MCP Skill Generator

Generate reusable skills from any MCP server using mh CLI.

Prerequisites

•mh CLI must be installed. If not available, install with:

bash

curl -fsSL https://raw.githubusercontent.com/vaayne/mcphub/main/scripts/install.sh | sh

Workflow

1. Gather Input

Parameter	Required	Default	Example
URL	No	-	`https://mcp.exa.ai`
Config	No	-	`./mcp.json`
Transport	No	`http`	`http` or `sse`
Name	No	from URL or config	`exa-search`
Output	No	`./<name>/SKILL.md`	`./skills/exa-search/SKILL.md`

Notes:

•--url/-u and --config/-c are mutually exclusive
•Config mode uses the tool names returned by mh list, with JS-style name mapping and collision checks

2. Discover Tools

URL mode:

bash

mh list -u <url> -t <transport>

Stdio mode:

bash

mh list --stdio -- cmd args ...

Config mode:

bash

mh list -c <config>

3. Generate Skill

Read references/skill-template.md, fill placeholders: {skill-name}, {description}, {Title}, {url}, {transport}, {tool-count}, {tools-list}, {usage-block}, {notes-block}.

Usage blocks:

URL mode:

code

List tools: `mh list -u {url} -t {transport}`
Get tool details: `mh inspect -u {url} -t {transport} <tool-name>`
Invoke tool: `mh invoke -u {url} -t {transport} <tool-name> '{"param": "value"}'`

Config mode (use local config file name):

code

List tools: `mh list -c {config-file}`
Get tool details: `mh inspect -c {config-file} <tool-name>`
Invoke tool: `mh invoke -c {config-file} <tool-name> '{"param": "value"}'`

Notes blocks:

URL mode:

code

- Run `inspect` before invoking unfamiliar tools to get full parameter schema
- Timeout: 30s default, use `--timeout <seconds>` to adjust

Config mode:

code

- Run `inspect` before invoking unfamiliar tools to get full parameter schema
- Timeout: 30s default, use `--timeout <seconds>` to adjust

4. Write Output

Save to output path, create directories if needed.

If input is a config file, copy it into the generated skill folder as config.json and set {config-file} in the usage block to ./config.json, relative to the generated SKILL.md location.

Naming Guidelines

Name: Focus on capability, not source. Pattern: {source}-{capability} (kebab-case, 2-3 words)

URL	Tools	Good	Bad
`https://mcp.exa.ai`	webSearchExa, getCodeContextExa	`mcp-exa-search`	`exa`
`https://api.example.com/weather`	getWeather, getForecast	`mcp-weather-api`	`weather`

Description: {Action + capability}. Use when {conditions}. Triggers on "{phrase1}", "{phrase2}".

•Start with action verb (Search, Fetch, Get, Create, Analyze)
•Include 3-5 trigger phrases, mention service name, keep under 200 chars

Error Handling

Error	Action
Connection timeout	Verify URL, check network, increase `--timeout`
No tools returned	Server may require auth or have no tools
Transport mismatch	Try `http` first, fall back to `sse`
