WHAT IT DOES

What synthesize_extension_plan does on Nodebench

AI agents use synthesize_extension_plan to create or update resources in Nodebench, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Nodebench environment.

RISK

Why synthesize_extension_plan is rated Medium

The tool synthesizes/creates a plan document, which is a Write operation (producing new structured content). It does not execute code, delete data, or move money. Confidence is moderate because the description is vague and doesn't clarify whether 'synthesize' involves only reading/analysis or actually persisting a plan artifact.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs synthesize_extension_plan safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Nodebench, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For synthesize_extension_plan, this is the rule to start with:

synthesize_extension_plan Rate-limited

synthesize_extension_plan stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect Nodebench, apply this rule, and every synthesize_extension_plan call is checked against it from then on.

FAQ

Questions about synthesize_extension_plan

What does the synthesize_extension_plan tool do? +

Synthesize a plan for extending or deepening an existing feature. It is categorised as a Write tool in the Nodebench MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on synthesize_extension_plan? +

Register the Nodebench MCP server in PolicyLayer and add a rule for synthesize_extension_plan: 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 Nodebench. Nothing to install.

What risk level is synthesize_extension_plan? +

synthesize_extension_plan is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit synthesize_extension_plan? +

Yes. Add a rate_limit block to the synthesize_extension_plan 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.

How do I block synthesize_extension_plan completely? +

Set action: deny in the PolicyLayer policy for synthesize_extension_plan. 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.

What MCP server provides synthesize_extension_plan? +

synthesize_extension_plan is provided by the Nodebench MCP server (nodebench-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
