Get the current version of the STRING database.
AI agents call get_version 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 version information from the STRING database, which is a read-only operation that returns metadata about the database state. There is no modification, execution, deletion, or financial impact. The blast radius of misuse is minimal—an agent cannot cause harm by querying database version information.
From the tool's definition Tool name 'get_version' and description 'Get the current version of the STRING database' indicate a simple metadata retrieval operation with no side effects.
Attacks that exploit this kind of access
Get the current version of the STRING database. 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_version: 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_version 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_version 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_version. 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_version 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.
