# mcp-config — shared MCP gateway config for laptops
|
|
|
|
Single source of truth for the **shared** MCP servers every covert-gpt user
|
|
gets through the LiteLLM gateway (`llm.covert-gpt.com`). Users install once;
|
|
their config then refreshes automatically on each new shell.
|
|
|
|
This repo lives in Gitea at `public/dotfiles`. (It is mirrored from the
|
|
`ai-k8s-iac` repo under `mcp-config/`; edit it there or here and keep them in
|
|
sync — the laptops pull from Gitea's `main`.)
|
|
|
|
## How it works
|
|
|
|
- `opencode.gateway.json` — the shared server list. **Identical for every
|
|
user**: the per-user key is injected via `{env:LITELLM_KEY}`, never written
|
|
into the file. Add a gateway server here and everyone picks it up next shell.
|
|
- `sync.sh` — sourced from each user's shell rc. On a new shell it pulls
|
|
`opencode.gateway.json` (throttled ~1h), drops it where opencode merges it,
|
|
and exports `LITELLM_KEY` from `~/.config/mcp-sync/key`. Silent + non-fatal:
|
|
a Gitea hiccup never breaks the shell, last-good config stays in place.
|
|
- `install.sh` — one-time bootstrap (curl-pipe). Fetches `sync.sh`, stores the
|
|
user's key (0600), and adds the rc hook.
|
|
|
|
opencode **merges** config files, so the synced `opencode.gateway.json`
|
|
coexists with each user's own `~/.config/opencode/opencode.json` and any
|
|
**local-only** MCP servers (e.g. a client-side `kubernetes` pointed at their
|
|
own kubeconfig). Sync never touches those.
|
|
|
|
## User setup (one time)
|
|
|
|
Each user needs a LiteLLM **virtual key** scoped to the gateway servers (see
|
|
`charts/inference/MCP-GATEWAY.md` in ai-k8s-iac for how keys are minted). Then:
|
|
|
|
```sh
|
|
curl -fsSL https://git.nic-oconnor.com/public/dotfiles/raw/branch/main/mcp-config/install.sh | sh
|
|
# (prompts for the sk-... key; or pass it: ... | LITELLM_KEY=sk-... sh)
|
|
```
|
|
|
|
Open a new terminal, run `opencode`, and the gateway tools are there.
|
|
|
|
## Adding a gateway server (admin)
|
|
|
|
1. Register it on the gateway (`charts/inference/values.yaml` →
|
|
`proxy_config.mcp_servers`), deploy, smoke-test.
|
|
2. Add a matching entry to `opencode.gateway.json` here and push to `main`.
|
|
3. Users get it automatically within the sync TTL (or immediately on a new
|
|
shell). No per-user action.
|
|
|
|
For **per-user / per-target** tools (cluster access, etc.) do NOT add them
|
|
here — those run client-side with the user's own credentials. See
|
|
`charts/inference/MCP-GATEWAY.md`.
|
|
|
|
## Notes / caveats
|
|
|
|
- **Local-server precedence**: opencode merges with later-config-wins on key
|
|
conflicts. If a user names a local server the same as a gateway one, theirs
|
|
wins. Use distinct names.
|
|
- **Key rotation**: re-run `install.sh` (or edit `~/.config/mcp-sync/key`).
|
|
- **Other clients**: this ships an opencode config. Claude Code / open-webui
|
|
would need their own equivalent file + a parallel sync entry; not done yet.
|
|
- **Throttle**: override with `MCP_SYNC_TTL=0` to force a pull every shell.
