MCP in Continue

Continue wires MCP through its experimental.modelContextProtocolServers array. Standard stdio transport, standard npx -y @ontosdk/mcp@latest command.

ℹ

Continue's MCP support is under experimental. The flag may move out of experimental in future releases — the inner schema (transport, command, args, env) stays the same.

Install steps

Get an API key

Grab a key from app.buildonto.dev/read/keys. Free tier: 1,000 requests / month.

Open Continue config

Continue reads from ~/.continue/config.json. Open it in your editor of choice — Continue auto-reloads on save.

Add the Onto MCP server

json~/.continue/config.json

{
  "experimental": {
    "modelContextProtocolServers": [
      {
        "transport": {
          "type": "stdio",
          "command": "npx",
          "args": ["-y", "@ontosdk/mcp@latest"],
          "env": { "ONTO_API_KEY": "onto_sk_live_your_key_here" }
        }
      }
    ]
  }
}

Save

Continue picks up config changes on save. Open a Continue chat to confirm the Onto tools appear.

Config file path

~/.continue/config.json on all platforms (macOS, Linux, Windows — Continue stores its config in the home directory regardless of OS).

Verify

In a Continue chat, ask: "What MCP tools do you have available?" read_url, score_url, and read_and_score should appear.

Try it: "Use Onto to read https://docs.continue.dev and tell me what it costs."
