scaffold_project · Recon Fuzz Chimera MCP: Risk & Policy

WHAT IT DOES

What scaffold_project does on Recon Fuzz Chimera

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

WHY IT NEEDS A POLICY

Why scaffold_project needs a policy

This tool generates and writes project files (scaffolding a test suite), which is a file creation/write operation. It creates new files on disk but does not execute code, delete data, or involve financial transactions. The blast radius is medium since it could overwrite existing project files depending on implementation.

Verdict

scaffold_project Rate-limited

scaffold_project 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Recon Fuzz Chimera, so you can run agents against it safely.

FAQ

Questions about scaffold_project

What does the scaffold_project tool do? +

Scaffold a complete Chimera fuzzing test suite for a given contract and its functions. Returns an array of {path, content} for all project files. It is categorised as a Write tool in the Recon Fuzz Chimera MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on scaffold_project? +

Register the Recon Fuzz Chimera MCP server in PolicyLayer and add a rule for scaffold_project: 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 Recon Fuzz Chimera. Nothing to install.

What risk level is scaffold_project? +

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

Can I rate-limit scaffold_project? +

Yes. Add a rate_limit block to the scaffold_project 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 scaffold_project completely? +

Set action: deny in the PolicyLayer policy for scaffold_project. 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 scaffold_project? +

scaffold_project is provided by the Recon Fuzz Chimera MCP server (recon-fuzz/recon-mcp-chimera). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
