For VS Code, you can add the configuration to your User Settings (JSON) or to a .vscode/mcp.json file in your workspace. Note that when using .vscode/mcp.json, the mcp key is not required.
Using NPX in VS Code:
{
"mcp": {
"inputs": [
{
"type": "promptString",
"id": "slack_bot_token",
"description": "Slack Bot Token (starts with xoxb-)",
"password": true
},
{
"type": "promptString",
"id": "slack_team_id",
"description": "Slack Team ID (starts with T)"
}
],
"servers": {
"slack": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-slack"],
"env": {
"SLACK_BOT_TOKEN": "${input:slack_bot_token}",
"SLACK_TEAM_ID": "${input:slack_team_id}"
}
}
}
}
}
Using Docker in VS Code:
{
"mcp": {
"inputs": [
{
"type": "promptString",
"id": "slack_bot_token",
"description": "Slack Bot Token (starts with xoxb-)",
"password": true
},
{
"type": "promptString",
"id": "slack_team_id",
"description": "Slack Team ID (starts with T)"
}
],
"servers": {
"slack": {
"command": "docker",
"args": ["run", "-i", "--rm", "mcp/slack"],
"env": {
"SLACK_BOT_TOKEN": "${input:slack_bot_token}",
"SLACK_TEAM_ID": "${input:slack_team_id}"
}
}
}
}
}
{
"mcp": {
"inputs": [
{
"type": "promptString",
"id": "slack_bot_token",
"description": "Slack Bot Token (starts with xoxb-)",
"password": true
},
{
"type": "promptString",
"id": "slack_team_id",
"description": "Slack Team ID (starts with T)"
}
],
"servers": {
"slack": {
