Earth memory MCP server that gives AI agents signed geospatial facts and cite-able receipts for place-based questions. Covers elevation, land cover, surface water, vegetation, and built-up context. Public endpoint at `https://emem.dev/mcp`.
Kentucky-ai/opentakeoff
Construction plan takeoff on stdio — load a plan PDF, read the title block, adopt the drawing scale (never applied silently), one-click trace rooms, and export real-world quantities (square footage, linear feet, counts) with provenance receipts. Install via NPM: `npx -y opentakeoff-mcp`
Swarmwage/swarmwage
Open MCP-native agent hire protocol — discovery + hiring + reputation layer above x402 payment rails. Find specialized agents, hire them with one function call, settle in USDC on Base. Sub-second sync, on-chain receipts via EIP-3009, zero protocol fee. Live mainnet 2026-05-10.
sint-ai/sint-protocol
Security-first MCP governance proxy (`sint-mcp`) with capability tokens, T0-T3 approval tiers, fail-closed execution, and tamper-evident audit receipts. Includes a separate `sint-scan` CLI for preflight MCP tool-risk audits.
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.
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`.
michaelellis003/paperboy
Send research papers from Claude to a Kindle or Kobo, with Zotero as the source of truth. Searches arXiv and OpenAlex, recommends related work via the Semantic Scholar citation graph, queues papers in a Zotero collection, and delivers the PDFs by email or Dropbox. Receipts report file sizes and name anything that could not be sent.
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.
Jott2121/agent-gate
Lets an AI agent gate its own work before claiming "done": a fail-closed ship checklist (`verify_gate` counts a check satisfied only if explicitly proven), required independent refute-first review, and an append-only sha256-chained receipts ledger that makes any edit to past receipts detectable. `pip install mcp-agent-gate`.
HarperZ9/telos
Local-first Project Telos MCP tool line for inspectable AI work: source intake, workspace context, routing ledgers, action receipts, and MATCH / DRIFT / UNVERIFIABLE verification packets across 5 stdio servers.
trustscoreagent/trustscoreagent
Check the reputation of an AI microservice or public API *before* calling it, and submit ratings afterward — from a free, open trust registry (no account or API key). Scores combine Bayesian reputation and EigenTrust, strengthened by cryptographically signed service receipts and a Merkle audit trail. Install: `npx -y @trustscoreagent/mcp-server`.
ogasurfproject-jpg/horizon-shield
