prediction · Exocortex MCP: Risk & Policy

WHAT IT DOES

What prediction does on Exocortex

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

WHY IT NEEDS A POLICY

Why prediction needs a policy

This tool performs write operations by creating forecasts and resolving prediction outcomes, which are reversible modifications to data stored in the personal memory system. While it creates and updates records, there is no indication of destructive deletion, financial transactions, or code execution. The most severe applicable category is Write.

From the tool's definition Tool description states 'create forecasts' and 'resolve outcomes', indicating the tool creates and modifies prediction records.

Verdict

prediction Rate-limited

prediction 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 Exocortex, so you can run agents against it safely.

FAQ

Questions about prediction

What does the prediction tool do? +

Manage predictions: create forecasts, list/filter, resolve outcomes, get details, or view calibration stats. It is categorised as a Write tool in the Exocortex MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on prediction? +

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

What risk level is prediction? +

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

Can I rate-limit prediction? +

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

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

prediction is provided by the Exocortex MCP server (shawnhack/exocortex). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
