finslipa_start · Finsliparn MCP: Risk & Policy

WHAT IT DOES

What finslipa_start does on Finsliparn

AI agents invoke finslipa_start to trigger actions in Finsliparn. 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 finslipa_start needs a policy

The tool starts a session that executes an actual test suite as part of an automated refinement loop. Test execution is code execution. While the immediate action is session initialization, the tool's stated purpose is to trigger test runs and feed their results into an iterative development process. This is Execute rather than Write because it runs tests (code execution) rather than merely creating a record.

From the tool's definition Initializes a 'test-validated refinement session' that 'runs your actual test suite' and feeds results back to an LLM—this involves executing code (the test suite) and triggering automated refinement loops whose outcomes depend on the test content and LLM…

finslipa_start Rate-limited

finslipa_start 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.

FAQ

Questions about finslipa_start

What does the finslipa_start tool do? +

Initialize a new test-validated refinement session. Creates session state and initial directive. It is categorised as a Execute tool in the Finsliparn MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on finslipa_start? +

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

What risk level is finslipa_start? +

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

Can I rate-limit finslipa_start? +

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

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

finslipa_start is provided by the Finsliparn MCP server (jgabor/finsliparn). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
