Validate assumptions or statements using agreement-based evaluation when you already have context about the situation. Use for testing theories, predictions, or proposals that can be rated as true/false or good/bad. Choose this when you need expert judgment on specific claims, not general questions.
AI agents call challenge-hypothesis to retrieve information from AskMeMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool pauses execution to request human input/judgment on a hypothesis — it reads/retrieves a human's evaluation of a claim. It does not modify data, execute code, delete anything, or move money. The core action is soliciting a boolean or rating response from a human, which is fundamentally a read/query operation on human knowledge.

Validate assumptions or statements using agreement-based evaluation when you already have context about the situation. Use for testing theories, predictions, or proposals that can be rated as true/false or good/bad. Choose this when you need expert judgment on specific claims, not general questions. It is categorised as a Read tool in the AskMeMCP MCP Server, which means it retrieves data without modifying state.
Register the AskMe MCP server in PolicyLayer and add a rule for challenge-hypothesis: 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 AskMeMCP. Nothing to install.
challenge-hypothesis is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the challenge-hypothesis 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 challenge-hypothesis. 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.
challenge-hypothesis is provided by the AskMe MCP server (thlandgraf/askme-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
