Walk the graph from a target symbol and group dependents by traversal depth. Depth-1 nodes will definitely break if the target
AI agents call impact to retrieve information from OpenCodeHub MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool reads and analyzes code dependency information to show which symbols depend on a target and at what depths. While the output could inform decisions about breaking changes, the tool itself only retrieves and organizes existing data from the indexed knowledge graph. It performs no side effects, code execution, data modification, or destruction.
From the tool's definition Tool description states 'Walk the graph from a target symbol and group dependents by traversal depth'—this is a graph traversal/query operation that retrieves and analyzes dependency relationships.
Attacks that exploit this kind of access
Walk the graph from a target symbol and group dependents by traversal depth. Depth-1 nodes will definitely break if the target. It is categorised as a Read tool in the OpenCodeHub MCP Server MCP Server, which means it retrieves data without modifying state.
Register the OpenCodeHub MCP Server MCP server in PolicyLayer and add a rule for impact: 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 OpenCodeHub MCP Server. Nothing to install.
impact 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 impact 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 impact. 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.
impact is provided by the OpenCodeHub MCP Server MCP server (theagenticguy/opencodehub). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
