Agent Engine

  • Agents know today's date. The current date and time are now part of every agent's system prompt, so date-based requests use the real date.
  • Steadier tool calls. Integration tools now send only the parameters an action needs instead of every input, so fewer actions fail on unexpected fields.
  • Fixes. Model errors now show up in the agent's response, webhook delivery is fixed, and agents with tasks accept a query given as a plain string.

SDK updates

  • MCP server connections. You can connect an MCP server as a tool and choose which of its actions an agent can use.
  • More ways to authenticate integrations. Integrations now accept API_KEY and BASIC authentication, next to bearer token, OAuth 1, OAuth 2 and no auth. The SDK looks up the methods each integration supports and tells you when a method or parameter is wrong.
  • Integration fixes. OAuth integrations connect correctly, and integration attributes are now passed through. You can also create integration tools with ToolFactory.
  • Create agents from a dictionary. create_from_dict() builds an agent or team agent from a dictionary and checks it first, so you can store a setup and load it again.
  • Recreate integration tools. recreate() rebuilds an existing integration tool with new parameters and keeps the same tool ID.
  • Clearer team agent errors. If a team agent's LLM ID doesn't exist, the error now names it and tells you which LLM parameters to set. Deployment errors for teams give more detail.

Marketplace

  • Onboard your MCP server. You can now add your own MCP server, and its tools become available to your agents.
  • Steadier integrations. Integrations moved to a newer connector version and list the actions each connector offers. Errors from an integration now reach you, and the callback after you connect an account works again.

Knowledge

  • Filter and prune index records. aiR indexes can now return the records that match a metadata filter and delete records by date.
  • Search finds more assets. Marketplace search now covers agents, tools and other asset types.

Accounts

  • Zero limits on API keys. API key budgets and per-day or per-minute request and token limits, for the whole key or a single asset, can now be set to 0. Before, every value had to be above 0.
