Features

Built for both human developers and AI agents.

OpenAPI-native

Parses the unified Apideck OpenAPI spec directly. No generated code, no SDK dependency.

Beautiful TUI explorer

Interactive API playground in the terminal. Browse APIs, resources, and operations.

AI agent-ready

agent-prompt outputs a token-optimized prompt (~80 tokens vs ~3,600 for MCP).

Permission engine

Auto-classified operations (read/write/dangerous) with built-in safety rails.

Why CLI?

Compare the CLI to other approaches for AI agent integration.

Dimension	curl + OpenAPI	MCP	Apideck CLI
Context cost	~5,000–50,000 tokens	~3,600 tokens/API	~80 tokens
Auth handling	Manual, per-request	Per-server, inconsistent	Automatic
Safety/Permissions	None	Optional, per-server	Built-in
Discovery	Load entire spec	Schema dump upfront	Lazy, progressive
Runtime deps	None	Server process	None (static binary)
Agent compatibility	Any (shell)	MCP clients only	Any (shell)

AI Agent Integration

Run apideck agent-prompt to generate a token-optimized prompt (~80 tokens) that teaches any AI agent the CLI. Use apideck skill install to write a Claude Code skill so your agent automatically knows Apideck.
