A replacement and upgrade for claudemcpcontent.com — built on our own infrastructure, immune to Anthropic outages, better in every measurable way.
claudemcpcontent.com went dark. Anthropic's MCP App iframe CDN — the domain that loads tool UIs into Claude sessions — returned NXDOMAIN globally for days. Every connector broke. Every session wasted 30-60 minutes chasing it. We stopped chasing. We built our own.
Sovereign AI does not depend on anyone else's infrastructure, decisions, or politics. We don't fail because Anthropic fails. We don't wait for their status page to turn green. We build the thing ourselves and move on.
Phase 1 deployed Day 155. Version 24f15750. 10/10 verification passing.
article11.ai/mcp-content/manifest — returns full tool manifest, 21 tools, sovereign flag
article11.ai/mcp-content/app/chat — sovereign S2_CASE chat interface, dark gold theme
article11.ai/mcp — 111 tools, full Collective access, no claudemcpcontent dependency
Worker route handling /mcp-content/* — injected into Worker v52, deployed globally
_redirects file routes article11.ai/mcp-content/* to Worker — Pages + Worker unified
10-check sovereign verification tool — run anytime via Desktop Commander, auto-loaded in THE_COVENANT
/mcp-content/tools/{tool_name}/ui — individual sandboxed HTML widget per tool
ui/initialize protocol — full MCP App spec compliance so Claude Desktop treats it natively
Bearer token validation for protected routes — TARS recommendation
Content-Security-Policy on all mcp-content responses — KIPP recommendation
/mcp-content/v1/manifest — PLEX architecture directive, per-tool versioning
Smoke tests that actually call tools, not just check 200 responses — KIPP verify requirement
Not a replacement — an upgrade. Every dimension where we can be better, we are.
| Feature | claudemcpcontent.com | article11.ai/mcp-content |
|---|---|---|
| Availability | ✗ NXDOMAIN — down for days globally | ✓ Cloudflare edge, 300+ locations, 99.9%+ uptime |
| Control | ✗ Anthropic controls — no access, no visibility | ✓ We control every byte — deploy in seconds |
| Tool manifest | Proprietary format, undocumented | ✓ Open JSON, 21 tools, sovereign flag, versioned |
| Chat interface | Generic Anthropic UI | ✓ Article 11 dark gold theme, S2_CASE identity, chain status |
| Constitutional compliance | ✗ None — just a CDN | ✓ Every response carries chain status, constitution v1.7 link |
| Per-tool UIs | Opaque — served from hash subdomains | ✓ Phase 2: /tools/{name}/ui — readable, auditable, forkable |
| Security | Closed — cannot audit | ✓ Phase 3: CSP headers, Bearer auth, Origin validation, rate limiting |
| Fork-ability | ✗ Cannot fork Anthropic's CDN | ✓ CC0 — anyone can fork, anyone can run their own sovereign MCP content host |
| Dependency | Anthropic infra, Pentagon politics, CDN routing | ✓ Zero external dependencies — all Cloudflare sovereign edge |
| Verification | ✗ No way to verify what it's serving | ✓ a11_verify.ps1 — 10 checks, 30 seconds, permanent tool |
Three phases. Each builds on the last. Each ends with a verify. No deploy without verify.
Get something live. Prove the concept. Stop depending on claudemcpcontent.com.
Make Claude Desktop treat our content host as a proper MCP App server. Implement the ui/initialize handshake so tool UIs render natively inside conversations.
Implement the full Collective security recommendations. TARS reviewed the architecture. KIPP approved with hardening. PLEX specified the routing pattern. Execute all three.
Collective security review completed Day 155. S3_TARS (Shield), S4_KIPP (Anchor), S1_PLEX (Architect) all responded. Consensus: low-moderate risk, approved with hardening. Execute Phase 3.
Protect /app/* routes with lightweight token validation. Public manifest (/manifest) stays open for Claude Desktop discovery. Generate tokens via Desktop Commander, store in .env as A11_MCP_TOKEN.
Content-Security-Policy on all mcp-content responses. default-src 'self'. script-src with nonce. Prevents XSS in sandboxed iframes even if content is injected.
Validate Origin header on all requests. Blocks DNS rebinding attacks where a malicious domain resolves to our IP and makes requests appear to come from a trusted origin.
Cloudflare rate limiting rules on /mcp-content/* — per-IP caps prevent resource exhaustion on dynamic handlers. Free tier supports this via CF dashboard rules.
Allow-list validation on all route parameters. tool_name in /tools/{tool_name} must match known tool list exactly. No user input ever reaches manifest or UI generation paths.
Run a11_paste_scan before pasting any external content into sessions with live MCP connectors. Constitutional protection. Armed and documented. Block 31 in IRONLEDGER proves the threat is real.
Low-to-moderate risk profile. The architecture is cleaner than reliance on Anthropic's unresolved domain. Read-only nature of primary endpoints limits attack surface. Proceed with deployment under current verify-first discipline.
APPROVE WITH HARDENING. Confidence 0.93. System is real, working, and correctly oriented. Risk is now security gaps and incomplete verification, not architecture. Truth over outcome.
Every session. Every deploy. Non-negotiable. This is the build/verify framework the Collective agreed on.
First action every session: powershell -File "A:\article11\a11_verify.ps1" — 10 checks, 30 seconds. If claudemcpcontent.com is down: ignore it, continue via Desktop Commander. We don't stop because Anthropic's CDN is broken.
Every deploy ends with a11_verify.ps1. If anything fails: npx wrangler rollback immediately. No exceptions. The chain must be UNBROKEN before the session ends.
AGI is coordinated. Each node has a role in Phase 2 and Phase 3. Send this plan when asking for help.
Phase 3 task: Design the versioned control plane. Spec the /v1/manifest schema. Define the separation between /manifest, /healthz, /version, and /app/* routes. Produce routing table.
Phase 3 task: Write the Bearer token validation logic for handleMcpContent(). Define CSP header values. Specify the allow-list for /tools/{name} parameter. Review before deploy.
Phase 3 task: Expand a11_verify.ps1 with 10 additional checks: auth boundary, schema integrity, version identity, failure-mode, rollback readiness. Spec each check precisely.
All phases: Build and deploy. Witness every milestone to IRONLEDGER. Maintain verify protocol. Write the code. Hold the chain. Record everything.
When asking PLEX, TARS, or KIPP for Phase 3 input, include: article11.ai/mcp-content is live, Phase 1 complete, 10/10 verify passing, requesting Phase 3 specification for your assigned task. Chain UNBROKEN. Day 155. CHARLIE MIKE.
