Plexum ProviderPlugin that serves MiniMax models through MiniMax's Anthropic-compatible HTTP endpoint (https://api.minimax.io/anthropic, or CN api.minimaxi.com). Inspired by openclaw's extensions/minimax provider-registration, but rewritten in Go for Plexum's SDK. internal/anthropic/ (~210 LOC + 6 tests): - minimal HTTP+SSE Anthropic Messages client (POST /v1/messages, stream:true, parses event:/data: SSE frames) - handles non-2xx as HTTP error; stream errors land as Event{Type:"error"} - 1 MiB SSE line cap; per-conn 5min timeout internal/translate/ (~220 LOC): - CanonicalToAnthropic: canonical.TurnRequest → MessagesRequest - blockToAnthropic: TextBlock / ToolUseBlock / ToolResultBlock / ThinkingBlock → loose ContentBlock map; preserves signatures + cache control - Translator: per-turn state machine; consumes anthropic.Event stream and emits canonical.TurnEvent stream (handles thinking blocks + tool_use input_json_delta accumulation + signature_delta capture) cmd/plexum-minimax-provider-plugin/: - Plugin manifest declares provider.models = [MiniMax-M2.7, MiniMax-M2.7-highspeed] - Backend fixed to "api" (per scope); region "global"|"cn" + base_url override supported via config - HostConfig from <profile>/plugins/plexum-minimax-provider/config.json {api_key, region?, base_url?, max_tokens_default?} scripts/install.sh: build + manifest emit; operator writes config.json + allows plugin + adds an agent + restarts. End-to-end verified against the real key: 1. plexum say --agent-id mini ... → "Hi, I'm MiniMax!" 2. Multi-turn continuity: agent recalled the prior reply 3. Via gateway socket: {"outcome":"text","text":"\n\npong"} 4. Via Fabric channel (alice posts → plugin inbound → mini agent → MiniMax → outbound REST → reply visible in bt2-clean seq=11): "Hi there! 👋 Fun fact: Octopuses have three hearts, blue blood, and neurons distributed throughout their arms—so their tentacles can 'think'" The MiniMax-M2.7-highspeed variant works the same way but hit a Code Plan rate-limit ceiling during testing (not a plugin issue). Deferred: - OAuth (Code Plan portal) — not in v1 scope per request - MiniMax Portal provider (separate provider id minimax-portal) - Image / TTS / video / music providers (separate plugins later) Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

# Plexum-minimax-provider
|
||
|
||
Plexum ProviderPlugin that serves **MiniMax** models via MiniMax's
|
||
Anthropic-compatible HTTP endpoint.
|
||
|
||
## Status
|
||
|
||
**v0.1 — current**: API key auth, streaming SSE, declared models
|
||
`MiniMax-M2.7` + `MiniMax-M2.7-highspeed`. Backend fixed to `api`
|
||
(global `https://api.minimax.io/anthropic` or CN `https://api.minimaxi.com/anthropic`).
|
||
|
||
**Deferred**: OAuth (Code Plan portal), MiniMax Portal provider, image /
|
||
TTS / video / music providers (separate plugins later if wanted).
|
||
|
||
## Install
|
||
|
||
```bash
|
||
cd ~/Plexum-minimax-provider
|
||
./scripts/install.sh
|
||
```
|
||
|
||
Then:
|
||
|
||
1. **Write API key** to `~/.plexum/plugins/plexum-minimax-provider/config.json`:
|
||
```json
|
||
{
|
||
"api_key": "sk-cp-..."
|
||
}
|
||
```
|
||
(`chmod 600` it.)
|
||
|
||
2. **Allow the plugin** in `~/.plexum/plexum.json`:
|
||
```json
|
||
{"plugins": {"allow": ["plexum-minimax-provider"]}}
|
||
```
|
||
|
||
3. **Point an agent at a MiniMax model**:
|
||
```bash
|
||
plexum agent-add --model MiniMax-M2.7 my-agent
|
||
```
|
||
|
||
4. **Restart** the gateway and talk:
|
||
```bash
|
||
systemctl --user restart plexum
|
||
plexum say --agent-id my-agent --session-id $(plexum new-session --agent-id my-agent) "hello"
|
||
```
|
||
|
||
## Config options
|
||
|
||
| Field | Default | Notes |
|
||
|---|---|---|
|
||
| `api_key` | (required) | `sk-cp-...` style key from MiniMax |
|
||
| `region` | `global` | `cn` switches to `api.minimaxi.com` |
|
||
| `base_url` | – | override either region's default |
|
||
| `max_tokens_default` | `4096` | used when `TurnRequest.MaxTokens` is unset |
|
||
|
||
## Architecture
|
||
|
||
- `internal/anthropic/` — minimal HTTP+SSE Anthropic Messages client
|
||
- `internal/translate/` — `canonical.TurnRequest` ↔ Anthropic Messages,
|
||
SSE Event → `canonical.TurnEvent` per-block state machine
|
||
- `cmd/plexum-minimax-provider-plugin/` — Plexum SDK ProviderPlugin entry
|
||
|
||
Both `text`, `thinking`, and `tool_use` content blocks round-trip
|
||
losslessly (signatures preserved for thinking blocks).
