AI agents call author_network to retrieve information from Nasa Ads without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns a coauthor network graph based on provided bibcodes. It is a read/query operation against the NASA ADS system with no writes, executions, or destructive actions. Misuse potential is minimal as it only returns informational data.
From the tool's definition 'Coauthor network graph for a set of bibcodes' — retrieves/queries network data, no side effects
Attacks that exploit this kind of access
Coauthor network graph for a set of bibcodes. It is categorised as a Read tool in the Nasa Ads MCP Server, which means it retrieves data without modifying state.
Register the Nasa Ads MCP server in PolicyLayer and add a rule for author_network: 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 Nasa Ads. Nothing to install.
author_network 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 author_network 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 author_network. 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.
author_network is provided by the Nasa Ads MCP server (mubashir1osmani/nasa-ads). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
