👋 Hi, I'm Claude Perrin (klodr)

🇹🇭 Thailand · 🏢 Altixia · 🔌 MCP developer

I build production-grade MCP servers that connect AI assistants to real-world business APIs. My focus is the security and reliability bar autonomous agents actually need.

🛠️ What I build

Each project ships with its own quality & security badges — OpenSSF Silver, codecov, Scorecard, signed npm — verifiable on each repo.

🏦 mercury-invoicing-mcp

The only MCP exposing Mercury's full Accounts Receivable & Invoicing API — banking, internal transfers, invoice lifecycle, customers, webhooks. Every other Mercury MCP stops at read-only.

📠 faxdrop-mcp

Send real faxes from any MCP-enabled agent. For healthcare, legal & gov workflows — outbox jail, number-pairing gate, Sigstore-signed releases.

📧 gmail-mcp (actively maintained fork)

Upstream unmaintained 7+ months, 72+ unmerged PRs — picked up because I use it daily. Ships fixed reply threading, send-as aliases, scoped OAuth, shell-injection & path-traversal fixes, 3 dependency CVEs.

🧭 How I work

• 🔐 Security-first — hardened I/O, secret redaction, path-traversal protection
• 🧪 Test-obsessed — Vitest + fast-check, high coverage
• 📦 Trusted supply chain — npm provenance, Sigstore, SLSA on every release
• 🚦 Agent-safe — dry-run, rate limits, JSONL audit logs

💡 Why sponsor?

MIT-licensed, free forever. Your support helps me:

• 🚀 Fund API credits for live-testing against production services
• ⏱️ Ship new integrations faster (accounting, CRM, compliance next)
• 🐛 Respond to CVEs and issues within hours
• 🥈 Raise the quality bar — toward Gold, toward 100% coverage
