Use 3GPP Scout in Claude

3GPP Scout gives Claude cited answers from 3GPP specifications (Rel-15 to Rel-20), meeting contributions (TDocs), meeting decisions and company positions. It works in claude.ai, Claude Desktop, the Claude mobile apps and Claude Code, and signs in with your Scout account.

At a glance

  • Server URL: https://api.3gppscout.com/mcp/
  • Sign-in: your Scout account (OAuth). The free Explorer plan includes 150 requests per UTC month.
  • Works in claude.ai, Claude Desktop, Claude mobile and Claude Code.
  • Purchases are not available inside Claude.

Connect in claude.ai or Claude Desktop

  1. Open Customize > Connectors (claude.ai/customize/connectors). In the desktop app, select Customize in the sidebar, then Connectors.
  2. If 3GPP Scout is listed in the directory, select Discover, search for "3GPP Scout", open it and select Connect to Claude.
  3. If it is not listed yet, select Add, then Add custom connector. Enter the name "3GPP Scout" and the URL https://api.3gppscout.com/mcp/, then select Continue. Keep the authentication options Claude marks as Detected, and select Add.
  4. Select Connect. A 3GPP Scout sign-in page opens. Sign in or create a free account, then approve access.
  5. Back in Claude, 3GPP Scout shows as Connected. It is available in your conversations on the web, desktop and mobile.

On Team and Enterprise plans an Owner adds the connector in Organization settings > Connectors, and each member then connects with their own Scout account.

Connect in Claude Code

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

Then run /mcp in Claude Code, choose 3gpp-scout and sign in in the browser window that opens. Agents that cannot open a browser can send a Scout API key instead, as the header Authorization: Bearer sk-... (create one in the dashboard).

What Claude can do with Scout

Scout has 17 tools. 14 only read; 3 change the topics you follow, and Claude asks you before it runs those.

Specifications Read only

  • search_specs: find where a behavior, message or value is defined, normative specs first
  • read_clause: read one clause with its citation
  • clause_history: which releases have a clause and which changed it
  • lookup_reference: a cause code, timer, information element or term by name or number
  • get_procedure: a whole signaling procedure: messages, fields, checks and result codes
  • find_conformance_tests: the test cases for one requirement clause

Meetings, TDocs and companies Read only

  • search_meeting_documents: TDocs by topic, with group, meeting, spec, company and date filters
  • find_meetings: meeting IDs by group and date
  • get_meeting_decisions: what a meeting agreed, approved, noted or rejected
  • get_tdoc: one TDoc with its quoted proposals
  • company_positions: who proposed, supported or opposed something, quoted from their TDocs

Followed topics

find_topics_to_follow, list_followed_topics and get_followed_topic_updates only read. follow_topic saves a followed topic to your Scout account after you confirm the targets; update_followed_topic changes one; unfollow_topic deletes one.

Email digests are sent only when your follow settings enable them.

Try these prompts

  • What does TS 24.501 say the UE does when registration is rejected with 5GMM cause #7? Quote the clause.
  • What did RAN1 #126 agree on NTN? Give the TDoc numbers.
  • Which companies supported or opposed the RedCap eDRX proposals in RAN2, and what did they say?
  • Read the RRC reconfiguration procedure in TS 38.331 Rel-18, clause 5.3.5.3, and tell me what changed in Rel-19.
  • Help me follow changes to TS 38.331. Show me the targets before you save anything.

Usage and your account

Each tool call counts as one request against your Scout plan, the same as the REST API. When you reach the monthly limit, Scout says when it resets; your usage is on the usage page. Manage followed topics on the Followed topics page.

Answers quote short excerpts with spec number, version and clause, and link to the official 3GPP document, which governs.

Data and privacy

When Claude calls a Scout tool, Scout receives the tool name, its arguments and your signed-in Scout account. Scout does not request the rest of your conversation, your Claude memory or your files. We use request records to meter usage and fix failures, and we do not use them to train models, sell them or build advertising profiles.

Details: Privacy Policy, section "API and MCP Requests".

Troubleshooting

Sign-in page does not open, or Claude says authorization failed

In Customize > Connectors, open 3GPP Scout, select Disconnect, then Connect again.

Claude says it cannot reach the server

Check the URL is exactly https://api.3gppscout.com/mcp/.

A tool says you have used this month's requests

The limit resets on the date in the message. Your usage is on the usage page.
