List of all inscription activity in the transaction, including their satoshi-level positioning within transactions, ordered by transaction output index. The list of inscriptions is truncated to a maximum of 10,000 inscriptions.
AI agents call inscription_activity_by_tx 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.
This tool fetches historical blockchain data (inscription activity indexed by transaction) with no side effects. It is a read-only query operation consistent with blockchain data exploration. The truncation to 10,000 results indicates pagination of existing data retrieval rather than any state-changing operation.
From the tool's definition Tool description states 'List of all inscription activity' — a pure query operation that retrieves and orders data about inscriptions within a transaction. No modification, deletion, execution, or financial operations are performed.
Documented attack patterns abuse exactly the kind of access inscription_activity_by_tx gives an agent:
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 inscription_activity_by_tx:
{
"version": "1",
"default": "deny",
"tools": {
"inscription_activity_by_tx": {}
}
}inscription_activity_by_tx is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List of all inscription activity in the transaction, including their satoshi-level positioning within transactions, ordered by transaction output index. The list of inscriptions is truncated to a maximum of 10,000 inscriptions. It is categorised as a Read tool in the Maestro MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Maestro MCP Server MCP server in PolicyLayer and add a rule for inscription_activity_by_tx: 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.
inscription_activity_by_tx is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the inscription_activity_by_tx 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 inscription_activity_by_tx. 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.
inscription_activity_by_tx 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.
Start from Maestro MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
