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 | $0.01301 | $0.01301 |
| Opus 5.5 | $0.00520 | $0.00520 |
| Sonnet 5.5 | $0.00260 | $0.00260 |
| Haiku 4.5 | $0.00130 | $0.00130 |
Grade A, and why
lightning-enable-mcp CLAUDE.md 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 22d 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.

CLAUDE.md — Lightning Enable MCP
Project Overview
Part of Lightning Enable — infrastructure for agent commerce over Lightning.
Open-source (MIT) MCP server for AI agent Lightning payments. See the main repo at F:\lightning-enable for full context.
Publishing: Bump the version in ALL SIX files in the SAME commit, then push to main:
dotnet/src/LightningEnable.Mcp/LightningEnable.Mcp.csproj—<Version>python/lightning-enable-mcp/pyproject.toml—versionserver.json—.version, both.packages[].version(nuget + pypi), and the Docker image pin in.packages[2].identifier(docker.io/refinedelement/lightning-enable-mcp:<version>)mcpb/manifest.json—.versionmcpb/pyproject.toml—versionand thelightning-enable-mcp==<version>dependency pindotnet/src/LightningEnable.Mcp/Services/UserAgent.cs—FallbackVersion(the last-resort User-Agent version, used only if the assembly has no version).UserAgentTestsfails the .NET suite on drift;publish-mcp.ymldoes not check it.
publish-mcp.yml's verify-versions job checks the first five and fails the whole publish on any drift (2.0.3 was caught this way).
server.json is committed source-of-truth for the MCP Registry entry — it is NOT rewritten at publish time. publish-mcp.yml verifies it matches the release version and fails the registry publish on any drift, so a partial bump (e.g. csproj/pyproject bumped but server.json left stale) is caught before it strands registry.modelcontextprotocol.io on an old version. server.json's description must be ≤100 chars (also enforced by MCP Registry and CI validation).
Approval channel (out-of-band confirmation)
Over-threshold payments require a human-relayed confirmation code. The code is the operator's, never the model's — it must never appear in a tool result on any channel, and a payment is never approved because its notification could not be delivered (a delivery failure REFUSES the payment and withdraws the minted code).
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.

lightning-enable-mcp CLAUDE.md is an instructions file published in the GitHub repository refined-element/lightning-enable-mcp (9 stars, last pushed 11d ago), licensed MIT. It adds 1,301 tokens to every session, about $0.0052 per session on Opus 5.5. 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 2026-08-31.
