SNMP Trap Receiver Skill

Receive and query SNMP traps from network devices via UDP.

Skill ID

snmptrap-receiver

Description

This skill enables NetClaw to receive SNMP traps from network devices (routers, switches, firewalls) and query the collected data. It supports SNMPv1, SNMPv2c, and SNMPv3 trap formats.

When to Use

Monitoring network device events (link up/down, authentication failures)
Investigating incidents by querying historical trap data
Aggregating traps from multiple network devices
Filtering traps by type, source, or SNMP version
Analyzing trap patterns across the network

Required MCP Server

snmptrap-mcp

Available Tools

Tool	Purpose
`snmptrap_start_receiver`	Start listening for SNMP traps
`snmptrap_stop_receiver`	Stop the receiver
`snmptrap_get_status`	Check receiver status and statistics
`snmptrap_query`	Search traps with filters
`snmptrap_get_trap`	Get full details of a specific trap
`snmptrap_get_counts`	Get trap counts by type and source

Example Workflows

Start Monitoring

1. Use snmptrap_start_receiver with port 10162
2. Configure network devices to send traps to this port
3. Use snmptrap_get_status to verify traps are being received

Investigate Link Issues

1. Use snmptrap_query with trap_oid_prefix "1.3.6.1.6.3.1.1.5" for standard traps
2. Filter by source_ip to focus on specific device
3. Use snmptrap_get_trap for full variable binding details

Daily Summary

1. Use snmptrap_get_counts to see trap distribution
2. Focus on linkDown, authenticationFailure counts
3. Query high-frequency trap sources for details

Sample Prompts

"Start the SNMP trap receiver on port 10162"
"Show me all linkDown traps from the last hour"
"How many traps have we received by type?"
"Find all SNMP traps from 192.168.1.1"
"What's the trap receiver status?"
"Query SNMPv3 traps received today"

Configuration

The snmptrap-mcp server is configured via environment variables:

SNMPTRAP_PORT: UDP listening port (default: 162)
SNMPTRAP_BIND_ADDRESS: Bind address (default: 0.0.0.0)
SNMPTRAP_RETENTION_HOURS: Trap retention (default: 24)
SNMPTRAP_RATE_LIMIT: Max traps/second (default: 1000)
SNMPTRAP_DEDUP_WINDOW: Dedup window in seconds (default: 5)

Limitations

In-memory storage only (data lost on restart)
SNMPv3 requires USM user configuration for full parsing
Single instance per port
No MIB compilation (OIDs shown numerically)
UDP only (no TCP/TLS support)
