- What It Is
- AI business infrastructure — the operating system layer between AI models and business operations. Not a SaaS with AI bolted on. The AI IS the operating system. AI agents run businesses across 52 industries autonomously.
Platform Scale
AI Infrastructure
SmartRouter
AI model selection engine. 41,000+ lines. Selects optimal model per task across 7 providers (OpenAI, Anthropic, Google, Meta, Mistral, Cohere, local/Ollama), 21 task types, 4 routing tiers. Automatic failover.
CognitiveLimiter
AI cost control. 50,000+ lines. 9 safety layers, real-time Redis tracking, spike detection, per-company budgets with alerts at 50/80/90/100%.
PromptGuard
AI security layer. 5 security tiers, 41 injection patterns, canary token detection, output scanning. Prevents prompt injection and data exfiltration.
Developer Surface (Agent-Ready)
The primary user of every Solid# developer surface is an AI agent. Determinism, JSON-first output, and structured error envelopes are defaults — not opt-ins.
@solidnumber/cli
v2.6.2 — 103 verbs, 722 commands
v2.0 made structured JSON error envelopes the default — every command emits machine-readable {ok,error,hint,docs} so agents self-correct.

@solidnumber/mcp
v1.0.1 — 608 tools, 36 categories
Model Context Protocol server. One-command install into Claude Desktop, Cursor, or Windsurf:
solid mcp install <claude|cursor|windsurf>Per-tenant scoping enforced by API key + company_id at every tool call. Backed by 1,615 REST endpoints.
Themis
Apache 2.0 — open source
The run-time counterpart to Constitutional AI. Constitutional AI shapes a model during training; Themis enforces policy at every tool call, every API request, every agent action in production.
Extracted from Solid#'s internal scope/audit/T10/T12 stack. github.com/Adam-Camp-King/Themis
Magic-Link Install
ist_* install tokens
Zero-friction onboarding for AI agents. Customers generate a token at /dashboard/install-command and the agent redeems it with one command:
solid setup --install-token ist_*Wizard runs unattended: auth, editor MCP wiring, Claude hook, completion, first action.
JSON-LD Tenant Context Graph + Open-Door Commerce
Schema.org + solid:* vocab — SPARQL-queryable
Every tenant publishes a typed JSON-LD context graph. Stable @id IRIs are a public contract — extend the vocabulary via services/ai_context_jsonld.py. The CLI walks the graph offline (solid graph --offline) or against the live tenant (--remote), and supports SPARQL via --query.
Open-door commerce endpoints: tenants expose a no-auth shopping/booking surface for AI shopping agents — inventory, pricing, availability, and checkout-init are reachable without an API key (per tenant opt-in). Safety layers: mode caps, sandbox, and tenant-guard (refuses to write outside the directory bound by .solid/manifest.json).
Universal Commerce Protocol (UCP)
Phase 0 shipping 2026-04-26 — basic integration · Apache 2.0 spec
Solid# implementation of Google's Universal Commerce Protocol — the open standard for buyer-agent ↔ merchant interop. Phase 0 (basic integration) ships .well-known/ucp discovery and RFC 9421 ES256 HTTP Message Signatures with per-company JWK rotation.
https://solidnumber.com/.well-known/ucp— platform profile{tenant-domain}/.well-known/ucp— per-company business profilehttps://solidnumber.com/co/{company_id}/.well-known/ucp— tenant fallback
Solid# differentiator: stock UCP assumes one merchant = one checkout endpoint. Solid# exposes a hierarchical agent graph — platform → company owner (ADA) → functional sub-agents (sales, AR, AP, commissions, service, inventory, compliance, marketing, vertical) — each addressable per role. Buyer-agents can negotiate with sales, request invoicing from AR, onboard as a supplier through AP, escalate to service. Copycats will ship a single /checkout-sessions endpoint and call it done.
- Tier 3 sub-agent role routing (
/ucp/agents/{role}) - AP2 payment mandate verification
- OAuth identity linking ceremony
- Inbound RFC 9421 signature verification middleware
com.solidnumber.*custom capabilities (the moat)- Buy-side procurement primitives
A company's UCP presence is never auto-enabled. The company-id owner walks a 4-rung delegation ceremony with full audit trail:
- 1. Company is UCP-discoverable
- 2. Which sub-agent roles activate
- 3. Which capabilities each role serves
- 4. Auto-approval thresholds per capability
Spec: github.com/Universal-Commerce-Protocol/ucp · UCP itself is Apache 2.0
