iron-proxy-gateway

iron-proxy-gateway is a skill for Claude Code from nanocoai/nanoclaw. It costs 40 tokens per session (492 once invoked), scanned A, original, MIT.

A gateway for connecting external accounts and APIs, including GitHub through the gh command-line tool. It sends requests through a proxy and can require human approval before adding credentials.

In plain words
What is it for?
Use it to connect an account, send approved requests to an external service, and investigate whether a failure comes from access rules, approval, credentials, or the service itself.
Why use it?
It separates API access and credentials from the coding session, while making blocked requests easier to diagnose without exposing secret tokens.

About the project

NanoClaw is an AI assistant that runs agents inside separate Linux containers, isolating their files and execution environments. People use it to connect agents to messaging services and run assistants with memory and scheduled jobs. The catalogue contains skills and instructions for extending or operating NanoClaw.

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

iron-proxy-gateway 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 23d 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

Iron Proxy gateway

Your outbound HTTP and HTTPS requests pass through your session's Iron Proxy. A policy-selected credential request waits for human approval before the proxy inserts a credential. You receive only a useless placeholder.

Policy failures

A bare 403 does not prove which layer rejected the request. It may be the destination rule, credential grant, human approval, or upstream API. Respect the block, report the hostname and observed error, and request a host-side check instead of guessing that credentials were never injected.

Connect an account

Run the shared command for the API hostname requested by the user:

ncl groups connect --host <API hostname>

Return the exact connect_url and describe its action. An operator_console handoff requires the operator to configure the credential, grant, and destination in the gateway; it is not an OAuth link. Do not invent a connection flow when the result is unsupported. The command does not grant access or change policy.

Use the user's requested CLI or a direct HTTP client. Do not add an MCP server merely to connect an account. Clients requiring local authentication may use gateway-managed as a non-secret placeholder (for example GH_TOKEN for gh). Never use a real token in the client. Never run a local login to store credentials.

Request approval and account connection are separate. A 401 is not proof that injection did not happen: the stored token may itself be invalid. Report the observed result, follow the shared handoff, and verify with a credentialed request after the operator completes configuration. Never claim connected before success.

Rules

  • Never ask for, print, or store a raw API key or OAuth token.
  • Never bypass the configured proxy or its CA validation.
  • Never treat a pending approval as granted.
  • Never claim a blocked destination is connected.
  • Treat proxy errors as policy or operator-configuration errors, not as permission to weaken TLS.
Files

What ships with it

1 file 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.
