A configuration synchronizer that keeps MCP server settings and enabled states aligned across OpenCode, Claude Code, Codex, and a repository file using one shared source.

Use it after changing the shared MCP server list, when tool configurations have drifted, or when you need to enforce one setup across a repository.

It removes differences between the MCP settings used by different coding tools. Changes made in one canonical list can be applied consistently elsewhere.

Token cost

What it costs to keep this loaded

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	$0.00083	$0.02762
Opus 5.5	$0.00033	$0.01105
Sonnet 5.5	$0.00017	$0.00552
Haiku 4.5	$0.00008	$0.00276

Security

Grade B, and why

mcp-sync scanned grade B with 1 finding 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 yesterday.

The scan reads SKILL.md. This mod also ships 7 executable files (scripts/mcp_stdio.py, scripts/patch_dsh_mcp_panel.py, scripts/sync_dsh_connector.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Files

What ships with it

8 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.

Changes

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.
