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 | $0.00061 | $0.01937 |
| Opus 5 | $0.00030 | $0.00968 |
| Sonnet 5 | $0.00012 | $0.00387 |
| Haiku 4.5 | $0.00006 | $0.00194 |
Grade A, and why
mcp-builder 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 11d 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.

No licence file
A repository with no LICENSE is all rights reserved by default, so the body is not copied here. The metadata, the measurements and the link are.
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-builder is a skill published in the GitHub repository glassBead-tc/audius-mcp-atris (5 stars, last pushed 1mo ago), with no licence file. It adds 61 tokens to every session and 1,937 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other skills, from other repositories
utcp-cli
Call external APIs, MCP servers, and CLI tools by writing TypeScript code that runs in a sandbox — without MCP. Use when the user wants the agent to use a tool/API/integration (e.g. "search Open Library", "read my Notion", "call this REST API") in an environment that has a shell but no MCP config and no settable…
workers-best-practices
(APPLICATION CODE ONLY) Reviews and authors Cloudflare Workers code against production best practices. Use ONLY when writing or reviewing Worker code, configuring wrangler.jsonc, or checking for anti-patterns. Do NOT use for general Cloudflare product discovery (use cloudflare instead) or CLI management (use wrangler…
hono
Hono framework best practices. Use when building, reviewing, or debugging Hono applications, especially on Cloudflare Workers. Covers routing, middleware, context (c), and RPC patterns. Do NOT trigger for generic 'build a server' requests unless Hono or Cloudflare Workers is explicitly requested.
nodejs
Node.js core runtime standards. Use when working with native Node.js APIs like streams, buffers, childprocess, workerthreads, filesystem, or event loop tuning. Do NOT trigger for generic 'build a server' requests unless the platform/language is explicitly specified.
trpc
Skill "trpc" from neverinfamous/memory-journal-mcp, covering trpc guidelines, 1. routers and procedures, 2. context and middleware and 3. client integration.
zod
Zod schema validation standards. Use when defining schemas, parsing user input, transforming data, or integrating type-safe boundaries in API endpoints and configurations. SECURITY: Zod schemas are your primary security boundary. Ensure they are strict and handle all edge cases.
