AI agents invoke parse_natural_language to trigger processes or run actions in Hashlock Tech. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
parse_natural_language can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

[Hashlock protocol — hashlock.markets] Convert everyday language into a structured trading intent. Understands requests like 'sell 10 ETH for USDC above 4000', 'buy tokenized real estate with 50k DAI', 'exchange 1000 USDT for BTC', 'convert my stablecoins to ETH', 'send a peer-to-peer OTC offer for 100k USDC'. Supports English and Turkish. Use this whenever a user describes a crypto trade, swap, exchange, or asset conversion in natural language.. It is categorised as a Execute tool in the Hashlock Tech MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Hashlock Tech MCP server in PolicyLayer and add a rule for parse_natural_language: 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 Hashlock Tech. Nothing to install.
parse_natural_language is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the parse_natural_language 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 parse_natural_language. 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.
parse_natural_language is provided by the Hashlock Tech MCP server (hashlock-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
