## Documentation

### Tides JSON-RPC Access

Use this guide to call the deployed API directly:

Base URL: https://hamandmore.net/api/harmonics/mcp
Method: POST
Content-Type: application/json
Protocol: JSON-RPC 2.0 request envelope

### Authentication

Use one of these modes:

Anonymous: no Authorization header (free tier rate limits)
Keyed: add Authorization: Bearer <token> or Authorization: Basic <token>
Need higher usage tiers? Request authentication by emailing hamandmore@gmail.com.

Important:

Basic here is an opaque token prefix, not RFC Basic base64 decoding.
Tokens do not need to be valid base64.

### JSON-RPC Envelope

Always send:

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/list",
  "params": {}
}

id: any client correlation value
method: one of initialize, tools/list, tools/call
params: object (required shape depends on method)

### Quick Start Commands

Initialize:

curl -sS -X POST https://hamandmore.net/api/harmonics/mcp \\
  -H 'content-type: application/json' \\
  --data '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{}}'

List tools:

curl -sS -X POST https://hamandmore.net/api/harmonics/mcp \\
  -H 'content-type: application/json' \\
  --data '{"jsonrpc":"2.0","id":2,"method":"tools/list","params":{}}'

List tools (keyed tier):

curl -sS -X POST https://hamandmore.net/api/harmonics/mcp \\
  -H 'content-type: application/json' \\
  -H 'authorization: Bearer YOUR_TOKEN' \\
  --data '{"jsonrpc":"2.0","id":3,"method":"tools/list","params":{}}'

### Tool Call Pattern

All tool calls use:

{
  "jsonrpc": "2.0",
  "id": 10,
  "method": "tools/call",
  "params": {
    "name": "TOOL_NAME",
    "arguments": {}
  }
}

### 1) Current time (tides_time)

curl -sS -X POST https://hamandmore.net/api/harmonics/mcp \\
  -H 'content-type: application/json' \\
  --data '{"jsonrpc":"2.0","id":10,"method":"tools/call","params":{"name":"tides_time","arguments":{}}}'

### 2) Single tide value (tides_single)

curl -sS -X POST https://hamandmore.net/api/harmonics/mcp \\
  -H 'content-type: application/json' \\
  --data '{"jsonrpc":"2.0","id":11,"method":"tools/call","params":{"name":"tides_single","arguments":{"latitude":40.7128,"longitude":-74.0060,"time":"2026-02-10T00:00:00Z"}}}'

### 3) Tide extrema (tides_extrema)

curl -sS -X POST https://hamandmore.net/api/harmonics/mcp \\
  -H 'content-type: application/json' \\
  --data '{"jsonrpc":"2.0","id":12,"method":"tools/call","params":{"name":"tides_extrema","arguments":{"latitude":40.7128,"longitude":-74.0060,"start_time":"2026-02-10T00:00:00Z","end_time":"2026-02-11T00:00:00Z"}}}'

### 4) Weather points (weather_met)

curl -sS -X POST https://hamandmore.net/api/harmonics/mcp \\
  -H 'content-type: application/json' \\
  --data '{"jsonrpc":"2.0","id":13,"method":"tools/call","params":{"name":"weather_met","arguments":{"latitude":40.7128,"longitude":-74.0060,"start_time":"2026-02-10T00:00:00Z","variables":["wind/surface/0","tmp/surface/0"]}}}'

### Response Shape

Successful responses include:

result.content[0].text: stringified JSON result
result.structuredContent: same result as an object (preferred)

Errors use JSON-RPC error:

-32602: invalid params
-32601: method not found
-32603: server/tool exception
