# Call Sites Find function call sites in a binary. ## When to use - Find all locations where a specific function is called - Identify callers of a function - Check if a function contains calls to other specific functions - Filter call sites based on caller criteria ## Instructions ### List function calls Using the VulHunt MCP tools, open the project (`open_project`) and run the following Lua query (`query_project`) to get all the function calls: ```lua local calls = project:calls_matching{ to = <target_call>, } local results = {} for _, call in ipairs(calls) do table.insert(results, { caller_address = tostring(call.caller_address), call_address = tostring(call.call_address), }) end return results ``` Possible values for `<target_call>`: - A string, e.g. `"system"` - An AddressValue - VulHunt APIs return addresses as AddressValue instances - Create one with `AddressValue.new(<hex_addr>)` (e.g., `<hex_addr> = 0x1234`) - A regex, e.g. `{matching = "<regex>", kind = "symbol"}` - A byte pattern, e.g. `{matching = "41544155", kind = "bytes"}` Returns a JSON object containing: - `caller_address` is the address of the function that makes the call - `call_address` is the address of the call site (specifically, the code block address where the call is made) #### List function calls with criteria To restrict the search to function calls where the caller also contains other calls, or the caller is a specific function, use: ```lua local calls = project:
