 ### AI Tools & Skills
 
 - [Raven MCP](https://raven.stellar.buzz) - The official hosted MCP server for the Stellar ecosystem. Exposes `search` (Stellar docs + ecosystem discovery) and `execute` (queries against live ecosystem data) to any AI agent. Connect it directly: `claude mcp add --transport http stellar-raven "https://raven.stellar.buzz/mcp"`. Replaces the retired Stella assistant. See [Building with AI](./building-with-ai/README.md#raven--stellar-mcp-server-for-ai-agents).
-- [Stellar Skills Marketplace](https://skills.stellar.org/) - Official marketplace for browsing Stellar agent skills: Soroban, wallets, assets, RPC, x402 payments, ZK proofs, plus community skills (OpenZeppelin, DeFindex, Soroswap, Trustless Work).
-- [Stellar Dev Skill](https://github.com/stellar/stellar-dev-skill) - AI skill covering Soroban, Stellar SDK, RPC, wallets, ZK proofs, and ecosystem. Install via `/plugin install stellar-dev@stellar-dev` in Claude Code.

 - [LumenLoop Skills](https://github.com/lumenloop/lumenloop-skills) - Eight agent skills for ecosystem research (sector landscapes, project due diligence, SCF submission radar), powered by LumenLoop's free read-only MCP server. Works with any MCP client.
 - [stellar-build](https://github.com/kaankacar/stellar-build) - One-command install of 46 skills covering the full journey from idea to mainnet deploy and SCF grant submission, with six DevRel-persona agents.
 - [Stellar AI Guide](https://github.com/kaankacar/stellar-ai-guide) - Monorepo of regional AI developer guides (Mexico, Brazil, template for new countries): country-agnostic Claude Code setup, free AI tooling, and starter prompts, plus per-country anchor and payment-rail docs.

 A remote Model Context Protocol (MCP) server that gives AI agents unified access to Stellar documentation and live ecosystem data. Raven combines Stellar Docs search, LumenLoop ecosystem data, Stellar Light, and ecosystem skills into cross-referenced answers through two tools: `search` (find docs and ecosystem info) and `execute` (query live ecosystem data). It replaces Stella, the retired Stellar AI chat assistant.

The eight sub-skills are each self-contained; the larger ones are a short `SKILL.md` router plus companion files that load only when the task calls for them, so your agent pulls in the frontend or ZK material without dragging in the rest.
