This feature will be reintroduced once proper environment isolation is supported in the product. ### API #### TLS Our TLS endpoints no longer allow some older and insecure cipher modes. Most clients should not be affected as they already negotiate a modern cipher mode. ## New Endpoints ### Agents Platform #### MCP Tool Configuration - [POST /v1/convai/mcp-servers/{mcp_server_id}/tool-configs](/docs/api-reference/mcp/tool-configuration/create) - Create configuration overrides for a specific MCP tool. - [GET /v1/convai/mcp-servers/{mcp_server_id}/tool-configs/{tool_name}](/docs/api-reference/mcp/tool-configuration/get) - Retrieve configuration overrides for a specific MCP tool. - [PATCH /v1/convai/mcp-servers/{mcp_server_id}/tool-configs/{tool_name}](/docs/api-reference/mcp/tool-configuration/update) - Update configuration overrides for a specific MCP tool. - [DELETE /v1/convai/mcp-servers/{mcp_server_id}/tool-configs/{tool_name}](/docs/api-reference/mcp/tool-configuration/delete) - Remove configuration overrides for a specific MCP tool. ### Text to Dialogue - [POST /v1/text-to-dialogue/with-timestamps](/docs/api-reference/text-to-dialogue/convert-with-timestamps) - Generate dialogue with character-level alignment and voice segment information. - [POST /v1/text-to-dialogue/stream/with-timestamps](/docs/api-reference/text-to-dialogue/stream-with-timestamps) - Stream dialogue generation with character-level alignment and voice segment information. ### Tokens - [POST /v1/single-use-token/{token_type}](/docs/api-reference/tokens/create) - Generate time-limited single-use tokens for secure operations. ### Music API - [POST /v1/music/stem-separation](/docs/api-reference/music/separate-stems) - Separate audio into individual stems (vocals, drums, bass, instruments).
