WHAT IT DOES

What bap_getId does on Bitcoin SV MCP Server

AI agents call bap_getId to retrieve information from Bitcoin SV 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 bap_getId needs a policy

The tool retrieves identity profile information from the blockchain using an idKey parameter. This is a query/lookup operation with no ability to modify, delete, execute arbitrary code, or commit financial transactions. The blast radius of misuse is minimal—worst case would be retrieving identity information that is already public on the blockchain.

From the tool's definition Tool name 'bap_getId' and description 'Retrieves a Bitcoin Attestation Protocol (BAP) identity profile' explicitly indicate a read operation that fetches data without modification or side effects.

Documented attack patterns abuse exactly the kind of access bap_getId gives an agent:

POLICY

How to control bap_getId

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

policy.json

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

bap_getId 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 Bitcoin SV 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.
