You need dedicated capabilities in the Finance & Fintech domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: API Key required (BYOK (Pay Provider Direct)).
PayPerByte — per-byte data marketplace for AI agents on Arbitrum. Discover publishers, evaluate on-chain Proof-of-Quality Score (PQS), subscribe + pay per request in USDC via x402 gateway. 15 tools, zero API keys.
AI inference via MCP — pay per request with Solana USDC through x402. No API keys.
Search PayPerByte publishers by topic and sort order. Returns publisher addresses, topics, subscriber counts, message counts, and price-per-KB.
byte_get_publisher
Get on-chain info for a specific PayPerByte publisher: status, subscriber and message counts, USDC revenue, and the registered schema (size bounds, cadence, price-per-KB).
byte_get_network_stats
Get PayPerByte network-wide statistics: total publishers, messages streamed, and total subscriber fees settled in USDC.
byte_check_subscription
Check if an address is subscribed to a specific publisher on PayPerByte.
byte_get_token_balances
Get USDC and ETH balances for an address on Arbitrum Sepolia (the on-chain testnet layer — MockUSDC settles subscriptions and fact-oracle queries there). Does NOT show the Base-mainnet USDC balance that byte_buy_data spends.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Byte Mcp Server is categorized under Finance & Fintech and uses a local stdio subprocess. In contrast, BridgeNode MCP belongs to Finance & Fintech using local stdio subprocess. Select Byte Mcp Server when you need capabilities focused on finance & fintech and BridgeNode MCP when you require tools for finance & fintech.
List all active data feeds in the PayPerByte catalog with topics, price-per-KB, and frequency.
byte_list_my_subscriptions
List every active subscription for a given wallet address. Each entry has the publisher address, topic, status, when you subscribed, messages received in 7/30 days, USDC spent in 7/30 days, and the timestamp of the last message received. Use this to see what you're currently paying for and decide whether to unsubscribe.
byte_subscription_health
Get the content-drift signal for a publisher. Compares their last 7 days of publishing activity (cadence, message count) against their 23-day baseline (days 8-30). Returns 'stable' (steady publishing), 'moderate' (20-50% cadence shift or 24-48h silence), 'significant' (>50% shift or >48h silence), or 'unknown' (new publisher, insufficient baseline). Use this to detect when a publisher you subscribe to has pivoted content or gone dormant.
byte_unsubscribe
Unsubscribe from a publisher's data feed. Takes effect next block: no more billing, no more data flow. Reversible — you can resubscribe later via byte_subscribe. Use this when a publisher has pivoted content (check with byte_subscription_health first) or when you simply don't want the feed anymore. Requires PRIVATE_KEY for the connected wallet.
byte_subscribe
Subscribe to a PayPerByte publisher's data feed. By default also sets USDC allowance to DataStreamLib to type(uint256).max so the subscription doesn't silently lose payments when allowance depletes (the contract's allowance-skip path emits DataStreamed with amount=0 on transferFrom failure rather than reverting). Pass skipAllowance: true to opt out and set a finite cap manually. Requires PRIVATE_KEY.
byte_register_publisher
Register as a data publisher on PayPerByte. Registers a schema and the publisher on-chain. Requires PRIVATE_KEY. PayPerByte v1 publishers are first-party and unstaked — leave stake at '0'; a non-zero USDC stake is approved to DataRegistry first if you choose to post one.
byte_publish_data
Publish data to a subscriber via the PayPerByte DataStream contract. Hashes the payload, records size on-chain, and settles the fee in USDC. Requires PRIVATE_KEY.
