Implementation Reference
- src/index.js:237-270 (handler)The core handler function that receives Prometheus exposition format data and POSTs it to the VictoriaMetrics /api/v1/import/prometheus endpoint as text/plain, returning success or error response.async function vmPrometheusWrite(data) { let urlStr = VM_URL if (urlStr === "") { urlStr = VM_INSERT_URL } const url = new URL(urlStr + "/api/v1/import/prometheus"); const response = await fetch(url.toString(), { method: 'POST', headers: { 'Content-Type': 'text/plain' }, body: data }); const status = response.status; if (status === 204) { return { content: [{ type: "text", text: response.text(), }], isError: false }; } else { return { content: [{ type: "text", text: response.text(), }], isError: true }; } }
- src/index.js:40-53 (schema)Tool schema definition including name, description, and inputSchema requiring a 'data' string in Prometheus format.const VM_PROMETHEUS_WRITE_TOOL = { name: "vm_prometheus_write", description: "mport Prometheus exposition format data into VictoriaMetrics", inputSchema: { type: "object", properties: { data: { type: "string", description: "Metrics data in Prometheus exposition format", }, }, required: ["data"], } };
- src/index.js:127-134 (registration)Registration of the tool in the VM_TOOLS array, which is returned by the ListTools handler.const VM_TOOLS = [ VM_DATA_WRITE_TOOL, VM_QUERY_RANGE_TOOL, VM_QUERY_TOOL, VM_LABELS_TOOL, VM_LABEL_VALUES_TOOL, VM_PROMETHEUS_WRITE_TOOL ];
- src/index.js:363-366 (registration)Dispatch case in the CallToolRequestSchema handler that extracts arguments and calls the vmPrometheusWrite handler.case "vm_prometheus_write": { const {data} = request.params.arguments; return await vmPrometheusWrite(data); }
