My EchoKit could hear. It could think. Today, it finally talked back. 🎙️ Day 17 of the First 30 Days with EchoKit: Wiring ElevenLabs as the text to voice provider. @elevenlabsio ⚠️ One tiny step almost broke everything: if you pick a voice, you must add it to “My Voices” — or

Yesterday MCP was donated to the Agentic AI Foundation. Day 15 of The First 30 Days with EchoKit, let's add actions for EchoKit with MCP. With just two lines in config.toml, EchoKit can call MCP tools like web search — fully driven by your voice. Voice → LLM → MCP tools →

Love seeing open agentic protocols find a permanent home. MCP joins the Agentic AI Foundation, and EchoKit already speaks it (SSE + HTTP stream). Tutorial coming soon.
Anthropic is donating the Model Context Protocol to the Agentic AI Foundation, a directed fund under the Linux Foundation. In one year, MCP has become a foundational protocol for agentic AI. Joining AAIF ensures MCP remains open and community-driven.

@echokit_dev is like the LEGO of voice AI agents — you can build any kind of AI companion you want!
Now EchoKit speaks Italian! This device opens infinite opportunities for makers, and the integration with LLMs is so natural that it's becoming my favorite AI companion.

Cloudflare is down again, but EchoKit can keep going. Since everything can be runs locally — ASR, LLM, TTS — your voice AI stays online using open-source models on your own device. Check out @juntao 's article from @freeCodeCamp on how to build a voice AI agent using
