Retrieve protein-protein interaction network for given proteins. Returns network edges with confidence scores.
AI agents call get_network to retrieve information from STRING 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 data from the STRING protein-protein interaction database without creating, modifying, deleting, or executing any operations. It is a straightforward read operation that returns existing network data. The lack of side effects, irreversible actions, code execution, or financial implications places it clearly in the Read category with low severity.
From the tool's definition Tool description states 'Retrieve protein-protein interaction network' and 'Returns network edges with confidence scores.' The verb 'Retrieve' and 'Returns' indicate data retrieval with no modification or execution of operations.
Attacks that exploit this kind of access
Retrieve protein-protein interaction network for given proteins. Returns network edges with confidence scores. It is categorised as a Read tool in the STRING MCP Server MCP Server, which means it retrieves data without modifying state.
Register the STRING MCP Server MCP server in PolicyLayer and add a rule for get_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 STRING MCP Server. Nothing to install.
get_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_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_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_network is provided by the STRING MCP Server MCP server (munch-group/string-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
