Sumo data MCP
Five tools cover rankings, bouts, rikishi search, profiles, and basho listings. Configure https://osada.us/mcp in an MCP client. This is a Streamable HTTP endpoint, not a browser page.
AI Search MCP
The search tool supports natural-language searches of articles and profiles. Configure https://ask.osada.us/mcp in an MCP client. Browser GET requests are not supported.
Agent Skills and WebMCP
See the published skill descriptions for data and URL guidance. Supported browsers separately register four WebMCP tools when the site opens.
