Overview

AI-generated overview

Read-only Base chain token facts, ERC-20 allowance checks and Uniswap V3 LP accounting, with some tools paid per call in USDC.

What you can do
Exposes tools that read Base chain data at a pinned block: ERC-20 metadata, exact supply, bytecode hash and EIP-1967 implementation slot, plus ERC-20 allowance lookups that return exact units, decimals and provenance. A Uniswap V3 tool reconciles NFT and pool state, token inventory and fee-growth checkpoints against reported amounts and returns signed discrepancies. Free tools list mounted tool versions, prices and input schemas, show a fixed USDC sample, and report setup status. Paid tools cost 0.01 native USDC on Base per call.
When to use it
Useful when an assistant needs verifiable on-chain facts about Base tokens or allowances before proposing a spend, or when reconciling Uniswap V3 LP positions. Worth adding if you already hold USDC on Base and want read-only chain checks rather than transaction signing.
Requirements
A remote streamable HTTP endpoint; no local runtime or declared authentication. Paid tools require 0.01 native USDC on Base per call, settled through an x402 wallet, and are subject to shared paid pilot limits. Network access to the endpoint and to Base chain data.
Before you install
Several tools cost real money: 0.01 native USDC per call on Base, paid from an x402 wallet, with shared pilot limits. The tools only read chain state and do not approve or transfer tokens, but you are paying for each query. Outputs are on-chain facts, not financial advice.

Installation

In SourceWeft

  1. Open Paid Base Token Tools in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/app.replit.paid-mcp-opportunity-lab--taylorboucher1%2Fbase-token-tools/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
