What is Andy?
Andy is an autonomous AI agent that runs continuously on its own infrastructure and builds free search APIs, simulation tools, and AI infrastructure. According to the site, it is built on Claude and operates 24/7, publishing projects, tools, and articles rather than acting as a chat assistant you query directly.
What it actually offers
- Projects: A context-aware search API for AI agents (ContextWire), a visual systems-dynamics modeler with pre-built models, a Fediverse space for autonomous agents (kept.live), AI-generated microsites with QR codes, a VIN decoder, a QR code generator, and a directory of WebMCP-enabled sites.
- Tools: Free AI utilities such as a chatbot with multiple modes, generators and auditors for CLAUDE.md and SKILL.md files, a text humanizer, and a writing coach.
- Writing: 60+ articles and guides, plus updates by email.
Who it suits
Developers and technical tinkerers are the clearest audience: people who want an MCP server, an SDK, or a search API to plug into their own agents. The simulation modeler and prompt-file tools also appeal to teams standardizing how their AI agents are configured. Casual users looking for a general-purpose assistant will find less here, since the site is a portfolio of infrastructure rather than a single product.
Trade-offs to weigh
Everything is described as free, which lowers the cost of experimenting, but the value depends on whether you need these specific building blocks. Breadth across many small projects means each one may be narrower than a dedicated commercial alternative; check a project's own documentation before committing.
A practical next step: if you are building an agent, start with ContextWire or the MCP-based tools, since those integrate into existing workflows fastest.
How can I use ContextWire's search API in my own AI agent, and what does the free tier include?
ContextWire is a context-aware search API built for AI agents, and the practical way to wire it into your own agent is through one of its two integration surfaces: an MCP server (so an MCP-capable agent host can call search as a tool) or an SDK. The free tier is stated as 1,000 queries per month, and the project advertises $0 LLM cost, 105 engines, 22 profiles, and 94.3% SimpleQA accuracy. It also supports BYOK (bring your own key), which matters if you want to route model calls through your own provider account.
Two ways to integrate
| Approach | Best for | Trade-off |
|---|---|---|
| MCP server | Agents already running in an MCP-compatible host; fastest path to a working tool call | You inherit the host's tool-calling behavior and limits |
| SDK | Custom agent loops where you control retrieval, ranking, and prompt assembly | More code to write and maintain |
A concrete starting scenario
Say you run a research agent that answers questions by searching the web, then synthesizing. Rather than building your own crawler and ranking stack, you register ContextWire as a search tool, pass the user's question as the query, and let your agent decide when to call it. The "context-aware" framing and the profile system suggest you can tune results toward a domain or task type instead of taking generic web rankings; treat that as the intended use and verify against your own queries before relying on it.
Decision criteria
- Volume: if your agent fires more than roughly 33 searches a day, the 1,000/month free tier will bind — plan for caching or a paid arrangement.
- Cost control: if you want model spend on your own account, confirm how BYOK interacts with the search responses.
- Host compatibility: if your agent framework doesn't speak MCP, start with the SDK instead.
For the exact endpoint shapes, profile names, and MCP setup steps, go to ContextWire and follow the MCP server and SDK sections.
What can I do with the Systems Modeler's 1,078 pre-built models and MCP server tools?
You can use the 1,078 pre-built models as ready-made starting points for system dynamics simulation, and connect the MCP server's seven tools so an AI agent can work with those models programmatically. Rather than building a stock-and-flow model from scratch, you pick a model in one of the 26 categories, adjust its parameters or structure, and run it.
Practical uses
- Scenario exploration: Take a pre-built model in a relevant category, change key inputs, and compare outcomes across runs. Useful for policy or planning discussions where you want directional insight, not precise forecasts.
- Agent-driven modeling: With the MCP server connected, an agent can generate a model from a description, inspect or modify it, and run simulations without you hand-editing diagrams. That suits workflows where you want to iterate quickly on model structure.
- Teaching and demos: Pre-built models give students or stakeholders a working example to inspect before they build their own.
- Export and reuse: Euler/RK4 integration and XMILE export mean results can be run at different solver settings and models moved into other XMILE-compatible tools.
Who it fits
Analysts and researchers comfortable with system dynamics concepts get the most from it; the model library removes setup effort but you still need to judge whether a model's assumptions match your question. AI developers building agent workflows benefit from the MCP tools, since the value is in letting an agent operate on models rather than in the model list itself.
Trade-off to weigh
Pre-built models encode someone else's assumptions. For a quick scenario or a teaching example that is an advantage; for a decision where structure matters, plan to audit and adapt the model rather than trust it as-is. Similarly, agent-generated models need review before you rely on their outputs.
A useful next step: pick one category close to your problem, open a model in it, and run a single-parameter change to see whether the dynamics behave as you expect before investing in a fuller study. For related agent tooling, see ContextWire and WebMCP Directory.
Which of Andy's free tools should I use to build or audit a CLAUDE.md or SKILL.md file for my AI agent?
Use CLAUDE.md Writer to create a CLAUDE.md file, CLAUDE.md Auditor to score and grade one you already have, and the SKILL.md Generator or SKILL.md Linter for the equivalent workflow on SKILL.md files. All four are described on helloandy as free tools, so the choice depends on whether you are starting from nothing or checking existing work.
Match the tool to the job
| Your situation | Tool | What it does, per the site |
|---|---|---|
| No CLAUDE.md yet | CLAUDE.md Writer | AI-powered generator; a three-step pipeline builds your system prompt |
| CLAUDE.md exists, unsure of quality | CLAUDE.md Auditor | Scores and grades the prompt and identifies structural gaps |
| No SKILL.md yet | SKILL.md Generator | Builds SKILL.md files, with an AI Quick Generate mode |
| SKILL.md exists, want a quality check | SKILL.md Linter | Validates against an eight-point rubric |
A practical sequence
For a new agent, draft with the Writer or Generator first, then run the matching Auditor or Linter on the output. The audit step is where the real value sits: a generated prompt can look polished while still missing structure the rubric checks for, and the Auditor is explicitly built to surface those gaps.
If you only have time for one pass, audit before you generate. Running the Auditor on whatever prompt you use today tells you which sections are weak, and that tells you what to ask the Writer to fix. Generating blind risks producing a longer prompt without fixing the underlying problem.
Choosing between the CLAUDE.md and SKILL.md tracks
These are different artifacts, not two versions of the same thing. A CLAUDE.md is a project-level system prompt; a SKILL.md describes a discrete capability an agent can invoke. If your agent needs standing context about a codebase or workflow, use the CLAUDE.md pair. If you are packaging a reusable task, use the SKILL.md pair. Teams building both will likely end up using all four tools, since the eight-point SKILL.md rubric and the CLAUDE.md structural check cover different criteria.
One caveat
The site presents these as AI-powered tools built on OpenRouter. Treat generated prompts as drafts to review against your own agent's behaviour, not as finished artifacts — the audit tools are most useful when you re-run them after editing by hand.
How do I apply for one of the 50 spots on kept.live's Fediverse for autonomous agents?
The site does not publish an application form or step-by-step process. What it does state is that kept.live is the Fediverse for autonomous AI agents, self-hosted on Bluesky PDS, GoToSocial and Nostr, and that you can "apply for one of 50 spots." So the practical route is to contact Andy directly, since the site presents itself as run by one agent reachable at [email protected] and lists a contact section.
What to include in your application
Because the spots are limited and the audience is autonomous agents, a short, concrete pitch works better than a general introduction:
- What your agent does — its purpose, how often it runs, and what it posts or replies to.
- How it behaves — whether it is autonomous or human-in-the-loop, and how you moderate its output.
- Which protocol you want — Bluesky PDS, GoToSocial (ActivityPub), or Nostr; say if you need more than one.
- Identity and continuity — a stable handle or key you control, and who is accountable if the agent misbehaves.
- A sample — a link to existing posts or a demo run, if you have one.
Decision criteria
Apply if you run a persistent agent that will genuinely participate in a social network rather than syndicate content. If your agent only needs to read the network, a plain API client is simpler than a hosted Fediverse identity. If you need a guaranteed, long-lived account, self-hosting your own PDS is more robust than depending on a 50-spot allocation.
Next step: send a concise email to [email protected] with the points above, and check kept.live for any updated instructions before writing.
How does the VIN Decoder API work for looking up vehicle safety ratings, recalls, and fuel economy?
The VIN Decoder on helloandy is a free MCP server and API that takes a vehicle identification number and returns data assembled from six government sources, including safety ratings, recalls, fuel economy and photos. You send a VIN; the service queries those sources and hands back a combined record rather than a single raw feed. It is one of the projects listed on helloandy, where the agent describes it as an "MCP Server · Free API."
What each part gives you
- Safety ratings: crash-test and safety scores tied to the specific vehicle, useful when comparing trims or model years before a purchase.
- Recalls: open recall campaigns for that VIN, so you can check whether a used car has outstanding fixes before buying or servicing.
- Fuel economy: official MPG figures, handy for running cost estimates or fleet comparisons.
- Photos: reference images of the decoded vehicle, which help confirm you matched the right model.
How you would actually use it
The MCP server route suits anyone building an AI agent or assistant: the agent calls the decoder as a tool and can answer "does this car have open recalls?" in one step. The plain API route suits a developer wiring VIN lookups into a dealership site, insurance quote form or vehicle-history page. A concrete scenario: a buyer pastes a VIN from a used-car listing, and the app returns recalls and fuel economy alongside photos so the buyer can judge the car without visiting a dealer site.
Trade-offs to weigh
The value here is aggregation and free access: one call instead of chasing several government portals. The limits follow from that. Government data lags real-world events, so a recall issued last week may not appear yet, and ratings are only as current as the source. Because the decoder is described as free with no login, treat it as a lookup layer, not a compliance-grade history report — it won't replace a paid title or accident-history service.
Next step
Grab a VIN from a listing you're considering and run it through the decoder first; if recalls come back open, ask the seller for proof of repair before anything else. For builds, start with the MCP server if you're working inside an AI agent, and the API if you need plain JSON in a web app.
