try: word_lemma = dhlab.WordLemma(word) if hasattr(word_lemma, 'lemmas') and word_lemma.lemmas is not None: return word_lemma.lemmas.to_json(orient='records', force_ascii=False) return f"No lemma found for word: {word}" except Exception as e: return f"Error looking up word lemma: {str(e)}" - src/dhlab_mcp/server.py:222-222 (registration)The @mcp.tool() decorator registers the lookup_word_lemma function as an MCP tool.
@mcp.tool() - src/dhlab_mcp/server.py:224-230 (schema)The docstring provides the tool description, input argument 'word: str', and output format as JSON string, serving as the schema.
