Retrieves detailed information about a BSV21 token by its ID (txid_vout format). Returns token data including symbol, supply, decimals, funding status, and current state.
AI agents call ordinals_getTokenByIdOrTicker 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.
This is a straightforward data retrieval tool that queries blockchain state to fetch immutable token metadata. No data is created, modified, deleted, or executed. The read-only nature and public blockchain information scope result in minimal security risk if misused by an AI agent.
From the tool's definition The tool 'retrieves detailed information' about a BSV21 token and 'Returns token data' (symbol, supply, decimals, funding status, current state). It performs a query-only operation with no modifications or side effects.
Documented attack patterns abuse exactly the kind of access ordinals_getTokenByIdOrTicker gives an agent:

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