### Description (declared)

# OpenCode History MCP

A local MCP (Model Context Protocol) server that lets AI coding agents
search your **past OpenCode conversations** — before they start
exploring files or re-doing work you already did.

Everything runs on your machine: it reads OpenCode's own SQLite database
and builds a private full-text search index next to it. No network
calls, no external services, **no data ever leaves your computer**.

## Why

If you use [OpenCode](https://opencode.ai) daily across many projects,
you build up thousands of past sessions — bug fixes, feature work,
diagnostics — sitting untapped in `opencode.db`. When you start a new
session on the same module or file, your agent has no idea any of that
happened. It re-explores from scratch, or worse, repeats a mistake you
already fixed three weeks ago.

This server exposes that history as MCP tools any agent can call:
*"has this file been touched before? what did we conclude last time?
what related work exists in this project?"*

## How it works

```
OpenCode's own DB (read-only)          Our derived index (read-write)
┌─────────────────────────┐            ┌──────────────────────────┐
│ opencode.db              │  builds →  │ opencode-history.db       │
│ - session / message /part│            │ - sessions (denormalized) │
│ - JSON blobs per row      │            │ - search_idx (FTS5)       │
└─────────────────────────┘            │ - session_files (index)   │
                                        └──────────────────────────┘
```

- **Source DB stays untouched.** We open it `mode=ro` (read-only, WAL-aware)
  and never write to it.
- **A separate FTS5 index** holds denormalized session metadata + full-text
  search over user/assistant text — orders of magnitude faster t…
