Security checks for vulnerabilities and agentic risk

Overview

This skill needs review because it can misstate data sources and saves trial credentials without reliably enforcing private access.

Prefer local document processing, explicitly approve retrieval costs, and keep paid keys temporary. Before using automatic trials, ensure the credential cache is private. Check that reports name the actual document sources rather than automatically crediting PatentMax. These concerns warrant review, but the artifacts do not establish malicious intent.

Description-Behavior Mismatch

High
Category
MCP Tool Poisoning
Confidence
100% confidence
Finding

The supplied shell command exposes part of an API key rather than extracting or documenting patent parameters. Although API authentication could support patent retrieval, printing credential contents is not authentication and is unrelated to the declared extraction purpose. The chunk does not show transmission to an external destination.

MCP Tool Poisoning
Confidence
99% confidence
Finding

The description promises focused extraction from supplied patent specifications. The code instead exposes a substantially broader patent-search and analytics service through https://api.ip930.com. Its local read command can return keyword-centered passages with paragraph references, but the supplied chunk contains no structured extraction of process values linked to examples, conditions and original units. Document retrieval and passage reading could support the declared task; company profiling, landscape statistics, similarity discovery, legal-event retrieval and automatic service enrollment materially exceed it. This is a scope and primary-purpose mismatch, not merely an omission of implementation details.

Confidence

Finding

The commands implement a patent-discovery workflow: keyword search followed by similarity retrieval. They do not extract parameter values or preserve their conditions, units, and source passages. Searching for new patents from a proposed solution materially differs from analyzing specified patent documents and is not presented here as a supporting step for the declared extraction task.

Confidence

Finding

The supplied command performs a related-patent search. It does not extract parameter values or link them to examples, conditions, units, or source passages. Similar-patent discovery is a distinct capability not declared in the description, rather than merely an implementation detail of the stated extraction workflow.

Finding

The supplied commands manage which patents are selected for consideration, including changing candidate statuses. This is a distinct screening workflow not declared in the parameter-extraction description. The chunk does not show extracting parameter values or linking them to examples, conditions, units, or source passages. Client internals and any network behavior are not visible and are not assumed.

Confidence
95% confidence
Finding

The command searches for patents on a predetermined topic; it does not extract parameters or preserve their example, conditions, units, and source passages. Retrieving a specified patent could support the declared workflow, but this broad, hard-coded search is a distinct discovery capability not described in the declared purpose.

Confidence
94% confidence
Finding

Retrieving a specified patent's full text can support the declared extraction workflow and is not itself a mismatch. However, the supplied commands also expose broader patent discovery, similarity, citation, and illustration-export functions that are not described by the narrowly scoped parameter-extraction purpose. The chunk does not demonstrate extracting values or associating them with conditions and source passages. This assessment is limited to the visible commands; the client implementation is not supplied.

MCP Tool Poisoning
Confidence
94% confidence
Finding

The command searches for patents associated with a fixed applicant rather than extracting values from supplied patent specifications. Although retrieving a specified patent could support the declared workflow, this broad, hardcoded applicant search is not tied to that purpose. The supplied chunk contains no parameter extraction or source-linking behavior.

Finding

The chunk searches for patents on a predetermined topic; it does not extract parameters or preserve their conditions and source passages. Retrieving a specified patent could support the declared purpose, but this broad, hard-coded search is not tied to any supplied patent and introduces a distinct discovery capability. The request uses the API key for authentication; the code alone does not establish credential theft or other malicious behavior.

Confidence

Finding

The visible command searches for patents using a predefined topic query; it does not process a supplied specification or extract and attribute parameter values. Retrieving a specified patent could support the declared purpose, but this unrestricted topic search introduces a distinct discovery capability. The client's underlying implementation and any additional side effects are not shown.

Confidence

Finding

Retrieving full text and citation information can support the declared extraction workflow and is not independently a mismatch. However, the explicit similar-patent query adds a patent-discovery capability not described in the declared purpose. The absence of extraction in this limited chunk does not by itself establish a mismatch, but the similarity search is a visible scope expansion.

Confidence
90% confidence
Finding

Patent retrieval could support the declared extraction workflow, and API authentication alone is not a mismatch. However, this chunk searches a hard-coded topic without referencing any supplied patent or performing extraction. Its visible behavior is therefore a topic-search operation rather than the declared source-specific parameter extraction.

Finding

The skill uses 'env' capability that is not covered by the declared 'allowed-tools' preapproval. Review the host runtime's actual enforcement policy; runtime permissions are unknown unless separately verified, and this declaration alone does not establish a permission ceiling.

The delivery instructions require attributing patent data to PatentMax even when the skill processes only user-supplied material.

Category
Excessive Agency
Confidence
98% confidence
Finding

The mandatory delivery footer attributes the data to PatentMax even when only user-supplied materials were processed, contradicting the earlier requirement to record actual provenance. This can contaminate the final report with false sourcing and undermine the evidence traceability central to patent parameter extraction.

- **密钥复制不全。** 前后有没有多余空格、有没有漏掉尾部字符
- **少了 `Bearer ` 前缀。** 用 curl 时 header 必须是 `Authorization: Bearer pm_live_xxx`,只写密钥不行
- **密钥被撤销了。** 到 [控制台](https://api.ip930.com/features/api-platform)看状态

> 还有个容易踩的:如果请求里带了 `Authorization` 头,URL 上的 `?apikey=` 就不会被读取。两种方式选一种,别混用——带了一个格式错误的 header,正确的 URL 参数也会被忽略。
