Returns a list of transaction IDs in a block, given the block hash.
AI agents call getBtcBlockTxids to retrieve information from Agentek Eth without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query of publicly available blockchain transaction data. It retrieves information (transaction IDs) based on a block hash parameter, with no side effects, state changes, or ability to execute operations. The severity is low because even if called maliciously, it only exposes immutable historical blockchain data already publicly visible.
From the tool's definition Tool name 'getBtcBlockTxids' and description 'Returns a list of transaction IDs in a block' indicate a query operation that retrieves blockchain data without modification or execution.
Documented attack patterns abuse exactly the kind of access getBtcBlockTxids gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Agentek Eth, and nothing reaches the server without passing your rules. This is the rule we recommend for getBtcBlockTxids:
{
"version": "1",
"default": "deny",
"tools": {
"getBtcBlockTxids": {}
}
}getBtcBlockTxids is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Returns a list of transaction IDs in a block, given the block hash. It is categorised as a Read tool in the Agentek Eth MCP Server, which means it retrieves data without modifying state.
Register the Agentek Eth MCP server in PolicyLayer and add a rule for getBtcBlockTxids: 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 Agentek Eth. Nothing to install.
getBtcBlockTxids 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 getBtcBlockTxids 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 getBtcBlockTxids. 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.
getBtcBlockTxids is provided by the Agentek Eth MCP server (nanidao/agentek). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Agentek Eth, 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.
