fix(mcp): never 402 the MCP endpoint (0.6.3) - #94

Connector clients read a 402/403 with no WWW-Authenticate as 'needs sign-in', find no OAuth metadata, and fail. claude.ai's custom-connector submission hit 'Couldn't register with p0dcasters's sign-in service'. /api/mcp is now an open path; its throttle budget is unchanged.

claude.ai's connector submission failed with "Couldn't register with p0dcasters's sign-in service". The server is no-auth (
openmcp.jsonsaysauth: none), but the x402 crawl gateway answers/api/mcp402 for training UA tokens (anthropic-ai,ClaudeBot), bareChrome/strings with no Sec-Fetch-Mode, and so on. A connector client reads a non-2xx withoutWWW-Authenticateas needing sign-in, finds no OAuth metadata (all 404), and DCR fails./api/mcpadded to gatewayopenPaths(/.well-known/already was)🤖 Generated with Claude Code
