compute_set_pricing · Tenzro Ledger MCP: Risk & Policy

WHAT IT DOES

What compute_set_pricing does on Tenzro Ledger MCP

AI agents use compute_set_pricing to create or update resources in Tenzro Ledger MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Tenzro Ledger MCP environment.

WHY IT NEEDS A POLICY

Why compute_set_pricing needs a policy

This tool creates or modifies pricing data (pricing policy configuration). It does not delete data irreversibly (not Destructive), does not move money directly (not Financial), and does not execute arbitrary code (not Execute). The 'set' operation and focus on 'pricing policy' indicate Write-category data modification.

From the tool's definition Tool name 'compute_set_pricing' and description 'Set the per-epoch compute pricing policy' indicate the tool modifies pricing configuration, which is a reversible change to system state.

Verdict

compute_set_pricing Rate-limited

compute_set_pricing 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 Tenzro Ledger MCP, so you can run agents against it safely.

FAQ

Questions about compute_set_pricing

What does the compute_set_pricing tool do? +

Set the per-epoch compute pricing policy. It is categorised as a Write tool in the Tenzro Ledger MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on compute_set_pricing? +

Register the Tenzro Ledger MCP server in PolicyLayer and add a rule for compute_set_pricing: 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_set_pricing? +

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

Can I rate-limit compute_set_pricing? +

Yes. Add a rate_limit block to the compute_set_pricing 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_set_pricing completely? +

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

compute_set_pricing 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.
