nostr-merchant

The AI that runs your NOSTR business. A local-first Python agent that holds the whole merchant toolkit — it checks its Lightning wallet, publishes notes and listings, runs a Shopstr storefront, answers encrypted DMs, triages its NOSTR inbox to draft and post replies, and pays for paywalled MCP tools over NWC — all under sats budget caps it can't exceed. Built on five MCP servers (nwc-mcp, nostr-ops-mcp, marketplace-mcp, albyhub-admin-mcp, paywall-mcp) — 37 tools the agent picks from.

Ollama-first, API-pluggable. Built on pydantic-ai — no LangChain. MIT.

v0.3 — engagement inbox. Seven CLI commands. nostr-merchant inbox triages replies/mentions on your recent posts and drafts responses in your voice (read-only, language-matched); inbox --post walks each draft (approve / edit / skip), confirms, and publishes the approved ones as NIP-10 replies. The agent layer enforces a budget-and-audit safety pipeline on top of every MCP server's own safety stack; the self-paying-for-tools loop holds end to end given a working LLM backend (Ollama / Anthropic / OpenAI). (Renamed from llmops-agent in v0.2.)

Install

pipx install nostr-merchant          # recommended: isolated CLI
# or:  uvx --from nostr-merchant nostr-merchant --help
# or:  pip install nostr-merchant

The five MCP servers it drives are launched on demand via npx -y — no separate install. You need Python 3.11+, an NWC-compatible wallet (e.g. Alby Hub), and an LLM backend (see Usage).

Status

Usage

# from this directory, with uv-installed venv
uv run nostr-merchant --help
uv run nostr-merchant version
uv run nostr-merchant budget                # snapshot, no LLM needed
uv run nostr-merchant config-print          # effective config, secrets masked
uv run nostr-merchant doctor                # ping each configured MCP server
uv run nostr-merchant ask "What's my Lightning wallet balance?"   # the main demo loop
uv run nostr-merchant audit --tail 20       # recent audit entries

Or run the whole sequence with the bundled script: ./smoke.sh (full run — the ask is read-only, so it can never move sats) or ./smoke.sh --no-ask (skip the LLM call entirely).

ask requires a working LLM backend, set via NOSTR_MERCHANT_MODEL:

• anthropic:claude-haiku-4-5-20251001 (or any Anthropic/OpenAI model) — fast, reliable tool-calling. Set ANTHROPIC_API_KEY (or OPENAI_API_KEY) in ~/.nostr-merchant/.env. Recommended for most setups.
• ollama:<model> — fully local, no KYC, no phone-home (the sovereignty default). Needs Ollama at localhost:11434. Reality check: a 37-tool agent loop wants real hardware — a small model on a CPU-only box is too slow to be practical. Run Ollama on a GPU, or use a hosted model and keep your wallet + keys local (the trust boundary that actually matters).

Provider creds in ~/.nostr-merchant/.env are loaded automatically — no need to export them.

Dev loop

uv sync                 # install deps + dev deps into .venv
uv run ruff check       # lint
uv run mypy             # type check
uv run pytest           # tests
