# nginx config for food.tomflux.xyz
# Adds the MCP location to the existing web-app server block.
#
# The MCP connector is "authless" from claude.ai's side — the long secret in the
# URL path IS the credential. Only that exact prefix is proxied to the FastMCP
# service; everything else under /mcp/ falls through to the catch-all 301.
# Generate the secret once and keep it out of git, e.g.:
#     python -c "import secrets; print(secrets.token_urlsafe(32))"
# then replace REPLACE_WITH_LONG_SECRET below and in the claude.ai connector URL:
#     https://food.tomflux.xyz/mcp/REPLACE_WITH_LONG_SECRET/
