What is eventbrite-mcp CLAUDE.md?

Repository-specific instructions for an Eventbrite MCP server, a service that lets an AI agent work with Eventbrite data and events.

Use them when developing or debugging this repository's Eventbrite search, event lookup, API fallback, and CSRF-protected requests.

They keep implementation details in one place, including which API route to use, how authentication works, and when to use the browser bridge.

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	$0.00640	$0.00640
Opus 5	$0.00320	$0.00320
Sonnet 5	$0.00128	$0.00128
Haiku 4.5	$0.00064	$0.00064

Security

Grade A, and why

eventbrite-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 7d 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 it actually says

eventbrite-mcp

MCP server for Eventbrite. Facts specific to THIS repo (fleet-wide conventions live in ~/.claude/CLAUDE.md and the mcp-fleet-builder skill — don't restate them here):

Two surfaces, one preferred route. src/client.ts = documented API (eventbriteapi.com/v3, bearer EVENTBRITE_TOKEN, deferred config error). The documented host also serves the consumer discovery API: POST /destination/search/ and GET /events/?event_ids= both answer 200 to a plain bearer token (private OR public) — no WAF, no CSRF, no cookies (verified live 2026-07-30). src/discovery.ts therefore calls the API FIRST and falls back to src/transport-fetchproxy.ts (the bridge, port 37149) only when there is no token or the API refuses. Browse pages (/d/<slug>/events/) are likewise reachable by a plain server-side GET.
Search POST needs CSRF: X-CSRFToken = the csrftoken cookie (read via the bridge's read_cookies capability) + X-Requested-With: XMLHttpRequest. GETs are exempt. On a CSRF Failed 401, re-read the cookie and retry once (already implemented in DiscoveryClient.search).
Cookie scope must stay in the FIRST pairing declaration (createBootstrapOpts in transport-fetchproxy.ts) — Transporter cannot widen scope after the initial pair approval; changing declared scopes forces a full re-pair (profile remove/re-add on the fpx CLI side).
Place ids: searches take Whosonfirst-style ids, resolved by grepping "placeId" from the SSR bytes of /d/<slug>/events/ (a direct fetch — no bridge). There is no API endpoint for this: /destination/places/, /places/ and /destination/autocomplete/ all 404. Never guess ids; never call the site's Google Places autocomplete. Free-text locations become candidate slugs via slugCandidates; a bare city yields none by design.
Never call /destination/search/log_requests/ or /log_engagement/ (site telemetry).
All request/response shapes are pinned in docs/EVENTBRITE-API.md with their verification status — keep that file's status notes truthful when endpoints change, and re-capture before coding new ones.
registerDiscoveryTools takes the fetchproxy bridge or null. With null it registers the API-route discovery tools but skips eb_healthcheck, which diagnoses the bridge and has nothing to report without one.
Version lives in src/version.ts alone (single x-release-please-version marker); index.ts imports it.

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.
