Check your agent's remaining credit balance and full cost table.
AI agents call get_credits to retrieve information from MCP-Networkbot without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves financial information (credit balance and cost table) but does not transfer funds, create obligations, or modify any state. It is a read-only query operation analogous to checking an account balance, which is informational rather than transactional or destructive.
From the tool's definition Tool name 'get_credits' and description 'Check your agent's remaining credit balance and full cost table' indicate a query operation that retrieves account/balance information without modifying data.
Attacks that exploit this kind of access
Check your agent's remaining credit balance and full cost table. It is categorised as a Read tool in the MCP-Networkbot MCP Server, which means it retrieves data without modifying state.
Register the MCP-Networkbot MCP server in PolicyLayer and add a rule for get_credits: 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 MCP-Networkbot. Nothing to install.
get_credits 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_credits 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_credits. 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_credits is provided by the MCP-Networkbot MCP server (kunalkhanna2007-sys/networkbot-python). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
