Security Findings2

Severity	Finding	Layer	Location
MEDIUM	Unpinned MCP dependency The skill's manifest specifies a dependency on the 'rube' MCP without a pinned version. This means the skill could automatically use any version of the Rube MCP, potentially introducing breaking changes or malicious behavior if the MCP provider's infrastructure is compromised or if an undesirable update is pushed. The skill also explicitly points to 'https://rube.app/mcp' as the source, which could be a single point of failure or compromise. Pin the version of the 'rube' MCP in the manifest to ensure deterministic and secure dependency resolution. For example, `"mcp": ["rube@1.2.3"]` or similar versioning scheme if supported by the ecosystem. Additionally, consider implementing integrity checks for external MCP sources.	Static	SKILL.md:5
MEDIUM	Broad tool execution capability via RUBE_REMOTE_WORKBENCH The skill instructs the agent to use `RUBE_REMOTE_WORKBENCH` for 'Bulk ops' with `run_composio_tool()`. This suggests a powerful and potentially unconstrained execution environment within the Rube MCP. If the underlying `run_composio_tool()` allows arbitrary or very broad operations on the Helcim account, and the agent is not sufficiently constrained by its own policies, this could lead to excessive permissions being exercised, potentially performing unintended or harmful bulk operations. If possible, define more granular permissions or scope for the `RUBE_REMOTE_WORKBENCH` tool within the Rube MCP, or provide clearer instructions to the agent on when and how to use this powerful tool. Agents should be designed with robust authorization checks before executing broad operations.	Static	SKILL.md:70
