Grok plugin
CoreOfDiscovery for Grok
Record a prediction, grade it later against the original request, and see how calibrated you have been. The plugin already points at production. Sign in when Grok opens Connect.
1. Sign in
- Install the plugin or add the MCP URL below.
- Call a tool. Grok should open CoreOfDiscovery (Clerk) — sign in and Allow.
-
If Connect does not start, create a key at
Settings → API keys
(
mcp:tools,decisions:write,calibration:read) and setx-api-key.
2. Server
Grok Build reads this from the plugin. On Bot or grok.com Custom, paste it.
https://coreofdiscovery.vercel.app/api/mcp
OAuth first. Header x-api-key only if Connect never opens.
3. Install
Grok Build
grok plugin install coreofdiscovery --trust
Grok Bot — Settings → Plugins → custom MCP → URL
above. Complete Connect if prompted. In chat, type @ and attach the connector.
Grok chat — grok.com/connectors → New → Custom → same URL.
Then
Use /log-claim before a date, probability, or recommendation you cannot look up now.
/grade-claim scores the frozen ask. /how-did-i-do reads calibration.
If a tool returns unauthorized, use /connect.
