compile_bp_program · UOFast MCP: Risk & Policy

WHAT IT DOES

What compile_bp_program does on UOFastMCP

AI agents invoke compile_bp_program to trigger actions in UOFastMCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why compile_bp_program needs a policy

Compilation of user-supplied code is an Execute action because it triggers external processing (the BASIC compiler) whose effects depend on the program arguments provided. While compilation itself may be less immediately dangerous than execution, it can trigger side effects during compilation (e.g., pre-compilation hooks, macro expansion, or resource consumption) and enables downstream execution of compiled code.

From the tool's definition Tool description states it "Compile[s] a UniData BP (Basic Program) using the BASIC command" and "Returns compilation output including any errors." The name 'compile_bp_program' and reference to executing the BASIC command indicate code compilation/execution.

Verdict

compile_bp_program Rate-limited

compile_bp_program stays usable, but rate-capped — a runaway agent can't fire it dozens of times 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 UOFastMCP, so you can run agents against it safely.

FAQ

Questions about compile_bp_program

What does the compile_bp_program tool do? +

Compile a UniData BP (Basic Program) using the BASIC command. Returns compilation output including any errors. It is categorised as a Execute tool in the UOFastMCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on compile_bp_program? +

Register the UOFast MCP server in PolicyLayer and add a rule for compile_bp_program: 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 UOFastMCP. Nothing to install.

What risk level is compile_bp_program? +

compile_bp_program is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit compile_bp_program? +

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

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

compile_bp_program is provided by the UOFast MCP server (rokipark/uofastmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
