Can I use PostHog as a CLI?

Yes. KosmoKrator exposes a PostHog CLI through kosmo integrations:call and the provider shortcut command. Commands can return JSON for scripts, CI, and coding agents.

Can I expose PostHog through MCP?

Yes. The KosmoKrator MCP gateway can expose selected PostHog tools to clients such as Claude Code, Cursor, Codex, and other MCP-compatible tools.

Where are PostHog credentials stored?

PostHog credentials are configured in KosmoKrator's local integration settings and reused by CLI, Lua, and MCP gateway surfaces.

Can I deny write access for PostHog MCP tools?

Yes. Start the gateway with --write=deny for read-only clients, or use ask/allow only for trusted workspaces.

Connect PostHog to Codex

Use KosmoKrator as a local MCP proxy for Codex so coding sessions can reach selected integrations with explicit write policy.

Register kosmo mcp:serve as a local stdio server and choose the integration allowlist. The gateway is local, scoped to this integration, and starts with --write=deny so Codex can inspect read-capable tools without receiving write access by default.

PostHog MCP Config for Codex

Keep write access denied or ask-based unless the workspace is trusted.

Why Use KosmoKrator Here

Scoped tools

Expose only PostHog instead of a broad multi-service tool list.

Local credentials

Reuse credentials already configured for the KosmoKrator CLI and Lua runtime.

Write policy

Start read-only, then opt into ask or allow for trusted workspaces.
