UK Data: Code utilities
Deterministic string, list and number routines: palindromes, sorting, searching, validation, merging
What it does
UK Data: Code utilities is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.
No capability identified yet from its description.
Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence). None of this is a test of the tool.

32 tools offered to AI assistants
is_valid_ip_address· Validates whether a string is a properly formatted IPv4 address with four octets (0-255) separated by dots. (cost: 1 credit)find_max_subarray_sum· Finds the maximum sum of any contiguous subarray using Kadane's algorithm. (cost: 1 credit)merge_dictionaries· Merges two dictionaries into a single dictionary, with values from the second dictionary overwriting those from the first for duplicate keys. (cost: 1 credit)find_kth_smallest· Finds the kth smallest number in an unsorted list (1-indexed, where k=1 returns the smallest element). (cost: 1 credit)count_bits· Counts the number of set bits (1's) in the binary representation of a non-negative integer. (cost: 1 credit)binary_search· Performs binary search on a sorted list to find the index of a target value, returning -1 if not found. (cost: 1 credit)reverse_string· Reverses the order of characters in a given string, returning the string backwards. (cost: 1 credit)min_meeting_rooms· Finds the minimum number of meeting rooms required to accommodate all meetings given their time intervals. Uses interval scheduling algorithm. (cost: 1 credit)find_next_greater_element· For each element in a list, finds the next greater element to its right. Returns -1 if no greater element exists. (cost: 1 credit)binary_addition· Adds two binary numbers represented as strings and returns the sum as a binary string. Performs binary arithmetic with carry propagation. (cost: 1 credit)is_palindrome· Checks if a string is a valid palindrome, considering only alphanumeric characters and ignoring case and spaces. (cost: 1 credit)sort_numbers· Sorts a list of numbers in ascending order using a deterministic sorting algorithm. (cost: 1 credit)

find_pairs_with_sum· Finds all unique pairs of integers in a list that sum to a specified target value. Returns pairs as arrays. (cost: 1 credit)is_perfect_square· Checks if a number is a perfect square (i.e., the square of an integer). (cost: 1 credit)find_n_largest· Finds the n largest numbers from a list and returns them in descending order. (cost: 1 credit)is_valid_parentheses· Checks if a string contains properly balanced and nested parentheses, brackets, and braces. Returns true if every opening symbol has a matching closing symbol in the correct order. (cost: 1 credit)find_minimum_rotated_sorted_array· Finds the minimum element in a rotated sorted array using binary search. The array was originally sorted in ascending order then rotated at some pivot point. (cost: 1 credit)flatten_list· Flattens a nested list structure into a single-level list by recursively extracting all elements regardless of nesting depth. (cost: 1 credit)is_anagram· Checks if two words are anagrams by comparing if they contain the same characters with the same frequencies, ignoring case and whitespace. (cost: 1 credit)find_first_non_repeating_char· Finds the first character in a string that appears only once. Returns null if all characters repeat. (cost: 1 credit)find_equilibrium_index· Finds the equilibrium index in an array where the sum of elements to the left equals the sum of elements to the right. Returns -1 if no such index exists. (cost: 1 credit)find_missing_number· Finds the missing number in a sequence of integers from 0 to n where exactly one number is missing. Uses sum formula or XOR method. (cost: 1 credit)is_power· Checks if a given number is an exact integer power of a specified base. Returns true if num = base^k for some non-negative integer k, false otherwise. (cost: 1 credit)find_longest_word· Finds and returns the longest word in a given text string. If multiple words have the same maximum length, returns the first occurrence. (cost: 1 credit)can_attend_meetings· Determines if a person can attend all meetings given a list of time intervals by checking for overlapping time slots. Returns true if no meetings conflict, false otherwise. (cost: 1 credit)is_rotation· Checks if one string is a rotation of another string by verifying if str1 appears in str2 concatenated with itself. Returns true if str1 is a rotation of str2, false otherwise. (cost: 1 credit)find_peak_element· Finds a peak element in a list where an element is greater than its neighbors. Returns the index of any peak element found. (cost: 1 credit)find_duplicate_number· Finds the duplicate number in a list of integers where exactly one number appears more than once. Returns the duplicate value. (cost: 1 credit)is_sum_of_cubes· Checks if a number equals the sum of the cubes of its digits (e.g., 153 = 1³ + 5³ + 3³). Returns true if the condition holds, false otherwise. (cost: 1 credit)validate_sudoku· Checks if a 9x9 Sudoku board is valid by verifying that each row, column, and 3x3 sub-grid contains no duplicate digits 1-9. Returns true if valid, false otherwise. (cost: 1 credit)find_majority_element· Finds the majority element in a list that appears more than ⌊n/2⌋ times using Boyer-Moore voting algorithm. Returns the majority element if it exists, null otherwise. (cost: 1 credit)merge_sorted_lists· Merges two sorted lists into a single sorted list maintaining ascending order. Returns the merged sorted list. (cost: 1 credit)
What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method
Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
