Tool — Remote MCP server, no auth (type: mcp)

Attach a public remote MCP server (no credentials) to a toolbox. A no-auth server still needs a connection (--kind remote-tool --auth-type none) — the toolbox references it by name and the created toolbox tool carries a populated project_connection_id.

🚦 Before creating a toolbox/connection either way, read create-hosted.md → Toolbox creation boundary.

A. Imperative CLI

Steps 1–3 of toolbox.md § The flow. Write the toolbox spec to a file — azd ai toolbox create --from-file takes a path (stdin - is not supported).

# 0. Install the CLI extension (once)
azd extension install azure.ai.toolboxes

# 1. Create the no-auth connection
azd ai connection create learn-mcp-conn \
  --kind remote-tool --target https://learn.microsoft.com/api/mcp \
  --auth-type none --project-endpoint "$FOUNDRY_PROJECT_ENDPOINT"

# Write the toolbox spec to a file
cat > learn-mcp.yaml <<'EOF'
description: learn-mcp toolbox
connections:
  - name: learn-mcp-conn
EOF

Create a new toolbox (first version auto-promoted):

azd ai toolbox create learn-tools --from-file learn-mcp.yaml --project-endpoint "$FOUNDRY_PROJECT_ENDPOINT"

azd ai toolbox create / delete require an azd environment (run inside an azd init'd directory), unlike connection create / toolbox show which work with just --project-endpoint.

Add to an existing toolbox (new version — then promote):

azd ai toolbox connection add learn-tools learn-mcp-conn --project-endpoint "$FOUNDRY_PROJECT_ENDPOINT"
