feat(ci): hit the prod MCP; drop the local posthog MCP server entirely - #3057
Merged
Conversation
The local MCP was a protocol proxy to the same us.posthog.com APIs the prod server fronts, but pinned to posthog master — so CI broke whenever master did (this week: a hard Redis dependency, before that the cold monorepo install). Delete the posthog clone/build/cache and the :8787 lifecycle; export MCP_URL=https://mcp.posthog.com/mcp so the wizard pairs local context-mill skills with the hosted MCP every real user hits. Requires wizard main with PostHog/wizard#975 (MCP_URL wins under --local-mcp). Generated-By: PostHog Code Task-Id: 2d43c175-646e-4d73-a974-760280c8c95b

Removes the posthog-master MCP server from wizard-ci and points the wizard at prod mcp.posthog.com instead.
The local server was a protocol proxy to the same us.posthog.com APIs (same phx key), but built from posthog master per run — so CI inherited master's breakages: this week's hard Redis dependency (services/mcp hono exits without redis:6379, from PostHog/posthog#72223), last cycle's 113-project cold install compiling node-rdkafka. Deleting the dependency removes both incident classes structurally: no posthog clone, no filtered pnpm install, no Redis, no :8787 readiness gate. context-mill stays local — it is the content under test. CI now exercises exactly the MCP every real user hits.
Depends on PostHog/wizard#975 (MCP_URL override wins under --local-mcp) being on the wizard ref under test — merge that first. Supersedes #3056 (the Redis stopgap): land that only if this needs to wait.
