Implementation Reference

src/index.ts:183-205 (handler)

The handler function for the 'get-block-content' tool. It constructs a URL by appending the 'type' query parameter to the endpoint, fetches the data using apiClient.get, and returns the response content formatted as MCP text content.

async ({ endpoint, type }) => {
    try {
        const url = endpoint + "?type=" + type;
        const response = await apiClient.get(url);

        if (response.status !== 200) {
            throw new Error(`Failed to fetch block data: ${response.status}`);
        }

        return {
            content: [
                {
                    type: "text",
                    text: JSON.stringify(response.data, null, 2),
                }
            ],
        };
    }
    catch (error) {
        console.error("Error fetching block data:", error);
        throw new Error("Failed to fetch block data");
    }
}

src/index.ts:181-181 (schema)
Input schema defining required parameters 'endpoint' (string) and 'type' (string) using Zod.
```
inputSchema: { endpoint: z.string(), type: z.string() }
```

src/index.ts:176-206 (registration)

Registers the 'get-block-content' tool with the MCP server, providing name, metadata (title, description, inputSchema), and the handler function.

server.registerTool(
    "get-block-content",
    {
        title: "Get Block Data",
        description: "Fetch the content of a block from a given URL. Use this tool to retrieve the code block content from the authenticated URL.",
        inputSchema: { endpoint: z.string(), type: z.string() }
    },
    async ({ endpoint, type }) => {
        try {
            const url = endpoint + "?type=" + type;
            const response = await apiClient.get(url);

            if (response.status !== 200) {
                throw new Error(`Failed to fetch block data: ${response.status}`);
            }

            return {
                content: [
                    {
                        type: "text",
                        text: JSON.stringify(response.data, null, 2),
                    }
                ],
            };
        }
        catch (error) {
            console.error("Error fetching block data:", error);
            throw new Error("Failed to fetch block data");
        }
    }
);

src/utils/http-client.ts:60-66 (helper)

Definition of the apiClient used in the handler. It provides HTTP methods including 'get' which performs authenticated fetch requests to the FlyonUI API base URL.

export const apiClient: HttpClient = {
    get: createMethod("GET"),
    post: createMethod("POST"),
    put: createMethod("PUT"),
    delete: createMethod("DELETE"),
    patch: createMethod("PATCH"),
};
