cortex_resolve_contradiction · Cortex MCP: Risk & Policy

WHAT IT DOES

What cortex_resolve_contradiction does on Cortex MCP

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

WHY IT NEEDS A POLICY

Why cortex_resolve_contradiction needs a policy

This tool creates or modifies data by selecting and keeping one version while implicitly discarding another. It has Write characteristics because the change is reversible and depends on deliberate user input to choose which version persists.

From the tool's definition Tool description states 'Resolve a contradiction by choosing which version to keep,' indicating it modifies or overwrites data based on user choice.

Verdict

cortex_resolve_contradiction Rate-limited

cortex_resolve_contradiction 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 Cortex MCP, so you can run agents against it safely.

FAQ

Questions about cortex_resolve_contradiction

What does the cortex_resolve_contradiction tool do? +

Resolve a contradiction by choosing which version to keep. It is categorised as a Write tool in the Cortex 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 cortex_resolve_contradiction? +

Register the Cortex MCP server in PolicyLayer and add a rule for cortex_resolve_contradiction: 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 Cortex MCP. Nothing to install.

What risk level is cortex_resolve_contradiction? +

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

Can I rate-limit cortex_resolve_contradiction? +

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

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

cortex_resolve_contradiction is provided by the Cortex MCP server (neuralnexustech/cortex-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
