Can I use Convex as a CLI?

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

Can I expose Convex through MCP?

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

Where are Convex credentials stored?

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

Can I deny write access for Convex MCP tools?

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

Connect Convex to Vercel AI SDK

Use KosmoKrator as a local integration gateway for Vercel AI SDK agents and scripts.

Create an MCP client that starts or connects to the KosmoKrator gateway for the selected integration. The gateway is local, scoped to this integration, and starts with --write=deny so Vercel AI SDK can inspect read-capable tools without receiving write access by default.

Convex MCP Config for Vercel AI SDK

Prefer CLI JSON calls when a workflow only needs one deterministic integration operation.

{
  "mcpServers": {
    "kosmokrator-convex": {
      "type": "stdio",
      "command": "kosmo",
      "args": [
        "mcp:serve",
        "--integration=convex",
        "--write=deny"
      ]
    }
  }
}

Run the Gateway Manually

kosmokrator mcp:serve --integration=convex --write=deny

Why Use KosmoKrator Here

Scoped tools

Expose only Convex 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.

Convex Tools Visible to Vercel AI SDK

Vercel AI SDK sees stable MCP tool names generated from the Convex integration catalog.

MCP tool	Source function	Type	Description
`integration__convex__convex_list_tables`	`convex.convex_list_tables`	Read	List all tables in the Convex deployment.
`integration__convex__convex_get_table`	`convex.convex_get_table`	Read	Get metadata and schema for a specific Convex table.
`integration__convex__convex_query_documents`	`convex.convex_query_documents`	Read	Query documents from a Convex table with optional filtering and pagination.
`integration__convex__convex_create_document`	`convex.convex_create_document`	Write	Create a new document in a Convex table.
`integration__convex__convex_update_document`	`convex.convex_update_document`	Write	Update an existing document in a Convex table.
`integration__convex__convex_delete_document`	`convex.convex_delete_document`	Write	Delete a document from a Convex table.
`integration__convex__convex_get_current_user`	`convex.convex_get_current_user`	Read	Get the authenticated Convex user's profile information. Returns account details like name and email. Use this to verify API connectivity.
