Overview

AI-generated overview

A local stdio MCP server that gives an assistant Clervo search and AI tools plus bounded, opt-in paid operations through a local wallet.

What you can do
Search and AI tools loaded from a selected profile (research, ai, prediction, crypto, sandbox or full). Execute profile-served operations through a single tool, with quotes bounded by per-operation and daily ceilings. Inspect shared local state: connection status, spend limits, local usage, reconciliation and diagnostics. Reconcile unresolved operations and replay with the same key without new payment authorization.
When to use it
When you want an assistant to use Clervo's search and AI tools, and possibly paid operations, from a local setup where spending limits and receipts matter. The profile flag lets you load only the schemas relevant to a given kind of agent.
Requirements
Node.js with npx to run the npm package @clervo/mcp as a local stdio process. Network access to the default origin or another HTTPS deployment or loopback set via CLERVO_BASE_URL. A local Clervo wallet for paid operations. No authentication is declared in the manifest.
Before you install
Paid operations can spend money: automatic payment is off by default and requires the explicit --auto-pay opt-in, after which quotes are still capped by per-operation and daily ceilings before signing. The server holds a local wallet, though status tools are said to expose state without wallet secrets. Unknown settlement blocks the server and other Connect surfaces. Hosted service use is subject to separate service terms.

Installation

In SourceWeft

  1. Open Clervo Connect in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

@clervo/mcp

Stdio MCP server for Clervo Connect. A clean one-command install uses the public production origin and the same local wallet, limits, receipts and unresolved operation state as every other Connect surface:

json
{  "mcpServers": {    "clervo": { "command": "npx", "args": ["-y", "@clervo/mcp"] }  }}

Claude Code:

sh
claude mcp add clervo -s user -- npx -y @clervo/mcp

The default origin is https://api.clervo.dev. Set CLERVO_BASE_URL only for another HTTPS deployment or loopback development.

Use --profile research|ai|prediction|crypto|sandbox|full to load only the schemas relevant to an agent. Profiles are checked against the live registry on every execution. RPC is not exposed while runtime truth reports it unavailable.

Alongside useful Search and AI tools, clervo_execute safely exposes operations served in the selected profile. connect_status, spend_limits, local_usage, reconcile, and doctor expose shared local state without wallet secrets.

Automatic payment is off by default. --auto-pay is an explicit local opt-in; even then, every quote is bounded by the Router's per-operation and daily ceilings before signing. Unknown settlement blocks MCP and every other Connect surface. Reconciliation and same-key replay carry no fresh payment authorization, and the server never blindly retries.

The package writes MCP protocol messages to stdout and operational failures to stderr only. This client code is MIT licensed; use of the hosted Clervo service remains subject to its service terms.
