Check current availability and rate cards.
AI agents call mcp_check_availability to retrieve information from Atlas G Protocol without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about availability status and rate cards—data queries with no side effects. It is a passive read operation that returns existing information to the caller. No data is created, modified, deleted, or executed. Severity is low because misuse would only expose personal availability and pricing information, with no destructive or financial transaction capabilities.
From the tool's definition Tool name 'mcp_check_availability' and description 'Check current availability and rate cards' indicate querying/retrieving current status and pricing information without modifying data.
Attacks that exploit this kind of access
Check current availability and rate cards. It is categorised as a Read tool in the Atlas G Protocol MCP Server, which means it retrieves data without modifying state.
Register the Atlas G Protocol MCP server in PolicyLayer and add a rule for mcp_check_availability: 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 Atlas G Protocol. Nothing to install.
mcp_check_availability 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 mcp_check_availability 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 mcp_check_availability. 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.
mcp_check_availability is provided by the Atlas G Protocol MCP server (michaelweed/atlas-g-protocol). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
