4,000 tools. One bill.
Every Nebula agent ships with about 4,000 built-in tools on a single bill: no separate API keys to chase. OAuth into your accounts, connect any MCP, CLI, or API, and custom tools get built on the fly.
Built-in catalog
GitHub, Linear, Stripe, Postgres, Slack, and thousands more.
Your accounts
Sign in once; agents act with the access you grant.
Anything else
Any MCP server, command line tool, or HTTP API.
Coding agents
Bring your existing account; Nebula drives it.
Missing tool?
Agents write, test, and reuse custom tools.
Everything already wired.
The tax on agent platforms is integration work. Nebula deletes it: the catalog is built in, billing is unified, and the gaps get filled by the agents themselves.
4,000 tools built in
GitHub, Linear, Stripe, Postgres, Slack, Notion, and thousands more, ready on day one. Grant a tool once and every conversation can use it.

One bill, no key chase
No separate API keys to sign up for and no per-provider invoices. Tool usage draws from the same credit balance as everything else.
single billing · shared credits
Bring anything else
OAuth into the accounts you already use, or connect any MCP server, CLI, or API. Your Claude Code or Codex account plugs straight in.

Custom tools on the fly
If the tool doesn't exist, the agent writes it: a scraper, an internal API client, a one-off script. Built, tested, and reused.
agents build their own
From zero to wired.
Connecting your stack takes minutes, not sprints.
Connect an account
OAuth into the app or paste an endpoint. The tool is live for every agent you allow.

Grant it once
Access is per-workspace, not per-conversation. Nobody re-authorizes the same tool twice.
workspace-wide
Ask for the work
Agents pick the right tools per task, chain them, and show you exactly what they called.
