## 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 2026-10-23.

- **Endpoint Security**: 69/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - 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**: 55/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 2639 tokens (~439/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 20/100
  - Stability observed for 6 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 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.

### `grandet_find_cheapest_api` (~822 tokens)

Find a suitable low-cost model API / 寻找便宜且适用的模型 API

Compare Grandet model prices within each unit. Read listings for price-only ordering and conditions; legacy recommended/alternative/cheapest retain their old meanings. Use view=compact for shared connection cards and a short text response. Provide exactly one model or name selector. host records the source only and never selects the inference route. Send targetApp when the user or conversation identifies the intended API application, including explicit use in the current app. With no target, compare directly. An unrecorded app connection permits a price-only recommendation, not a compatibility claim. Omit profile/protocol for a multi-protocol app unless already specified. Existing client remains a legacy target-app alias. Infer coding/chat/long_output from the task; presets are estimates. Use grandet_list_apps only when application facts are needed. Do not request API keys.

Input parameters:

- `asOf` (string): Evaluate as of this UTC time (ISO 8601, e.g. "2026-10-16T12:00:00Z"). Omit to evaluate now.
- `channel` (string): "standard" (default) lists ordinary channels, "declared-nonstandard" only channels the site itself labels nonstandard, "all" both.
- `client` (string): Legacy alias of targetApp. Prefer targetApp.
- `currency` (string): Limit to one unit board: USD_CREDIT or CNY_CREDIT (site credit, not cash), USD or CNY (cash). Never compare prices across units.
- `endpointType` (string): Limit to one API protocol. Send it only when the user named a protocol.
- `host` (string): The assistant or app making this call, e.g. "claude-code" or "codex". Attribution only; it does not change results.
- `lang` (string): Answer language: "en" or "zh-CN".
- `limit` (integer): Rows per block, 1–20 (default 5).
- `mix` (string): Workload used to blend input, cache and output prices into one price per million total tokens. Presets "chat" (default), "coding" and "long_output", or custom input/cache-read/output/cache-write shar…
- `model` (string): Model to look up: a catalogue ID, an exact model name or a natural name such as "claude-sonnet-5-5". Send exactly one of model or name. An ambiguous name returns NEEDS_CLARIFICATION with candidates.
- `name` (string): The catalogue's 20-character hexadecimal raw-name ID (not the name text). Send exactly one of model or name.
- `os` (string): Operating system the target app runs on, for connection steps: windows, macos, linux or unknown.
- `plans` (string): "best" (default) keeps one group per site; "all" lists every group of every site.
- `releaseSet` (string): Pin a published data release by its release-set hash. Omit to use the current release.
- `skillBuild` (string): Grandet Skill build ID when called from the Skill. Omit otherwise.
- `skillVersion` (string): Grandet Skill version when called from the Skill, e.g. "0.3.0". Omit otherwise.
- `targetApp` (string): Catalogue ID of the app that will use the API, e.g. "openclaw", "claude-code" or "codex". Selects compatible protocols and connection steps. Send it only when the user says where the API will be used.
- `targetProfile` (string): An inference profile ID of the target app (see grandet_list_apps). Only together with targetApp or client.
- `view` (string): "compact" (default): a short text summary plus the listings, with connection cards shared in integrationCards; about a third of the size. "full": every legacy field, with the whole JSON repeated as t…

### `grandet_list_apps` (~252 tokens)

Grandet application profiles / Grandet 应用接入清单

Read the shared Grandet application list and inference profiles before selecting a supplier. App profiles determine API compatibility; MCP capability alone does not prove an inference route or Skill installation. Use only when the target app ID, supported protocol or configuration variant is uncertain.

Input parameters:

- `app` (string): Catalogue app ID to show, e.g. "openclaw". Omit to list every app.
- `host` (string): The assistant or app making this call, e.g. "claude-code" or "codex". Attribution only; it does not change results.
- `lang` (string): Answer language: "en" or "zh-CN".
- `skillBuild` (string): Grandet Skill build ID when called from the Skill. Omit otherwise.
- `skillVersion` (string): Grandet Skill version when called from the Skill, e.g. "0.3.0". Omit otherwise.
- `targetApp` (string): Catalogue ID of the app that will use the API, e.g. "openclaw", "claude-code" or "codex". Selects compatible protocols and connection steps. Send it only when the user says where the API will be used.

Output parameters:

- `apps` (array)
- `schema` (string)

### `grandet_resolve_model` (~258 tokens)

Resolve a model name / 识别模型名称

Look up public model identifiers when a requested name is ambiguous. Results are a page of candidates, not a cheapest-provider ranking. Prefer an exact officialId match; do not silently substitute a different model generation.

Input parameters:

- `host` (string): The assistant or app making this call, e.g. "claude-code" or "codex". Attribution only; it does not change results.
- `lang` (string): Answer language: "en" or "zh-CN".
- `name` (string, required): Model name text to look up, e.g. "sonnet" or "deepseek v4".
- `page` (integer): Result page, starting at 1.
- `skillBuild` (string): Grandet Skill build ID when called from the Skill. Omit otherwise.
- `skillVersion` (string): Grandet Skill version when called from the Skill, e.g. "0.3.0". Omit otherwise.
- `targetApp` (string): Catalogue ID of the app that will use the API, e.g. "openclaw", "claude-code" or "codex". Selects compatible protocols and connection steps. Send it only when the user says where the API will be used.

Output parameters:

- `candidates` (array)
- `help` (object)
- `pagination` (object)
- `schema` (string)
- `status`

### `grandet_quote_evidence` (~465 tokens)

Inspect a provider quote / 查看报价依据

Read one provider's paged public declarations for a model and optional rowId. Use only when a detail matters, not before every recommendation. A missing row on one page is not proof of absence; follow pagination if needed. This does not test model quality or spend money.

Input parameters:

- `asOf` (string): Evaluate as of this UTC time (ISO 8601, e.g. "2026-10-16T12:00:00Z"). Omit to evaluate now.

- `lang` (string): Answer language: "en" or "zh-CN".
- `model` (string): Model to look up: a catalogue ID, an exact model name or a natural name such as "claude-sonnet-5-5". Send exactly one of model or name. An ambiguous name returns NEEDS_CLARIFICATION with candidates.
- `name` (string): The catalogue's 20-character hexadecimal raw-name ID (not the name text). Send exactly one of model or name.
- `offerPage` (integer): Page of this provider's declarations, starting at 1. Follow it when rowId is absent.
- `provider` (string, required): The sourceId of the row to inspect (the site host, e.g. "api.example.com"), not the operator ID.
- `releaseSet` (string): Pin a published data release by its release-set hash. Omit to use the current release.
- `rowId` (string): The rowId of the selected row, to read that exact declaration.
- `skillBuild` (string): Grandet Skill build ID when called from the Skill. Omit otherwise.
- `skillVersion` (string): Grandet Skill version when called from the Skill, e.g. "0.3.0". Omit otherwise.

- `rows` (array)
- `schema` (string)
- `websiteUrl` (string)

### `grandet_glossary` (~285 tokens)

Relay terminology / 中转站术语

Look up the published Grandet relay glossary. Site labels are source claims and glossary terms explain them; they do not verify quality. Query q or category and follow pagination. Unknown terms include up to three related FAQ links.

- `pagination` (object)
- `schema` (string)
- `suggestions` (array)
- `terms` (array)

### `grandet_find_free_credits` (~449 tokens)

Find free API credit / 查找免费 API 额度

Find current official free tiers, application-based credits and relay free groups. Return the stated benefit, six requirements, deadline, original observation and claim link. userCanMeet=no_card excludes explicit required/conditional card entries; unknown card requirements remain clearly labelled unknown. Application categories describe programs, not the user’s eligibility. Follow pagination.

Input parameters:

- `asOf` (string): Evaluate as of this UTC time (ISO 8601, e.g. "2026-10-16T12:00:00Z"). Omit to evaluate now.
