compute_settle_epoch · Tenzro Ledger MCP: Risk & Policy

WHAT IT DOES

What compute_settle_epoch does on Tenzro Ledger MCP

AI agents use compute_settle_epoch to commit financial operations through Tenzro Ledger MCP — usually the final step of a payment, billing, or trading workflow. A call moves real money.

WHY IT NEEDS A POLICY

Why compute_settle_epoch needs a policy

Settling an epoch of a compute rental is a financial operation that likely moves funds or commits payment for services rendered. The presence of 'availability proof' gating suggests a verified financial settlement mechanism.

From the tool's definition 'Settle one epoch of an active compute rental' — settling a rental epoch involves committing a financial obligation or payment for compute resources consumed.

FAQ

Questions about compute_settle_epoch

What does the compute_settle_epoch tool do? +

Settle one epoch of an active compute rental, gated on the availability proof. It is categorised as a Financial tool in the Tenzro Ledger MCP MCP Server, which means it involves financial transactions. Block by default and require explicit approval.

How do I enforce a policy on compute_settle_epoch? +

Register the Tenzro Ledger MCP server in PolicyLayer and add a rule for compute_settle_epoch: 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 Tenzro Ledger MCP. Nothing to install.

What risk level is compute_settle_epoch? +

compute_settle_epoch is a Financial tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit compute_settle_epoch? +

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

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

compute_settle_epoch is provided by the Tenzro Ledger MCP server (https://canton-mcp.tenzro.network/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
