tool_set_axis_format · origin- MCP: Risk & Policy

WHAT IT DOES

What tool_set_axis_format does on origin-MCP

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

WHY IT NEEDS A POLICY

Why tool_set_axis_format needs a policy

This tool modifies the visual representation of a graph by changing axis formatting parameters. While it alters the graph's state, these changes are reversible (axis properties can be reformatted again). The modification does not delete data, execute external commands, or trigger financial transactions. It is therefore classified as Write rather than Execute or Destructive.

From the tool's definition tool_set_axis_format formats axis properties (scale type, range, ticks, grid) — it modifies graph configuration reversibly without deleting data or executing arbitrary code.

Verdict

tool_set_axis_format Rate-limited

tool_set_axis_format 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.

FAQ

Questions about tool_set_axis_format

What does the tool_set_axis_format tool do? +

Format axis scale type, range, ticks, and grid for a graph. It is categorised as a Write tool in the origin-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 tool_set_axis_format? +

Register the origin- MCP server in PolicyLayer and add a rule for tool_set_axis_format: 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 origin-MCP. Nothing to install.

What risk level is tool_set_axis_format? +

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

Can I rate-limit tool_set_axis_format? +

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

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

tool_set_axis_format is provided by the origin- MCP server (zhang-923-ze/origin-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
