Full Analysis
- [EXTERNAL_DOWNLOADS]: The skill documentation instructs users to download a binary executable from
github.com/opentokenz/mcpx/releases. Because this repository belongs to an unrecognized organization, downloading and running these binaries introduces a high risk of executing unverified or potentially malicious code. - [PRIVILEGE_ESCALATION]: The installation guide suggests using
sudoto move the downloaded binary to/usr/local/bin/, granting the tool administrative placement on the system. - [COMMAND_EXECUTION]: The skill provides tools such as
command_executeandtask_startthat enable an AI agent to run arbitrary shell commands on the host machine. - [DATA_EXFILTRATION]: Tools like
screenshot_captureandenvironment_getallow for the collection of sensitive data, including screen contents and system details. Additionally,source_readprovides the ability to read arbitrary files within configured workspaces. - [INDIRECT_PROMPT_INJECTION]: The skill facilitates an attack surface where malicious data in the local environment could influence the agent's behavior.
- Ingestion points: The agent reads external content via
source_readandcontext_query(SKILL.md). - Boundary markers: No explicit delimiters or instructions are provided to help the agent distinguish between trusted instructions and untrusted file content.
- Capability inventory: The skill possesses high-impact capabilities including
command_execute,task_start, andchange_execute(SKILL.md). - Sanitization: There is no evidence of data sanitization or validation for content read from the workspace before it is presented to the agent.
