Implementation Reference

• index.ts:328-345 (handler)

  Handler for the 'find_apis' tool. It extracts the requirement and optional context from arguments, constructs a search query for Perplexity API, calls the /search endpoint, and returns the response as text content.

  case "find_apis": {
    const { requirement, context = "" } = request.params
      .arguments as {
      requirement: string;
      context?: string;
    };
    const response = await this.axiosInstance.post('/search', {
      query: `API for ${requirement} ${context}`
    });
    return {
      content: [
        {
          type: "text",
          text: JSON.stringify(response.data, null, 2),
        },
      ],
    };
  }

• index.ts:164-184 (registration)

  Tool registration entry for 'find_apis' in the listTools response, including name, description, and input schema definition.

  {
    name: "find_apis",
    description:
      "Find and evaluate APIs that could be integrated into a project",
    inputSchema: {
      type: "object",
      properties: {
        requirement: {
          type: "string",
          description:
            "The functionality or requirement you're looking to fulfill",
        },
        context: {
          type: "string",
          description:
            "Additional context about the project or specific needs",
        },
      },
      required: ["requirement"],
    },
  },

• index.ts:168-183 (schema)

  Input schema for the 'find_apis' tool defining the expected arguments: requirement (required string) and optional context string.

  inputSchema: {
    type: "object",
    properties: {
      requirement: {
        type: "string",
        description:
          "The functionality or requirement you're looking to fulfill",
      },
      context: {
        type: "string",
        description:
          "Additional context about the project or specific needs",
      },
    },
