Probe each upstream oracle source (Pyth, Chainlink, aggregator) with
AI agents call get_sources_status to retrieve information from OracleForge MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries the status of external oracle sources to check their health and availability. It performs a read-only inspection ('probe') of upstream data sources with no side effects, no data modification, no code execution, and no financial operations. The action is non-destructive information retrieval typical of monitoring and observability tools.
From the tool's definition Tool name 'get_sources_status' and description 'Probe each upstream oracle source' indicate a diagnostic/monitoring query that retrieves status information without modification.
Attacks that exploit this kind of access
Probe each upstream oracle source (Pyth, Chainlink, aggregator) with. It is categorised as a Read tool in the OracleForge MCP MCP Server, which means it retrieves data without modifying state.
Register the OracleForge MCP server in PolicyLayer and add a rule for get_sources_status: 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 OracleForge MCP. Nothing to install.
get_sources_status 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_sources_status 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_sources_status. 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_sources_status is provided by the OracleForge MCP server (maxiaworld/oracleforge). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
