## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

- **Schema Quality & AI Usability**: 72/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 757 tokens (~75/item across 10 items; 10 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 75/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 26% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 10 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 11 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

### 2026-09-19 (score 62)

First indexed and scored.

## MCP tools (10)

### `orient` (~98 tokens)

Orient in the SandboxAPIs universe

START HERE. Returns everything needed to use SandboxAPIs with no docs: the universe/theme, every API surface and its base URL (git hosts and issue trackers), live-vs-snapshot modes and how to pin, the org and its teams/repos, notable entry points (each with a ready-to-run REST path), where the coverage manifest lives, and this server's access block — whether a key is set and how many requests are left this hour.

### `check_budget` (~126 tokens)

Check the remaining request budget

Costs nothing — call it before any loop of more than a handful of requests. Returns this server's real hourly window (limit, remaining, when it resets) read from the provider's own budget endpoint, which is exempt from the budget it reports, plus whether a key is set and where to raise the limit. The window is ONE bucket per caller shared across every provider host, so the numbers apply to all of them.

Input parameters:

- `provider` (string): The host you are about to call. Optional — the budget is one shared window, so the numbers are the same for every provider.

### `list_repositories` (~45 tokens)

List the org's repositories

List repositories for the universe's org. Results are identical to the provider's REST API and carry provider-form ids (node_id / numeric id).

Input parameters:

- `provider` (string, required)

### `get_repository` (~58 tokens)

Get a repository

Fetch one repository by name (default: the flagship repo). Provider-shaped, with provider-form ids.

Input parameters:

- `provider` (string, required)
- `repo` (string): Repo name, e.g. 'parthenon'. Defaults to the flagship repo.

### `list_pull_requests` (~54 tokens)

List pull requests / merge requests

List a repo's pull requests (GitHub) or merge requests (GitLab). Optional state filter.

Input parameters:

- `provider` (string, required)
- `repo` (string)
- `state` (string): Provider state filter.

### `get_pull_request` (~72 tokens)

Get a pull/merge request with its reviews

Fetch one PR (GitHub) / MR (GitLab) plus its reviews (GitHub) / approvals (GitLab). Returns both in one result; each carries provider-form ids for cross-referencing.

Input parameters:

- `number` (integer, required)
- `provider` (string, required)
- `repo` (string)

### `list_issues` (~45 tokens)

List issues

List a repo's issues. Optional state filter (open/closed/all).

Input parameters:

- `provider` (string, required)
- `repo` (string)
- `state` (string)

### `get_user` (~50 tokens)

Get a user

Fetch a user by login/username. Provider-shaped, with provider-form ids.

Input parameters:

- `login` (string, required): The user's login (GitHub) / username (GitLab).
- `provider` (string, required)

### `search_commits_by_author` (~86 tokens)

Search commits by author

Find commits authored by a given login in a repo. Returns SHAs (identical across GitHub and GitLab, invariant #5) with a REST path to fetch each — so you can cross-reference against either provider.

Input parameters:

- `author` (string, required): Author login, e.g. 'athena'.
- `provider` (string)
- `repo` (string)

### `get_snapshot` (~49 tokens)

Get a pinned snapshot hostname

Return the pinned, reproducible hostname for a provider — point your client's base URL at it for drift-free CI. A snapshot regenerates byte-identically on every request.

Input parameters:

- `provider` (string, required)

### Is the SandboxAPIs MCP server safe to use?

SandboxAPIs scores 62 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. 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 SandboxAPIs MCP server expose?

SandboxAPIs exposes 10 tools: orient, check_budget, list_repositories, get_repository, list_pull_requests, and 5 more. Their descriptions and schemas cost roughly 683 tokens of context every time the server is loaded.

### Is the SandboxAPIs MCP server still maintained?

SandboxAPIs 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 SandboxAPIs MCP server under?

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