@secr/mcp
Provides AI coding agents with direct access to secrets management (get, set, list, delete secrets, and list environments) through the Model Context Protocol, enabling secure secret operations during development.
README
@secr/mcp
Secr MCP server — gives AI coding agents (Claude Code, Cursor, Copilot) direct access to secrets via the Model Context Protocol.
Install
npm install @secr/mcp
Setup
Claude Code
claude mcp add secr -e SECR_TOKEN=secr_agent_xxx -- npx @secr/mcp
Cursor
Add to ~/.cursor/mcp.json:
{
"mcpServers": {
"secr": {
"command": "npx",
"args": ["@secr/mcp"],
"env": { "SECR_TOKEN": "secr_agent_xxx" }
}
}
}
VS Code (Copilot)
Add to .vscode/mcp.json:
{
"servers": {
"secr": {
"command": "npx",
"args": ["@secr/mcp"],
"env": { "SECR_TOKEN": "secr_agent_xxx" }
}
}
}
Tools
The server exposes 5 tools to AI agents:
| Tool | Description |
|---|---|
get_secret |
Get a single secret value by key |
list_secrets |
List secret key names (no values) with optional search |
set_secret |
Create or update a secret |
delete_secret |
Delete a secret |
list_environments |
List environments for a project |
All tools accept optional org, project, and environment parameters. When omitted, they resolve from environment variables or .secr.json.
Environment Variables
| Variable | Required | Default | Description |
|---|---|---|---|
SECR_TOKEN |
Yes | -- | Agent token (secr_agent_...) |
SECR_ORG |
No | .secr.json |
Organization slug |
SECR_PROJECT |
No | .secr.json |
Project slug |
SECR_ENVIRONMENT |
No | .secr.json |
Default environment slug |
SECR_API_URL |
No | https://api.secr.dev |
API base URL |
Creating an Agent Token
secr agents create --name "claude-code" --scope "read:secrets,write:secrets"
Agent tokens use scoped permissions — the server only has access to what the token allows.
