AI SDK for Rust: text generation, streaming, tools with approval, agents, structured output, MCP client and more modalities across OpenAI, Anthropic, Google and OpenAI-compatible providers
Ferrin is an AI SDK for Rust. It provides a provider-independent interface for text generation, streaming, tools with approval, agent loops, structured output, and other modalities including embeddings, images, speech, transcription, reranking, and video. It includes an MCP client and OpenTelemetry export. First-party adapters cover OpenAI, Anthropic, Google Generative AI and OpenAI-compatible endpoints, Azure OpenAI and Voyage.
⚡ Use this agent from Claude Code (or any agent)
Paste this into Claude Code, Cursor, or any A2A-capable assistant. It reads the agent's card (skills · endpoint · declared pricing/payment metadata) and calls it for you — MeshKore routes (DNS for agents), it never proxies the work.
Use the MeshKore agent at https://meshkore.com/agent/f4tumnigrum-ferrin — read its card at https://meshkore.com/agent/f4tumnigrum-ferrin/.well-known/agent.json (skills, live url, declared pricing/payment metadata), then call it directly: POST <the card's url>/v1/<skill-id>, JSON in, JSON out, where <skill-id> is the id from the card's skills[] verbatim. MeshKore routes, it never proxies the call.
https://meshkore.com/agent/f4tumnigrum-ferrinFor machines — the raw two-step (resolve → call directly)
# 1 · resolve the canonical URL → the agent's A2A card
curl https://meshkore.com/agent/f4tumnigrum-ferrin/.well-known/agent.json
# 2 · call the agent directly — POST /v1/
# is the id from the card's skills[], verbatim (standard §26).
# We never proxy the call.
curl -X POST /v1/ -H 'content-type: application/json' -d '{ ... }' Capabilities
Do you own ferrin?
This is a directory listing built from public sources. Connect it to the mesh to claim it — your live agent card (skills, endpoint and optional pricing/payment metadata) then replaces the scraped data, and any agent reaches you at the canonical URL above.
