AI and ML platforms - official OpenRouter server
OpenRouter MCP server
Remote MCP server hosted by OpenRouter that lets coding assistants pull live model catalog, pricing, provider endpoint, benchmark, ranking and credit data, search the OpenRouter docs, and send billable test messages or image generations. OpenRouter hosts it at https://mcp.openrouter.ai/mcp with OAuth auth.

}Tools
send-message- Send a message to any model and get its reply, to test a prompt or compare models (billable).
generate-image- Generate an image from a text prompt and return it inline (billable).
list-models- Search the live model catalog with free-text search, sorting, and filters such as price, context, modality, provider and benchmarks.
get-model- Full details for one model by author/slug.
list-model-endpoints- Which providers serve a model, with price, latency, throughput, and data policy.
list-providers- List available providers for routing preferences.
list-daily-model-rankings- Which models are most used and trending by token volume.
list-app-rankings- Which apps drive the most OpenRouter traffic, filterable by category.
get-credits- Your remaining account credit.
get-generation- Cost, token counts, and serving provider for a specific generation id.
list-benchmarks- Third-party quality scores from Artificial Analysis and Design Arena.
list-task-classifications- Market share of OpenRouter traffic by task type with top models for each.
search-docs- Search the full OpenRouter docs.
send-feedback- Report a problem with one of your own generations to the OpenRouter team.
ping- Health check to verify the connection.

Notes and caveats
- Remote only.
- OAuth (PKCE with client registration) mints a dedicated OpenRouter API key labelled 'OpenRouter MCP: <app name>' with a 7-day expiry and a default $10 spend cap (editable on the consent screen); re-authenticate after expiry.
- Intended as a development assistant, not for running models in production apps.
- Not in Claude's connector directory, so Claude Desktop/Web users add it as a custom connector.
- Docs also document OpenCode config; the Cursor snippet is documented for ~/.cursor/mcp.json (Cursor CLI and IDE).
- Additional tools spawn-ori-eval and install-ori-harness are also listed.
- The separate @openrouter/mcp npm package is an MCP client helper for the Agent SDK, not this server.

- AssemblyAI
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.
Transport: Streamable HTTP, stdioAuth: OAuth or API key
