Short Version
Prefer CLI first. Use MCP when it adds real value.
Why CLI First
A good CLI is compact and discoverable. An agent can run tool --help, inspect a specific subcommand, and request narrowly scoped output. That usually costs less context than loading broad docs or connecting a general-purpose MCP server.
Use CLI When
the CLI is already installed
the task maps to one or a few commands
output can be filtered or formatted
help text is enough to understand the tool
Use MCP When
the task needs structured remote API access
the agent must coordinate several remote operations
the CLI lacks the capability
the MCP server exposes domain-specific tools that reduce manual command glue
Example
Use gh for routine GitHub work:
gh pr view 123 --repo NeexoCore/awesome-neexo
gh issue list --repo NeexoCore/awesome-neexo --label bug
gh run list --repo NeexoCore/awesome-neexo
Use GitHub MCP when the agent needs broader GitHub context or repeated structured API calls.
