# @linusdevx/cpi-mcp-server

MCP server for SAP Cloud Platform Integration (CPI). Query packages, iFlows, message processing logs, partner directory entries, security material, and manage artifact lifecycle via the CPI OData API.

47 tools across 9 modules — all backed by the CPI OData v2 API.

## Install

Requires Node.js ≥20.

## Local development

```bash
git clone https://github.com/linusdevx/sap-cpi-mcp-server.git
cd sap-cpi-mcp-server
npm install
cp .env.example .env  # then fill in values
npm test
npm run dev           # runs src/index.ts via tsx, reads stdio
```

Available scripts:

- `npm run build` — compile to `dist/`
- `npm run dev` — run TS source via `tsx`
- `npm run typecheck` — `tsc --noEmit`
- `npm run format` / `npm run format:check` — Prettier
- `npm test` — run vitest once
- `npm run test:watch` — vitest in watch mode

## Manual smoke test

After `npm run build`, point a real tenant at the binary using the MCP Inspector or a direct stdio client:

```bash
MCP_CPI_BASE_URL=... MCP_CPI_TOKEN_URL=... \
MCP_CPI_CLIENT_ID=... MCP_CPI_CLIENT_SECRET=... \
node dist/index.js
```

Then send a `tools/list` request to verify all 47 tools register, followed by a low-impact read like `get_integration_packages`.

## Release flow

CI runs typecheck, format check, and tests on Node 20 and 22 against every PR. The publish workflow runs on `v*` tags and requires an `NPM_TOKEN` secret with publish rights to `@linusdevx/cpi-mcp-server`. See `CHANGELOG.md` for version history.

## Contributing

PRs welcome. Please run `npm run format && npm test` before opening a PR.
