astra
Provides tools for interacting with Stellar networks, including validating StrKey addresses, probing live network/ledger status, and recording deployments on Stellar mainnet and testnet.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@astrarun a doctor check on my Web3 toolchains for Stellar and Base"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
astra — herramientas del protocolo ASTRA
astra es el CLI y el servidor MCP del protocolo ASTRA, un protocolo de desarrollo Web3 asistido por agentes de IA: multi-cadena (Stellar, Syscoin, Base y cualquier EVM), multi-vendor (funciona con cualquier runtime de IA) e independiente.
Cero dependencias. Node ≥ 20 y nada mas. Sin
npm install, sin build.Windows, macOS y Linux. CI en los tres sistemas operativos con Node 20 y 22.
Local-first. No envia telemetria ni llama a ninguna API de IA. Solo toca la red cuando se le pide sondear una cadena o clonar el protocolo.
Nunca firma ni custodia claves. Si le pasas una clave secreta, te lo dice y no la imprime (axioma A2 del protocolo).
Instalacion
git clone https://github.com/orlando-vazquez-career/astra-cli.git
cd astra-cli
node bin/astra.mjs --version # astra 0.1.0
npm link # opcional: deja `astra` en el PATH (no instala dependencias)Para que astra init y astra skills sync encuentren las plantillas y skills del protocolo:
astra protocol fetch # clona astra-protocol en ~/.astra/protocol (requiere git)
astra protocol path # muestra de donde lo esta leyendoTambien se resuelve desde ASTRA_PROTOCOL_DIR, desde ../../protocols/ASTRA relativo al CLI o con --protocol-dir <ruta>.

Comandos
Comando | Que hace | Red |
| Detecta toolchains (stellar, cargo, forge, cast, anvil, syscoin-cli, docker, hardhat local, target wasm32) y da un veredicto SAFE / CAUTION / AVOID por familia de cadena. | no |
| Registro de cadenas verificado: id, familia, red, chainId, CAIP-2, RPC, explorers, faucets, docs, notas. | no |
| Sonda en vivo: valida que el chainId (EVM) o la passphrase (Stellar) coincidan con el registro; reporta bloque/ledger y latencia. | si |
| Valida formato y checksum: StrKey (SEP-0023), EIP-55 (keccak-256 propio), bech32/bech32m y base58check (Syscoin UTXO). Detecta claves secretas y se niega a imprimirlas. | no |

Cualquier otra EVM se sondea con astra chain probe <id-parecido> --rpc <url> o se agrega al registro: una entrada en data/chains.json con verifiedAt (fecha en que se probaron sus URLs en vivo) y una guia en el protocolo. Todos los endpoints del registro se verificaron en vivo el 2026-09-04; el RPC de Rollux testnet no respondio ese dia y su entrada lo dice.
Registrar el servidor MCP
El servidor expone astra_doctor, astra_chain_list, astra_chain_info, astra_chain_probe, astra_address_validate, astra_check, astra_deployments_list, astra_deployments_add y astra_standards_search.

# Codex CLI
codex mcp add astra -- node /ruta/a/astra-cli/bin/astra.mjs mcpCursor (.cursor/mcp.json), Kimi Code (~/.kimi-code/mcp.json), Gemini CLI / Antigravity y OpenCode usan la misma forma JSON:
{ "mcpServers": { "astra": { "command": "node", "args": ["/ruta/a/astra-cli/bin/astra.mjs", "mcp"] } } }En Windows la ruta se escribe con barras normales o con \\\\.
Politica de claves
El CLI no firma, no despliega y no guarda claves. Los despliegues los hace el humano (o un agente con alias de un keystore nativo: stellar keys, cast wallet) y astra deployments add los registra despues. astra check falla si encuentra una semilla StrKey, una clave privada EVM junto a PRIVATE_KEY/secret/mnemonic, un mnemonico o un .env versionado; el hallazgo dice archivo y linea, nunca el valor.
