Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00072 | $0.01646 |
| Opus 5 | $0.00036 | $0.00823 |
| Sonnet 5 | $0.00014 | $0.00329 |
| Haiku 4.5 | $0.00007 | $0.00165 |
Grade A, and why
mcp-to-skill-converter scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 206 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MCP to Skill Converter
Convert any MCP server into a Claude Skill with progressive disclosure pattern, reducing context usage by 90%+.
When to Use This Skill
- Converting MCP servers to skills for context efficiency
- Listing available MCP servers in a project
- Batch converting multiple MCP servers
- Creating skills from
.mcp.jsonconfiguration
Quick Commands
All commands run from project root where the plugin is installed.
List Available Servers
python ${PLUGIN_DIR}/skills/mcp-to-skill-converter/mcp_to_skill.py --list
Shows all MCP servers with compatibility status (stdio, http, and sse types are compatible).
Convert Single Server (auto-outputs to mcp-skills/)
python ${PLUGIN_DIR}/skills/mcp-to-skill-converter/mcp_to_skill.py --name <server-name>
Example:
python ${PLUGIN_DIR}/skills/mcp-to-skill-converter/mcp_to_skill.py --name github
# Outputs to: .claude/skills/mcp-skills/github/
# Automatically removes github from .mcp.json
# Updates mcp-skills/index.json
Convert All Compatible Servers
python ${PLUGIN_DIR}/skills/mcp-to-skill-converter/mcp_to_skill.py --all
# Converts all compatible servers (stdio, http, sse) to mcp-skills/
Custom Output Directory
python ${PLUGIN_DIR}/skills/mcp-to-skill-converter/mcp_to_skill.py --name github --output-dir /custom/path
Specify Custom .mcp.json
python ${PLUGIN_DIR}/skills/mcp-to-skill-converter/mcp_to_skill.py --mcp-json /path/to/.mcp.json --name github --output-dir ./skills
CLI Options
| Option | Description |
|---|---|
--list |

--name NAME |
Convert specific server by name |
--all |
Convert all compatible servers |
--output-dir PATH |
Output directory for generated skill(s) |
--mcp-json PATH |

What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
