Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.01681 | $0.01681 |
| Opus 5 | $0.00840 | $0.00840 |
| Sonnet 5 | $0.00336 | $0.00336 |
| Haiku 4.5 | $0.00168 | $0.00168 |
Grade A, and why
mcp-integration 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 10d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Overview
The MCP (Model Context Protocol) server provides 13 working tools via JSON-RPC 2.0 endpoint at /mcp.

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.

mcp-integration is a cursor rule published in the GitHub repository brendadeeznuts1111/betting-brain-v3 (8 stars, last pushed 11mo ago), licensed MIT. It adds 1,681 tokens to every session, about $0.0084 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

workers-patterns
Skim this on every task that touches workers, env, routes, or bindings.
typescript-imports
Golden rule: import each symbol from the module that defines it. A package index.ts may barrel only its own ./ modules — never another package.
git-workflow
Cloud Agents MUST run git add, git commit, and git push before ending their response when they have made code changes. Do not end your turn without pushing. ALWAYS use Pull Requests instead of pushing directly to main.
new-env-var-checklist
Checklist when adding any new env secret/variable — Turbo globalEnv, GitHub sync, workflow maps, Alchemy bindings. Prevents "secret synced but worker never gets it".

When the user has not yet personalized a copy of this monorepo, help them before building features.
