Implementation Reference

• src/index.ts:256-276 (handler)

  Handler function for the 'searchMeetingsWithSpeechText' tool. Invokes the private _callKokkaiApi helper with the 'meeting' endpoint, handles errors by returning formatted text, and returns the API response as pretty-printed JSON text.
  async (params) => { const result = await this._callKokkaiApi("meeting", params); if (result.error) { return { content: [ { type: "text", text: `Error fetching meetings with speech text: ${result.message} ${result.details || ""}`, }, ], }; } return { content: [ { type: "text", text: JSON.stringify(result, null, 2), }, ], }; }
• src/index.ts:244-255 (schema)

  Tool-specific input schema for 'searchMeetingsWithSpeechText', extending the common Kokkai search parameters with a maximumRecords field limited to 1-10.
  { ...kokkaiCommonSearchParams, maximumRecords: z .number() .int() .min(1) .max(10) .optional() .describe( "Maximum number of records to retrieve (1-10) for meetings with speech text. Default is 3." ), },
• src/index.ts:241-277 (registration)

  MCP server tool registration for 'searchMeetingsWithSpeechText', including name, description, input schema, and inline handler function.
  this.server.tool( "searchMeetingsWithSpeechText", "Searches for meetings and includes the full text of ALL speeches within those meetings from the Kokkai API (会議単位出力). Returns meeting info and all speech texts. Max 10 records.", { ...kokkaiCommonSearchParams, maximumRecords: z .number() .int() .min(1) .max(10) .optional() .describe( "Maximum number of records to retrieve (1-10) for meetings with speech text. Default is 3." ), }, async (params) => { const result = await this._callKokkaiApi("meeting", params); if (result.error) { return { content: [ { type: "text", text: `Error fetching meetings with speech text: ${result.message} ${result.details || ""}`, }, ], }; } return { content: [ { type: "text", text: JSON.stringify(result, null, 2), }, ], }; } );
• src/index.ts:146-197 (helper)

  Core private helper method used by the tool handler to construct query parameters, make HTTP requests to the Kokkai API, parse JSON responses, and handle both API and network errors uniformly.
  private async _callKokkaiApi( endpoint: string, params: Record<string, any> ): Promise<any> { const queryParams = new URLSearchParams(); for (const key in params) { if (params[key] !== undefined && params[key] !== null) { queryParams.append(key, String(params[key])); } } queryParams.append("recordPacking", "json"); // Always request JSON const url = `${KOKKAI_API_BASE_URL}/${endpoint}?${queryParams.toString()}`; console.log(`Calling Kokkai API: ${url}`); try { const response = await fetch(url, { headers: { "User-Agent": "MCP Agent Kokkai Client/1.0", }, }); const responseData = (await response.json()) as any; if (!response.ok) { const errorMessage = responseData.message || "Unknown API error"; const errorDetails = responseData.details ? responseData.details.join("; ") : ""; console.error( `Kokkai API Error: ${errorMessage} ${errorDetails}`, responseData ); return { error: true, status: response.status, message: errorMessage, details: errorDetails, rawResponse: responseData, }; } return responseData; } catch (error: any) { console.error("Network or parsing error calling Kokkai API:", error); return { error: true, message: error.message || "Failed to fetch or parse API response.", }; } }
• src/index.ts:6-134 (schema)

  Shared Zod schema definitions for common Kokkai API search parameters, spread into the tool's input schema.
