WHAT IT DOES

What spl-token_freezeAccount does on Sap

AI agents invoke spl-token_freezeAccount to trigger actions in Sap. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

Parameter	Type	Required	Description
`mint`	string	Yes	Token mint address (base58)
`account`	string	Yes	Token account to freeze
`freezeAuthority`	string	Yes	Freeze authority wallet

Parameters from the server's own tool schema.

RISK

Why spl-token_freezeAccount is rated High

RECOMMENDED RULE

The rule that runs spl-token_freezeAccount safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Sap, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For spl-token_freezeAccount, this is the rule to start with:

spl-token_freezeAccount Rate-limited

spl-token_freezeAccount 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.

FAQ

Questions about spl-token_freezeAccount

What does the spl-token_freezeAccount tool do? +

Freeze a token account (prevents all transfers). Requires freeze authority. SAP MCP context: Protocol spl-token; operation class write. Use for SPL token deploy, mint, transfer, burn, freeze, thaw, and authority management. Confirm mint, decimals, authority, recipient, and amount before writes. Use token tools alongside SAP payments and settlement tools only when token operations are part of the agent service lifecycle. SAP MCP execution guidance: Intent: SAP MCP tool workflow. Pricing: paid read-premium; estimate first, then use sap_payments_call_paid_tool when the runtime cannot replay x402 natively. Routing: hosted accountless write is blocked; do not call this as a paid hosted write and no x402 payment should be charged. Use the local sap_payments bridge or a hosted unsigned builder when user signing is required. Signer boundary: user-controlled local profile or external signer; OOBE hosted MCP remains non-custodial. It is categorised as a Execute tool in the Sap MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

What parameters does spl-token_freezeAccount accept? +

spl-token_freezeAccount accepts 3 parameters: mint, account, freezeAuthority. Required: mint, account, freezeAuthority. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on spl-token_freezeAccount? +

Register the Sap MCP server in PolicyLayer and add a rule for spl-token_freezeAccount: 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 Sap. Nothing to install.

What risk level is spl-token_freezeAccount? +

Can I rate-limit spl-token_freezeAccount? +

Yes. Add a rate_limit block to the spl-token_freezeAccount 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.

How do I block spl-token_freezeAccount completely? +

Set action: deny in the PolicyLayer policy for spl-token_freezeAccount. 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.

What MCP server provides spl-token_freezeAccount? +
