Why Scavio Wins
- One hosted MCP endpoint serves both Hermes and OpenClaw agents. Instead of maintaining separate search tool integrations for each framework, teams configure mcp.scavio.dev/mcp once and both agent types gain five-platform search.
- Five-platform coverage enhances agent research quality for both frameworks. Hermes agents can cross-reference Google results with Reddit discussions; OpenClaw agents can combine YouTube content with marketplace data. Same tool, both frameworks.
- At $0.005/credit, multi-agent architectures using both Hermes and OpenClaw get consistent pricing regardless of which framework makes the search call. No per-framework pricing or separate accounts needed.
- Structured JSON with consistent schemas across all platforms simplifies agent tool responses for both frameworks. The same response parsing logic works in Hermes tool handlers and OpenClaw action definitions.
