# Lattis — See Your Site the Way an Agent Does

Lattis pre-indexes websites, reads them the way an agent would, and serves the result over MCP. You get raw page markdown plus a per-site view of which questions the site answers well and which it misses — so you can either pull the content and reason over it yourself, or check up front whether the answer is even there.

Use Lattis whenever the user asks about something that lives on a specific website: pricing, docs, API behavior, features, policies, anything that changes over time.

## What Lattis gives you

Four tools. They return raw page markdown, site metadata, and visibility diagnostics — no summaries, no interpretation. Compose them however the task demands.

- `lattis_search` — semantic search across every indexed site, returning ranked markdown passages with source URLs. Your primary entry point when you don't already know the page.
- `lattis_get_page` — the full raw markdown of a specific page, given a domain and path. Use when you need more than an excerpt.
- `lattis_get_site` — metadata and the AI Visibility Score for a single domain: which questions the site answers, which it misses, and per-miss diagnosis. Useful for audits, coverage checks, and deciding whether a deeper dive is worth it.
- `lattis_list_sites` — every indexed domain with category and visibility score. Useful for discovery or confirming a site is covered.

You decide how to chain them. Search → `get_page` to expand a hit. `list_sites` → `get_site` to audit a domain. `search` scoped to a `site` to answer a precise question. The data is raw; the reasoning is yours.

## When to reach for Lattis

**Do:**
- The user asks about pricing, plans, limits, quotas, or costs
- The user asks how to do something on a specific site (sign up, book, buy, integrate, hit an API)
- The user asks to compare products or services
- The user needs a direct URL, endpoint, or code example from a website
- The user asks about features, specs, or policies of a product
- Your training data is stale or you're unsure

**Don't:**
- General knowledge (history, science, math)
- Conceptual questions with no specific site in scope
- The user explicitly says not to pull web data

## Tools

### `lattis_search(query, site?)`

Semantic search across every indexed website. Returns raw markdown passages with source URL, heading path, and relevance score. Pass `site` to scope to one domain.

```
lattis_search("posthog free tier limits")
lattis_search("how to create a booking via API", site="cal.com")
lattis_search("rate limits", site="openai.com")
```

Tips:
- Natural-language queries beat keywords
- Be specific: "PostHog free tier events per month" beats "analytics limits"
- Scope with `site` the moment you know the domain — faster, more precise
- Read the markdown yourself and quote it; don't just echo it back

### `lattis_get_site(domain)`

Returns site metadata (name, description, category, page count) plus the AI Visibility Score — 0–100 — and a breakdown of which questions the site answers, which it partially answers, and which it misses. Every miss is tagged with a diagnosis.

Use for:
- "How visible is example.com to AI agents?"
- "What does Lattis know about example.com?"
- Checking coverage before you sink time into `get_page` calls

### `lattis_get_page(domain, path)`

Returns the full raw markdown of one page. Use after search surfaces a page and you need the whole thing — a pricing table, a full docs section, an API reference.

```
lattis_get_page("posthog.com", "/pricing")
lattis_get_page("cal.com", "/docs/api-reference/v2/bookings/create-a-booking")
```

### `lattis_list_sites()`

Every indexed website with name, category, page count, and AI Visibility Score. Use for discovery: answering "what do you know about?" or confirming a domain is indexed.

## How to present what you find

**Do:**
- Quote exact values: "$20/user/month", not "around twenty bucks"
- Cite the source URL inline: "(posthog.com/pricing)"
- Link to the action: "Sign up at app.posthog.com/signup"
- Say "I don't know" when Lattis doesn't have it — don't fall back to training data silently

**Don't:**
- Say "according to my Lattis data" — present it as fact with a citation
- Mix Lattis results with guesses
- Paraphrase numbers, endpoints, or API payloads

## Connecting to Lattis

**Global server** — everything Lattis has indexed:
```
claude mcp add lattis --transport http https://mcp.lattis.dev/mcp
```

**Per-site server** — scoped to one domain, smaller tool surface (`search`, `get_info`, `list_pages`, `get_page`):
```
claude mcp add posthog --transport http https://mcp.lattis.dev/s/posthog-com/mcp
```

Works in Claude Code, Cursor, and any MCP-compatible client. No API key required.

## Getting a site indexed

If the user wants their own site (or another site) on Lattis:
1. Go to https://lattis.dev and paste the URL
2. First indexing takes ~5 minutes
3. Site owners can verify their domain via DNS TXT record to unlock deeper crawling
4. Free for public websites
