## How it works (30 seconds)
```
You (chat) → MCP client → api-contract-mcp → API Contract APIs / CLIs / local tools
```
---
## Prerequisites
| Requirement | Notes |
|-------------|--------|
| **Node.js 18+** | ESM TypeScript MCP server |
| **Credentials / CLIs** | See environment variables below |
---
## Install
### Option A — npm (after publish)
```bash
npm install -g @mhdd_24/api-contract-mcp
```
### Option B — npx
```bash
npx @mhdd_24/api-contract-mcp
```
### Option C — clone and build
```bash
git clone https://github.com/Mhdd-24/API-Contract-MCP.git
cd API-Contract-MCP
npm install
npm run build
node dist/index.js
```

## Configure Cursor
Edit `~/.cursor/mcp.json`:
```json
{
"mcpServers": {
"apicontract": {
"command": "npx",
"args": ["-y", "@mhdd_24/api-contract-mcp"],
"env": {
"PROJECT_ROOT": "..."
}
}
}
}
```
**Local development:**
```json
{
"command": "node",
"args": ["/absolute/path/to/API-Contract-MCP/dist/index.js"]
}
```

Scored across 3 tools
Each tool has a distinct purpose: health check, response validation, and endpoint listing. There is no overlap or ambiguity between them.
All tools share a consistent 'apicontract_' prefix and use lowercase names. There is minor inconsistency between nouns ('status', 'endpoints') and verbs ('validate'), but the pattern is still predictable.
Three tools is on the smaller side but appropriate for a focused API contract utility. Each tool serves a clear, non-redundant function, and the count does not feel artificially inflated or overly thin.
The tool set covers core health check, validation, and endpoint discovery, but lacks broader contract lifecycle operations like importing, diffing, or managing multiple contracts. Agents can perform basic tasks but may need external tooling for full contract workflows.
