OpenCode + Creddy

Configure OpenCode to use Creddy for secure credential management.

Overview

OpenCode is an open source AI coding assistant that runs in your terminal. Integrate it with Creddy to give it secure, scoped access to your development resources.

Prerequisites

OpenCode installed (go install github.com/opencode-ai/opencode@latest)
Creddy server running
Agent enrolled in Creddy

Configuration

OpenCode supports configuration via environment variables or a config file.

Environment Variables


# Shell function that injects credentials
opencode() {
  export ANTHROPIC_API_KEY=$(creddy get anthropic --format token)
  export OPENAI_API_KEY=$(creddy get openai --format token)
  export GITHUB_TOKEN=$(creddy get github --format token)
  command opencode "$@"
}

Config File

Alternatively, configure OpenCode to use a credential helper:


# ~/.opencode/config.yaml
credentials:
  anthropic:
    command: creddy get anthropic --format token
  openai:
    command: creddy get openai --format token
  github:
    command: creddy get github --format token

Multiple Model Support

OpenCode supports multiple LLM providers. With Creddy, you can give it access to any combination:


# Enroll the agent with multiple scopes
creddy agent create opencode \
  --scope "anthropic" \
  --scope "openai" \
  --scope "github:repo:myorg/*"

Usage

Run OpenCode normally — credentials are fetched on demand:


# Start an interactive session
opencode
 
# Or run a specific task
opencode "Add tests for the user service"

Self-Hosted Models

If you’re using self-hosted models (Ollama, vLLM, etc.), you may not need Creddy for the LLM. But you can still use it for GitHub and other services:


opencode() {
  # Only inject GitHub credentials, use local model
  export GITHUB_TOKEN=$(creddy get github --format token)
  export OPENCODE_MODEL="ollama/codellama"
  command opencode "$@"
}

Security Benefits

Credential isolation — each tool gets its own credentials
Short-lived tokens — API keys and tokens expire automatically
Audit logging — track which credentials OpenCode requested
Easy rotation — rotate backend credentials without updating OpenCode
