## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, 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)

Scored 2026-10-22.

- **Endpoint Security**: 63/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 4 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 52/100
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 178 tokens (~44/item across 4 items; 4 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**: 67/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% 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 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 20/100
  - Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

## Install

### How do I install the Sampling Quota Guard MCP server?

Sampling Quota Guard is a hosted endpoint at https://textforagents.com/products/sampling-quota-guard/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

### 2026-10-22 (score 57)

First indexed and scored.

## MCP tools (4)

### `guard_meter` (~67 tokens)

Meter one sampling/createMessage request against your per-server ledger + fail-closed allowance + scope clamp. Billed per the pricing sheet (flat coverage, then $0.002 x402). Denied requests never consume allowance.

Input parameters:

- `request` (object, required)
- `server` (string, required)

### `guard_verdict` (~68 tokens)

Pre-connect verdict (ALLOW / CAUTION / DENY / INSUFFICIENT_DATA) for one server from your own measured profile. First 100 verdicts free one time per operator; then $0.005 x402; flat tier covers verdicts.

Input parameters:

- `server` (string, required)

### `guard_ledger` (~27 tokens)

Your per-server sampling ledger rows (your operator only).

Input parameters:

- `server` (string)

### `guard_policy` (~16 tokens)

Your allowance + tunable threshold policy.
