Returns the full content of the jina-docs.md documentation.
AI agents call get_help to retrieve information from Jina AI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and presents existing documentation without modifying, executing code, deleting data, or committing financial actions. It is purely informational and has minimal blast radius if misused by an AI agent - at worst, it consumes API resources or exposes public documentation already accessible through other means.
From the tool's definition Tool returns documentation content via 'get_help' - a retrieval operation with no side effects. Description states it 'Returns the full content' of documentation, which is a read-only query.
Attacks that exploit this kind of access
Returns the full content of the jina-docs.md documentation. It is categorised as a Read tool in the Jina AI MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Jina AI MCP Server MCP server in PolicyLayer and add a rule for get_help: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Jina AI MCP Server. Nothing to install.
get_help is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_help rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_help. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_help is provided by the Jina AI MCP Server MCP server (zk-armor/mcp-jina-ai). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
