Overview

Description from the maker (original English)

Hosted 3GPP MCP server for Rel-15–20 TS/TR search. Index stays current.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Search & AI memory

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "scout": {
      "type": "http",
      "url": "https://api.3gppscout.com/mcp/"
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save
  4. If it asks you to sign in, sign in with the maker

Common questions

Is 3GPP Scout safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.2.1) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Hosted 3GPP MCP Server

3GPP Scout is a hosted 3GPP MCP server. It makes 3GPP technical specifications (TS and TR) searchable from Cursor, Claude, Codex, and other MCP clients: 5G NR, LTE, RAN, and 5G core, Rel-15 through Rel-20.

You do not download the 3GPP FTP archive, parse Word files, or run a local SQLite index. Connect to the remote Model Context Protocol endpoint and search.

MCP endpoint: https://api.3gppscout.com/mcp/ (Streamable HTTP, OAuth 2.1)

This repository is the public listing and integration page for the 3GPP Scout MCP Server. There is nothing here to go run or npx. If you want a 3GPP MCP server without self-hosting, this is that product. See License and the hosted service.

Why a hosted 3GPP MCP

3GPP specifications are hard for LLMs to use from training data alone. There are thousands of TS/TR documents. A single spec such as TS 38.331 (NR RRC) or TS 23.501 (5G system architecture) can run hundreds of pages. Releases diverge. Tables and figures carry the protocol.

A self-hosted 3GPP MCP typically means: scrape the 3GPP archive, convert .docx, build a local database, and keep it current yourself. Scout runs that index as a service. New and revised 3GPP specs are ingested into the live search index as 3GPP publishes them.

The production corpus is Rel-15 through Rel-20 (8,700+ document versions, 1.3M+ sections). It is not a Rel-15 + Rel-19 subset.

What you can search

Specifications. Semantic search over the published TS/TR set, including:

  • 5G NR / RAN: 38-series (RRC, NG-RAN, NR overall description)
  • 5G system and core: 23-series architecture, 24-series NAS, 29-series HTTP/2 service-based interfaces, 33-series security
  • LTE / EPS: 36-series and related SAE specs
  • Charging, OAM, and the rest of the TS/TR catalog in those releases, not only radio

Filter by release (Rel-18, Rel-19, ...), document number (38.331, 23.501, 36.300), series, TS vs TR, or section. Image search covers figures, diagrams, and tables extracted from the specs.

Meeting documents and decisions. Search and read TDocs (meeting contributions, change requests, liaison statements) with status and quoted proposals, list meetings and what each one agreed, approved, noted or rejected, and summarize which companies argued for or against a proposal. The TDoc catalog currently covers RAN1, RAN2, RAN3, RAN4 and SA2, and grows as meetings are processed. The skill guide below lists the current coverage.

Supporting sources. IETF RFC passages that 3GPP specs depend on, with the 3GPP clauses that cite them, and telecom industry news.

Results carry citations: specification number, version, release and section for spec text, and TDoc number and meeting for contributions.

Citations from the hosted chat app link to the specification's folder on the 3GPP FTP archive, not to a sentence-level PDF deep-link.

Connect an agent (Cursor, Claude, Codex)

Official registry name: com.3gppscout/scout

Cursor

Merge into .cursor/mcp.json:

{

"mcpServers": { "3gpp-scout": { "url": "https://api.3gppscout.com/mcp/" } } }

Enable 3gpp-scout under Cursor Settings > Tools & MCP. The first tool call opens a browser for OAuth. Do not put a Scout API key in the MCP config.

Claude Code
claude mcp add --transport http --scope user 3gpp-scout https://api.3gppscout.com/mcp/

Then /mcp and connect 3gpp-scout.

ChatGPT plugin directory

Install 3GPP Scout from the ChatGPT plugin directory. It signs in with your Scout account and works in ChatGPT and Codex.

Codex and ChatGPT desktop plugin
codex plugin marketplace add carrotlabsai/3gpp-scout-mcp

codex plugin add 3gpp-scout@3gpp-scout

In the ChatGPT desktop app, open Plugins, add the plugin marketplace carrotlabsai/3gpp-scout-mcp, choose 3GPP Scout and install. Sign in with your Scout account when asked. The plugin bundles the hosted MCP server and a short skill; it lives in plugins/3gpp-scout.

OpenAI Codex (MCP only)
codex mcp add 3gpp-scout --url https://api.3gppscout.com/mcp/

codex mcp login 3gpp-scout

Verify

Call list_documents_documents_get with doc_number=38.331 and release=Rel-19. You should see indexed versions of TS 38.331. Do not list the entire corpus as a health check.

Setup prompt for agents: api.3gppscout.com/agent-setup/prompt.md

MCP tools

These are the tools the live server lists today. Names are the exact strings your client sees.

GroupTools

Follow topics (signed-in user)find_topics_to_follow, list_followed_topics, get_followed_topic_updates, follow_topic, update_followed_topic, unfollow_topic
Private previewcompare_proposal, get_proposal_comparison, follow_patent

Search and read tools are read-only. follow_topic, update_followed_topic, unfollow_topic and follow_patent change the signed-in user's Scout account, and fetch_tdoc may download a public TDoc into Scout's catalog. Tool names and parameters can change; the skill guide is the current reference.
