HemmaBo-se/hemmabo-mcp-server
Host-owned, agent-native direct booking for vacation rentals: agents discover a host's own domain, verify a host-domain signed (VRP · Ed25519/JWKS) stay offer, read live availability and pricing, and book directly at 0% commission. Live endpoint: https://www.hemmabo.com/mcp
luisgf/infrabroker
SSH & Kubernetes access broker where the model never touches a credential: a separate signer mints per-operation ephemeral SSH certificates and bound ServiceAccount tokens, with a per-command allow/deny/approval firewall (POSIX-sh AST), dry-run, human-in-the-loop approvals, session recording and an Ed25519-chained audit log. Self-hosted Go binaries, GPLv3.
tomjwxf/scopeblind-gateway
Security gateway that wraps any MCP server with per-tool policies, approval gates, and optional Ed25519-signed receipts. Shadow mode logs every tool call; enforce mode blocks, rate-limits, or requires approval.
Kzino/vorim-mcp-server
AI agent identity, trust, and audit trail infrastructure. 17 MCP tools: register agents with Ed25519 keypairs, check permissions (sub-5ms), emit tamper-evident audit events, verify trust scores (0-100), delegate credentials, and manage ephemeral agents. IETF Internet-Draft filed (draft-vorim-vaip-00). Works with LangChain, OpenAI, CrewAI, Stripe ACP, and 4 more frameworks. `npx @vorim/mcp-server`.
emiliaprotocol/emilia-protocol
Human sign-off + trust receipts for AI agents: requires a named human's approval before an irreversible action (payment release, record change, deploy), then mints an offline-verifiable Ed25519 Trust Receipt. Also exposes trust profiles, receipt verification, disputes, and delegation. Apache-2.0; policy engine formally verified. Install: `npx -y @emilia-protocol/mcp-server`.
ScopeBlind/verify-mcp
Offline verification of signed artifacts -- receipts, manifests, audit bundles. Ed25519 + JCS. No accounts, no API calls. Apache-2.0.
lacs-project/sysknife
Security-hardened MCP server for Linux system administration via 189 typed actions instead of shell strings, with an Ed25519-signed hash-chain audit log, one-time TTL approval receipts, and automatic rollback. Works with Claude Code, Cursor, and Codex CLI.
Declade/lucairn-sdks
Privacy-preserving AI gateway. Sanitises PII (German + English; Microsoft Presidio + custom recognisers) before prompts reach Anthropic / OpenAI / your LLM, then emits a signed cryptographic certificate per call (Ed25519 + RFC 3161 timestamp + Sigstore Rekor anchoring). EU GDPR + AI Act ready. Free tier 500 calls/month, BYOK. Install: `npx -y @lucairn/mcp-server`. Docs: https://lucairn.eu/develope
Proofpane/releases
Governance proxy for MCP: pair once and route your MCP servers through policy gates (allow / deny / human-in-the-loop approval), DLP redaction before the model, and cost caps, with every tool call recorded to a hash-chained audit log exportable as an Ed25519-signed, offline-verifiable evidence pack. Single-file binary daemon (macOS / Linux / Windows); downloads and install docs in the linked repo.
degenlegion-com/waxseal-sdk
On-chain Ed25519 identity for AI agents — verify seals by fingerprint, validate document signatures, and gate irreversible actions behind human-signed approval tokens. Hosted at `api.waxseal.id/mcp`; local install (`npx @waxseal/mcp`) for signing.
aeoess/mingle-mcp
