topolograph-bgp-analysis

topolograph-bgp-analysis is a skill for Claude Code from automateyournetwork/netclaw. It costs 96 tokens per session (1,511 once invoked), scanned A, original, Apache-2.0.

A read-only analysis tool for BGP, the routing system that exchanges network paths between networks. It examines the overall topology, routing sessions, learned routes, and virtual network placement collected by Topolograph.

In plain words
What is it for?
Use it to inspect BGP speakers and peerings, investigate learned routes, check VRF or VPN placement, and compare BGP data with the underlying IGP network graph.
Why use it?
It answers questions about the network-wide routing view instead of showing only one router's current table.

Token cost

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.

Security

Grade A, and why

topolograph-bgp-analysis 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 5d 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.

The opening of the file, as written. The whole thing — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Topolograph BGP Topology Analysis

pyats-routing, pyats-junos-routing and multivendor-device-query each read one live device's BGP table. This one reasons over BGP topology Topolograph has already collected via BMP — speakers, sessions, the route table across every reporting peer, VRF/VPN placement, and whether that BGP epoch actually corresponds to a stored IGP graph.

It answers "what does BGP believe the topology and route state are" — not "what is in this router's BGP table right now."

Remote, read-only

Same server as topolograph-igp-analysis (spec 119): topolograph-mcp is a remote HTTP MCP registered in config/openclaw.json, no local server, fronting your own Topolograph instance (TOPOLOGRAPH_MCP_URL, default https://topolograph.com/mcp), bearer TOPOLOGRAPH_API_TOKEN. No second credential — if the IGP skill already works, this one does too.

The server runs with TOPOLOGRAPH_MCP_READ_ONLY=true: mutation tools are absent from tools/list. None of the 14 BGP tools mutate anything.

Requires Topolograph >= 2.69 and a topolograph-mcp-server build that includes the BGP tool surface (upstream PR #1). Older instances will list these tools but every call 404s or returns empty — check TOOLS.md for the version note before assuming a live instance is broken.

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.
