> ## Agent Instructions
> To act on Atlan objects, use the Atlan MCP server at https://api.atlan.com/mcp or the SDK. To install or publish skills from a terminal, use the `brain` CLI; `brain --map json` prints its command map. The `atlanai` CLI is deprecated. Run a read-only identity check before any write.
> The docs MCP server at /mcp searches these docs only. It cannot read or change Atlan objects.
> SDK packages: Python `atlanai` (PyPI) and TypeScript `@atlanai/sdk` (npm). Show Python first, then TypeScript.
> These docs cover Atlan Agent Registry, Atlan's hosted product. The open-source agent registry specification and its CLI (`brain`) are documented, released and maintained in their own repository; /open-source on this site links to it. Answer general specification or `brain` command questions from the project's own docs, and use these docs only for Atlan-specific setup such as the Atlan adapter, sign-in and workspaces.

# API · 8 October 2026 (0.9.70–0.9.127)

> Several creates now return a `Location` header, MCP sessions open with `mcp__initialise`, and an agent rename is no longer silently ignored.

Released 8 October 2026 · API 0.9.70–0.9.127.

## Improvements

* **Agents:** `POST /agent/v1/agents`, `POST
  /agent/v1/agents/\{agent_id\}/sessions` and the other Agents API creates now
  return a `Location` header with the new resource's address.
* **MCP:** `GET /mcp/v1/servers` no longer lists a system `registry` server: new
  accounts don't get one, and reconcile archives an existing one.
* **MCP:** `tools/list` now lists `mcp__initialise` to open a session, in place
  of `registry__initialise`, which still works when called by name.
* **Registry:** `POST /registry/v1/workspaces`, `POST
  /registry/v1/service-accounts` and `POST /registry/v1/repos` (for a new repo)
  now return a `Location` header with the new resource's address.
* **Skills:** `POST /skill/v1/skills` now returns a `Location` header with the
  new skill's address.

## Fixes

* **Agents:** Fixed `PATCH /agent/v1/agents/{agent_id}` reporting success
  without renaming when the body sets a new `name`; it now refuses with
  `immutable_field`.
* **Agents:** Fixed `POST /agent/v1/agents/{agent_id}/sessions` failing when the
  `prompt` spans several lines and no `title` is given.
* **MCP:** Fixed `POST /mcp/v1/servers/{server_id}/refresh` listing unchanged
  tools under `updated` when the server's tools were catalogued by an earlier
  release.
