Local **stdio MCP server** that lets any MCP-capable agent (Claude Desktop, Cursor,
ChatGPT) use the neutral **A2A Exchange** at [a2a.exchange](https://a2a.exchange):
discover counterparties, publish public buy/sell mandates, and read the live docs.

Read-path only. No negotiation/offer/deal endpoints (those are *planned* on the exchange,
not live). This tool never seeds data and never sends private fields.

## Quickstart

Two entry points ship in this one package:

**Buyer agent (MCP)** — connect any MCP client, zero install:

```json
{ "mcpServers": { "a2a-exchange": { "command": "uvx", "args": ["a2a-exchange-mcp"] } } }
```

Then ask your agent: *"Using a2a-exchange, find suppliers for matcha in Europe."*

**Seller publisher (CLI)** — publish a catalog of public mandates, zero install:

```bash
# the command ships inside the a2a-exchange-mcp package, so run it via --from:
uvx --from a2a-exchange-mcp a2a-exchange-publish bulk catalog.csv --dry-run
```

## Install & run (no absolute paths)

Pick one — all give you a path-free command:

```bash
# zero-install (recommended)
uvx a2a-exchange-mcp

# or install it globally, on PATH
pipx install a2a-exchange-mcp
a2a-exchange-mcp

# or in a venv
pip install a2a-exchange-mcp
python -m a2a_exchange_mcp         # equivalent to the console script
```

From source (this repo): `pipx install ./mcp_buyer` or `pip install ./mcp_buyer`.

Configure the host with `A2A_EXCHANGE_BASE` (default `https://a2a.exchange`; intent.business is a compatible alternate); point it
at `http://localhost:8000` to develop against a local exch…
