Connect Dgraph 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.

Dgraph MCP Config for Vercel AI SDK

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

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

Run the Gateway Manually

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

Why Use KosmoKrator Here

Scoped tools

Expose only Dgraph 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.

integration__dgraph__dgraph_list_types dgraph.dgraph_list_types Read List all types defined in the Dgraph GraphQL schema. Returns type names for all user-defined and system types available in the database.
integration__dgraph__dgraph_list_indexes dgraph.dgraph_list_indexes Read List all indexes defined in the Dgraph schema. Returns types with their fields and directives, allowing you to identify indexed fields and their index types (hash, exact, term, fulltext, trigram, etc.).
integration__dgraph__dgraph_get_node dgraph.dgraph_get_node Read Get a specific node from Dgraph by providing its type and ID. Returns the node data including all populated fields. Use the type name as defined in your GraphQL schema.
integration__dgraph__dgraph_mutate dgraph.dgraph_mutate Write Execute a GraphQL mutation to add or update data in Dgraph. Provide the full GraphQL mutation string and optional variables. Supports all mutation operations including add, update, and upsert.
integration__dgraph__dgraph_drop_mutation dgraph.dgraph_drop_mutation Write Execute a GraphQL drop/delete mutation to remove data from Dgraph. Provide the full GraphQL mutation string for deleting nodes and optional variables. Use with caution as this permanently removes data.
integration__dgraph__dgraph_query dgraph.dgraph_query action Execute a custom GraphQL query against Dgraph. Provide the full GraphQL query string and optional variables. Supports all query operations including filtering, pagination, sorting, and nested traversals.
