read_log
AI agents call read_log to retrieve information from Yamcs MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name strongly suggests reading/retrieving log data from the Yamcs mission control system without side effects. While the description is empty, the name pattern and context within a telemetry-focused tool set align with Read operations. Logs are informational data for monitoring and diagnostics. Confidence is slightly reduced due to lack of description details, but the 'read_' prefix is highly indicative.
From the tool's definition Tool name 'read_log' with 'read' prefix indicates retrieval of log data. No modifying, destructive, or executing operations implied. Part of a mission control system's telemetry/logging suite alongside query tools like 'describe_alarm' and 'describe_command'.
Attacks that exploit this kind of access
read_log. It is categorised as a Read tool in the Yamcs MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Yamcs MCP Server MCP server in PolicyLayer and add a rule for read_log: 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 Yamcs MCP Server. Nothing to install.
read_log 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 read_log 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 read_log. 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.
read_log is provided by the Yamcs MCP Server MCP server (paulmramirez/yamcs-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
read_log is one line of Yamcs MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
