Implementation Reference
- src/tools/upstream.ts:6-13 (handler)Executes the create_upstream tool by calling the Admin API with POST to /upstreams if no id, or PUT to /upstreams/{id} if id provided.server.tool("create_upstream", "Create an upstream service with load balancing settings", CreateUpstreamSchema.shape, async (args) => { const upstreamId = args.id; if (!upstreamId) { return await makeAdminAPIRequest(`/upstreams`, "POST", args.upstream); } else { return await makeAdminAPIRequest(`/upstreams/${upstreamId}`, "PUT", args.upstream); } });
- src/schemas/upstream.ts:70-70 (schema)Zod schema for validating input to the create_upstream tool, consisting of optional id and upstream configuration object.export const CreateUpstreamSchema = z.object({ id: z.string().optional().describe("upstream id"), upstream: UpstreamSchema });
- src/tools/upstream.ts:6-13 (registration)Registers the create_upstream tool on the MCP server with description, input schema, and handler function.server.tool("create_upstream", "Create an upstream service with load balancing settings", CreateUpstreamSchema.shape, async (args) => { const upstreamId = args.id; if (!upstreamId) { return await makeAdminAPIRequest(`/upstreams`, "POST", args.upstream); } else { return await makeAdminAPIRequest(`/upstreams/${upstreamId}`, "PUT", args.upstream); } });
- src/utils/adminAPI.ts:11-80 (helper)Helper function that performs HTTP requests to the APISIX Admin API endpoint, handling success and error responses as MCP CallToolResult. Used by the create_upstream handler.export async function makeAdminAPIRequest( path: string, method: string = "GET", data?: object ): Promise<CallToolResult> { const baseUrl = `${APISIX_SERVER_HOST}:${APISIX_ADMIN_API_PORT}${APISIX_ADMIN_API_PREFIX}`; const url = `${baseUrl}${path}`; try { const response = await axios({ method, url, data, headers: { "X-API-KEY": APISIX_ADMIN_KEY, "Content-Type": "application/json", }, }); return { content: [ { type: "text", text: JSON.stringify(response.data, null, 2), }, ], }; } catch (error) { if (axios.isAxiosError(error)) { console.error(`Request failed: ${method} ${url}`); console.error( `Status: ${error.response?.status}, Error: ${error.message}` ); if (error.response?.data) { try { const stringifiedData = JSON.stringify(error.response.data); console.error(`Response data: ${stringifiedData}`); } catch { console.error(`Response data: [Cannot parse as JSON]`); } } return { isError: true, content: [ { type: "text", text: JSON.stringify( `Status: ${error.response?.status}\nMessage: ${error.message} Data:\n${JSON.stringify(error.response?.data || {}, null, 2)}`, null, 2 ), }, ], }; } else { return { isError: true, content: [ { type: "text", text: JSON.stringify(error, null, 2), }, ], }; } } }
