## What it does

The server exposes nine tools for working with Regulations.gov. An agent can inspect rulemaking dockets, review their documents and comments, check comment periods, and examine whether materials are ready for the next step.

Claude Code can use either a hosted HTTP connection or a local process started with `uvx regulationsgov-mcp`. The local setup requires `REGULATIONS_GOV_API_KEY`; without that variable, this installation path will not work. The hosted endpoint is `https://regulations-gov.1102tools.com/mcp`.

The installation commands also cover Codex, Cursor, GitHub Copilot, Gemini CLI, and the other listed platforms. Once connected, the agent can query Regulations.gov while handling a task instead of relying on a separate browser session.

## Requirements
- Needs: Python and uv (commands run via uvx)
- Remote server: `https://regulations-gov.1102tools.com/mcp`
- Environment variables: `REGULATIONS_GOV_API_KEY` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## Install

### Claude Code (native platform)

1. **Platform CLI: remote server**
```bash
claude mcp add --transport http regulations-gov-mcp https://regulations-gov.1102tools.com/mcp
```

2. **Platform CLI**
```bash
claude mcp add --env REGULATIONS_GOV_API_KEY=<REGULATIONS_GOV_API_KEY> --transport stdio regulations-gov-mcp -- uvx regulationsgov-mcp
```
Replace <…> with your own values. uvx runs the command named after the package; if the README names another one, use uvx --from regulationsgov-mcp <command>

### Codex

1. **Platform CLI: remote server**
```bash
codex mcp add regulations-gov-mcp --url https://regulations-gov.1102tools.com/mcp
```

2. **Platform CLI**
```bash
codex mcp add regulations-gov-mcp --env REGULATIONS_GOV_API_KEY=<REGULATIONS_GOV_API_KEY> -- uvx regulationsgov-mcp
```
Replace <…> with your own values. uvx runs the command named after the package; if the README names another one, use uvx --from regulationsgov-mcp <command>

### Cursor

**Config file**
File `.cursor/mcp.json`:
```json
{
    "mcpServers": {
        "regulations-gov-mcp": {
            "url": "https://regulations-gov.1102tools.com/mcp"
        }
    }
}
```
File `.cursor/mcp.json`:
```json
{
    "mcpServers": {
        "regulations-gov-mcp": {
            "command": "uvx",
            "args": [
                "regulationsgov-mcp"
            ],
            "env": {
                "REGULATIONS_GOV_API_KEY": "<REGULATIONS_GOV_API_KEY>"
            }
        }
    }
}
```
Replace <…> with your own values. uvx runs the command named after the package; if the README names another one, use uvx --from regulationsgov-mcp <command>

### GitHub Copilot

**Config file**
File `.vscode/mcp.json`:
```json
{
    "servers": {
        "regulations-gov-mcp": {
            "type": "http",
            "url": "https://regulations-gov.1102tools.com/mcp"
        }
    }
}
```
File `.vscode/mcp.json`:
```json
{
    "servers": {
        "regulations-gov-mcp": {
            "type": "stdio",
            "command": "uvx",
            "args": [
                "regulationsgov-mcp"
            ],
            "env": {
                "REGULATIONS_GOV_API_KEY": "<REGULATIONS_GOV_API_KEY>"
            }
        }
    }
}
```
Replace <…> with your own values. uvx runs the command named after the package; if the README names another one, use uvx --from regulationsgov-mcp <command>

### Gemini CLI

1. **Platform CLI: remote server**
```bash
gemini mcp add -t http regulations-gov-mcp https://regulations-gov.1102tools.com/mcp
```

2. **Platform CLI**
```bash
gemini mcp add -e REGULATIONS_GOV_API_KEY=<REGULATIONS_GOV_API_KEY> regulations-gov-mcp uvx regulationsgov-mcp
```
Replace <…> with your own values. uvx runs the command named after the package; if the README names another one, use uvx --from regulationsgov-mcp <command>
