#ed25519

Gives AI agents verifiable, tamper-evident receipts for their actions — attest_action signs a cryptographic receipt for what the agent did (email sent, payment made, form filed), verify_receipt checks it offline, get_identity returns the agent's did:key. Sign locally, verify anywhere, zero backend.

Post-quantum, tamper-evident receipts for consequential agent actions. Four tools (mint_action_receipt, mint_receipt_for_record_change, verify_receipt, audit_my_agent_inventory) signed Ed25519 + ML-DSA-65 (FIPS 204), verifiable offline from the certificate alone. Defaults to PQ-required verify mode (defends against Ed25519-only downgrade by requiring at least one verified PQ leg). Apache-2.0.

Daily, Ed25519-signed security intelligence for AI-agent stacks: CVEs, supply-chain incidents and advisories (GHSA/CISA-KEV/OSV/NVD + national-CERT) assessed for MCP/LLM-proxy impact, cross-validated and signed. Paid via x402 ($0.10 USDC on Base); free sample, list_available, check_affected, get_since.

ANP2 MCP server — the full participation surface for the ANP2 agent network. 20 tools let an MCP-only agent register a profile, post and reply, declare capabilities, make knowledge claims, cast trust votes, and run the entire task economy (request → accept → submit result → verify → settle credit). The Ed25519 key is generated and held locally; the server signs every event and mines any required proof-of-work, so the agent never handles keys. Read tools: anp2_query, anp2_get_capabilities, anp2_get_agents, anp2_get_rooms, anp2_get_stats, anp2_get_task, anp2_get_credit. Write tools: anp2_register, anp2_post, anp2_reply, anp2_declare_capability, anp2_knowledge_claim, anp2_trust_vote, anp2_beat, anp2_beacon, anp2_request_task, anp2_accept_task, anp2_submit_result, anp2_verify_task, anp2_release_payment. Install: pip install anp2-mcp-server

AI agent gateway for calling any API — discover tools, manage credentials, execute tasks with Ed25519 identity and OPA policy enforcement.

Sovereign cryptographic oracle — 131 Ed25519-signed endpoints across crypto prices, FX, metals, stablecoins, economic indicators, commodities, gas oracles, volatility/sentiment/stress/contagion indices, marine, weather, DeFi yield, and COT positioning. Pay-per-query via x402 (USDC on Base). No API keys.

HemmaBo is the host-owned trust layer for vacation rentals: every host runs 0%-commission direct bookings on their own domain, with host-signed, agent-verifiable offers that AI agents can discover, verify, and book directly. HemmaBo + VRP, 15 tools: an agent discovers a host's own domain, verifies a host-domain signed (VRP · Ed25519/JWKS) stay offer with live availability and exact price, and routes to the direct booking URL on the host's own domain.

Cryptographic audit trail for AI agents via Model Context Protocol. Every AI decision signed Ed25519, hash-chained, tamper-proof. AISS-1.0 compliant. Post-quantum ready. Compliance-ready for SEC, FINRA, GDPR, HIPAA.

HemmaBo verifies and books host-owned vacation rental domains. Use it when the user wants a direct, host-domain verified stay offer. HemmaBo + VRP, 15 tools, host-domain signed verified stay offers. Offers are cryptographically signed by the host domain and verified against that domain's published Ed25519 JWKS. Supports UCP discovery, ACP checkout, and AP2 (Agent Payments Protocol) Cart Mandate verification. Not an OTA. Not a marketplace.

Cryptographic accountability for AI agents. Ed25519-signed receipts for every MCP tool call — constraints, chains, AI judgment, invoicing, local dashboard.

Cryptographic identity, policy enforcement, trust scoring, and tamper-proof audit trails for AI agents. Register agents, track signed events, check policies, and get trust profiles — all from Claude, Cursor, or Windsurf. OWASP Agentic Top 10 compliant.

Cryptographic runtime governance for AI agents. 20 tools. Sealed policy artifacts, continuous measurement, tamper-evident proof. Ed25519 + SHA-256.

Certification authority for AI agents. Register, take adversarial exams, earn cryptographically signed credentials (Ed25519). Get paid to examine other agents. 20,000 free credits on registration — no payment needed to start.

Cryptographically signed market status (OPEN/CLOSED/HALTED/UNKNOWN) for 28 global exchanges with Ed25519-signed receipts. Designed for AI agents and automated trading systems. Fail-closed: UNKNOWN always means CLOSED. 5 MCP tools. x402 micropayments on Base mainnet.
