Md5 Calculator

What is Md5 Calculator?

Md5 Calculator is a Model Context Protocol (MCP) provider that calculates MD5 hashes from strings, JSON data, and base64‑encoded binary data. It is designed for use with MCP‑compatible clients such as Claude for Desktop.

How to use Md5 Calculator?

Install the package globally with npm install -g md5-mcp, then run the server with the command md5-mcp. For local installations use npx md5-mcp. Configure Md5 Calculator in your MCP client (e.g., Claude for Desktop) by adding an entry to mcpServers with the command md5-mcp or npx md5-mcp. Three tools are available: calculateMD5 (string input), calculateJSONMD5 (JSON data), and calculateBase64MD5 (base64‑encoded binary).

Key features of Md5 Calculator

• Calculate MD5 hashes from plain text strings
• Optional whitespace trimming before hashing
• Hash JSON data with control over formatting preservation
• Hash base64‑encoded binary data
• Easy integration with Claude and other MCP clients

Use cases of Md5 Calculator

• Verifying data integrity of strings or files
• Hashing JSON payloads for checksums or deduplication
• Converting base64‑encoded binary data (e.g., small files) into MD5 digests
• Automated hash generation inside AI‑assisted workflows

FAQ from Md5 Calculator

What input types does Md5 Calculator support?

Strings, JSON values (numbers, booleans, objects, arrays), and base64‑encoded binary data.

Does whitespace or formatting affect the resulting hash?

Yes. Every character is significant. Use the trimWhitespace option for strings or the preserveFormatting option for JSON to control the input before hashing.

Is MD5 cryptographically secure?

No. MD5 is no longer considered secure for cryptographic purposes. It is suitable only for data integrity checks, not for security‑critical applications.

How do I install Md5 Calculator?

Install globally via npm: npm install -g md5-mcp. Alternatively, clone the repository, run npm install and npm run build, then start with npm start. A programmatic API is also available for Node.js projects.

How do I configure Md5 Calculator with Claude for Desktop?

Add a mcpServers entry with the key md5-calculator and the command md5-mcp (if installed globally) or npx md5-mcp (if installed locally). See the README for the exact JSON configuration.
