It has no Prism component or history on Rime's status page, no published concurrency limit, alpha SDKs, English only, and no data-handling statement that covers caller audio.\n\n## Before you call either\n\n### ElevenLabs Agents API + MCP\n\n1. Create a key scoped to the agents endpoints with a credit limit before handing it to an agent\n2. Back off exponentially on `rate_limit_exceeded`, and wait for calls to finish on `concurrent_limit_exceeded`\n3. Use signed URLs or conversation tokens for private agents instead of exposing the API key\n4. Set `platform_settings.privacy.retention_days` where you don't need 2 years of history\n5. Pick a low-latency LLM, the pipeline waits on it every turn\n\n### Rime Prism\n\n1. Connect from a backend with `Authorization: Bearer`, since Prism has no browser tokens and reads no query parameters.\n2. Send `session.update` before any audio, or every append fails with `session_not_initialized`.\n3. Keep streaming audio, silence included, while Prism speaks, because it finds turn ends and interruptions from that audio.\n4. Ask for the continuation after each tool result, since Prism doesn't resume on its own, and never rerun a call with an unknown outcome.\n5. Pin the exact SDK version, because the SDKs are alpha and a new release can change the API.\n\n## Questions\n\n### Which is better for AI agents, ElevenLabs Agents API + MCP or Rime Prism?\n\nElevenLabs Agents API + MCP scores 71.4 (BB) on agent readiness against Rime Prism's 57.9 (C), and leads in 6 of 7 scored categories. Rime Prism leads on payments \u0026 pricing.\n\n### Do ElevenLabs Agents API + MCP and Rime Prism need an API key?\n\nElevenLabs Agents API + MCP takes an API key or an OAuth sign-in. Rime Prism needs an API key.\n\n### Can an agent call ElevenLabs Agents API + MCP and Rime Prism without installing anything?\n\nYes.
