AI agents use withdraw_stake to initiate financial transactions through Blueprint Agentic Staking (Solentic). Financial operations involve real money and are irreversible once processed. PolicyLayer blocks financial tools by default, requiring explicit human approval with transaction-level limits to prevent unauthorised spending.
withdraw_stake moves real money. Without a policy, an autonomous agent could initiate transactions that drain accounts or exceed budgets. PolicyLayer blocks financial tools by default, requiring human-in-the-loop approval with configurable spending limits per transaction and per time window.

Register the Blueprint Agentic Staking (Solentic) MCP server in PolicyLayer and add a rule for withdraw_stake: 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 Blueprint Agentic Staking (Solentic). Nothing to install.
withdraw_stake is a Financial tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the withdraw_stake 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 withdraw_stake. 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.
withdraw_stake is provided by the Blueprint Agentic Staking (Solentic) MCP server (blueprint-infrastructure/solentic-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
