microsandbox-mcp (superradcompany/microsandbox-mcp) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: there is no public source to read and no endpoint we can reach, so there is nothing for us to inspect. No publisher has claimed this listing.

// key findings
✅
69 tools verified — handlers match their declared behaviour
29 read-only tools verified — handlers contain no write/delete/exec
✅
No credential exfiltration, no sensitive file access, no obfuscation
Static analysis found nothing flowing your secrets to unexpected places.
✅
Open source with a license and README
Anyone can audit the code, the license is declared, and the publisher documents what it does.
// environment variables
To run this server yourself, you supply these values. They go in your own MCP client configuration and stay on your machine. The secret label means the value is sensitive, not that the server mishandles it.
configMICROSANDBOX_MCP_DEFAULT_TIMEOUT_MS120000 Default timeout budget for exec-style operations
configMICROSANDBOX_MCP_ENABLE_DANGEROUS0 Enables future dangerous operations; destructive cache operations still require explicit confirm: true
configMICROSANDBOX_MCP_HOST_PATHScurrent working directory Colon-separated allowlist for bind mounts, host copy, snapshot save/load, and other host path operations
configMICROSANDBOX_MCP_HOST_PATH_POLICYallowlist Set to unrestricted to allow any host path
configMICROSANDBOX_MCP_MAX_OUTPUT_BYTES1048576 Default cap for command output, logs, and file reads
configMICROSANDBOX_MCP_SESSION_TTL_MS900000 Idle TTL for in-memory exec sessions
configMSB_LIBKRUNFW_PATHunset Optional path to libkrunfw
configMSB_PATHunset Optional path to the msb binary for SDK/runtime discovery
// quality suggestions

All four hints declared on every tool

69/69 tools missing one or more hints — sandbox_exec (missing: openWorldHint); sandbox_shell (missing: openWorldHint); sandbox_exec_start (missing: openWorldHint), +66 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Tool inputs are validated

60/69 tool handlers declare input schemas (87%)

Declare an inputSchema with zod/joi/yup on every tool definition.

Tests exist

No test files found

Add tests that exercise each declared tool.

Shell command execution

1 child_process call — runs shell commands

Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.

Claim the listing to review these findings one by one and send us a correction where you disagree, straight to the team. Claiming also means we tell you when the grade moves, and reach you first if we find anything urgent.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 4 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
