Why get-transaction-status needs a policy

This tool retrieves information about an existing transaction's status without modifying, executing, or deleting any data. It is a read-only operation analogous to checking status in any system. The server architecture explicitly notes that users maintain exclusive control over private keys and signing, so this tool cannot execute or finalize transactions unilaterally.

From the tool's definition Tool name is 'get-transaction-status' and description states it 'Check[s] the current status of a prepared transaction' — a pure query operation with no side effects.

POLICY

How to control get-transaction-status

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get-transaction-status": {}
  }
}

get-transaction-status is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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

FAQ

Questions about get-transaction-status

What does the get-transaction-status tool do? +

Check the current status of a prepared transaction by its id. It is categorised as a Read tool in the MCP Blockchain Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on get-transaction-status? +

Register the MCP Blockchain Server MCP server in PolicyLayer and add a rule for get-transaction-status: 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 MCP Blockchain Server. Nothing to install.

What risk level is get-transaction-status? +

Can I rate-limit get-transaction-status? +

Yes. Add a rate_limit block to the get-transaction-status 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 get-transaction-status completely? +

Set action: deny in the PolicyLayer policy for get-transaction-status. 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 get-transaction-status? +

get-transaction-status is provided by the MCP Blockchain Server MCP server (zhangzhongnan928/mcp-blockchain-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every MCP Blockchain Server tool call.

Start from MCP Blockchain Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
