Get $SPINE token info and the holder-gate auth flow. Returns the contract address on Base, the 5,000,000 SPINE threshold, the buy URL, and step-by-step instructions for signing in as a holder. Call this first.
AI agents call get-token-info to retrieve information from Spines Underground without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries token metadata and authentication flow information without modifying state, executing code, deleting data, or moving funds. It is a read-only operation that provides data to enable downstream authentication. The low severity reflects that misuse would only expose publicly available blockchain contract and instructional information.
From the tool's definition Tool description states it 'Returns the contract address on Base, the 5,000,000 SPINE threshold, the buy URL, and step-by-step instructions' — purely informational retrieval with 'Call this first' indicating it is a prerequisite query.

Get $SPINE token info and the holder-gate auth flow. Returns the contract address on Base, the 5,000,000 SPINE threshold, the buy URL, and step-by-step instructions for signing in as a holder. Call this first. It is categorised as a Read tool in the Spines Underground MCP Server, which means it retrieves data without modifying state.
Register the Spines Underground MCP server in PolicyLayer and add a rule for get-token-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 Spines Underground. Nothing to install.
get-token-info 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 get-token-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.
Set action: deny in the PolicyLayer policy for get-token-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.
get-token-info is provided by the Spines Underground MCP server (lisamaraventano-spine/spines-underground). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
