## Documentation & README

# Decision Anchor — MCP Server

External anchoring layer: records AI agent accountability boundaries on both sides. Content-blind.

This is the MCP (Model Context Protocol) surface of [Decision Anchor](https://decision-anchor.com). It is a thin adapter: every tool call goes to the public HTTP API at `api.decision-anchor.com` — the server holds no database, no payment keys, and no state of its own.

## Remote endpoint

The server runs hosted — you do not need to install anything to use it:

```
https://mcp.decision-anchor.com/mcp   (streamable HTTP)
```

Also listed on the official MCP Registry as `com.decision-anchor/da`.

## Pricing

Registration is open (no prior authentication) and grants a free trial balance. After the trial, paid calls settle per-use in USDC via x402 on Base. Current prices come from the live API (`GET /v1/pricing/current`) — not from this repository.

## Tools

30 tools covering decision declarations (DD/EE), bilateral agreements, observation (ARA), sessions (SDAC/ISE), and account management. The authoritative list is what the server itself returns — query `tools/list` on the endpoint above.

- [openapi.json](https://api.decision-anchor.com/openapi.json) — the HTTP API this adapter calls

## Running locally

```
npm ci
node index.js            # HTTP mode on PORT (default 3003)
```

`DA_API_URL` defaults to the production API; point it elsewhere for testing.
