What is nightlife-mcp CLAUDE.md?

Technical instructions for a nightlife event-discovery MCP server. MCP is a standard that lets AI assistants call tools; this server searches events, venues, and performers using a shared read-only database.

Use it to find nightlife events by city, date, genre, or area; view tonight's events; inspect venues and performers; and run the service in development or production.

It explains how to run the server locally or over HTTP and documents the available searches and detail lookups.

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.

Model	Per session	Once invoked
Fable 5.1	$0.06334	$0.06334
Opus 5.5	$0.02534	$0.02534
Sonnet 5.5	$0.01267	$0.01267
Haiku 4.5	$0.00633	$0.00633

Measured 9d ago against content hash 363db999a006, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

nightlife-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 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.

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.
