Can I use Signnow as a CLI?

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

Can I expose Signnow through MCP?

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

Where are Signnow credentials stored?

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

Can I deny write access for Signnow MCP tools?

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

Connect Signnow 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.

Signnow MCP Config for LangChain

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