Official Palveron MCP Server — Model Context Protocol integration for AI Governance

⚡ Early access. Palveron is launching soon and access is currently invite-gated. This server is fully functional — you just need a pv_live_ key, which comes with an Early Access invite. Join the waitlist → palveron.com/early-access

Run every tool call your MCP-capable client makes — Claude Code, Cursor, any other MCP host — through the Palveron AI Governance Gateway. Policies enforced, PII masked, decisions logged, audit trails anchored.

Drop-in MCP server — one binary, configure your MCP host, you're done
Real-time policy enforcement — block, modify, or allow each tool call before it executes
Audit trail per tool call — trace IDs flow back to the Palveron dashboard
Built on @palveron/sdk — retry, circuit breaker, typed errors out of the box

Installation

bash

npm install -g @palveron/mcp-server
# or use directly via npx
npx @palveron/mcp-server

Quick Start

The pv_live_… key in the examples below requires an Early Access invite — request one here. Once you have a key, everything works out of the box.

Claude Code

Add to your claude_desktop_config.json:

json

{
  "mcpServers": {
    "palveron": {
      "command": "npx",
      "args": ["@palveron/mcp-server"],
      "env": {
        "PALVERON_API_KEY": "pv_live_xxx",
        "PALVERON_BASE_URL": "https://gateway.palveron.com"
      }
    }
  }
}

Other MCP hosts

Any MCP-capable host can launch the server via the palveron-mcp binary:

bash

PALVERON_API_KEY=pv_live_xxx palveron-mcp

Tools exposed via MCP

Tool	Purpose
`palveron_verify`	Gate any prompt before the host sends it to the model. Returns `ALLOWED` / `BLOCKED` / `MODIFIED` plus the sanitized prompt.
`palveron_check_tool_call`	Gate a specific tool invocation against the agent's capability model.
`palveron_list_policies`	List the project's active guardrails so the host can explain its decisions.

Configuration

The server reads its configuration from environment variables. The MCP host sets them; you never put secrets in code.

Variable	Required	Description
`PALVERON_API_KEY`	yes	API key (`pv_live_…`) — comes with an Early Access invite
`PALVERON_BASE_URL`	no	Override the gateway endpoint (default: `https://gateway.palveron.com`)
`PALVERON_TIMEOUT_MS`	no	Request timeout in ms (default: 30000)

Requirements

Node.js 18 or newer
An MCP-capable client (Claude Code 0.4+, Cursor, etc.)
