AI agents call yapi_list_projects to retrieve information from Yapi Auto MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves a list of projects with their IDs and names. It has no side effects, does not modify data, and does not trigger external operations. It is a straightforward read/retrieval operation consistent with the Read category.
From the tool's definition Tool name 'yapi_list_projects' and description '列出YApi的项目ID(projectId)和项目名称' (translates to 'List YApi project IDs and project names') indicate retrieval of project metadata without modification.
Documented attack patterns abuse exactly the kind of access yapi_list_projects gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Yapi Auto MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for yapi_list_projects:
{
"version": "1",
"default": "deny",
"tools": {
"yapi_list_projects": {}
}
}yapi_list_projects is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

列出YApi的项目ID(projectId)和项目名称. It is categorised as a Read tool in the Yapi Auto MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Yapi Auto MCP Server MCP server in PolicyLayer and add a rule for yapi_list_projects: 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 Yapi Auto MCP Server. Nothing to install.
yapi_list_projects 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 yapi_list_projects 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 yapi_list_projects. 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.
yapi_list_projects is provided by the Yapi Auto MCP Server MCP server (lzsheng/yapi-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Yapi Auto MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
