Get a single card by Scryfall UUID or by name (exact/fuzzy).
AI agents call get_card to retrieve information from Scryfall MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves card data from the Scryfall API without modifying, deleting, or executing any operations. It is a straightforward query that returns card information based on identifier or name matching. No data creation, modification, or irreversible action is possible. The blast radius of misuse is minimal—an agent could only retrieve unwanted card data, which poses no security or operational risk.
From the tool's definition Tool description states 'Get a single card' by UUID or name — a retrieval operation with no side effects. The verb 'Get' and the context of querying Magic: The Gathering card data confirm this is a lookup/fetch action.
Attacks that exploit this kind of access
Get a single card by Scryfall UUID or by name (exact/fuzzy). It is categorised as a Read tool in the Scryfall MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Scryfall MCP Server MCP server in PolicyLayer and add a rule for get_card: 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 Scryfall MCP Server. Nothing to install.
get_card 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_card 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_card. 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_card is provided by the Scryfall MCP Server MCP server (latte-chan/scryfall-connector). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
