## What it does

A network policy in Celigo is a named pair of IP lists kept per environment. One list admits addresses, the other refuses them outright. The policy guards nothing until you assign it somewhere. The skill walks through how a policy decides: deny beats allow, and an empty allow list lets through everything the deny list doesn't name.

There are four places a policy can be assigned: an MCP server, an account API token, workspace-user sign-in, and end-user sign-in. Assigning to a token or to sign-in happens only in the integrator.io UI, while MCP servers can be handled through the CLI or MCP tools. Only the account owner and administrators manage policies, and the feature has to be enabled on the account. Each environment keeps its own library, so a policy is visible and assignable only where it was created.

Before you assign or edit a policy, check whether it covers your own access — the token your CLI profile, script or MCP client signs in with, or workspace-user sign-in. If it does, you can lock yourself out. A patch changes only the fields you name; a full replace empties every list left out of the request. Deleting a policy that is still assigned is refused unless forced, and forcing it lifts every restriction the policy imposed.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add celigo/ai --skill managing-network-policies -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/managing-network-policies/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/managing-network-policies/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add celigo/ai --skill managing-network-policies -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/managing-network-policies/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add celigo/ai --skill managing-network-policies -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/managing-network-policies/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install celigo/ai managing-network-policies
```

2. **Manually: put the files in place**
- File: `.github/skills/managing-network-policies/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add celigo/ai --skill managing-network-policies -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/celigo/ai --path skills/managing-network-policies
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/managing-network-policies/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add celigo/ai --skill managing-network-policies -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/celigo/ai/tree/HEAD/skills/managing-network-policies/SKILL.md

## When to use it
- limit one MCP server to known networks
- attach a policy to a service token used by CI or a partner script
- refuse a few known-bad addresses and admit the rest
- change a range everywhere a policy is assigned
- work out which policy refused a caller

## Example prompts
- List the network policies in this environment and show where each one is assigned
- Assign the Corporate VPN egress policy to this MCP server and check my own token won't be cut off
- Remove 10.0.0.0/8 from the deny list without touching the other entries

description: Manage Celigo network policies -- named IP allow and deny lists that restrict where API tokens, MCP servers, and workspace-user or end-user sign-in may connect from. Covers how a policy decides, the four places one is assigned, patch versus full-replace edits, deleting a policy that is still assigned, and avoiding locking yourself out. Use when restricting an MCP server, a token, or sign-in to known networks, editing or deleting a policy, or checking whether a policy explains a refused caller.

# Managing Network Policies

A network policy is a **named pair of IP lists** -- addresses allowed to connect and addresses always refused -- kept per environment and assigned wherever access should be limited by source address. One policy can guard many things, and a policy guards nothing until it is assigned. Concerns when managing network policies:

- **What a policy decides** -- deny beats allow, and an empty allow list admits everything the deny list doesn't name
- **Where it applies** -- an MCP server, an account API token, workspace-user sign-in, or end-user sign-in
- **Editing safely** -- a patch changes only what you name; a full replace empties every list it leaves out
- **Deleting** -- an assigned policy is refused unless forced, and forcing lifts every restriction it imposed
- **Lockout** -- a policy on the token or sign-in you are using applies to you

Only the account owner and administrators manage network policies, and the feature must be enabled for the account. Each environment (production, a sandbox) keeps its own library: a policy is visible and assignable only in the environment that created it.

## How to Run the Steps

This skill names each step by what it reads or changes; the exact calls depend on how you reach the account. Read the one reference that matches your tools -- both follow the step numbers of How to Manage Network Policies below:

- **Celigo MCP tools** -- [references/mcp.md](references/mcp.md). The deployed server has no network-policy tools: it can only assign or clear a policy on an MCP server, so most steps go to the CLI or the integrator.io UI.
- **The `celigo` CLI** -- [references/cli.md](references/cli.md)

Assigning a policy to an API token or to sign-in happens only in the integrator.io UI, on either surface.
