AI agents call analyze_walk_forward_degradation to retrieve information from Tradeblocks without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though analyze_walk_forward_degradation only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
Run progressive walk-forward analysis to track whether out-of-sample performance is degrading relative to in-sample. Slides IS/OOS windows across trade history, computes efficiency ratios (OOS metric / IS metric) for Sharpe, win rate, and profit factor, detects trends via linear regression, and compares recent vs historical OOS efficiency. It is categorised as a Read tool in the Tradeblocks MCP Server, which means it retrieves data without modifying state.
Register the Tradeblocks MCP server in PolicyLayer and add a rule for analyze_walk_forward_degradation: 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 Tradeblocks. Nothing to install.
analyze_walk_forward_degradation 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 analyze_walk_forward_degradation 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 analyze_walk_forward_degradation. 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.
analyze_walk_forward_degradation is provided by the Tradeblocks MCP server (tradeblocks-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
