Overview

AI-generated overview

SENTINEL is a local MCP server that acts as a pre-execution safety oracle for AI agents, screening Base contracts and simulating sells, paid per call via x402.

What you can do
  • Screen Base blockchain contracts before an agent acts on them
  • Simulate token sells to check outcomes before committing
  • Pay for oracle calls autonomously through x402 using a funded wallet
  • No individual tools are listed in the manifest, so exact operations are not documented.
When to use it
Worth considering when an AI agent is about to interact with contracts or tokens on the Base network and you want a safety check and sell simulation before execution.
Requirements
Runs as a local stdio process installed from the PyPI package sentinel-mcp, on desktop only. Requires the environment variable AGENT_WALLET_PRIVATE_KEY, a private key for a Base wallet holding USDC to pay for calls via x402. Network access to Base and the payment flow is implied.
Before you install
The server requires a wallet private key (AGENT_WALLET_PRIVATE_KEY) and spends USDC autonomously per call, so a dedicated, low-balance wallet is advisable. Contract screening and sell simulation are advisory and may not prevent losses. No tools, README or instructions are published, so behavior cannot be verified before installing.

Installation

In SourceWeft

  1. Open SENTINEL 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.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
