Limits and privacy

Each source IP can make up to 120 requests per minute. AISub keeps only daily totals of tool calls by tool and client type; it does not store IP addresses, query arguments or responses. See the privacy policy.

Prices are for reference. Whether you can buy a plan and the final amount are confirmed at the provider's checkout.

Publishing to the MCP Registry

This repository holds the server.json listed in the official MCP Registry. The server code runs on AISub and is not part of this repository.

Maintainers publish with mcp-publisher, using DNS authentication for yuanwu.ai:

  1. Generate an Ed25519 key pair and add the TXT record v=MCPv1; k=ed25519; p=<public key> at the apex of yuanwu.ai. See the registry's authentication guide. Keep the private key out of this repository.
  2. Bump version in server.json and run mcp-publisher validate.
  3. Run mcp-publisher login dns --domain yuanwu.ai --private-key <private key>, then mcp-publisher publish.
