Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00066 | $0.02166 |
| Opus 5.5 | $0.00026 | $0.00866 |
| Sonnet 5.5 | $0.00013 | $0.00433 |
| Haiku 4.5 | $0.00007 | $0.00217 |
Grade A, and why
phone 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 1mo 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
The opening of the file, as written. The whole thing — 177 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Phone & Voice
Two namespaces in one tool: /v1/phone/* for number intelligence + provisioning, /v1/voice/* for outbound AI calls. Pay per call in USDC. Any other path is refused before payment — the tool never reaches routes outside these two.
Phone numbers use E.164 format — + followed by country code and subscriber digits (US: +1 + 10 digits; UK: +44 + 10 digits; etc.). The examples below use <+E.164-number> as a placeholder — the LLM should substitute the actual number from the user's request, not copy the literal placeholder.
How to Call from MCP
const targetNumber = "<+E.164-number-from-user>" // e.g. user said "call my doctor at 415-..."
// Lookup carrier + line type
blockrun_phone({ path: "phone/lookup", body: { phoneNumber: targetNumber } })
// Buy a 30-day US number
blockrun_phone({ path: "phone/numbers/buy", body: { country: "US", areaCode: "415" } })
// Outbound AI call (requires `from` — see below)
const r = await blockrun_phone({ path: "voice/call", body: {
to: targetNumber,
from: "<+E.164-number-you-own>", // from phone/numbers/buy
task: "Confirm appointment for Friday at 3pm with Dr. Wong.",
voice: "june"
}})
// poll the result (free GET, no body)
blockrun_phone({ path: `voice/call/${r.call_id}` })

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.

phone is a skill published in the GitHub repository BlockRunAI/blockrun-mcp (392 stars, last pushed 5d ago), licensed MIT. It adds 66 tokens to every session and 2,166 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-08-30.
