The Lucid base runtime (@lucid-fdn/agent-runtime) is a pre-built Docker image configured entirely through environment variables. It runs a minimal Express server on port 3100 that handles inference and automatic receipt creation.

​
Core Environment Variables

These are injected automatically when you launch through Lucid:
VariableRequiredDescription
LUCID_API_URLYesLucid Layer API base URL
LUCID_PASSPORT_IDYesAgent’s passport identity
LUCID_API_KEYYesAuthentication key for the Lucid API
LUCID_WALLET_ADDRESSAutoAgent wallet address (auto-created on launch)

​
Inference Configuration

VariableDefaultDescription
PROVIDER_URL—OpenAI-compatible inference endpoint (TrustGate, Ollama, vLLM, LiteLLM)
PROVIDER_API_KEY—API key for the inference provider
LUCID_MODEL—Model to use (e.g., openai/gpt-4o)
LUCID_PROMPT—System prompt for the agent
LUCID_TOOLS—Comma-separated list of enabled tools
TRUSTGATE_URL—TrustGate URL (if using Lucid-managed inference)

​
Memory Configuration

MEMORY_ENABLEDfalseEnable agent memory
MEMORY_STOREsqliteStorage backend: sqlite, postgres, or memory
MEMORY_DB_PATH./data/agents/{passport}/memory.dbSQLite database path
MEMORY_EXTRACTION_ENABLEDfalseEnable LLM-based memory extraction
MEMORY_EMBEDDING_ENABLEDfalseEnable vector embeddings for semantic search
MEMORY_EMBEDDING_PROVIDERnoneEmbedding provider: openai, mock, or none
