lightning-mcp-server

lightning-mcp-server is a skill for Claude Code from lightninglabs/lightning-agent-tools. It costs 71 tokens per session (2,139 once invoked), scanned A, original, no licence file.

A guide for building an MCP server that connects AI assistants to lnd Lightning nodes. MCP is a standard way for an AI assistant to call external tools; this connection uses encrypted WebSocket tunnels and pairing phrases instead of direct network access or TLS certificates.

In plain words
What is it for?
Checking node state, channels, payments, invoices, peers, and on-chain data through 18 read-only tools, and configuring Lightning Node Connect sessions.
Why use it?
It lets an assistant query a Lightning node without exposing the node directly to the network. The connection is read-only by default, which limits accidental changes.

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

lightning-mcp-server 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 6d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/configure.sh, scripts/install.sh, scripts/setup-claude-config.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Changes

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.
