List all processors.
AI agents call list_processors 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.
This tool queries and returns information about processors in the Yamcs mission control system. It performs no mutations, deletions, or command executions—it simply enumerates existing processors. This is a standard read operation with minimal security risk.
From the tool's definition Tool name 'list_processors' and description 'List all processors' indicate a data retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
List all processors. 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 list_processors: 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.
list_processors 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 list_processors 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 list_processors. 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.
list_processors 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.
list_processors 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.
