Fetch a single NodeSpace node by its ID.
AI agents call nodespace_get_node to retrieve information from Nodespace without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves data from a knowledge base without modifying, deleting, or executing anything. It is a straightforward read operation that queries a local persistent context store. The server's stated purpose is to reduce token usage by enabling assistants to query project context, confirming this is a lookup tool.
From the tool's definition Tool name is 'nodespace_get_node' and description states 'Fetch a single NodeSpace node by its ID' — fetch is a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access nodespace_get_node gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Nodespace, and nothing reaches the server without passing your rules. This is the rule we recommend for nodespace_get_node:
{
"version": "1",
"default": "deny",
"tools": {
"nodespace_get_node": {}
}
}nodespace_get_node is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Fetch a single NodeSpace node by its ID. It is categorised as a Read tool in the Nodespace MCP Server, which means it retrieves data without modifying state.
Register the Nodespace MCP server in PolicyLayer and add a rule for nodespace_get_node: 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 Nodespace. Nothing to install.
nodespace_get_node 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 nodespace_get_node 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 nodespace_get_node. 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.
nodespace_get_node is provided by the Nodespace MCP server (nodespaceai/nodespace-core). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Nodespace, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
