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 | $0.01871 | $0.01871 |
| Opus 5 | $0.00936 | $0.00936 |
| Sonnet 5 | $0.00374 | $0.00374 |
| Haiku 4.5 | $0.00187 | $0.00187 |
Grade A, and why
ultrabrain-mcp AGENTS.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.
How it starts

Runtime Shape
This repository is a TypeScript MCP stdio server. Source lives in src/, build
output lives in dist/, and the runtime entry point is dist/index.js.
The public MCP surface is LCV-branded. Tool names must use the ultrabrain_*
prefix. Do not add legacy third-party tool names as public aliases.
Mandatory Gates
npm test
npm run biome
npm run format:public:check
npm pack --dry-run
For local MCP runtime checks after installation:
ultrabrain-mcp
Do not run the server directly in a blocking shell unless it is attached to an MCP client or a smoke harness; stdio MCP servers wait for protocol input.
Release and Publishing
- Do not publish from the workstation.
auto-tag.ymlcreates the padded display tag (v00.00.00) frompackage.json.- The first public release is
v01.00.00from npm package version1.0.0. publish.ymlpublishes to npmjs.com and GitHub Packages, then creates the GitHub Release.- GitHub Pages serves
site/through the custom domainultrabrain-mcp.lcv.dev. - Third-party actions must remain pinned to reviewed immutable commit SHAs.
Security
- Do not commit
node_modules/,dist/,.env, API keys, MCP bearer tokens, or local host configs. - This package is local-first and must not add external LLM/API calls without an explicit design decision.
- Keep development checkout and global installation separate. Do not use
npm linkor create a junction fromC:\npm-global\node_modules\@lcv-ideas-software\ultrabrain-mcpto this workspace checkout.
Workspace Policy
Follow the workspace-root AGENTS.md directives of the private workspace that
hosts this checkout (not versioned in this public repository). In
particular: no self-review in cross-review gates, ultrabrain plus
cross-review before substantive closure, and main as the deployment branch.
Trocas mecanicas de Actions dispensam cross-review; mudancas substantivas
continuam sujeitas ao gate. Commit & Sync ocorre somente depois da auditoria
final, quando solicitado.
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.
