AI agents call get_interaction_network to retrieve information from Gwas without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries a biological database (STRING) to retrieve pre-computed protein interaction data. It reads and returns information without creating, modifying, deleting, or executing any operations that would alter state or trigger side effects. The action is read-only data retrieval, placing it firmly in the Read category with low severity.
From the tool's definition Tool description states it 'Get[s] interaction network' and 'Shows how multiple proteins interact' — purely a retrieval/query operation. No modification, deletion, or execution of external processes is indicated.
Attacks that exploit this kind of access
Get interaction network between a list of proteins from STRING. Shows how multiple proteins interact with each other. It is categorised as a Read tool in the Gwas MCP Server, which means it retrieves data without modifying state.
Register the Gwas MCP server in PolicyLayer and add a rule for get_interaction_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 Gwas. Nothing to install.
get_interaction_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 get_interaction_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 get_interaction_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.
get_interaction_network is provided by the Gwas MCP server (muslus/gwas-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
