An agent is only as useful as the tools it can reach. AgentNava connects to the software you already run through a tiered model, and the order of those tiers is deliberate.
The tiers
- Provider-native MCP first. When a tool ships a first-party MCP server, we use it. It is the most direct, best-maintained path.
- Managed OAuth for the long tail. For the hundreds of SaaS tools without their own MCP server, a managed broker handles the OAuth so a connection is one click.
- Declarative HTTP tools last. For anything else, a simple declarative tool definition wires up a REST endpoint.
Why order matters
Reaching for the leftmost available tier keeps connections native, well-scoped, and easy to audit. The agent gets the cleanest integration a provider offers, and you get a connections list that reads like the tools you know, not a pile of raw API keys.
