get-alertstate

Implementation Reference

• src/seq-server.ts:205-226 (handler)

  The handler function for the 'get-alertstate' tool. It makes a request to the SEQ API endpoint '/api/alertstate' using the makeSeqRequest helper, formats the response as JSON text, and handles errors by returning an error message.

    async () => {
      try {
        const alertState = await makeSeqRequest<any>('/api/alertstate');
        
        return {
          content: [{
            type: "text",
            text: JSON.stringify(alertState, null, 2)
          }]
        };
      } catch (error) {
        const err = error as Error;
        return {
          content: [{
            type: "text",
            text: `Error fetching alert state: ${err.message}`
          }],
          isError: true
        };
      }
    }
  );

• src/seq-server.ts:202-226 (registration)

  Registers the 'get-alertstate' tool with the MCP server, including empty input schema and inline handler function.

  server.tool(
    "get-alertstate",
    {},
    async () => {
      try {
        const alertState = await makeSeqRequest<any>('/api/alertstate');
        
        return {
          content: [{
            type: "text",
            text: JSON.stringify(alertState, null, 2)
          }]
        };
      } catch (error) {
        const err = error as Error;
        return {
          content: [{
            type: "text",
            text: `Error fetching alert state: ${err.message}`
          }],
          isError: true
        };
      }
    }
  );

• src/seq-server.ts:204-204 (schema)

  Empty Zod schema object indicating the tool takes no input parameters.

  {},

• src/seq-server.ts:31-56 (helper)

  Helper function used by the handler to make authenticated HTTP requests to the SEQ API, constructing the URL with API key and parameters, handling fetch and JSON parsing with error checking.

  async function makeSeqRequest<T>(endpoint: string, params: Record<string, string> = {}): Promise<T> {
    const url = new URL(`${SEQ_BASE_URL}${endpoint}`);
    
    // Add API key as query parameter
    url.searchParams.append('apiKey', SEQ_API_KEY);
    
    // Add additional query parameters
    Object.entries(params).forEach(([key, value]) => {
      if (value !== undefined && value !== null) {
        url.searchParams.append(key, value);
      }
    });
  
    const headers: Record<string, string> = {
      'Accept': 'application/json',
      'X-Seq-ApiKey': SEQ_API_KEY
    };
  
    const response = await fetch(url.toString(), { headers });
  
    if (!response.ok) {
      throw new Error(`SEQ API error: ${response.statusText} (${response.status})`);
    }
  
    return response.json();
  }
