Medium Risk

bulk_update_categories

Add/remove categories on several tasks in one operation. 2-phase batch: GET to read existing categories, then PATCH with the updated set. Per-item errors, no global fail.

Bulk/mass operation — affects multiple targets

Part of the Mcp Microsoft Todo MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

AI agents use bulk_update_categories to create or modify resources in Mcp Microsoft Todo. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

Without a policy, an AI agent could call bulk_update_categories repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Mcp Microsoft Todo.

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

What does the bulk_update_categories tool do? +

Add/remove categories on several tasks in one operation. 2-phase batch: GET to read existing categories, then PATCH with the updated set. Per-item errors, no global fail.. It is categorised as a Write tool in the Mcp Microsoft Todo MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on bulk_update_categories? +

Add a rule in your Intercept YAML policy under the tools section for bulk_update_categories. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Mcp Microsoft Todo MCP server.

What risk level is bulk_update_categories? +

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

Can I rate-limit bulk_update_categories? +

Yes. Add a rate_limit block to the bulk_update_categories rule in your Intercept 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 bulk_update_categories completely? +

Set action: deny in the Intercept policy for bulk_update_categories. 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 bulk_update_categories? +

bulk_update_categories is provided by the Mcp Microsoft Todo MCP server (@mag-cie/mcp-microsoft-todo). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
