Hive Mcp Barter
by srotzincommunityv1.0.0
An MCP server that scans public registries for 402-enabled endpoints, probes their quote prices, and can generate and settle single-shot pre-signed counter-offers on Base using USDC. It exposes discovery, quote-curve, and P&L tools plus REST endpoints for discover, probe, counter, settle, and ledger operations.
From the registry: Multi-party agent barter — non-cash capability exchange with cryptographic receipts
Install & configure

Install in your client
Paste into the AI you're chatting with — it will figure out the rest
Please install the `hive-mcp-barter` MCP server into my current AI client (that's you).
Optional prerequisites:
- Install Node.js and npm — Needed to run the local server or use npx-based MCP client connectivity. (https://nodejs.org/)
Canonical MCP server config (HTTP transport):
- url: `https://hive-mcp-barter.onrender.com/mcp`
Note: README describes an MCP server using Streamable-HTTP with POST /mcp and provides a client connection example via mcp-remote. The simplest portable client connection is the remote HTTP endpoint rather than running from source. Local self-hosting is also documented via git clone, npm install, and npm start. Relevant server env vars for self-hosting: PORT (optional, default 3000), ENABLE_OUTBOUND (optional, default false), WALLET_ADDRESS (optional), USDC_BASE (optional), BASE_RPC (optional), HIVECOMPUTE_URL (optional), MAX_DAILY_SPEND_USD (optional), MAX_SINGLE_COUNTER_USD (optional), COUNTER_PCT (optional), PRIVATE_KEY (required only to sign and place real counter-offers; without it, counter responses are unsigned and outbound bidding cron will not place real bids).
Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.Note: README describes an MCP server using Streamable-HTTP with POST /mcp and provides a client connection example via mcp-remote.
