Why PostV1InstancesPrepareDelegateSolana needs a policy

This tool prepares and initiates a blockchain delegation transaction on Solana, which is an external operation that triggers on-chain effects. While 'prepare' suggests it may not finalize the transaction, it sets up a delegation that authorizes token transfers on a blockchain — a significant operation with real financial consequences.

From the tool's definition Prepares a delegation transaction for Solana token transfers

POLICY

How to control PostV1InstancesPrepareDelegateSolana

PolicyLayer is an MCP gateway — it sits between your AI agents and BlindPay MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for PostV1InstancesPrepareDelegateSolana:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "PostV1InstancesPrepareDelegateSolana": {
      "limits": [
        {
          "counter": "postv1instancespreparedelegatesolana_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

PostV1InstancesPrepareDelegateSolana stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register BlindPay MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
