# Connect MCP Servers to Atlas (2026)

> Atlas supports local stdio and remote HTTP MCP servers, including tools, prompts, resources, timeouts, and remote OAuth flows.

Atlas is an MCP client in 2026. It connects to local stdio servers and remote HTTP servers, discovers tools, prompts, and resources, and exposes them through the Atlas terminal workflow. Remote servers can use OAuth when supported. Each server remains a separate trust and data boundary that the organization must review.

## Key takeaways

- Atlas supports local stdio and remote HTTP MCP connection classes.
- MCP tools, prompts, and resources are discovered from each configured server.
- Remote OAuth, request timeouts, and server lifecycle handling are implemented.
- MCP compatibility is protocol support, not a certification or blanket approval of every server.

## Supported MCP surfaces

Atlas handles 3 core server surfaces: tools for actions, prompts for reusable instructions, and resources for retrievable context.

Local servers launch through stdio. Remote servers connect through HTTP transport, with OAuth discovery and callback handling when configured. Atlas also tracks connection status, request timeouts, and server changes.

## Trust boundary

Every 1 MCP server can read or change only what its process, credentials, and exposed tools allow, so scope each integration deliberately.

Use least-privilege credentials, review the server's code and operator, and keep high-risk actions behind Atlas permission prompts. A remote MCP server can create an external data route even when the selected model is local.

## Compatibility status

The 2026 registry labels MCP as protocol supported because Atlas implements the client boundary, not because every extension or third-party server has been certified.

Atlas does not claim inclusion in an official MCP client matrix until an external listing is visible. Test each required server and protocol feature against the Atlas version approved for the organization.

## Setup

1. Identify a trusted MCP server and document the data and actions it can access.
2. Run atlas mcp add and choose a local command or remote URL.
3. Inspect the saved connection with atlas mcp list.
4. For a remote server that requires OAuth, run atlas mcp auth <name>.
5. Use atlas mcp debug <name> and a low-risk test before enabling production credentials.

## FAQ

### Is Atlas an MCP client?

Yes. Atlas connects to configured MCP servers and exposes discovered tools, prompts, and resources in its terminal workflow.

### Does Atlas support remote MCP servers?

Yes. Atlas implements remote HTTP transport and OAuth flows, alongside local stdio server processes.

### Does MCP support make every server safe to use?

No. Each server has its own operator, code, credentials, tools, and data routes. Review and scope each one before use.

### Has the MCP project issued Atlas vendor recognition?

Atlas makes no certification claim. The public status means Atlas implements and tests the protocol client boundary; external listings are tracked separately.
