VS Code Iris list_discovery_sources
How to: VS Code Iris list_discovery_sources
Add Iris to VS Code
-
01
Open .vscode/mcp.json and merge this in. Keep any servers already there.
{
"servers": {
"iris": {
"type": "http",
"url": "https://api.iris-ai.dev/mcp"
}
}
}-
02
Save the file and restart VS Code.
-
03
Ask for something list_discovery_sources does. VS Code lists the server's tools on connect and calls list_discovery_sources itself — you do not invoke it by name.
-
04
If nothing happens, check the server is running and that Iris's identifier in your config matches the one above exactly.
Requires agent mode. MCP: Open User Configuration puts the same block in every workspace. VS Code docs
Set these first
Iris will not start until these are set, so list_discovery_sources never becomes available.

Same tool, other clients
This list was read from the server itself, by connecting to it and calling tools/list on 10 November 2026. It is what
the server actually exposes, not what its listing claims.
Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
