Implementation Reference
- Handler function for the get-source-languages tool. It delegates to getDeeplLanguages('source') to retrieve available source languages from the DeepL API.
async function getSourceLanguages() { return await getDeeplLanguages('source'); } - workshops/deepl-simple-js/deepl-simple.js:40-44 (registration)Registration of the get-source-languages tool on the MCP server, specifying name, description, and handler function.
server.tool( 'get-source-languages', 'Get list of available source languages for translation', getSourceLanguages ); - Core helper function that calls the appropriate DeepL API method to get source or target languages, formats the response as MCP text content, and handles errors.
async function getDeeplLanguages(sourceOrDestination) { const method = sourceOrDestination == 'source' ? 'getSourceLanguages' : 'getTargetLanguages'; try { const languages = await deeplClient[method](); return mcpTextContentify(languages.map(JSON.stringify)); } catch (error) { return handleError(error); } } - Utility function to wrap strings or array of strings into the MCP expected content object structure with type 'text'.
function mcpTextContentify(param) { if (typeof(param) != 'string' && !Array.isArray(param)) { throw new Error('mcpTextContentify() expects a string or an array of strings'); } const strings = typeof(param) == 'string' ? [param] : param; const contentObjects = strings.map( str => ({ type: "text", text: str }) ); return { content: contentObjects }; }
