use-find-mcp-by-id.ts

Overview

The use-find-mcp-by-id.ts file provides a custom React hook named useFindMcpById that enables efficient lookup of a specific MCP (MCP server) object by its unique identifier (id). It leverages another hook, useListMcpServer, to fetch the full list of MCP servers from the server or state, and then exposes a method to find one MCP server from this list by its id.

This hook is primarily used in React functional components where MCP server data is needed, and a lookup by ID is required without refetching the entire data set repeatedly.

Detailed Explanation

useFindMcpById Hook

export function useFindMcpById()

Purpose:

• Provides a function to find an MCP server from a cached or fetched list by its unique identifier.

Internal Implementation:

• Calls useListMcpServer() to obtain MCP server data. This hook presumably returns an object containing data, where data.mcp_servers is an array of MCP server objects.

• Defines a function findMcpById(id: string) that searches through data.mcp_servers to find the MCP server with the matching id.

Return Value:

An object containing:

• findMcpById(id: string): MCPServer | undefined

  A function that takes a string id and returns the MCP server object with that id, or undefined if not found.

Parameters:

• None directly; it internally uses the data from useListMcpServer.

Usage Example:

import React from 'react';
import { useFindMcpById } from './use-find-mcp-by-id';

function McpDetails({ mcpId }: { mcpId: string }) {
  const { findMcpById } = useFindMcpById();
  const mcp = findMcpById(mcpId);

  if (!mcp) {
    return <div>MCP Server not found</div>;
  }

  return (
    <div>
      <h2>{mcp.name}</h2>
      <p>ID: {mcp.id}</p>
      {/* Render other MCP properties */}
    </div>
  );
}

Important Implementation Details

• The hook depends on useListMcpServer to fetch or provide MCP server data. This means the availability and freshness of the data depend on that hook's implementation.

• The search is a simple linear search (Array.prototype.find) on the MCP server list, which is efficient for small to moderately sized arrays. If the list becomes very large, consider optimizing with a map or indexed structure.

• The hook returns a function rather than the MCP server directly, enabling flexible usage and lookups by dynamic IDs.

Interaction with Other Parts of the System

• useListMcpServer Hook: This file depends on useListMcpServer (imported from @/hooks/use-mcp-request), which is responsible for retrieving the list of MCP servers. The exact implementation is not included here, but it likely involves fetching data from an API or context.

• React Components: This hook is designed to be used inside React components to get MCP server details by ID, avoiding repeated fetching or data duplication.

• MCP Server Data Model: The MCP servers are expected to have at least an id property. Other properties are accessible depending on the MCP server’s shape.

Summary

• The file defines a simple utility hook to find an MCP server by its ID from an existing list.

• It relies on a separate hook to provide the MCP server list.

• It exposes a convenient search function to components.

• The implementation is straightforward, using array search.

• Suitable for React applications managing MCP server data with IDs.
