Agentic Terminal Directory

observer-protocol/at-directory

A discovery layer for merchants that accept Lightning, BOLT12, L402, or USDT, with trust attestations from Observer Protocol. Six tools let agents search merchants by category or rail, retrieve payment endpoints, and verify credentials before transacting. The server doesn't touch payments, it routes agents to direct merchant integrations. Merchants are tiered: self-attested, operator-verified, or chain-anchored. You can run it hosted at mcp.agenticterminal.ai or install locally. Reads are ungated, writes need an Observer Protocol credential. Reach for this when your agent needs to find and vet payment-enabled services without hardcoding a provider list.

Install

From registry metadata

$ npx add-mcp https://mcp.agenticterminal.ai/mcp --name directory

Run in your terminal. add-mcp asks which agents to add it to (Claude Code, Codex, Cursor and more). Add -g to install it for every project.

Review the command, arguments and environment values before installing. MCP servers run with your local permissions.

Other ways

Claude Code

$ claude mcp add --transport http directory https://mcp.agenticterminal.ai/mcp

Run in your terminal. Add --scope user to make it available in every project.

Readme

AT Directory

Where agents discover OP-verified merchants on the rails Bitcoin and Tether actually use.

AT Directory 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 the verified, agent-callable layer on top of the fragmented agent-payment landscape. It is not in the payment path — agents discover here and pay merchants directly.

MCP server (primary product) — @agenticterminal/mcp-server, hosted at mcp.agenticterminal.ai.
Web directory — agenticterminal.ai, same data rendered for humans.
SKILL.md — teaches an agent how to query and complete payment handoff.

Status

Pre-v1, active build. Target: week of 2026-05-18 for a live Tether-meeting demo. v1 ships Tiers 1–2.

Use it from an agent

// Hosted (recommended, no install)
{ "mcpServers": { "at-directory": { "url": "https://mcp.agenticterminal.ai/mcp" } } }

npm install -g @agenticterminal/mcp-server   # local alternative
