This tool retrieves Spring documentation guides. The verb 'get' and context of retrieving guide content from a documentation server are consistent with Read operations. There are no indications of data creation, modification, deletion, code execution, or financial transactions.

PolicyLayer is an MCP gateway — it sits between your AI agents and Springdocs, and nothing reaches the server without passing your rules. This is the rule we recommend for get_spring_guide:
{
"version": "1",
"default": "deny",
"tools": {
"get_spring_guide": {}
}

get_spring_guide is provided by the Springdocs MCP server (tky0065/springdocs-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Springdocs, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
