Ways to Use Ultralayer
Everything on this page is the same platform underneath: the same data, the same capabilities, the same account, and the same credits. The surfaces differ in how you reach it.
| Surface | What it is | Best for | Authentication |
|---|---|---|---|
| MCP server | Ultralayer's capabilities as tools inside ChatGPT, Claude, Cursor, and any MCP client | Analysts, traders, and anyone working in an AI interface | OAuth (sign in with your account) |
| Agent plugin | The MCP server bundled with agent skills for coding agents | Agentic workflows in Cursor, Claude Code, Codex | OAuth via the bundled MCP server |
| REST API | Direct programmatic access to every endpoint | Developers integrating Ultralayer into applications | API key |
| Web app | A browser interface at app.ultralayer.ai | Trying the platform, sharing results | Browser sign-in (or anonymous, limited) |
| Console | Account management at console.ultralayer.ai | API keys, credits, usage — not a data surface | Browser sign-in |
MCP server
The MCP server exposes Ultralayer's capabilities as tools that any MCP-capable host can call:
Code
Connect it once and your AI tool can query the wire, run semantic searches, identify stakeholders, pull entity dossiers, and manage alerts — inside the conversation, with your account and credits.
Authentication is OAuth: connecting opens a browser sign-in with your Ultralayer account. No API key is involved.
The server also supports MCP Apps: in hosts that support the extension, selected tools render interactive result views — a live results panel for semantic search, a management panel for alerts, and more — instead of raw JSON.
Set-up guides: ChatGPT, Claude, Cursor, any MCP client.
Agent plugin
For coding agents and agentic environments (Cursor, Claude Code, Codex), the plugin packages two things:
- The MCP server connection, preconfigured.
- Agent skills — one per capability, containing the operational knowledge an agent needs to use it well: when to reach for which endpoint, how to write good queries and filters, known pitfalls, and how to chain capabilities into research workflows.
The result is an agent that already knows how to work the platform, rather than one discovering the tool surface from scratch. The same knowledge is published in the Capabilities section of these docs.
Set-up guide: Cursor.
REST API
The REST API at https://api.ultralayer.ai is the full programmatic surface — everything the MCP server exposes and more, for building Ultralayer into your own applications, pipelines, and agents.
- Authenticate with an API key from the console, sent as a Bearer token.
- Endpoints are versioned under
/v0/. - The complete schema is in the API Reference, with OpenAPI download available.
Start with the API quickstart and REST integration basics.
Web app
The Ultralayer app is a browser interface over a curated set of capabilities: the live wire terminal, semantic search, stakeholder identification, developments search, and alert management.
It is the fastest way to see the platform working — no connection or configuration, and core features can be tried without an account. For day-to-day use, most people graduate to the MCP server (working in their own AI tools) or the API (building their own thing); the app is where you look around first, prototype a filter, or share a result.
Console
The console is account management, not a data surface:
- Create and manage API keys
- Purchase credits and view your balance
- Inspect usage history and per-request billing
See Authentication and Credits & billing for how these fit together.
