connect

connect is a skill for Claude Code, Codex from activeing123/mcptoon. It costs 35 tokens per session (699 once invoked), scanned A, original, Apache-2.0.

A setup skill for mcptoon, which keeps one list of Model Context Protocol (MCP) servers and synchronizes it across AI coding tools.

In plain words
What is it for?
Use it to discover, add, validate, and synchronize local or remote MCP servers across supported coding agents.
Why use it?
It removes the need to configure the same external tools separately in each agent or editor.

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

connect 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 2d 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 — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Connect agents to MCP servers with mcptoon

mcptoon keeps one config (~/.mcptoon/config.json) as the single source of truth for every MCP server an agent may use. It syncs that config into Claude Desktop, Claude Code, Cursor, Codex, Cline, Windsurf and VS Code, and can expose all servers through one stdio gateway (mcptoon serve).

First move: look before you change anything

mcptoon list            # what servers are configured right now
mcptoon doctor          # config syntax + connectivity diagnosis

If doctor reports problems, fix those before adding anything new.

Add servers

mcptoon discover                  # scan + probe locally installed MCP servers
mcptoon discover --write          # and write what was found into config
mcptoon add <name> --help         # see add options for stdio/http servers
mcptoon install <name> --npm @scope/pkg   # from npm
mcptoon install <name> --pip pkg          # from pip
mcptoon install <name> --url https://host/mcp   # streamable-http / sse

After editing ~/.mcptoon/config.json by hand, validate with mcptoon doctor.

Sync one config to every agent

mcptoon sync              # write config into all detected agents
mcptoon sync --dry        # preview only
mcptoon sync --agent claude   # one agent only

Instead of registering N servers in an agent, register ONE:

{ "mcpServers": { "mcptoon": { "command": "mcptoon", "args": ["serve"] } } }

mcptoon serve speaks MCP over stdio and forwards to every configured server. Benefits: one entry in the agent config, tool lists stay compact, and Plugin skills appear as MCP prompts automatically.

Token efficiency flags

Tool manifests can be huge. When calling mcptoon from a terminal, keep output small on purpose:

mcptoon manifest --toon        # standard TOON format (30-60% saved)
mcptoon manifest --slim        # ultra-compact schemas (93% saved)
mcptoon manifest --compact     # names only (99.8% saved)
mcptoon search <query>         # find a tool without dumping the whole manifest
mcptoon inspect <server> <tool>   # full schema for exactly one tool

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.
