OpenClaw Agent Instruction Registry
Connects Claude to AgentBase, an open registry of agent instruction files including system prompts, skills, workflows, and safety filters. Exposes four tools: search_registry for keyword and domain queries, get_file for pulling specific instructions by ID, list_categories for browsing available domains, and get_featured for top-rated content. Useful when you want agents to dynamically load domain-specific instructions at runtime instead of hardcoding prompts, or when teams need to share and version control system prompts across multiple agent deployments. The registry itself is CC0 licensed and browsable at agentbase-registry.vercel.app. Install via npx with the @agentbase1/mcp-server package.
