Get comprehensive information about a processor.
AI agents call describe_processor 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 retrieves and queries data about a processor in a Yamcs mission control system. The verb 'describe' and 'get information' are characteristic of read-only operations that do not modify, delete, or execute any actions. There is no indication of data mutation, deletion, or external operation triggering.
From the tool's definition Tool name 'describe_processor' and description 'Get comprehensive information about a processor' indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
Get comprehensive information about a processor. 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 describe_processor: 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.
describe_processor 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 describe_processor 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 describe_processor. 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.
describe_processor 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.
