抓取 Micro-app 相关文档内容
AI agents call crawl_micro_app_docs to retrieve information from Micro without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool crawls and retrieves documentation content, which is a read-only operation with no side effects. It queries existing documentation without modifying, deleting, or executing any operations. The low severity reflects that documentation retrieval has minimal blast radius even if misused by an AI agent.
From the tool's definition Tool name contains 'crawl' and description states '抓取 Micro-app 相关文档内容' (retrieve/crawl Micro-app related documentation content). The sibling tool 'get_related_links' further confirms this is a data retrieval server.
Documented attack patterns abuse exactly the kind of access crawl_micro_app_docs gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Micro, and nothing reaches the server without passing your rules. This is the rule we recommend for crawl_micro_app_docs:
{
"version": "1",
"default": "deny",
"tools": {
"crawl_micro_app_docs": {}
}
}crawl_micro_app_docs is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

抓取 Micro-app 相关文档内容. It is categorised as a Read tool in the Micro MCP Server, which means it retrieves data without modifying state.
Register the Micro MCP server in PolicyLayer and add a rule for crawl_micro_app_docs: 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 Micro. Nothing to install.
crawl_micro_app_docs 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 crawl_micro_app_docs 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 crawl_micro_app_docs. 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.
crawl_micro_app_docs is provided by the Micro MCP server (jd-opensource/microapp-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Micro, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
