### Description (declared)

# mouser-search-mcp

Model Context Protocol server for the [Mouser Electronics Search API](https://api.mouser.com/api/docs/ui/index).

Exposes the Mouser Search API as MCP tools so MCP-aware clients (Claude Code, Claude Desktop, etc.) can query Mouser's parts catalog.

## Tools

| Tool | Endpoint | What it does |
| --- | --- | --- |
| `search_by_keyword` | `POST /api/v1/search/keyword` | Keyword search across the catalog (up to 50 parts). Supports paging and RoHS/in-stock filters. |
| `search_by_part_number` | `POST /api/v1/search/partnumber` | Look up 1–10 part numbers (pipe-separated), with optional exact-match. |
| `search_by_keyword_and_manufacturer` | `POST /api/v2/search/keywordandmanufacturer` | Keyword search scoped to one manufacturer by name. |
| `search_by_part_number_and_manufacturer` | `POST /api/v2/search/partnumberandmanufacturer` | Part-number lookup scoped to one manufacturer by name. |
| `list_manufacturers` | `GET /api/v2/search/manufacturerlist` | Enumerate manufacturer names (use the result to populate the `manufacturer_name` argument on the two manufacturer-filtered tools). |

## Prerequisites

- Python 3.10+
- A Mouser **Search API** key — request one at <https://www.mouser.com/api-search/>.

## Install

Using [`uv`](https://docs.astral.sh/uv/) (recommended):

```bash
uv pip install -e .
```

Or with pip:

```bash
pip install -e .
```

## Configure

The server reads the API key from the `MOUSER_API_KEY` environment variable. Copy `.env.example` to `.env` and fill in your key, or export it in your shell.

## Run

The server speaks MCP over stdio:

```bash
MOUSER_API_KEY=... mouser-search-mcp
```

## Use with Claude Code

Register the server (replace the path and key):

```bash
claude mcp add mouser-search \
  --env MOUSER_API_KEY=your-key \
  -- mouser-search-mcp
```

## Use with Claude Desktop

Add to `claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "mouser-search": {
      "command": "mouser-search-mcp",
      "env": {
        …
