Definition
What belongs in API Orchestration?
This category covers infrastructure between an agent and external APIs where discovery, credentials, policy, routing, or execution materially improves safe tool use.
Includes reusable layers between agents and external APIs that handle tool discovery, credentials, permissions, policy, routing, execution, or recovery.
Scope
Inclusion and exclusion criteria
Include when
- The product gives agents a documented way to discover and invoke APIs, tools, or skills.
- Credential protection, permissions, policy, or execution mediation is a core capability.
- It provides a reusable orchestration layer rather than one isolated integration.
Exclude when
- It is a conventional API gateway or client with no substantive agent workflow.
- Its agent support is limited to exposing an existing endpoint through a thin wrapper.
Selection guide
How to compare these tools
- How are tools discovered and described to the agent?
- Where do credentials live and how is access constrained?
- What approval, logging, retry, and error-handling controls exist?
Typical use cases
- Expose a governed catalog of APIs or skills to agents
- Mediate credentials and permissioned tool execution
- Approve, log, retry, and recover agent API calls
Category evidence
Sources for this category guidance
- Model Context Protocol tools specification
The MCP tools specification defines how models discover schema-described tools and invoke them, while recommending user visibility and confirmation for tool calls.
