Overview

Description from the maker (original English)

Build, deploy, and sell AI agents for local-service businesses - from your IDE.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

Common questions

Is Seldonframe MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.59.2) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: GitHub, Desktop Commander, Cloudflare MCP

SeldonFrame

Sell AI front offices. Deploy them in minutes.

SeldonFrame is the agent-native, open-source alternative to GoHighLevel for agencies serving local businesses. Give your coding agent a client's URL and it can create a branded website, booking flow, intake, CRM, and AI agent in one workspace. Run evals, publish, and hand it off — then operate every client from one agency view.

Website · For agencies · For builders · Docs · Discord

Live demos: HVAC · Med spa · Med spa · Weight loss


Ship your first client front office

claude mcp add seldonframe -- npx -y @seldonframe/mcp

Or as an auto-updating Claude Code plugin:

/plugin marketplace add seldonframe/seldonframe

/plugin install seldonframe@seldonframe

Build a branded AI front office for my HVAC client in New Orleans.

✓ Workspace ready at acme-hvac.app.seldonframe.com

Build the first client workspace before paying. Hosted Managed uses SeldonFrame's keys; Builder and Agency plans are BYOK. Your agency owns the client relationship, workspace data, and delivery margin.

See a real one — a live workspace, not a mockup:

The generated site — quote intake, reviews, and the chat agent (bottom right) Its booking page — the real calendar the agent books against

And here's the agent on that site handling a real inbound — checking the live calendar, and, when asked for a price, *refusing to invent one* (that's the quote-guard, not a scripted reply):

A genuine exchange with the chatbot on the live site — nothing scripted:

It reads the real calendar. "Today's fully booked — here are tomorrow's 9/10/11 AM slots." It won't lie about price. Asked what a visit costs, it says "I don't have exact rates on hand, but I'll have a technician confirm the cost before any work starts" — the quote-guard in action, not a canned line. It qualifies to book. Asks for the service address to confirm you're in-area, then locks the slot.

Same agent answers on SMS and voice too — the channel is just a config knob.

Click any screenshot — this HVAC workspace is live and books real appointments. More live workspaces: Metro MedSpa · SKINNEY Medspa · Vive Ageless Weight Loss — and more on seldonframe.com.


The agency delivery loop

  1. Start with the client URL. SeldonFrame extracts the business facts and creates the workspace.
  2. Apply your agency playbook. Brand the site, booking flow, intake, CRM, and agent.
  3. Verify before handoff. Run evals and complete a real test booking.
  4. Publish and operate. Give the client a branded portal while your agency keeps the master view.

The same loop works from the dashboard, Claude Code, Cursor, Windsurf, or any MCP-compatible agent. See the agency workflow.


What an agent is made of here

Most "agent frameworks" hand you a chat loop and wish you luck. SeldonFrame gives your IDE agent the full production anatomy:

The agent model — Trigger × Skill × Channel

An agent isn't a chatbot UI; it's three independent axes:

  • Trigger — *when it runs*: inbound (a call / chat / email / SMS arrives) · event (a domain event fires — booking.completed, lead.created, invoice.paid…) · schedule (a cron cadence).
  • Skill — *what it does*: receptionist · review-requester · speed-to-lead · win-back · digest…
  • Channel — *how it speaks*: voice · web chat · SMS · email · internal digest.
  • Tools — *what it can touch*: native tools (book against the real calendar · read/write the CRM · send SMS & email · take a message) plus 1,000+ app integrations via Composio (Google Calendar, Sheets, Slack, HubSpot, Notion, …), bound per-agent.

surface: voice | chat (the old receptionist-only knob) is just one point in this space — trigger=inbound. One builder creates any agent; the marketplace sells any agent.

From agent to production *loop*

A production agent is a loop, not a single prompt:

Trigger → (Model + Tools + State) → Verify → Iterate, bounded by a Stop condition, improved by Evals, kept honest by Observability + Guardrails.

Two non-negotiables drive the roadmap: the checker must be separate from the maker (a model grading its own work is too generous a grader), and the loop must have brakes (or it bills you in silence). Where each primitive stands today:

PrimitiveStatusWhat's there
Trigger✅ ShippedInbound + event triggers on the SeldonEvent bus. booking.completed → review-requester; lead.created → speed-to-lead, both sending outbound SMS/email.
State✅ ShippedAgent loop-memory in Brain v2 — agents recall what they did before acting and record after. The review "ask once per customer" throttle is now a memory recall, not a bespoke flag.
Verify (maker ≠ checker)✅ ShippedDeterministic validators grade every run — pass rates surface on each agent's health card and /runs; run_agent_evals replays scripted scenarios. Rolling out: the same checker as a hard pre-send gate + an LLM judge for judgment calls.
Guardrails / Stop✅ ShippedQuote-guard (never invent prices), enforced read-back before booking, per-contact throttles, booking-policy enforcement (hours · duration · required fields), hard call/iteration caps. Rolling out: generic token-budget brakes for long-looping agents.
Generate-by-default✅ ShippedOne English sentence → trigger + skill + channel + tool bindings + guardrails, generated together. *"text every customer for a Google review the day after their job — never twice, only if completed"* compiles into a real agent. The generate_agent MCP tool and the Studio wizard both run this pipeline.
Record → Agent🗺 RoadmapSkip describing it — screen-share your workflow once. SeldonFrame watches, compiles the steps into a draft agent (skill + tool bindings + eval scenarios derived from the recording), and you deploy in minutes. Live behind a flag at /record; becoming the default on-ramp next.
The loop, drawn

One sentence builds it; triggers drive it; the ring is the loop *running* — Model → Tools → State → Verify — with tools orbiting the core, /runs + Brain observing, and the Stop brakes bounding every pass. Everything in the diagram is shipped today. *(Animated SVG — if your viewer freezes it, the still frame reads the same.)*

Anything you describeanyone English sentenceanyThe Studio wizard adapts its questions to the primitives your agent needs.

The Brain — memory that compounds

Agents that forget are demos. Every SeldonFrame workspace owns a Brain:

  • The Soul — the single source of truth an agent grounds on (identity, services, hours, pricing). Install someone else's agent and it re-grounds on *your* Soul, never their facts.
  • Loop memory — agents recall before acting and record after. "Did I already ask this customer for a review?" is a memory recall, not a bespoke flag.
  • Notes → distilled rules — raw observations get compiled and promoted into durable knowledge on a schedule, so every run starts smarter than the last one ended.

Money rails, built in

Agents that do real work end up touching real money — so the rails are platform primitives, not an integration project:

  • A prepaid wallet ledger — UNIQUE idempotency keys and guarded never-negative decrements: a charge can't double-fire, a balance can't go below zero.
  • Stripe Connect payouts — seldonframe payout moves accrued earnings to a bank account.
  • Checkout that fulfills — a marketplace sale auto-provisions the deployment and re-grounds it on the buyer's business.
  • Per-use rental billing — every agent exposes a signed MCP endpoint; other LLMs can rent it and the ledger meters each use.
  • Real phone numbers — provision a number per agent (bring your own Twilio today; SF-managed metered numbers are rolling out).
