## MCP tools (1)

### `tenki_auth_status` (~86 tokens)

Report whether the server has a usable Tenki credential, which kind (API key vs OAuth session token), and the endpoint it targets — verified with a live identity probe. Call this first when other tools fail with auth errors, or when this is the only tool available (which means no credential is configured). Reports status only; it does not log in and never returns the token.

Output parameters:

- `authenticated` (boolean): True only when a credential is present AND a live identity probe succeeded.
- `credential` (string): Kind of credential the server is running with. Never includes the token itself.
- `detail` (string): Human-readable status plus, when unauthenticated, how to supply a credential.
- `endpoint` (string): Control-plane base URL the server is pointed at.
- `error` (string): Why the probe failed, when a credential is present but unusable (expired, revoked, wrong endpoint).
- `identity` (object): Identity returned by the live probe, when it succeeded.
- `source` (string): Environment variable the credential came from (TENKI_AUTH_TOKEN takes precedence over TENKI_API_KEY).
- `toolsRegistered` (integer): How many tools this server registered. Without a credential only this one is registered.

## Common questions

### What is the Tenki Sandbox MCP server?

Tenki Sandbox MCP is listed in the public MCP registry as io.github.LuxorLabs/tenki-mcp. Disposable microVM sandboxes for AI agents: run code, read/write files, git, preview URLs. This page covers its npm package (@tenkicloud/mcp).

### Is the Tenki Sandbox MCP server safe to use?

Tenki Sandbox MCP scores 97 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 20 September 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Tenki Sandbox MCP server expose?

Tenki Sandbox MCP exposes 1 tool: tenki_auth_status. Their descriptions and schemas cost roughly 86 tokens of context every time the server is loaded.

### Is the Tenki Sandbox MCP server still maintained?

Tenki Sandbox MCP is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Tenki Sandbox MCP server under?

Tenki Sandbox MCP declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
