use-find-mcp-by-id.ts

Overview

The use-find-mcp-by-id.ts file defines a custom React hook named useFindMcpById designed to facilitate the retrieval of a Management Control Point (MCP) server object by its unique identifier from a list of MCP servers fetched via another custom hook. This file abstracts the logic required to search for a specific MCP server from the MCP servers data store, providing a clean and reusable interface for components or other hooks that need to query MCP servers by ID.

Detailed Explanation

useFindMcpById

Description

useFindMcpById is a custom React hook that internally uses the useListMcpServer hook to obtain the list of MCP servers and returns a utility function findMcpById which allows searching for an MCP server by its id.

This encapsulation improves modularity and reusability, ensuring that the logic for fetching and searching MCP servers is maintained in a single place.

Usage

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

function ExampleComponent() {
  const { findMcpById } = useFindMcpById();

  const mcpId = "abc123";
  const mcpServer = findMcpById(mcpId);

  return (
    <div>
      {mcpServer ? (
        <p>MCP Server Name: {mcpServer.name}</p>
      ) : (
        <p>No MCP server found with ID: {mcpId}</p>
      )}
    </div>
  );
}

Parameters

• This hook does not accept any parameters.

Returns

An object containing the following property:

Implementation Details

• Dependency on useListMcpServer: The hook imports and uses useListMcpServer which is responsible for fetching or providing access to the full list of MCP servers. This separation of concerns allows useFindMcpById to focus solely on searching logic.

• Data Access Pattern: It destructures data from the useListMcpServer hook. The assumption is that data contains an object with a property mcp_servers which is an array of MCP server objects.

• Search Algorithm: The findMcpById function uses the native JavaScript Array.prototype.find method to locate the MCP server with the matching id. This is a linear search with O(n) time complexity, which is efficient for reasonably sized arrays.

Interaction with Other Parts of the System

• useListMcpServer Hook: This file depends on the useListMcpServer hook, which likely performs an API call or accesses a state/store to retrieve MCP server data. The design implies that the MCP server list is dynamic and may update over time, with useFindMcpById reflecting these updates reactively.

• Components or Other Hooks: Components or hooks that need to obtain an MCP server by ID will import and use useFindMcpById to access the findMcpById function. This promotes DRY principles and avoids duplication of search logic across the codebase.

Summary

• Purpose: Provides a reusable hook to find an MCP server by ID.

• Core Functionality: Uses MCP server data from useListMcpServer and exposes a search function.

• Usage Context: Intended for React components or hooks requiring MCP server lookup by ID.

• Efficiency: Simple linear search, appropriate for typical use cases.

• Extensibility: Can be extended with caching, memoization, or error handling if needed.
