List all data links.
AI agents call list_links 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 retrieves and queries existing data link configuration without side effects. It is a passive information gathering operation typical of mission control telemetry interfaces. No data is created, modified, deleted, or executed. The blast radius of misuse is minimal — an AI agent could only enumerate links, not disrupt operations or modify system state.
From the tool's definition Tool name is 'list_links' and description states 'List all data links' — a read-only retrieval operation with no modification, deletion, or execution of commands.

Attacks that exploit this kind of access
List all data links. 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_links: 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_links 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_links 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_links. 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_links 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.
