Summary

• Add Daloopa as a third_party/ marketplace plugin, in the Attio (Add Attio third-party MCP plugin #339) / Hunter (Add Hunter third-party MCP plugin (API key header auth) #340) shape.
• One of nine hosted-MCP connectors that grok.com offers publicly (GrowthBook visibility all) and the Cursor marketplace does not. The server URL matches Grok's production connector_catalog.mcp_server_url.
• Registers the plugin in .cursor-plugin/marketplace.json and the root README table.
• Based on main; bottom of the stack now that feat(third_party): add Gamma plugin #347, feat(third_party): add Webull plugin #348, feat(third_party): add S&P Global plugin #349, feat(third_party): add Interactive Brokers plugin #350, feat(third_party): add Meltwater plugin #351 have merged.

Stack

Split from #345 into one PR per plugin. Independent plugins come first; the two with external prerequisites (Coinbase, BigQuery) are last so they never block the others.

Test plan

• node scripts/validate-plugins.mjs passes on this branch
• Endpoint probed for OAuth discoverability and dynamic client registration; the auth shape above is what the server actually supports
• README has Install / MCP / Before you connect / What agents can do / Notes / Docs / License, with capabilities sourced from vendor docs
• marketplace.json, plugin.json, and README table descriptions are identical
• Logo visually reviewed at 192×192
• Install from Cursor Settings → Plugins, complete sign-in, and smoke test discover_companies

Notes

• Endpoint verified against Grok's production connector_catalog.mcp_server_url.
• A separate docs server at docs.daloopa.com/mcp searches Daloopa's documentation and is not what this plugin connects to.
