AI agents call get_dependents to retrieve information from Srclight without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries code structure (dependents/callers of a symbol) within a code indexing system. It retrieves and navigates data without creating, modifying, deleting, or executing code. The empty description is noted, which slightly lowers confidence, but the name and server purpose clearly indicate a read-only graph traversal operation.
From the tool's definition Tool name 'get_dependents' and server context ('search symbols, navigate call graphs, explore inheritance') indicate retrieval of dependency information without modification.
Documented attack patterns abuse exactly the kind of access get_dependents gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Srclight, and nothing reaches the server without passing your rules. This is the rule we recommend for get_dependents:
{
"version": "1",
"default": "deny",
"tools": {
"get_dependents": {}
}
}get_dependents is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_dependents. It is categorised as a Read tool in the Srclight MCP Server, which means it retrieves data without modifying state.
Register the Srclight MCP server in PolicyLayer and add a rule for get_dependents: 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 Srclight. Nothing to install.
get_dependents 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_dependents 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_dependents. 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_dependents is provided by the Srclight MCP server (srclight/srclight). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
