Container Use vs Soma
A side-by-side look at the Container Use and Soma MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Container Use for code execution work; choose Soma for code execution as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Container Use when
- You need dedicated capabilities in the Code Execution domain.
- Its auth model fits you: No auth required.
Choose Soma when
- You need dedicated capabilities in the Code Execution domain.
- You prefer a local stdio subprocess transport.
- You want tools like
soma_verify_code, soma_generate_verified_code.

Soma tools 2
soma_verify_codeRun candidate code against tests inside an isolated sandbox and return a PASS/FAIL verdict with a signed, offline-checkable certificate (Ed25519). Use this to independently confirm that code actually works before trusting it. Two test shapes: - function mode (default): tests = [{"input": [arg1, arg2], "expected": value}] and provide 'entrypoint' (the function name). - stdio mode: set mode='stdio' and tests = [{"stdin": "...", "expected_stdout": "..."}]; no entrypoint needed. Supported languages include python, javascript, typescript, go, c, cpp, java, rust, ruby, php, bash and more.soma_generate_verified_codeAsk Soma to write code for a task. When the task is verifiable, the returned code has been executed against derived tests in an isolated sandbox before it is returned, and a certificate (verdict + tests passed) is attached. Include concrete examples in the prompt (e.g. doctest-style '>>> f(2) == 4') to make the result verifiable rather than best-effort.

Frequently asked questions
Container Use is categorized under Code Execution and uses an install path we have not confirmed yet. Soma belongs to Code Execution and uses a local stdio subprocess. Pick Container Use for code execution work and Soma for code execution.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client. Container Use has no confirmed install command yet — follow its own setup instructions.
Container Use is listed as free. Auth: no auth required. Soma has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add dagger-container-use and soma-2 as separate keys in the same mcpServers object, and your assistant will call tools from either one.
