Implementation Reference

  • The inline handler function for the 'list-container-registry-auths' tool. It performs a GET request to the '/repository/auths' endpoint using novitaRequest and returns the result as formatted JSON text content.
    server.tool("list-container-registry-auths", {}, async () => {
        const result = await novitaRequest("/repository/auths", "GET");
        return {
            content: [
                {
                    type: "text",
                    text: JSON.stringify(result, null, 2),
                },
            ],
        };
    });
  • src/tools.ts:442-452 (registration)
    Registration of the 'list-container-registry-auths' tool on the MCP server, with empty input schema and the handler inline.
    server.tool("list-container-registry-auths", {}, async () => {
        const result = await novitaRequest("/repository/auths", "GET");
        return {
            content: [
                {
                    type: "text",
                    text: JSON.stringify(result, null, 2),
                },
            ],
        };
    });
  • Helper function that registers all container registry auth related tools, including 'list-container-registry-auths'.
    function registerRegistryAuthTools(server: McpServer) {
        server.tool("list-container-registry-auths", {}, async () => {
            const result = await novitaRequest("/repository/auths", "GET");
            return {
                content: [
                    {
                        type: "text",
                        text: JSON.stringify(result, null, 2),
                    },
                ],
            };
        });
    
        server.tool("create-container-registry-auth", {
            name: z
                .string()
                .nonempty()
                .max(255)
                .describe("Name for the container registry auth."),
            username: z
                .string()
                .nonempty()
                .max(511)
                .describe("Registry username."),
            password: z
                .string()
                .nonempty()
                .max(1024)
                .describe("Registry password."),
        }, async (params) => {
            const result = await novitaRequest("/repository/auth/save", "POST", params);
            return {
                content: [
                    {
                        type: "text",
                        text: JSON.stringify(result, null, 2),
                    },
                ],
            };
        });
    
        // Delete Container Registry Auth
        server.tool("delete-container-registry-auth", {
            id: z
                .string()
                .nonempty()
                .describe("ID of the container registry auth to delete. Please ensure it exists before deleting. Before calling the MCP tool, please show me the name to help identify it. You can use the `list-container-registry-auths` tool to check the ID if needed."),
        }, async (params) => {
            const result = await novitaRequest(`/repository/auth/delete`, "POST", {
                id: params.id,
            });
            return {
                content: [
                    {
                        type: "text",
                        text: JSON.stringify(result, null, 2),
                    },
                ],
            };
        });
    }
  • src/tools.ts:7-14 (registration)
    Main registration function that calls registerRegistryAuthTools(server), which registers the 'list-container-registry-auths' tool.
    export function registerAllTools(server: McpServer) {
        registerClusterTools(server);
        registerProductTools(server);
        registerGPUInstanceTools(server);
        registerNetworkStorageTools(server);
        registerRegistryAuthTools(server);
        registerTemplateTools(server);
    }
Behavior1/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Tool has no description.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness1/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Tool has no description.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Tool has no description.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Tool has no description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose1/5

Does the description clearly state what the tool does and how it differs from similar tools?

Tool has no description.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines1/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Tool has no description.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
