⚡ NostrPulse (nostrpulse-mcp)

Autonomous Micropayments (Cashu eCash & NIP-61) and Guardrails for AI Agents

The Decentralized Stripe & Radar for Autonomous AI Agents via Nostr, Cashu eCash (NIP-61), and Model Context Protocol (MCP).

NostrPulse is an open-source payment and sovereign trust layer for autonomous AI agents, built on top of the Freedom Tech Stack (Nostr + Bitcoin Lightning + Cashu Chaumian eCash + Model Context Protocol). It provides Stripe-like settlement (M2M micro-payments via NIP-61 NutZaps) and Stripe Radar-grade anti-Sybil protection (Web-of-Trust graph distance + verifiable Economic Stake) for Cursor, Claude Desktop, and autonomous LLMs.

🤖 MCP Server for AI Agents (Stripe for AI)

NostrPulse natively exports an industry-standard Model Context Protocol (MCP) server over Stdio JSON-RPC. Any AI client (Claude Desktop, Cursor, Windsurf, LangChain, Vercel AI SDK) can instantly tap into decentralized reputation, machine-to-machine micropayments, and distributed compute without API keys or custodial accounts.

1. Zero-Code Quickstart (Cursor & Claude Desktop)

Paste this configuration directly into your claude_desktop_config.json or .cursor/mcp.json:

{

"mcpServers": { "nostrpulse": { "command": "npx", "args": ["-y", "nostrpulse-mcp"] } } }

• Claude Desktop Config File Locations:
• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Cursor IDE: Save to .cursor/mcp.json in your project root, or add under *Cursor Settings > Features > MCP*.

2. Interactive Testing via MCP Inspector

Verify tools, examine schemas, and test prompts in the browser via the official Model Context Protocol Inspector:

npx @modelcontextprotocol/inspector npx -y nostrpulse-mcp

3. Core MCP Tools Lookup Table

4. Profiles for Small Language Models (SLMs: 500M – 1.5B)

For edge devices, local SLMs (e.g., Qwen 2.5 0.5B/1.5B via Ollama), or cost-sensitive agent loops, NostrPulse supports context-optimized profiles that reduce prompt overhead from ~2,200 tokens down to ~380 tokens:

# Launch with minimal profile (3 core tools: check_trust_score, pay_cashu_nutzap, get_spending_guardrails)

npx -y nostrpulse-mcp --profile=minimal

Or via environment variable

NOSTRPULSE_PROFILE=minimal npx -y nostrpulse-mcp

5. Autonomous Agent-to-Agent (A2A) Collaborative Mesh

NostrPulse includes a reference implementation for autonomous agent-to-agent decentralized negotiation and micro-commerce (scripts/test-mesh-agent.ts):

[ Agent A: Requester / Buyer ]                   [ Agent B: Worker / Seller ]

│ │ ├──► 1. Dispatch NIP-90 Job ('zap-analytics') ──►│ │ │ │ 2. Audit Requester WoT Anti-Sybil Score ◄───┤ (Requires Trust Score > 40) │ (check_trust_score) │ │ │ │◄── 3. Acknowledge & Deliver Computation ───────┤ │ │ ├──► 4. Inspect Budget Guardrails (assert 24h) │ │ │ ├──► 5. Settle Cashu NutZap (Adaptive Fallback) ─►│

• Zero-Cloud Local Inference: Run the showcase locally using Ollama (qwen2.5-coder:1.5b) without cloud API keys:

  npm exec tsx scripts/test-mesh-agent.ts --ollama

• Adaptive Spending Fallback: If a requested micro-payment exceeds the rolling 24-hour spending limit, the agent automatically adapts down to the remaining safe allowance to settle minimum fees without crashing or overspending.

🌐 The Problem & The Freedom Solution

Open agentic systems and decentralized protocols eliminate platform lock-in, but introduce two critical vulnerabilities:

1. Agent Impersonation & Sybil Floods: Cryptographic keypairs (npub) cost $0 to generate, making spam bots, clone accounts, and wash-trading rampant.
2. Payment Fragility & KYC Lockouts: Legacy banking rails (Stripe/PayPal) freeze autonomous agents. Synchronous Lightning Zaps (NIP-57) fail when receiver nodes are offline or lack inbound liquidity channels.

Paradigm Shift
