  "markdown": "# Hosted 3GPP MCP Server\n\n**3GPP Scout** is a [hosted 3GPP MCP server](https://3gppscout.com/mcp/?src=github). 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.\n\nYou 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.\n\n**MCP endpoint:** [`https://api.3gppscout.com/mcp/`](https://api.3gppscout.com/mcp/) (Streamable HTTP, OAuth 2.1)\n\nThis repository is the **public listing and integration page** for the 3GPP Scout MCP Server. The hosted service is proprietary. There is nothing here to `go run` or `npx`. If you want a 3GPP MCP server without self-hosting, this is that product.\n\n## Why a hosted 3GPP MCP\n\n3GPP 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.\n\nA 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.\n\nThe production corpus is **Rel-15 through Rel-20** (8,700+ document versions, 1.3M+ sections). It is not a Rel-15 + Rel-19 subset.\n\n## What you can search\n\nSemantic search over the published TS/TR set, including:\n\n- **5G NR / RAN:** 38-series (RRC, NG-RAN, NR overall description)\n- **5G system and core:** 23-series architecture, 24-series NAS, 29-series HTTP/2 service-based interfaces, 33-series security\n- **LTE / EPS:** 36-series and related SAE specs\n- **Charging, OAM, and the rest of the TS/TR catalog** in those releases, not only radio\n\nFilter 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.\n\nCitations from the hosted chat app link to the specification's folder on the 3GPP FTP archive, not to a sentence-level PDF deep-link.\n\n## Connect an agent (Cursor, Claude, Codex)\n\nOfficial registry name: [`com.3gppscout/scout`](https://registry.modelcontextprotocol.io/v0.1/servers?search=com.3gppscout/scout)\n\n### Cursor\n\nMerge into `.cursor/mcp.json`:\n\n```json\n{\n  \"mcpServers\": {\n    \"3gpp-scout\": {\n      \"url\": \"https://api.3gppscout.com/mcp/\"\n    }\n  }\n}\n```\n\nEnable **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.\n\n### Claude Code\n\n```bash\nclaude mcp add --transport http --scope user 3gpp-scout https://api.3gppscout.com/mcp/\n```\n\nThen `/mcp` and connect `3gpp-scout`.\n\n### OpenAI Codex\n\n```bash\ncodex mcp add 3gpp-scout --url https://api.3gppscout.com/mcp/\ncodex mcp login 3gpp-scout\n```\n\n### Verify\n\nCall `list_documents` 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.\n\nSetup prompt for agents: [api.3gppscout.com/agent-setup/prompt.md](https://api.3gppscout.com/agent-setup/prompt.md)\n\n## MCP tools\n\n| Tool | Use |\n|---|---|\n| `search_text` | Semantic search over specification text (primary) |\n| `search_images` | Figures, diagrams, and tables |\n| `search_combined` | Text and images in one request |\n| `list_documents` / `get_document` | Browse indexed TS/TR metadata |\n| `get_sections` / `list_sections` | Pull section body or TOC |\n| `get_image` | Fetch an extracted figure |\n\nFull agent skill (parameters, filters, workflows): [api.3gppscout.com/skill.md](https://api.3gppscout.com/skill.md). ClawHub listing: [chriscarrotlabs/3gpp-scout](https://clawhub.ai/chriscarrotlabs/3gpp-scout).\n\nREST with an API key (same corpus): [api.3gppscout.com/docs](https://api.3gppscout.com/docs)\n\n## FAQ\n\n**Is there a hosted 3GPP MCP server?**\nYes. 3GPP Scout at `https://api.3gppscout.com/mcp/`. Product page: [3gppscout.com/mcp](https://3gppscout.com/mcp/?src=github).\n\n**Do I need to self-host an MCP server for 3GPP specs?**\nNo. Scout is a remote MCP server operated by [Carrot Labs](https://carrotlabs.ai).\n\n**How do I give Cursor or Claude access to 3GPP specifications?**\nAdd the Streamable HTTP URL above. OAuth on first use. No local 3GPP MCP install.\n\n**Which 3GPP releases?**\nRel-15 through Rel-20, the published TS/TR set. The index stays current as 3GPP publishes.\n\n**Is this an official 3GPP or ETSI product?**\nNo. 3GPP Scout is independent. It is not affiliated with, endorsed by, or a partner of 3GPP or ETSI.\n\n## Pricing\n\nExplorer includes 150 MCP/API requests per UTC calendar month. Founding Engineer is $8/month for 1,000. Hosted chat at [app.3gppscout.com](https://app.3gppscout.com) uses separate prepaid credits.\n\nSign up: [dashboard.3gppscout.com](https://dashboard.3gppscout.com)\n\n## This repository\n\n| File | What it is |\n|---|---|\n| `README.md` | Integration and discovery (this page) |\n| `server.json` | Public MCP Registry metadata (remote server only) |\n| `SKILL.md` | Short agent skill that points at the hosted server |\n| `llms.txt` | Same facts in agent-readable form |\n\n`server.json` is discovery metadata. It does not contain credentials, prompts, or the search implementation. Do not open issues asking for the private monorepo or a self-host package. That is not what this repo is.\n\n## Links\n\n- Product: [3gppscout.com](https://3gppscout.com/?src=github)\n- Hosted MCP page: [3gppscout.com/mcp](https://3gppscout.com/mcp/?src=github)\n- Chat: [app.3gppscout.com](https://app.3gppscout.com)\n- Contact: [contact@3gppscout.com](mailto:contact@3gppscout.com)\n- Terms: [3gppscout.com/terms](https://3gppscout.com/terms.html)\n- Privacy: [3gppscout.com/privacy](https://3gppscout.com/privacy.html)\n",
