README

cognition-claude-proxy

A local proxy that lets **Claude Code** (or any Anthropic-API client) use **Devin's model catalog** — SWE-2, GLM-5.2, DeepSeek V4.1 Flash, and 200+ others — as its backend. It translates the Anthropic Messages API to the Connect-RPC format that the Devin CLI uses, and translates the streaming responses back to Anthropic SSE.

Plain-text flow

claude  (ANTHROPIC_BASE_URL=http://localhost:8765)
  -> POST /v1/messages            (Anthropic Messages API, JSON)
    -> proxy: translate to Connect-RPC protobuf
      -> POST https://server.codeium.com  (authenticated via local Devin CLI credentials)
    <- Connect server-stream of events (text/thinking/tool-call/usage)
  <- Anthropic SSE events (message_start/content_block_*/message_delta)

The proxy authenticates using your local Devin CLI credentials (`%APPDATA%\devin\credentials.toml` on Windows, `~/.config/devin/credentials.toml` on Linux/macOS). No API keys to manage — if `devin` works, `dclaude` works.

Prerequisites

Node.js 18+
Devin CLI installed and authenticated (devin command works)
Claude Code installed (claude command works)

Quick start

git clone https://github.com/coderexpert123/cognition-claude-proxy.git
cd cognition-claude-proxy

# Option A: use the wrapper (auto-starts the proxy)
bin\dclaude.bat -p "hello"

# Option B: start the proxy manually
node src/server.js            # starts on 127
