SyncSo

Let your agents understand what's happening locally, in real time.

Ask a model what to do in New York and it names the Whitney. It is not wrong. It is just answering from a guidebook, because that is what it has — a city as a list of places, frozen whenever the training run ended.

What it does not have is everything going on inside those places, and the thousand rooms that never make a guidebook. The Tuesday gig. The pottery class with two seats left. The night market under the bridge. Your model has never heard of any of it.

SyncSo is that missing half: live music, theater, comedy, film, art, sports, festivals, markets, food and drink, classes, tours, nightlife — the whole surface of a city, each thing carrying its dates, times, prices, booking links and images. Not one category. Not the famous parts.

Which means your agent can finally take the questions it used to hand back. Where to take a visiting parent on a Tuesday. What a couple could book three weeks out. What is free, outdoors, and happening in the next four hours. Real answers, with a link to book them.

Install

One catalogue, two doors. Assistants that speak MCP connect to https://rtdb.syncso.com/partner/mcp. Anything else reads the skill file at https://syncso.com/SKILL.md. Both open the same account: the first search asks the person to sign in once at syncso.com, and every account starts with a free monthly allowance of searches.

Claude

In Claude.ai or the Claude desktop app: Settings → Connectors → Add custom connector, paste the MCP URL, and ask. Claude also lists SyncSo in its directory, where it is one click.

In Claude Code, connect the MCP server:

claude mcp add --transport http syncso https://rtdb.syncso.com/partner/mcp

or install the skill as a plugin, which keeps itself current:

claude plugin marketplace add SyncSo-Inc/syncso
claude plugin install syncso@syncso

ChatGPT

Coming to the ChatGPT app directory. Until it is listed: Settings → Apps & Connectors → Advanced → Developer mode, add a connector, paste the MCP URL. Developer mode is not available on every plan.

Cursor, Windsurf, VS Code and other MCP clients

Add SyncSo to the client's MCP configuration:

{
  "mcpServers": {
    "syncso": { "url": "https://rtdb.syncso.com/partner/mcp" }
  }
}

OpenClaw

openclaw skills install @liangstl/syncso

Also on ClawHub, where clawhub install syncso does the same.

Coding agents that read skill folders

Claude Code, Codex, Cursor, Copilot and the rest, one command:

npx skills add SyncSo-Inc/syncso

Anything else

Tell your assistant:

Set up SyncSo from https://syncso.com/SKILL.md

The file carries the guidance and the tool definitions, works with anything that can call a tool and make an HTTPS request, and the copy at that URL is always the current one. A person using it gets their sign-in code at syncso.com/connect.

Two tools do the work, find_things_to_do and get_details. That is the whole surface.

Coverage

New York only, for now. More cities over the coming months.

Within it, everything: every category above, from the institutions down to the one-night thing in a room above a bar. Ask about anywhere else and the skill tells your model to say so rather than invent an answer — the same refusal to guess that makes the New York answers worth trusting.
