By GitHub stars, harness-sdk has more community adoption, but the best choice depends on your specific use case.

stellar-raven: Stellar Raven is a remote MCP server built on Cloudflare Workers, offering `search` and `execute` tools to agents. It provides a unified catalog of Stellar ecosystem services and skills, enabling agents to discover and execute capabilities securely within a sandboxed environment.; harness-sdk: This monorepo holds the Strands Agents SDKs for Python and TypeScript plus Strands harness, a fully assembled agent created with one create_harness() call. It runs in your own process and covers the agent loop, tools, MCP, multi-agent patterns, memory, sessions, guardrails, tracing and evals across Bedrock, Anthropic, OpenAI, Gemini and other providers.
