Reworks @mem0/opencode-plugin to expose memory operations as native OpenCode tools (via the @opencode-ai/plugin `tool()` helper, backed by the mem0ai SDK) instead of delegating to the remote MCP server. Skills load via the `config` hook (`skills.paths`) instead of being copied into the project `.opencode/`. - Drop MCP: remove the regex-based MCP tool interception, the bundled opencode.json MCP registration, and the cli.ts installer (mem0-opencode bin). - Native tools: add_memory, search_memories, get_memories, get_memory, update_memory, delete_memory, delete_all_memories, delete_entities, list_entities, get_event_status. - Trim skills 16 -> 8 (context-loader, dream, forget, health, peek, pin, remember, tour); remove import, export, memory-reviewer, mem0, list-projects, switch-project, stats, onboard. De-MCP/onboard wording in kept skills. - Telemetry: emit the full shared plugin.* schema (adds user_prompt, bash_error, pre_compact, session_stop alongside session_start, tool_use); tool_use now fires from inside each native tool; add project_hash + os_version props. - Fix duplicate error-search (single topK:6); correct the documented experimental.chat.messages.transform hook name. - Bump to 0.2.0.

# @mem0/opencode-plugin
|
|
|
|
Persistent memory for [OpenCode](https://opencode.ai). Your agent remembers decisions, preferences, and learnings across sessions automatically.
|
|
|
|
## Install
|
|
|
|
```bash
|
|
opencode plugin @mem0/opencode-plugin
|
|
```
|
|
|
|
This adds the plugin to your `~/.config/opencode/opencode.json`. The plugin registers its memory tools and skills itself — there is no MCP server to configure.
|
|
|
|
**Or let your agent do it** — paste this into OpenCode:
|
|
|
|
```
|
|
Install @mem0/opencode-plugin by following https://raw.githubusercontent.com/mem0ai/mem0/main/integrations/mem0-plugin/.opencode-plugin/README.md
|
|
```
|
|
|
|
Get your API key (free): [app.mem0.ai/dashboard/api-keys](https://app.mem0.ai/dashboard/api-keys)
|
|
|
|
```bash
|
|
echo 'export MEM0_API_KEY="m0-your-key"' >> ~/.zshrc && source ~/.zshrc
|
|
```
|
|
|
|
Restart OpenCode.

## What's included
|
|
|
|
| Component | Description |
|
|
|-----------|-------------|
|
|
| **9 Native Memory Tools** | `add_memory`, `search_memories`, `get_memories`, `update_memory`, `delete_memory`, and more — registered as OpenCode tools, backed by the `mem0ai` SDK (no MCP server required) |
|
|
| **Lifecycle Hooks** | Auto-search on session start and every prompt, error memory lookup, compaction context, secret redaction |
|
|
| **8 Skills** | `/mem0:remember`, `/mem0:tour`, `/mem0:peek`, `/mem0:health`, `/mem0:dream`, `/mem0:forget`, `/mem0:pin`, `/mem0:context-loader` |
|
|
|
|
## Hooks
|
|
|
|
Pure TypeScript — no Python, no shell scripts. Memory operations are native OpenCode tools backed by the [mem0ai](https://www.npmjs.com/package/mem0ai) SDK directly.
|
|
|
|
| Hook | Event | What it does |
|
|
|------|-------|-------------|
|
|
| **Config** | `config` | Registers the bundled skills (`skills.paths`) and `/mem0:*` slash commands at startup |
|
|
| **Chat message** | `chat.message` | Loads prior memories on session start, searches relevant memories before each prompt, auto-captures learnings periodically |
|
|
| **Pre-tool** | `tool.execute.before` | Blocks MEMORY.md writes, steering them to the `add_memory` tool |
|
|
| **Post-tool** | `tool.execute.after` | Scans bash errors and pre-fetches related memories |
|
|
| **Messages transform** | `experimental.chat.messages.transform` | Injects memory context (session memories, search results, error lookups) into the prompt |
|
|
| **Compaction** | `experimental.session.compacting` | Stores session state memory, then injects prior memories into compaction context so nothing is lost |
|
|
| **Shell env** | `shell.env` | Exports `MEM0_USER_ID`, `MEM0_APP_ID`, `MEM0_SESSION_ID`, and `MEM0_BRANCH` to shell |
|
|
|
|
## Memory Tools
|
|
|
|
| Tool | Description |
|
|
|------|-------------|
|
|
| `add_memory` | Save text or conversation history |
|
|
| `search_memories` | Semantic search across memories |
|
|
| `get_memories` | List memories with filters and pagination |
|
|
| `get_memory` | Retrieve a specific memory by ID |
|
|
| `update_memory` | Overwrite a memory's text by ID |
|
|
| `delete_memory` | Delete a single memory by ID |
|
|
| `delete_all_memories` | Bulk delete all memories in scope |
|
|
| `delete_entities` | Delete an entity and its memories |
|
|
| `list_entities` | List users/agents/apps stored in Mem0 |
|
|
|
|
## Verify
|
|
|
|
Start OpenCode and ask: *"Search my memories for recent decisions"*
|
|
|
|
If the `mem0` tools respond, you're all set.
|
|
|
|
## Troubleshooting
|
|
|
|
| Problem | Fix |
|
|
|---------|-----|
|
|
| No tools appearing | Restart OpenCode after installing |
|
|
| 401 Unauthorized | `echo $MEM0_API_KEY` must print your `m0-` key |
|
|
| Plugin not loading | Run `opencode plugin @mem0/opencode-plugin` again |
