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 | $0.01270 | $0.01270 |
| Opus 5 | $0.00635 | $0.00635 |
| Sonnet 5 | $0.00254 | $0.00254 |
| Haiku 4.5 | $0.00127 | $0.00127 |
Grade A, and why
xmcp CLAUDE.md scanned grade A with 1 finding 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.
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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
Regular HTTP requests (WebFetch, curl, requests) will NOT work for X articles because: How it starts
The opening of the file, as written. The whole thing — 175 lines — stays where its author put it; the contents beside it link to each section on GitHub.
XMCP - AI Agent Instructions
This file provides instructions for AI agents (Claude, GPT, etc.) using the XMCP.
CRITICAL: Article Fetching Requires Playwright
IMPORTANT: When fetching X/Twitter articles, you MUST use the get_article tool which uses Playwright.
Regular HTTP requests (WebFetch, curl, requests) will NOT work for X articles because:
- X articles require JavaScript to render
- Simple HTTP returns empty/incomplete content
- The
get_articletool uses Playwright to properly render the page
Correct Usage
# When user asks to read an X article:
1. Use get_article tool with the URL
2. DO NOT use WebFetch - it will fail
3. DO NOT try to scrape with requests - it will fail
Example
User: "Read this article: https://x.com/elonmusk/status/123456789"
CORRECT:
result = await get_article("https://x.com/elonmusk/status/123456789")
# Returns: {title, author, content, url}
WRONG:
# These will NOT work for X articles:
WebFetch("https://x.com/...") # Fails - needs JS
requests.get("https://x.com/...") # Fails - needs JS

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.
