Perform advanced mathematical, statistical and symbolic computations. Solve equations, evaluate expressions and support scientific and engineering calculations.
OpenCode is an open-source agent for the terminal. Remote MCP servers go in its config file and sign in through OAuth.
This guide connects Scientific Calculator to OpenCode through MewCP, so OpenCode can use Scientific Calculator's 3 tools, like health_check, evaluate_expression and list_supported_operations.
Scientific Calculator needs no credentials, but every call still runs through MewCP: scoped, checked and logged like any other.

Other clients
Scientific Calculator works the same way in every client below. Pick yours for its own guide.
Free to start.
Scope access to the exact Scientific Calculator tools and accounts you allow, work and personal side by side. Anything outside that scope is refused at call time, even when the model asks for it.
Each call is logged: what ran, on which account, and whether it worked. Failures come back structured, so the agent knows whether to retry instead of guessing.
Every app sits behind one secure MCP URL, and there is no server for you to deploy or keep running. Add an integration in the dashboard and it is live on the next call, with no config to change and no new credentials to wire up. Tools load only when a task needs them, so your agent stays fast and focused however many apps you connect.
Edit ~/.config/opencode/opencode.json, or opencode.json in your project root.
Start a new chat and ask: "List the tools you can use from MewCP." You should see your connected apps.
Check server readiness and basic connectivity.
Evaluate a scientific calculator expression safely.
List supported operators, functions, and constants.
