What error_resolve does on Yaver
AI agents use error_resolve to create or update resources in Yaver, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Yaver environment.
| Parameter | Type | Required | Description |

Why error_resolve is rated Medium
This tool modifies the state of an error record from unresolved to resolved (update operation). The change is reversible—the record remains in the ledger and could theoretically be reopened. This qualifies as Write rather than Destructive. The blast radius is minimal: marking errors as resolved in a local dev environment has no external impact, no data loss, and no financial consequences.
From the tool's definition Tool description states 'Mark an error as resolved' and 'The record stays in the ledger but drops off the open-errors view', indicating a state change to an existing record (reversible update).
Attacks that exploit this kind of access
The rule that runs error_resolve safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Yaver, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For error_resolve, this is the rule to start with:
error_resolve 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Yaver, apply this rule, and every error_resolve call is checked against it from then on.
Questions about error_resolve
Mark an error as resolved with an optional note. The record stays in the ledger but drops off the open-errors view. It is categorised as a Write tool in the Yaver MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
error_resolve accepts 2 parameters: note, fingerprint. Required: fingerprint. The full parameter table on this page comes from the server's own tool schema.
Register the Yaver MCP server in PolicyLayer and add a rule for error_resolve: 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 Yaver. Nothing to install.
error_resolve 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 error_resolve 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 error_resolve. 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.
error_resolve is provided by the Yaver MCP server (yaver-cli). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
