Automated summary

Generates complete production-ready CLI wrapper code for MCP servers following progressive disclosure patterns.

Strengths

  • Quickly produces a functional CLI wrapper with a 4-level help system.
  • Supports Python and TypeScript with multiple frameworks (Click, FastMCP, SDK).
  • Includes error handling, validation, and output formatting.

Limitations

  • Requires existing MCP server analysis or configuration.
  • Generated code may need adjustments for specific use cases.
  • Limited to the mentioned CLI frameworks (Click, argparse).
When to use it

When you need to quickly create a CLI interface for an MCP server following best practices.

When not to use it

When you have a simple script that doesn't need full CLI features or when a GUI is more appropriate.

Security analysis

Safe
Quality score90/100

The skill generates CLI wrapper code; it does not instruct any destructive or exfiltration actions. It uses Bash only for testing and validation within the generated code, which is standard and safe.

Generate CLI Wrapper Code

This skill generates complete, production-ready CLI wrapper code for MCP servers.

When This Skill Activates

Use this skill when:

  • User wants to create a CLI wrapper for an MCP server
  • User requests wrapper code generation
  • User needs a Python or TypeScript wrapper
  • User asks to wrap MCP tools in a CLI
  • User wants to follow progressive disclosure patterns

What This Skill Does

  1. Reads MCP server analysis or configuration
  2. Selects appropriate template (Python/TypeScript)
  3. Generates complete wrapper code with:
    • PEP 723 header (Python) or package.json (TypeScript)
    • 4-level progressive disclosure help system
    • Function routing and argument parsing
    • Detail level enum support
    • Error handling and validation
    • Output format options (json|text|table)
  4. Creates FUNCTION_INFO and FUNCTION_EXAMPLES
  5. Tests basic functionality
  6. Validates code syntax

Usage

User: "Generate a Python wrapper for the github MCP"
User: "Create a CLI tool for the firecrawl server"
User: "Generate TypeScript wrapper for my calendar API"

Arguments

The skill accepts:

  • MCP server name (required)
  • Language preference (python|typescript)
  • Output path (optional)
  • Template style (standard|fastmcp|sdk)

Output

Generates a complete CLI wrapper file:

#!/usr/bin/env -S uv run
# /// script
# requires-python = ">=3.8"
# dependencies = ["click", "httpx", "rich", "python-dotenv"]
# ///

# Complete implementation with:
# - 4-level progressive disclosure
# - All tool functions
# - Detail level support
# - Error handling
# - Output formatting

Example Output

For GitHub MCP:

# Generated file: github-cli.py

# Test it
uv run github-cli.py --help          # Level 1: Quick help
uv run github-cli.py list            # Level 2: Function list
uv run github-cli.py info create_issue   # Level 2: Function details
uv run github-cli.py example create_issue  # Level 3: Examples
uv run github-cli.py create_issue --help   # Level 4: Complete reference

# Use it
uv run github-cli.py list_issues --repo=owner/repo
uv run github-cli.py create_issue --title="Bug" --body="Description"

Reference Implementations

The skill studies these reference wrappers:

  • /Users/bruno/cli-wrappers/exa.py - Example structure
  • /Users/bruno/cli-wrappers/github.py - GitHub wrapper
  • /Users/bruno/cli-wrappers/firecrawl.py - Firecrawl wrapper
  • /Users/bruno/cli-wrappers/CLAUDE.md - Development guidelines

Quality Assurance

Generated code is validated for:

  • Correct PEP 723 header syntax
  • All dependencies listed
  • Executable shebang
  • 4-level help completeness
  • Function routing correctness
  • Error handling coverage
  • Output format support
  • Syntax correctness

Agent Context

This skill runs in a forked context using the wrapper-generator agent, which specializes in:

  • Code generation from templates
  • Progressive disclosure implementation
  • CLI framework usage (Click, argparse)
  • MCP client integration
  • Following established patterns from ~/cli-wrappers/

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/generate-cli-wrapper-code-for-mcp-servers-mm5t8bdj/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/generate-cli-wrapper-code-for-mcp-servers-mm5t8bdj' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/generate-cli-wrapper-code-for-mcp-servers-mm5t8bdj/download' --output '.skill-downloads/generate-cli-wrapper-code-for-mcp-servers-mm5t8bdj/SKILL.md.part' && mv '.skill-downloads/generate-cli-wrapper-code-for-mcp-servers-mm5t8bdj/SKILL.md.part' '.skill-downloads/generate-cli-wrapper-code-for-mcp-servers-mm5t8bdj/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

test -f '.skill-downloads/generate-cli-wrapper-code-for-mcp-servers-mm5t8bdj/SKILL.md' && test -s '.skill-downloads/generate-cli-wrapper-code-for-mcp-servers-mm5t8bdj/SKILL.md' && mkdir -p '.claude/skills' && test ! -e '.claude/skills/generate-wrapper' && cp -R '.skill-downloads/generate-cli-wrapper-code-for-mcp-servers-mm5t8bdj' '.claude/skills/generate-wrapper'

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation
openskills install './.skill-downloads/generate-cli-wrapper-code-for-mcp-servers-mm5t8bdj'

openskills read 'generate-cli-wrapper-code-for-mcp-servers-mm5t8bdj'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/generate-cli-wrapper-code-for-mcp-servers-mm5t8bdj/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
