AI agents call list_sites to retrieve information from Docs 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 metadata about indexed documentation sites from the SQLite database. It performs a simple enumeration/listing operation with no capacity to modify, delete, or execute anything. The worst-case misuse would be information disclosure about which sites are indexed, which is low-severity.
From the tool's definition Tool name 'list_sites' and description 'Returns every indexed site' indicate data retrieval with no modification. No deletion, execution, or side effects mentioned.

Attacks that exploit this kind of access
Returns every indexed site with its page count and last-crawled timestamp. It is categorised as a Read tool in the Docs MCP Server, which means it retrieves data without modifying state.
Register the Docs MCP server in PolicyLayer and add a rule for list_sites: 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 Docs. Nothing to install.
list_sites 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 list_sites 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 list_sites. 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.
list_sites is provided by the Docs MCP server (kage1020/docs-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
