## Description
Natural language API discovery — search 700+ API capabilities, get endpoints, auth setup, and code snippets. Supports auto-discovery of new APIs.

## Tools
Capabilities this server exposes over MCP:

- **semantic_query** — Search for an API capability using natural language.
- **semantic_discover** — Deep discovery of a specific provider/API by name and intent.
- **semantic_discover_url** — Analyze any API from its documentation URL.

## Claude Desktop Quick Installation
Install path detected from listing signals. Uses `uvx` (confidence: high):

```json
"mcpServers": {
  "semanticapi-mcp": {
    "command": "uvx",
    "args": ["semanticapi-mcp"],
    "env": {
      "SEMANTIC_API_KEY": "",
      "SEMANTIC_API_URL": ""
    }
  }
}
```

**Requires environment variables:** `SEMANTIC_API_KEY`, `SEMANTIC_API_URL` — the values above are empty placeholders; fill in real credentials before running (see the repository for what each one is for).

## Documentation & README

# Semantic API MCP Server

<!-- mcp-name: io.github.peter-j-thompson/semanticapi -->

An [MCP (Model Context Protocol)](https://modelcontextprotocol.io) server that lets Claude, ChatGPT, and other LLM agents search and discover APIs using natural language via [Semantic API](https://semanticapi.dev). Ask for any API capability in plain English and get back endpoint details, parameters, auth info, and code snippets.

## Install

```bash
pip install semanticapi-mcp
```

Or run directly with uvx:

```bash
uvx semanticapi-mcp
```

## Configuration

### Get an API Key

Sign up at [semanticapi.dev](https://semanticapi.dev) to get your API key.

### Environment Variables

| Variable | Required | Default | Description |
|----------|----------|---------|-------------|
| `SEMANTIC_API_KEY` | Yes | — | Your Semantic API key |
| `SEMANTIC_API_URL` | No | `https://semanticapi.dev` | API base URL override |

### Claude Desktop

Add to your Claude Desktop config (`~/Library/Application Support/Claude/claude_desktop_config.json`):

```json
{
  "mcpServers": {
    "semanticapi": {
      "command": "uvx",
      "args": ["semanticapi-mcp"],
      "env": {
        "SEMANTIC_API_KEY": "your-api-key-here"
      }
    }
  }
}
```

Or if installed with pip:

```json
{
  "mcpServers": {
    "semanticapi": {
      "command": "semanticapi-mcp",
      "env": {
        "SEMANTIC_API_KEY": "your-api-key-here"
      }
    }
  }
}
```

## Tools

### `semantic_query`

Search for an API capability using natural language.

**Inputs:**
- `query` (string, required) — What you want to do, e.g. "send an email with Gmail"
- `auto_discover` (boolean, optional, default: true) — Auto-discover new APIs if needed

**Example:** "Find me an API to convert currencies in real-time"

### `semantic_discover`

Deep discovery of a specific provider/API by name and intent.

**Inputs:**
- `provider_name` (string, required) — API provider name, e.g. "stripe", "twilio"
- `user_intent` (string, optional) — What you want to do with this API

**Example:** Discover Stripe's capabilities for "process a refund"

### `semantic_discover_url`

Analyze any API from its documentation URL.

**Inputs:**
- `url` (string, required) — URL of the API documentation
- `user_intent` (string, optional) — What you want to do with this API

**Example:** Analyze `https://docs.example.com/api` to generate a provider config
