Class McpSnmpEncodeBER

java.lang.Object
org.snmp4j.mcp.tool.snmp.ber.McpSnmpEncodeBER
All Implemented Interfaces:
McpTool
public class McpSnmpEncodeBER extends Object implements McpTool
MCP tool that encodes a BER node tree — expressed in the same JSON format that snmp_message_ber emits — back into raw message bytes, with optional fault injection, declarative mutations and computed permutations. The hex output is designed to be fed to snmp_send_raw.

The tool composes BerJsonEncoder (node tree → bytes, including invalid encodings) with BerMutations (JSON-Pointer edits and permutation sweeps), enabling an MCP client to systematically fuzz an SNMP agent: corrupt tags, forge lengths, truncate fields, flip bits, and sweep values/ranges across one or more elements.

Since:
0.1.0
