  • twelvelabs_add_kb_textAdd Text Document to Knowledge Base

    Add a plain text document to the ElevenLabs knowledge base. After adding, attach it to an agent by updating the agent's knowledge_base config with the returned document ID. Args: - name: Display name for the document - text: The full text content to store Returns: The new document's ID and name. Note: This creates the document in your account-level knowledge base but does NOT automatically attach it to any agent. Use twelvelabs_get_agent to check an agent's current KB attachments.

  • twelvelabs_add_kb_urlAdd URL to Knowledge Base

    Add a web page to the knowledge base by URL. ElevenLabs will crawl the URL and extract the text content. Args: - name: Display name for the document - url: The URL to crawl Returns: The new document's ID. Note: This creates the document in your account-level knowledge base but does NOT automatically attach it to any agent. Use twelvelabs_get_agent to check an agent's current KB attachments.

  • twelvelabs_get_agentGet Agent Configread-only

    Get the FULL configuration of an ElevenLabs agent, including fields the official ElevenLabs MCP connector does not expose: - Complete system prompt text - LLM model (e.g., gpt-4.1-nano, claude-3-5-haiku) - Temperature setting - All knowledge base document references - Voice ID and TTS settings (stability, similarity_boost) - Language configuration - Webhook URL (if configured) - First message Args: - agent_id: The agent's ID string (get from twelvelabs_list_agents) Returns: Full agent configuration as formatted text.

  • twelvelabs_get_agent_promptGet Agent System Prompt (Full)read-only

    Get the complete, untruncated system prompt for an ElevenLabs agent. Use this when you need to read, review, or edit the full prompt text. twelvelabs_get_agent truncates the prompt to 500 chars for readability — this tool returns the entire thing. Args: - agent_id: The agent ID

    Get the complete transcript and post-call analysis for a conversation. Returns two things: 1. The full turn-by-turn transcript (what the agent and user actually said) 2. The analysis: data_collection fields (scores, email, role, recommendation) and evaluation_criteria results (booleans like interview_completed) This is your primary tool for debugging: if scores are wrong, feedback is missing, or the interview ended incorrectly, read the transcript here first. Args: - conversation_id: The conversation ID (from twelvelabs_list_conversations) Returns: Formatted transcript + structured an…

  • twelvelabs_get_kb_docGet Knowledge Base Documentread-only

  • twelvelabs_list_agentsList Agentsread-only

    List all Conversational AI agents in your ElevenLabs account. Returns each agent's ID, name, and creation timestamp. Use this to find agent IDs before calling twelvelabs_get_agent for full details. Returns: Array of { agent_id, name, created_at_unix_secs }

  • twelvelabs_update_agent_conversation_capabilitiesUpdate Agent Conversation Capabilitiescan change or delete data

    ⚠️ This modifies a LIVE agent's configuration. Confirm with the user before calling.

    ⚠️ This modifies a LIVE agent's configuration. Confirm with the user before calling. Replace the system prompt and/or first message for an ElevenLabs agent.
