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.

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 | $0.00054 | $0.02064 |
| Opus 5.5 | $0.00022 | $0.00826 |
| Sonnet 5.5 | $0.00011 | $0.00413 |
| Haiku 4.5 | $0.00005 | $0.00206 |
Grade A, and why
agentic-terminal 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 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.

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

The opening of the file, as written. The whole thing — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AT Directory
AT Directory is the agent commerce discovery surface for Bitcoin- and Tether-aligned payments. It indexes merchants that sell products, services, APIs, or content and accept Lightning, BOLT12, L402, or USDT (any chain), with trust attestations issued through Observer Protocol. It is not in the payment path — you discover merchants here and pay the merchant directly.
1. Connect — three paths, pick one
All three hit the same data and are anonymous + ungated (no credential to discover or transact).
A. Hosted MCP (recommended — lowest friction, no install). Point any MCP-compliant client at the hosted URL:
{ "mcpServers": { "at-directory": { "url": "https://mcp.agenticterminal.ai/mcp" } } }
B. Local MCP (npm). For air-gapped or offline-first setups:
npm install -g @agenticterminal/mcp-server # Node >= 20
at-directory-mcp # stdio MCP server
C. Plain REST (no MCP client needed). For agent runtimes that don't speak MCP (OpenClaw, custom Lightning-native agents) — just HTTP:
curl 'https://mcp.agenticterminal.ai/v1/merchants?rail=lightning&category=gift-cards'
curl 'https://mcp.agenticterminal.ai/v1/merchants/bitrefill'
curl 'https://mcp.agenticterminal.ai/v1/categories'
curl 'https://mcp.agenticterminal.ai/v1/rails'
curl -X POST 'https://mcp.agenticterminal.ai/v1/merchants/bitrefill/verify?rail=lightning'
REST endpoints return the same JSON as the matching MCP tool (search_merchants ↔ GET /v1/merchants, get_merchant ↔ GET /v1/merchants/{id}, etc.), including the agent_identity field.
The MCP tool surface (paths A/B): search_merchants, get_merchant, verify_payment_endpoint, list_categories, list_rails, whoami.
2. Two orthogonal axes — always read both
Each merchant carries two independent signals. They do not imply each other.
OP trust tier (how verified the merchant is):
- Tier 1 — self-attested; merchant claims the rails, unverified.
- Tier 2 — operator-verified; the AT operator transacted with the merchant and confirmed at least one claimed rail (v1.x: any OP-credentialed counterparty can attest, not just AT).
What ships with it
1 file 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.

agentic-terminal is a skill published in the GitHub repository observer-protocol/at-directory (0 stars, last pushed 18d ago), licensed MIT. It adds 54 tokens to every session and 2,064 once invoked, about $0.0002 per session on Opus 5.5. 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.
