关于 Euclid MCP Server

AI models do not calculate. They predict the most probable next token. When the token is a number, it is often close, and sometimes wrong. The error compounds downstream.

概览

What is Euclid?

Euclid is a hosted MCP server that gives AI agents access to deterministic computation engines for arithmetic, conversions, statistics, datetime, encoding, finance, color, regex, validation, and geographic calculations. It replaces LLM prediction with guaranteed, correct results.

How to use Euclid?

Connect any MCP client that supports HTTP transport to https://mcp.euclidtools.com. Authentication is handled automatically via OAuth 2.1, and your client will prompt you to sign in on first connection. Pre-built instruction files (CLAUDE.md, AGENTS.md, .cursorrules, .windsurfrules) can be copied into your project to instruct the AI to use Euclid’s tools instead of guessing.

Key features of Euclid

  • 10 deterministic computation tools (calculate, convert, statistics, datetime, encode, finance, color, regex, validate, geo)
  • Near-zero latency: evaluates expressions in single-digit milliseconds
  • No sandbox or interpreter overhead required
  • Clear error messages with hints and examples on failure
  • Expression strings are minimal, reducing token cost versus code generation

Use cases of Euclid

  • Replace LLM arithmetic guessing with guaranteed correct mathematical computation
  • Perform unit conversions, date arithmetic, and financial formulas during conversation
  • Run statistical tests, encode/hash data, and validate structured inputs like emails or credit cards
  • Compute geographic distances, bearings, and polygon area for location-aware agents
  • Enforce deterministic computation everywhere — code, analytics, business metrics, and projections

常见问题

1

Why not just use code execution for math?

Code execution spins up a sandbox or interpreter with hundreds of milliseconds of latency, writes verbose code, and risks syntax errors. Euclid evaluates a single expression string in single-digit milliseconds with clear error messages and lower token cost.

2

How do I enforce that the AI uses Euclid’s tools?

Copy the appropriate rule file from the `rules/` directory into your project root or append it to your existing AI instruction file. The instruction tells the model to never guess numerical results and lists exactly which tool to use for each task.

3

What authentication does Euclid use?

Euclid uses OAuth 2.1. On first connection, your MCP client will prompt you to sign in automatically.

4

Which MCP clients are supported?

Any client that supports HTTP transport, including Claude Code, Claude Desktop, Cursor, Windsurf, and VS Code Copilot.

5

What are Euclid’s 10 tools?

calculate, convert, statistics, datetime, encode, finance, color, regex, validate, and geo. Each tool accepts structured arguments and returns deterministic results.
