What find_definition does on Ripple-MCP
AI agents call find_definition to retrieve information from Ripple-MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why find_definition is rated Low
This tool performs static analysis to locate and retrieve information about where symbols are defined in source code. It does not execute code, modify data, delete anything, or move data. It is a read-only query operation that retrieves semantic information from the codebase for impact analysis purposes. The low severity reflects that misuse would only expose code structure information, not cause harm.
From the tool's definition Tool description states it 'finds where a symbol is defined in a project' (function definitions, class definitions, module/class-level assignments).
Attacks that exploit this kind of access
The rule that runs find_definition safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Ripple-MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For find_definition, this is the rule to start with:
find_definition is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Ripple-MCP, apply this rule, and every find_definition call is checked against it from then on.
Questions about find_definition
找出符号在项目中的定义处:函数定义、类定义、模块级/类级赋值(常量、类属性)。. It is categorised as a Read tool in the Ripple-MCP MCP Server, which means it retrieves data without modifying state.
Register the Ripple MCP server in PolicyLayer and add a rule for find_definition: 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 Ripple-MCP. Nothing to install.
find_definition 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 find_definition 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 find_definition. 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.
find_definition is provided by the Ripple MCP server (0xyubo/ripple-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
