feat(mcp): add 34 official vendor-hosted remote MCP servers to the catalog
Competitor-parity expansion (Perplexity Computer, Manus, Claude, ChatGPT
connector catalogs) limited to endpoints a generic MCP client can actually
use. Every entry was live-probed: initialize handshake for no-auth servers,
RFC 9728 protected-resource metadata -> AS metadata with a
registration_endpoint for OAuth servers (true DCR only).
No-auth (7): deepwiki, context7, microsoft-learn, exa, aws-knowledge,
wolfram, telnyx*
API key (3): github (PAT bearer - GitHub reserves browser OAuth for
pre-registered IDEs), perplexity, telnyx
OAuth 2.1 + DCR (24): canva, zapier, monday, clickup, todoist, dropbox,
wix, miro, calendly, ramp, plaid, fireflies, neon, prisma-postgres,
postman, globalping, buildkite, semgrep, attio, close, apify, cloudinary,
parallel-search, twelve-data, indeed
Deliberately excluded after probing OAUTH_NO_DCR (vendor requires a
pre-registered app; generic clients cannot connect): Box, Slack, HubSpot,
Zoom, PagerDuty, Brex, Docusign, Stack Overflow, Google Workspace.
