sync-list

A command that lists the Model Context Protocol (MCP) servers configured in Claude Code, including how each server connects and where its setting came from.

In plain words
What is it for?
Use it to group servers by STDIO, HTTP, or SSE connection, see whether settings came from a configuration file or plugin, and spot servers needing OAuth sign-in.
Why use it?
It gives you one readable view of the servers Claude Code can use, so you do not have to inspect configuration files manually.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.

Security

Grade A, and why

sync-list 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 3d 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.

What it actually says

List all MCP servers that Claude Code knows about.

Execution Flow

  1. Run: npx sync-agents-settings list

  2. Present the output to the user in a readable format:

    • Group servers by transport type (STDIO, HTTP, SSE)
    • Show the source of each server (config = from ~/.claude.json, plugin = from Claude plugin)
    • Highlight any servers that require OAuth authentication

Error Handling

  • If npx fails: suggest npm install -g sync-agents-settings as fallback.
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.
