How Unicode compares

Against every graded MCP server, from our own scans and uptime checks. Updated after each scan run.

Safety score: 85/100; higher than 70% of 48,255 servers
Tools: 3; the typical server has 7
Tools that change things: 0%; typical: 0%. Fewer write tools means less an agent can break

What its tools let an agent do: 3 read

Install Unicode in Claude Code, Cursor or VS Code

Runs npx -y unicode-mcp on your machine. Read the scan report first; the gateway never runs local packages.

claude mcp add unicode-mcp -- npx -y unicode-mcp

Add to Cursor

What the publisher says

From the Unicode repository's README, as published. We do not edit it. Read it on GitHub

unicode-mcp

A practical Unicode reference for agents working with internationalization, text processing, emoji, fonts, and character bugs.

Tools

get_character: inspect official UnicodeData fields for a code point.
search_blocks: search Unicode block names and ranges.
search_emoji: search the official emoji test data by name or annotation.

The server reads official Unicode data files and caches them only for the current process. Unicode normalization, rendering, grapheme segmentation, and font support are separate concerns and are not inferred by this server.

Run

npm install
npm run build
node dist/index.js
