Overview

AI-generated overview

Arithym is a remote MCP math engine that gives an assistant exact, computed arithmetic results instead of model-generated numbers.

What you can do
  • Provides exact mathematical computation for AI agents, described as a precision math engine.
  • Offers a large set of exact methods (203 according to the provider) that an assistant can call for numeric work.
  • Aims to remove arithmetic hallucination by returning computed results rather than model guesses.
  • Tool-level details are not published in the listing, so the exact operations available are not documented here.
When to use it
Useful when an assistant needs reliable numeric answers — calculations, exact arithmetic, or math-heavy tasks — and you want results computed by a dedicated engine rather than produced by the language model.
Requirements
A remote MCP endpoint at arithym.xyz over streamable HTTP; no local package or runtime is needed. OAuth authentication is required, so the user must sign in with the provider's account flow. No environment variables or headers are declared.
Before you install
OAuth sign-in grants the server access tied to your account; review the scopes requested during authorization. The listing publishes no tool list, so what the assistant can invoke, and whether any calls are billed, cannot be verified from the provided information.

Installation

In SourceWeft

  1. Open Arithym in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/xyz.arithym%2Farithym/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
