AI agents use assess_legacy_codebase to create or modify resources in Ui. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call assess_legacy_codebase repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Ui.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Assess a legacy codebase for migration readiness. Analyzes dependencies, architecture, security, quality, and migration readiness. Returns health score (0-100), grade (A-F), migration strategy, and detailed findings.. It is categorised as a Write tool in the Ui MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Ui MCP server in PolicyLayer and add a rule for assess_legacy_codebase: 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 Ui. Nothing to install.
assess_legacy_codebase is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the assess_legacy_codebase 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 assess_legacy_codebase. 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.
assess_legacy_codebase is provided by the Ui MCP server (@forgespace/ui-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
