Can I use Perplexity AI as a CLI?

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

Can I expose Perplexity AI through MCP?

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

Where are Perplexity AI credentials stored?

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

Can I deny write access for Perplexity AI MCP tools?

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

Connect Perplexity AI to LangChain

Bridge LangChain agents to local KosmoKrator integration tools through MCP or headless CLI calls.

Use the MCP gateway when the agent should discover tools, or wrap kosmo integrations:call for fixed chains. The gateway is local, scoped to this integration, and starts with --write=deny so LangChain can inspect read-capable tools without receiving write access by default.

Perplexity AI MCP Config for LangChain

Keep the gateway scoped to the integration and operation class needed by the chain.
