Get the Forgejo instance NodeInfo
AI agents call get_nodeinfo to retrieve information from Forgejo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a simple read operation that queries publicly available instance metadata. It has no side effects, cannot be misused to cause damage, and represents minimal security risk. The blast radius of an AI agent misusing this tool is negligible—it can only learn non-sensitive structural information about the Forgejo instance.
From the tool's definition Tool name 'get_nodeinfo' and description 'Get the Forgejo instance NodeInfo' indicate a retrieval operation. NodeInfo is a standard protocol for exposing public metadata about a server instance (version, protocols supported, user/post counts, etc.).
Documented attack patterns abuse exactly the kind of access get_nodeinfo gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Forgejo, and nothing reaches the server without passing your rules. This is the rule we recommend for get_nodeinfo:
{
"version": "1",
"default": "deny",
"tools": {
"get_nodeinfo": {}
}
}get_nodeinfo is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the Forgejo instance NodeInfo. It is categorised as a Read tool in the Forgejo MCP Server, which means it retrieves data without modifying state.
Register the Forgejo MCP server in PolicyLayer and add a rule for get_nodeinfo: 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 Forgejo. Nothing to install.
get_nodeinfo 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 get_nodeinfo 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 get_nodeinfo. 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.
get_nodeinfo is provided by the Forgejo MCP server (sqcows/forgejo-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Forgejo, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
