Do I need to install anything to use SWT3 AI Witness?

Yes. SWT3 AI Witness runs as a local process, so the package has to be installed on the machine where the client runs.

How do I install SWT3 AI Witness?

Install the npm package @tenova/swt3-mcp and run it with npx -y @tenova/swt3-mcp.

Does SWT3 AI Witness need an API key?

Yes. It reads 6 environment variables from the environment, so you need to supply SWT3_API_KEY, SWT3_TENANT_ID, SWT3_CONFIG_FILE, SWT3_CLEARING_LEVEL, SWT3_AGENT_ID, SWT3_SIGNING_KEY before the server will start.

What is SWT3_API_KEY used for in SWT3 AI Witness?

SWT3 API key (starts with axm_). Omit for zero-config demo mode.

Which transport does SWT3 AI Witness use?

Stdio. Your client has to support that transport to connect.

Where is the source code for SWT3 AI Witness?

The publisher lists https://github.com/tenova-labs/swt3-ai as the source repository.

Is SWT3 AI Witness an official server?

It is published under the namespace io.tenova, which means the publisher proved control of that domain when registering. That confirms who published it, not that it has been reviewed for quality or security.

Which version of SWT3 AI Witness is listed here?

Version 0.7.0, taken from the latest registry entry.

Tools

The publisher has not disclosed a tool manifest. The tool list can only be seen by connecting to the server, which this catalogue does not do on the publisher's behalf.

Command line alternative

None found. The published package declares no executable and no matching Homebrew formula exists, so the MCP server appears to be the only route. This is a negative result from automated checks, not a statement from the publisher.
