AssemblyAI docs MCP server
Hosted MCP server that lets coding agents search and fetch AssemblyAI documentation pages on demand while they write integration code.
Transport: Streamable HTTPAuth: No auth - BasetenStatus: GA
Baseten MCP server
Remote backend MCP server at api.baseten.co/mcp that wraps the Baseten REST API (deployments, autoscaling, logs, secrets, training jobs and more) so coding agents can deploy, debug and operate models in a Baseten workspace. It acts as the signed-in user with that account's permissions.
Transport: Streamable HTTPAuth: OAuth or API key - Deepgram
Deepgram CLI MCP server
The dg CLI (deepctl) includes a built-in MCP server that proxies tools from the Deepgram developer API so AI coding tools can call Deepgram speech-to-text, text-to-speech and voice agent APIs. Runs over stdio by default or SSE.
Transport: stdio, SSEAuth: API key - ElevenLabs
ElevenLabs hosted MCP server
Remote MCP server that lets AI assistants create, configure and manage ElevenAgents voice agents in a workspace (conversations, tests, tools, knowledge base, branches, triage tickets) and generate speech audio. Authentication is OAuth with scoped workspace permissions.
Transport: Streamable HTTPAuth: OAuth - ElevenLabs
ElevenLabs MCP server
Local Python MCP server for ElevenLabs Text to Speech and audio APIs (speech generation, voice cloning, transcription, audio processing), run with uvx and an ElevenLabs API key.
Transport: stdioAuth: API key - Hugging Face
Hugging Face MCP server
Hosted MCP server that connects assistants to the Hugging Face Hub to search and explore models, datasets, Spaces, papers and documentation, run Jobs and sandboxes, and call MCP-compatible Gradio Spaces as tools.
