Get CEP-18 fungible token balances for a Casper account. Returns all CEP-18 tokens held, or filters to a specific token if
AI agents call get_token_balance to retrieve information from CSPR[dot]trade MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a data retrieval operation only. It queries and returns token balance information for a specified Casper account without creating, modifying, deleting, or executing any irreversible actions. The operation is read-only with no blast radius beyond information disclosure.
From the tool's definition Tool name 'get_token_balance' and description 'Get CEP-18 fungible token balances for a Casper account. Returns all CEP-18 tokens held, or filters to a specific token' indicate a query operation that retrieves balance data without modification or side effects.

Get CEP-18 fungible token balances for a Casper account. Returns all CEP-18 tokens held, or filters to a specific token if. It is categorised as a Read tool in the CSPR[dot]trade MCP MCP Server, which means it retrieves data without modifying state.
Register the CSPR[dot]trade MCP server in PolicyLayer and add a rule for get_token_balance: 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 CSPR[dot]trade MCP. Nothing to install.
get_token_balance 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_balance 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_balance. 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_balance is provided by the CSPR[dot]trade MCP server (make-software/cspr-trade-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
