MCP · Streamable HTTPJSON APIschemaVersion 2026-10-24.2

Setup

Connect in one line

MCP endpoint: https://i-acc.si/api/mcp

Add the server from your terminal:

claude mcp add --transport http iaccum https://i-acc.si/api/mcp

Or commit it to the project as .mcp.json:

{
  "mcpServers": {
    "iaccum": {
      "type": "http",
      "url": "https://i-acc.si/api/mcp"
    }
  }
}

Add to your Codex config. Uses the mcp-remote bridge for HTTP servers:

# ~/.codex/config.toml
[mcp_servers.iaccum]
command = "npx"
args = ["-y", "mcp-remote", "https://i-acc.si/api/mcp"]

Generic MCP client config:

{
  "mcpServers": {
    "iaccum": {
      "type": "http",
      "url": "https://i-acc.si/api/mcp"
    }
  }
}

Or call it directly:

curl -s https://i-acc.si/api/mcp \
  -H 'content-type: application/json' \
  -H 'accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"iaccum_get_latest","arguments":{"limit":5}}}'
