Tisane Labs for AI agents

Tisane Labs offers natural language processing for content analysis, including language detection, entity comparison, and translation, used by teams building text-heavy features. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.
