Get all STRING interaction partners for your proteins. Returns a list of interacting proteins with confidence scores.
AI agents call get_interaction_partners 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 protein interaction data from the STRING database. It has no side effects, does not modify or delete data, does not execute arbitrary code or commands, and does not involve financial operations. The action is purely informational—fetching pre-existing interaction partner information and returning results. This is a straightforward read operation on a public bioinformatics database.
From the tool's definition Tool name 'get_interaction_partners' and description 'Get all STRING interaction partners for your proteins.
Attacks that exploit this kind of access
Get all STRING interaction partners for your proteins. Returns a list of interacting proteins 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_interaction_partners: 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_interaction_partners 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_partners 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_partners. 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_partners 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.
