WHAT IT DOES

What tx_info does on Maestro MCP Server

AI agents call tx_info to retrieve information from Maestro MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why tx_info needs a policy

This tool queries and retrieves blockchain transaction data without side effects. It provides read-only visibility into transaction details, similar to a blockchain explorer. While Bitcoin transactions are immutable financial records, reading them carries no risk of unauthorized fund movement or state modification. The tool is informational only.

From the tool's definition Tool returns transaction information by hash, including inputs, outputs, fees, and confirmation details. The description uses retrieval language: 'Returns a full breakdown', 'useful for explorers'. No modifications, deletions, or state changes are performed.

POLICY

How to control tx_info

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "tx_info": {}
  }
}

tx_info 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 Maestro 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.

FAQ

Questions about tx_info

What does the tx_info tool do? +

Returns a full breakdown of a Bitcoin transaction by its hash. Includes inputs, outputs, fees, block confirmation details, and protocol-specific data (e.g., Ordinals, Runes, BRC20). This is useful for explorers, audit tools, or any application requiring full visibility into how funds and inscriptions are moved. It is categorised as a Read tool in the Maestro MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on tx_info? +

Register the Maestro MCP Server MCP server in PolicyLayer and add a rule for tx_info: 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 Maestro MCP Server. Nothing to install.

What risk level is tx_info? +

tx_info is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit tx_info? +

Yes. Add a rate_limit block to the tx_info 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 tx_info completely? +

Set action: deny in the PolicyLayer policy for tx_info. 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 tx_info? +

tx_info is provided by the Maestro MCP Server MCP server (maestro-org/maestro-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
