Scalar Agent SDK

Connect your AI agent to Scalar's OpenAPI MCP servers. Provides native integrations for the Vercel AI SDK, OpenAI Agents SDK, and Anthropic Claude Agent SDK.

Installation

npm i @scalar/agent

pnpm i @scalar/agent

bun i @scalar/agent

Setup

import { agentScalar } from '@scalar/agent'

const scalar = agentScalar({
  token: 'your-personal-token',
})

const installation = await scalar.installation('your-installation-id')

Providers

Vercel AI SDK

Uses @ai-sdk/mcp natively. Returns a tool set ready for generateText / streamText.

import { agentScalar } from '@scalar/agent'
import { generateText, stepCountIs } from 'ai'

const scalar = agentScalar({
  token: 'your-personal-token',
})

const installation = await scalar.installation('your-installation-id')

const tools = await installation.createVercelAITools()

const { text } = await generateText({
  model,
  tools,
  stopWhen: stepCountIs(5),
  prompt: 'How do I create a planet?',
})

OpenAI Agents SDK

Returns options for MCPServerStreamableHttp from @openai/agents. The agent runtime handles tool discovery and execution natively.

import { agentScalar } from '@scalar/agent'
import { Agent, MCPServerStreamableHttp, run } from '@openai/agents'

const scalar = agentScalar({
  token: 'your-token',
})

const installation = await scalar.installation('your-installation-id')

const server = new MCPServerStreamableHttp(installation.createOpenAIMCP())
await server.connect()

const agent = new Agent({
  name: 'api-agent',
  mcpServers: [server],
})

const result = await run(
  agent,
  'Which APIs are available that let me create a planet?',
)

await server.close()

Anthropic Claude Agent SDK

Returns an MCP server configuration for @anthropic-ai/claude-agent-sdk.

import { agentScalar } from '@scalar/agent'
import { query } from '@anthropic-ai/claude-agent-sdk'

const scalar = agentScalar({
  token: 'your-token',
})

const installation = await scalar.installation('your-installation-id')

for await (const message of query({
  prompt: 'Which APIs are available that let me create a planet?',
  options: {
    mcpServers: {
      scalar: installation.createAnthropicMCP(),
    },
    allowedTools: ['mcp__scalar__*'],
  },
})) {
  if ('result' in message) console.log(message.result)
}

Configuration

| Option | Type | Description | | --------- | -------- | --------------------------------------------------------------------- | | token | string | Your Scalar Personal Token used to authenticate requests to your MCP | | baseUrl | string | Base URL of the Scalar MCP server.
