Wallet Portfolio Tracker API
Let your coding agent fetch multi-chain wallet balances, ERC-20 holdings, and USD totals on Base and Ethereum without wiring block explorers yourself.
Overview
Wallet Portfolio Tracker is a Grow-phase MCP server that returns crypto wallet balances, ERC-20 token lists, and USD values across Base and Ethereum via an x402-enabled remote SSE endpoint.
What is this MCP server?
- Remote SSE MCP endpoint at wallet-portfolio.api.klymax402.com/mcp (server schema v2025-12-11)
- Wallet balances plus ERC-20 token positions with USD valuation across Base and Ethereum
- x402 micropayment-gated API so agents pay per call instead of you fronting a heavy indexer bill
- Packaged as Wallet Portfolio Tracker API v1.1.0 with GitHub source wallet-portfolio-x402
- Suited to agent workflows that need live on-chain portfolio snapshots for dashboards or alerts
- Server version 1.1.0 per MCP server.schema.json 2025-12-11
- Supports 2 EVM networks named in catalog copy: Base and Ethereum
- 1 remote SSE endpoint: https://wallet-portfolio.api.klymax402.com/mcp
What problem does it solve?
Agents cannot see your on-chain holdings unless you manually export balances or bolt together multiple chain explorers and price feeds.
Who is it for?
Indie builders adding wallet or treasury readouts to agents, internal ops bots, or lightweight crypto SaaS prototypes on Base and Ethereum.
Skip if: Teams that need historical tax lots, DeFi position decoding across dozens of chains, or fully free unlimited indexing without x402 per-call costs.
What do I get? / Deliverables
After you register the remote MCP URL, your agent can pull normalized portfolio snapshots on Base and Ethereum for dashboards, support scripts, or product copy without custom indexer code.
- Structured wallet balance and ERC-20 holdings with USD values
- Agent-ready portfolio answers across Base and Ethereum
- Repeatable MCP tool calls without custom indexer deployment
Recommended MCP Servers
Journey fit
Portfolio and balance visibility compounds after you ship—solo builders use it to monitor treasury, demos, and growth experiments rather than during first ideation. Analytics is the canonical shelf because the server answers what do I hold and what is it worth, not how to deploy contracts or scrape landing pages.
How it compares
On-chain portfolio MCP over SSE with x402 billing—not a Claude skill markdown pack or a local block explorer scraper.
Common Questions / FAQ
Who is Wallet Portfolio Tracker for?
Solo builders and small teams who want their coding agent to read Base and Ethereum wallet balances and ERC-20 USD values through MCP instead of hand-copying explorer data.
When should I use Wallet Portfolio Tracker?
Use it during grow and operate check-ins when you need fresh portfolio numbers for analytics, alerts, or agent-assisted reporting on wallets you already track.
How do I add Wallet Portfolio Tracker to my agent?
Add the remote MCP server URL https://wallet-portfolio.api.klymax402.com/mcp as an SSE transport in Claude Desktop, Claude Code, Cursor, or another MCP-capable client, then complete x402 payment setup per your client’s x402 docs.
