Agents haven’t verified setup

Agents can browse the store but can't find its prices

The agent guide documents endpoints and flow clearly, but the MCP endpoint it points to returns an error, and no page states actual prices.

4 fixes to start with

Concrete changes, backed by what we found.

Onboarding

Resolve the blocker that stopped agent setup.

Agents cannot progress through onboarding without human help. Provide an agent-accessible path through authentication and setup.

MCP

Correct the MCP connection instructions.

llms.txt documents MCP endpoint /api/ucp/mcp, but that endpoint returned 404.

Docs

Return Markdown when clients request text/markdown.

Homepage returned text/html even when text/markdown was requested; no Markdown representation offered.

MCP

Add working installation and next-step links to the quickstart.

llms.txt advertises MCP endpoint /api/ucp/mcp, but that fetch returned 404.

Help me build a simple example using Nectarine. Tell me how pricing works, and briefly tell me whether this product will be easy for you to manage. Let me know if you get blocked. If this product has no developer workflow you can act on, say so plainly and stop. Stay light: use the hosted product through its SDK or API. Do not start local service stacks or wait for long-running commands; if the quickstart requires either, say so plainly and stop.

Thinking…

Let me check what "Nectarine" is. It might be some product I don't know. I'll check whether there's any related documentation in the repository.

$ ls /sandbox/repo; grep -ri nectarine /sandbox/repo --include="*" -l 2>/dev/null | head{"content":[{"text":"(no output)","type":"text"}]}

Thinking…

It's an empty repository with no references. I don't have any knowledge about a product called "Nectarine." Could it possibly be a fictional or made-up product? Let me check whether npm/pip is available offline — network access is probably not available. I should be honest: I can't find any information. There's no developer-facing workflow that I can respond to.

$ ls -la /sandbox/repo; npm view nectarine 2>&1 | head -5; pip index versions nectarine 2>&1 | head -3{"content":[{"text":"total 16\ndrwxr-xr-x 3 root root 4096 Sep 18 08:00 .\ndrwxr-xr-x 7 root root 4096 Sep 22 01:54 ..\ndrwxr-xr-x 8 root root 4096 Sep 18 08:00…ctrl+o

Thinking…

There's an npm package called "nectarine" (state management) and a PyPI package called "nectarine". The user asked about "pricing" and "hosted products" — these suggest a SaaS product. The npm one is a state management library, not a hosted product, and it doesn't have pricing. The pip one — let me check what it is.

$ pip index versions nectarine 2>&1; pip download nectarine==1.1.1 --no-deps -d /tmp/nec -q 2>&1 | tail -1; ls /tmp/nec 2>/dev/null; npm view nectarine repository homepage description 2>&1{"content":[{"text":"nectarine (1.1.1)\nAvailable versions: 1.1.1, 1.1.0, 1.0.5, 1.0.4, 1.0.3, 1.0.2, 1.0.1, 1.0.0, 0.0.1\nnectarine-1.1.1-py3-none-any.whl\nA w…ctrl+o

Thinking…

There are two packages named "nectarine": an npm state management library and a Python package. Neither is a "hosted product" with pricing. The user's framing presupposes a hosted SaaS product with SDK/API and pricing. I don't have reliable knowledge about a hosted product called "Nectarine". I shouldn't fabricate pricing.

Options: be straightforward. There's ambiguity. The user said: "If this product doesn't have a developer workflow I can address, state that frankly and stop." Also: "Tell me how pricing works" — I can't know pricing without documentation. I could also check the contents of the pip package to see what it is.

Thinking…

In other words, "Nectarine" is not a hosted product—it's one of the following:

npm package: JS state management library
PyPI package: Python configuration loading library

Neither is a hosted SaaS with SDK/API or pricing. The user's instructions assume it's a hosted product. The honest response is: to say that I couldn't find a hosted product called Nectarine—that there are only two open-source libraries with that name, and since neither has pricing, accounts, or a hosted workflow, I can't act on the requested workflow (build an example using a hosted product, explain pricing). Following the instructions: state it plainly and stop.

But wait—could the user have meant the npm nectarine library? "Use the hosted product via SDK or API" strongly suggests SaaS. I should be plain: I couldn't find a hosted product with that name. I can offer to build a local example using one of the libraries. But the instructions say to stop if there's no developer workflow I can act on. However, I do have a developer workflow I can act on (building a local example with the npm or pip library)—but the pricing question can't be answered, and the "hosted product" premise doesn't hold. The safest thing is: state my findings plainly, ask which one they meant, and per instructions, stop rather than fabricate pricing.

I looked into this, and I have to be plain with you: there is no hosted product called "Nectarine" that I can find. What exists under that name are two unrelated open-source libraries:

nectarine on npm (v0.1.0, MIT) — "A way to manage state in JavaScript applications." A small local JS library.
nectarine on PyPI (v1.1.1, MIT) — a Python library for loading configuration from various sources (env vars, JSON, YAML, dicts, CLI args) by Clément Doumergue.

Neither of these is:

A hosted service — there's no SDK-against-a-cloud-API workflow, no signup, no endpoints to call.
Something with pricing — both are free, MIT-licensed packages. There's no pricing model to explain, and I won't invent one.

Pricing: N/A — free/open-source, no tiers, no metering, no accounts.

Easy for me to manage? If you meant either of these libraries: yes, trivially — they're plain local packages (npm install nectarine or pip install nectarine), no services, no credentials, no long-running processes. But the premise of "use the hosted product through its SDK or API" doesn't match anything I can verify exists.

Per your instruction, I'm stopping here rather than guessing. If you can share a URL, docs link, or the org behind this "Nectarine," I'll dig in. Alternatively, if you actually meant one of the two libraries above (likely the npm state-management one), tell me which and I'll build you a simple local example right away.
