Januscope MCP Server
JanuScope is the local MCP policy proxy. One YAML wraps any MCP server with policy, redaction, audit, and database-schema injection. JanuScope runs locally, with no hosted gateway in the data path. Your upstream server and model provider can still receive data.
People who work with audit log, github and guardrails and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Januscope
before you install - you'll need
Set DATABASE_URI, MYSQL_HOST, MYSQL_PORT, MYSQL_USER, MYSQL_PASS, MYSQL_DB, MDB_MCP_CONNECTION_STRING, CLICKHOUSE_HOST, CLICKHOUSE_PORT, CLICKHOUSE_USER, CLICKHOUSE_PASSWORD before connecting. CLICKHOUSE_DATABASE is optional or environment-specific per the README.
Claude Code
claude mcp add giancarloerra-januscope -- npx -y januscope Claude Desktop / Cursor / VS Code - add to config
{
"mcpServers": {
"giancarloerra-januscope": {
"command": "npx",
"args": [
"-y",
"januscope"
]
}
}
} Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.
Using another client? Same JSON, different key

06 · Januscope FAQ
What is Januscope?
JanuScope is the local MCP policy proxy. One YAML wraps any MCP server with policy, redaction, audit, and database-schema injection. JanuScope runs locally, with no hosted gateway in the data path. Your upstream server and model provider can still receive data.
Is Januscope still maintained?
Yes - as of 2026-09-18, its last commit was 2026-09-18 and it shipped 1 release in the last 90 days. We re-verify nightly.
How do I install Januscope?
Run `npx -y januscope`. The README documents 12 environment variables (DATABASE_URI, MYSQL_HOST, MYSQL_PORT…) to set first. Set DATABASE_URI, MYSQL_HOST, MYSQL_PORT, MYSQL_USER, MYSQL_PASS, MYSQL_DB, MDB_MCP_CONNECTION_STRING, CLICKHOUSE_HOST, CLICKHOUSE_PORT, CLICKHOUSE_USER, CLICKHOUSE_PASSWORD before connecting. CLICKHOUSE_DATABASE is optional or environment-specific per the README. You can also paste the ready-made client config above.
Does Januscope run locally?
Yes - it's a stdio server: it runs on your machine (via npx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
