Implementation Reference

• index.js:50-64 (registration)

  Registration of the 'Generate-Session' MCP tool, including name, description, input schema {requestToken: z.string()}, and inline handler function.

  server.tool(
    "Generate-Session",
    "Generate a new session token using request token",
    { requestToken: z.string() },
    async ({ requestToken }) => {
      try {
        const response = await tokenManager.generateSession(requestToken);
        return {
          content: [{ type: "text", text: "Session generated successfully" }],
        };
      } catch (error) {
        return { content: [{ type: "text", text: `Error: ${error.message}` }] };
      }
    }
  );

• index.js:54-63 (handler)

  Inline handler for the Generate-Session tool that invokes tokenManager.generateSession(requestToken) and formats the MCP response.

  async ({ requestToken }) => {
    try {
      const response = await tokenManager.generateSession(requestToken);
      return {
        content: [{ type: "text", text: "Session generated successfully" }],
      };
    } catch (error) {
      return { content: [{ type: "text", text: `Error: ${error.message}` }] };
    }
  }

• tokenManager.js:50-61 (helper)

  TokenManager.generateSession method: core logic using KiteConnect to generate session token from requestToken and apiSecret, saves token to file, returns response.

  async generateSession(requestToken) {
    try {
      const response = await this.kc.generateSession(
        requestToken,
        this.apiSecret
      );
      await this.saveToken(response);
      return response;
    } catch (error) {
      throw new Error(`Error generating session: ${error.message}`);
    }
  }
