Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00020 | $0.00916 |
| Opus 5 | $0.00010 | $0.00458 |
| Sonnet 5 | $0.00004 | $0.00183 |
| Haiku 4.5 | $0.00002 | $0.00092 |
Grade A, and why
gns3-link-management scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

GNS3 Link Management
Create and manage links between node interfaces in GNS3 projects. Build network topologies by connecting devices and isolate nodes for testing.
When to Use
- Connecting two network devices together
- Building out a network topology
- Viewing existing connections in a lab
- Removing links between devices
- Isolating a node without deleting its links
- Re-enabling links after isolation testing
MCP Server
- Command:
python3 -u mcp-servers/gns3-mcp-server/gns3_mcp_server.py(stdio transport) - Requires:
GNS3_URL,GNS3_USER,GNS3_PASSWORDenvironment variables
Available Tools
| Tool | Parameters | What It Does |
|---|---|---|
gns3_list_links |
project_id | List all links with connected nodes and interfaces |
gns3_create_link |
project_id, node1, port1, node2, port2 | Create a link between two interfaces |
gns3_delete_link |
project_id, link_id | Delete a link |
gns3_isolate_node |
project_id, node_id, isolate | Disable/enable all links to a node |
Interface Name Formats
The tools support multiple interface naming conventions:
| Format | Example | Adapter | Port |
|---|---|---|---|
| eth# | eth0, eth1 | 0 | 0, 1 |
| Ethernet# | Ethernet0 | 0 | 0 |
| Gi#/# | Gi0/0, Gi0/1 | 0 | 0, 1 |
| GigabitEthernet#/# | GigabitEthernet0/0 | 0 | 0 |
| Fa#/# | Fa0/0, Fa0/1 | 0 | 0, 1 |
| e# | e0, e1 | 0 | 0, 1 |
| port# | port0, port1 | 0 | 0, 1 |
| #/# | 0/0, 0/1 | 0 | 0, 1 |
Workflow Examples
Build a Topology
# Connect router to switch
"Connect router1 Gi0/0 to switch1 eth0 in routing-test"
# Connect switch to another router
"Connect switch1 eth1 to router2 Gi0/0 in routing-test"
# Connect hosts to switch
"Connect host1 eth0 to switch1 eth2 in routing-test"
View Topology
# List all connections
"List all links in routing-test"
Isolate for Testing
# Isolate a node (disable all its links)
"Isolate router1 in routing-test"
# Test behavior with router1 disconnected...
# Re-enable links
"Unisolate router1 in routing-test"
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

gns3-link-management is a skill published in the GitHub repository automateyournetwork/netclaw (657 stars, last pushed 6d ago), licensed Apache-2.0. It adds 20 tokens to every session and 916 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
