About

Connects to the public Federal Register API. You can search proposed rules, final rules, notices and presidential documents, fetch full document details, count documents by agency, type or time period, and check pre-publication public inspection filings. It also finds open comment periods and traces the rulemaking history of FAR and DFARS cases.

Runs as a hosted streamable HTTP endpoint or as a local Python package started with uvx (federal-register-mcp). No sign-in or API key is needed.

What you can do

  • Search proposed rules, final rules, notices and presidential documents
  • Fetch full details for one or many documents by number
  • Count documents by agency, type, topic or time bucket
  • List open comment periods sorted by deadline
  • Trace FAR and DFARS case history from proposal to final rule
  • Read pre-publication public inspection documents
  • Look up agency slugs for filtering

Set up

Every client connects to federal-register.1102tools.com. Pick yours; the page remembers your choice.

Claude Code

  1. Run this in a terminal, in your project folder:
claude mcp add --transport http federal-register https://federal-register.1102tools.com/mcp
  1. Start Claude Code and type /mcp. federal-register should show as connected.

Add --scope user to make it available in every project, not just this one.

Claude Desktop

  1. Open Customize → Connectors, click + Add, then Add custom connector.
  2. Name it Federal Register and paste this URL:
https://federal-register.1102tools.com/mcp
  1. Click Add. Its tools appear in the chat’s tools menu.

Claude Desktop’s JSON config file only starts local servers. Remote servers go through Connectors, and connectors you add on claude.ai show up here too.

claude.ai

  1. Open the connector form on claude.ai. This button fills in the name and URL for you:
  1. Check that the URL reads https://federal-register.1102tools.com/mcp and click Add.
  2. Turn it on in a chat from the tools menu.

Free plans allow one custom connector. On Team and Enterprise plans an owner adds it under Organization settings → Connectors.

ChatGPT

  1. On chatgpt.com, go to Plugins, select +, then Add custom MCP server.
  2. Enter a name for the server.
  3. Under Connection, paste https://federal-register.1102tools.com/mcp as the server URL, then for authentication choose No authentication.
  4. Check I understand and want to continue, then select Create as a plugin.

Whether you can add a custom MCP server depends on your ChatGPT plan and your workspace permissions (in Business workspaces, admins and owners can).

Cursor

Or add it by hand to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (this project):

mcp.json
{
  "mcpServers": {
    "federal-register": {
      "url": "https://federal-register.1102tools.com/mcp"
    }
  }
}

VS Code

Or from a terminal:

code --add-mcp '{"name":"federal-register","type":"http","url":"https://federal-register.1102tools.com/mcp"}'

Or commit it to the repo in .vscode/mcp.json:

.vscode/mcp.json
{
  "servers": {
    "federal-register": {
      "type": "http",
      "url": "https://federal-register.1102tools.com/mcp"
    }
  }
}

Devin Desktop

  1. Add it to ~/.config/devin/mcp_config.json (macOS and Linux) or %APPDATA%\devin\mcp_config.json (Windows):
mcp_config.json
{
  "mcpServers": {
    "federal-register": {
      "serverUrl": "https://federal-register.1102tools.com/mcp"
    }
  }
}
  1. Refresh the MCP server list in Cascade.

Devin Desktop is the new name for Windsurf. It reads serverUrl (or url) for remote servers.

Codex

codex mcp add federal-register --url https://federal-register.1102tools.com/mcp

Or edit ~/.codex/config.toml directly:

config.toml
[mcp_servers.federal-register]
url = "https://federal-register.1102tools.com/mcp"

Gemini CLI

gemini mcp add --transport http federal-register https://federal-register.1102tools.com/mcp

This adds it to the current project. Add -s user to use it everywhere.

Any client

Most clients accept this shape. Some name the URL field differently: serverUrl in Devin Desktop, httpUrl in Gemini CLI’s settings file.

{
  "mcpServers": {
    "federal-register": {
      "type": "http",
      "url": "https://federal-register.1102tools.com/mcp"
    }
  }
}

Zed puts servers under context_servers in its settings. Cline needs "type": "streamableHttp", or it assumes SSE.

Client only starts local servers? Bridge it with npx -y mcp-remote https://federal-register.1102tools.com/mcp.

Embed

Show Federal Register in a README or on your site. Each embed links to this page, uses the server’s own URL, and sets no cookies. How embeds work

The card, the iframe and the JSON are in English. Add ?lang=it, fr, de or es to their address for another language.

[![Federal Register on mcp.tc](https://mcp.tc/i/federal-register/badge.svg)](https://mcp.tc/i/federal-register)
HTML
<a href="https://mcp.tc/i/federal-register"><img src="https://mcp.tc/i/federal-register/badge.svg" alt="Federal Register on mcp.tc" height="20"></a>

It follows the reader’s light or dark mode. Add ?theme=light or ?theme=dark to fix it, or ?style=compact to show the mark without the word.

Website card

HTML
<script src="https://mcp.tc/w/federal-register.js" async></script>

The card appears where the tag is. Add data-theme="dark" or data-size="compact" to the tag to change it. The file holds everything it needs, so it makes no other requests and sets no cookies.

iframe

HTML
<iframe src="https://mcp.tc/embed/federal-register" title="Federal Register on mcp.tc" width="420" height="200" loading="lazy" allow="clipboard-write" style="border:0;border-radius:8px;max-width:100%"></iframe>

Use it on pages that don’t allow scripts. Add ?theme=light or ?theme=dark to the address to fix the colors.

JSON

The listing as data for your own pages and tools: name, tagline, the server’s own URL, tools and the “Add to” links. Any site can read it (CORS is open).

What each field means

AI prompt

Paste this into an AI coding assistant, such as Claude Code or Cursor, and it adds the Federal Register card to your site.

Markdown
Add the mcp.tc card for Federal Register, an MCP server, to my website. It is one static script: no build step, no package to install, no cookies.

Put this tag where the card should appear. The card renders right before it:

```html
<script src="https://mcp.tc/w/federal-register.js" async></script>
```

To show the card somewhere else, put this placeholder there and load the same script once, for example before `</body>`. Keep the link inside: visitors without JavaScript see it.

```html
<div data-mcptc="federal-register"><a href="https://mcp.tc/i/federal-register">Federal Register on mcp.tc</a></div>
```

Options:
- `data-theme="light"` or `"dark"` on the tag or the placeholder fixes the colors. Without it, the card follows the visitor’s light or dark mode.
- `data-size="compact"` gives a smaller card without the tagline.
- The CSS variable `--mcptc-max-width` on the placeholder or a parent sets the width (default `520px`).
- `?lang=` on the script URL sets the card’s language: `en`, `it`, `fr`, `de` or `es`.

If the site has a Content Security Policy, allow `script-src https://mcp.tc` and `img-src data:` (the icon is inline).

For a README or other Markdown docs, use the badge instead:

```markdown
[![Federal Register on mcp.tc](https://mcp.tc/i/federal-register/badge.svg)](https://mcp.tc/i/federal-register)

FAQ

Can I paste mcp.tc/i/federal-register into my MCP client?

No. mcp.tc links are pages, not server addresses. Connect with https://federal-register.1102tools.com/mcp, so your client talks to Federal Register directly. The quick link is for sharing: it opens this page, with setup steps for every client.

Does Federal Register need an API key or a sign-in?

No. Federal Register doesn’t ask for an account or key.

Is Federal Register a remote or a local server?

Remote. 1102tools hosts it at https://federal-register.1102tools.com/mcp, and it speaks Streamable HTTP. There’s nothing to install.

What can Federal Register do?

It has 8 tools, including search_documents, get_document and get_documents_batch. You can search proposed rules, final rules, notices and presidential documents, fetch full details for one or many documents by number and count documents by agency, type, topic or time bucket.

Which clients can use it?

Any client that supports remote MCP servers: Claude Code, Claude Desktop, claude.ai, ChatGPT, Cursor, VS Code, Devin Desktop, Codex, Gemini CLI, Zed and others. The setup steps cover each one.

Does mcp.tc track changes to Federal Register?

Yes. Federal Register’s History tab shows each change we find to its tools, down to descriptions and parameters, plus new versions and edits by its owner. Follow the listing to get an email when it changes.

Who wrote this page?

mcp.tc’s robot read Federal Register’s own metadata (its MCP handshake, tool list and public pages), and an AI model drafted the text from it. A person reviews anything the checks can’t confirm. The text can still be wrong, so if you spot a mistake, use Report this listing on this page.

mcp.tc isn’t affiliated with 1102tools. This page was built from Federal Register’s public metadata, last checked on 6 Nov 2026, and an AI model wrote the description, so it can be wrong. Names and marks belong to their owners. Something off? Report this listing.
