list_documentation_sources_tool
AI agents call list_documentation_sources_tool to retrieve information from Docy without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool lists documentation sources, which is a retrieval operation with no side effects. Despite empty description, the name pattern and sibling context strongly suggest read-only query behavior. Risk is low—enumeration of available documentation poses minimal security threat.
From the tool's definition Tool name 'list_documentation_sources_tool' indicates listing/retrieval operation; coupled with sibling tools 'fetch_document_links' and 'fetch_documentation_page' which are clearly Read operations, this tool retrieves or enumerates documentation sources…

{
"version": "1",
"default": "deny",
"tools": {
"list_documentation_sources_tool": {}
}
}list_documentation_sources_tool is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

list_documentation_sources_tool. It is categorised as a Read tool in the Docy MCP Server, which means it retrieves data without modifying state.
Register the Docy MCP server in PolicyLayer and add a rule for list_documentation_sources_tool: 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 Docy. Nothing to install.

Start from Docy, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
