# Sudhanva API authentication

The sudhanva.me API and MCP server require no API key, OAuth grant, bearer
token, cookie, client certificate, or account. They expose only public,
read-only portfolio and publication data.

Clients must not send secrets or private data. Use canonical HTTPS URLs,
respect cache and rate-limit headers, and parse structured errors before
retrying. Cross-origin JSON reads are allowed; the MCP server validates browser
Origin headers and is primarily intended for server-to-server agent clients.
