How to add JsonPlace MCP to Opencode

Install in Opencode by pointing it at https://jsonplace.com/mcp. Public mode works without any auth header, and you can add your JsonPlace API key later for saved templates and endpoint management.

Start in public mode

Opencode config
{
  "mcp": {
    "jsonplace": {
      "type": "remote",
      "url": "https://jsonplace.com/mcp",
      "enabled": true
    }
  }
}

Optional: add account features

Opencode config
{
  "mcp": {
    "jsonplace": {
      "type": "remote",
      "url": "https://jsonplace.com/mcp",
      "headers": {
        "Authorization": "Bearer jpak_your_real_key_here"
      },
      "enabled": true
    }
  }
}

When you need the API key

Public mode covers fake JSON, field discovery, one-off endpoint creation, and public response lookup. Add your API key only if you want saved templates and endpoint management.

Why this setup works

Use the no-auth snippet first, then add the Authorization header later if you want saved templates and endpoint management.

  • Remote MCP URL: https://jsonplace.com/mcp
  • Public mode works without an API key.
  • Add the Authorization bearer header only if you want saved templates and endpoint management.

Install steps

  1. Add the hosted JsonPlace MCP server

    Point your MCP client at https://jsonplace.com/mcp. Public mode works without any Authorization header.

  2. Paste the snippet into your client config

    Add JsonPlace as a remote MCP server with no headers for public mode.

  3. Restart the client

    Reload the MCP client so it reconnects with the new JsonPlace API key and makes the tools available.
