5 #deterministic MCP Servers & Clients
Every MCP server and client below is tagged #deterministic — install one to give Claude, Cursor, VS Code, or any other MCP-compatible client access to deterministic tools.

Quantoracle
QuantOracledev
63 deterministic quant computation tools for autonomous financial agents. Options, derivatives, risk, portfolio, statistics, crypto/DeFi, macro/FX, TVM. 1,000 free calls/day — no signup.
Shikamaru: Day-Count and Accrued Interest Engine
JayOfemi
Provably correct day-count and accrued-interest calculations. A small, dependency-light TypeScript library and an MCP server, so an AI agent can get the exact number instead of guessing.
Euclid
euclidtools
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.
Archrad Deterministic Mcp
archradhq
stdio MCP server from @archrad/deterministic—same engine as the archrad CLI. Validates architecture IR (structural + IR-LINT), merges local PolicyPack YAML, checks export drift vs generated files on disk, and returns static archrad_suggest_fix guidance per built-in rule code. No
Taprun
LeonTing1010
Your AI agent scrapes X today, gets broken HTML tomorrow. Taprun compiles the site once into a deterministic program, then `tap doctor` monitors health contracts + structural diffs to catch silent breakage before your data goes stale. 140+ pre-built skills across 68+ sites. Works
Frequently asked questions
What is a #deterministic MCP server?
- An MCP server tagged #deterministic implements the Model Context Protocol so AI assistants like Claude, Cursor, and VS Code can access deterministic-related tools, data, or APIs.
How many #deterministic MCP servers and clients are there?
- mcp.so currently lists 5 MCP servers and clients tagged #deterministic.
How do I install a #deterministic MCP server?
- Open any server below and copy its install snippet into Claude Desktop, Cursor, VS Code, or another MCP client's configuration — remote servers need no separate download.
