Sounio Compiler
Drive check, compile, run, and test for Sounio programs from your coding agent on the local machine.
Overview
Sounio Compiler is a MCP server for the Build phase that check, compile, run, and test Sounio programs locally through four stdio tools.
What is this MCP server?
- 4 MCP tools: sounio_compile, sounio_check, sounio_run, sounio_test
- Local-only server (localOnly: true) via PyPI package sounio-mcp-server
- Resources for stdlib modules (sounio://stdlib/{module}) and error codes (sounio://errors/{error_code})
- stdio transport v0.1.0 from the Sounio lang repo tools/mcp subfolder
- 4 publisher-listed tools: sounio_compile, sounio_check, sounio_run, sounio_test
- 2 resource URI patterns plus localOnly: true in registry metadata
Community signal: 2 GitHub stars.
What problem does it solve?
Agents cannot reliably validate Sounio code without local compiler feedback, so compile errors and test failures stall the edit loop.
Who is it for?
Builders hacking on Sounio who want the agent to own the compile-test cycle on a local dev machine.
Skip if: Teams not using Sounio, cloud-only CI-only workflows without local toolchain, or JavaScript-only front-end work.
What do I get? / Deliverables
After install, your agent can check, compile, run, and test Sounio sources and pull stdlib or error-code resources without leaving the MCP session.
- Agent-invoked compile, check, run, and test results for Sounio projects
- Read access to stdlib module and error-code MCP resources
- Tight local edit-compile-test loop without manual CLI context switching
Recommended MCP Servers
Journey fit
Language toolchain MCP belongs in Build when you implement and verify backend or systems code. Backend subphase covers compiler-adjacent servers that turn source into binaries and test results, not browser or payment integrations.
How it compares
Local language-compiler MCP with four tools, not a blockchain payment or browser automation server.
Common Questions / FAQ
Who is Sounio Compiler for?
Developers writing Sounio who want Claude Code, Cursor, or similar agents to compile, run, and test code on their machine.
When should I use Sounio Compiler?
Use it during Build backend work whenever the agent edits Sounio sources and needs immediate check, compile, run, or test feedback.
How do I add Sounio Compiler to my agent?
Install sounio-mcp-server from PyPI, ensure the Sounio toolchain is on the host, register the stdio MCP server, and note it is local-only per registry metadata.
