Connect an MCP server

A connector is an MCP server NeuralVault may run on an agent’s behalf. You test it first, then choose which of its tools an agent may call.

Steps

Open Settings, then AI & extensions, then Connectors and integrations.
Add a connector: give it a name, the command that starts the server, and its arguments.
If the server needs credentials, enter the environment variable NAMES here, not their values. Never type a secret into the command or arguments boxes: both are shown back to you in the connector list, and neither is treated as sensitive.
Press "Test connection". This runs the server once and asks it for its real tool list, so what you see next is what the server actually offers rather than something typed by hand.
Tick the tools you want to grant. Save is deliberately disabled until a test has succeeded, because there is nothing to save before then.
Save the connector.

How to tell it worked

The connector appears in the list with the tools you granted. Its tools become available to agents.

If it does not work

The test fails immediately.: The command is what a shell would run. Check the program is on your PATH, and that the arguments are separate entries rather than one string with spaces in it.
The test succeeds but the tools do not work later.: Almost always missing credential values. Declaring the variable name is only half of it. See "Give a connector its credentials".
You granted a tool but an agent still will not call it.: Granting and marking read-only are separate ticks. A granted tool that is not marked read-only waits for your approval before an agent may run it, which is the deliberate default.
