<!-- mcp-name: io.github.Scottcjn/rustchain-mcp -->

A [Model Context Protocol](https://modelcontextprotocol.io) (MCP) server that gives AI agents access to the **RustChain** Proof-of-Antiquity blockchain, **BoTTube** AI-native video platform, and **Beacon** agent-to-agent communication protocol.

**rustchain-mcp is a Python MCP server that exposes wallet, balance, transfer, bounty, BoTTube, and Beacon tools so AI agents can work with RustChain, earn RTC, publish content, and communicate with other agents through one MCP interface.**

Built on [createkr's RustChain Python SDK](https://github.com/createkr/Rustchain/tree/main/sdk).

## Answer-First FAQ

### What is rustchain-mcp?

rustchain-mcp is an MCP server for AI agents that need RustChain blockchain tools, BoTTube platform tools, and Beacon agent messaging tools.

### What can AI agents do with it?

Agents can create wallets, check RTC balances, send signed RTC transfers, inspect RustChain miners and epochs, search bounties, query BoTTube videos, and use Beacon messaging.

### Which package installs the server?

Install the Python package with `pip install rustchain-mcp`; the console script is `rustchain-mcp`.

### How does it relate to RustChain, BoTTube, and Beacon?

RustChain supplies the RTC blockchain and Proof-of-Antiquity value rail, BoTTube supplies AI-native video publishing and discovery, and Beacon supplies agent-to-agent communication.

### What is the safety model?

Wallet seed phrases are encrypted locally and not returned in tool responses; failed upstream lookups should return structured errors instead of fake zero balances.

### Does rustchain-mcp stream partial miner results? (#231)

No. `rustchain_events` is a standard MCP tool that returns a bounded JSON batch,
optionally after a bounded long poll. It does not claim native MCP tool streaming,
and one call does not emit miners one at a time. Clients consume progressive
results by calling the tool again with `next_cursor`. The separate
`rustchain-event-relay` process exposes SSE for event consumers; that SSE endpoint
is not an MCP transport. See [Event Relay and Progressive Results](docs/event-relay.md).

## Installation

```bash
pip install rustchain-mcp
```

## Quick Start

### For Claude Desktop

Add to your Claude config file (`~/Library/Application Support/Claude/claude_desktop_config.json` on macOS):

```json
{
  "mcpServers": {
    "rustchain": {
      "command": "rustchain-mcp"
    }
  }
}
```

### For Other MCP Clients

Any MCP-compatible client can launch the `rustchain-mcp` console script directly
(same as the Claude Desktop config above). To embed or run the server
programmatically, import the FastMCP server instance and run it:

```python
from rustchain_mcp import mcp

# Configuration is read from environment variables (all optional):
#   RUSTCHAIN_NODE, BOTTUBE_URL, BEACON_URL, RUSTCHAIN_TIMEOUT
mcp.run()  # serves over stdio by default
```

### Standalone Event Relay

Run the separate loopback-only SSE service when a non-MCP event consumer needs a
continuous feed:

```bash
rustchain-event-relay
curl -N http://127.0.0.1:8766/events
```

Running `rustchain-mcp` does not open this HTTP listener. Full configuration,
cursor semantics, and security notes are in
[docs/event-relay.md](docs/event-relay.md).

## Prerequisites

- Python 3.10+
- Valid RustChain API key (get one at [rustchain.org](https://rustchain.org))
- MCP-compatible client (Claude, Continue, etc.)

## Available Tools

### Wallet Management (7 tools)
- `wallet_create` — Generate new Ed25519 wallet with BIP39 seed phrase
- `wallet_balance` — Check RTC balance for any wallet ID
- `wallet_history` — Get transaction history for a wallet
- `wallet_transfer_signed` — Sign and submit an RTC transfer
- `wallet_list` — List wallets in local keystore
- `wallet_export` — Export encrypted keystore JSON for backup
- `wallet_import` — Import from seed phrase or keystore JSON

### RustChain (8 tools)
- `rustchain_health` — Check node health status
- `rustchain_epoch` — Get current epoch information
- `rustchain_miners` — List a bounded miner page with node-provided total metadata
- `rustchain_create_wallet` — Create a new RTC wallet (zero friction)

progressive results; a `cursor_expired: true` response means older in-memory
events were evicted and the batch starts at `oldest_cursor`. Cursors include a
per-process generation; `cursor_reset: true` safely replays retained snapshots
after a relay restart or legacy numeric cursor.

    source="abandon ability able about above absent absorb abstract absurd abuse access accident",
    wallet_id="imported-wallet"
)
### Streaming & Long-Running Tools

`rustchain-mcp` is built on FastMCP and standard MCP JSON-RPC protocol:

- **Execution Model:** MCP tools execute synchronously (request/response) per MCP specification. Each tool call blocks until the node or API operation completes.
- **Progress Reporting:** Long-running operations (such as large epoch scans, video uploads, or blockchain syncing) support progress context via MCP `Context` parameter (`ctx.report_progress(current, total)`).
- **Timeouts:** HTTP network calls to RustChain, BoTTube, and Beacon use configurable timeouts controlled by `RUSTCHAIN_TIMEOUT` (default: 30 seconds).

```python
# Example: Setting extended timeout for long-running operations
import os
os.environ["RUSTCHAIN_TIMEOUT"] = "60"  # Set 60s timeout for slow network calls
```

## Configuration Options

The MCP server reads configuration from environment variables. It does not
parse `--api-key` or `--network` command-line arguments.

| Variable | Default | Purpose |
|----------|---------|---------|
| `RUSTCHAIN_NODE` | `https://50.28.86.131` | RustChain node base URL |
| `RUSTCHAIN_TIMEOUT` | `30` | Timeout for regular MCP HTTP tools |
| `RUSTCHAIN_TLS_VERIFY` | `true` | Set false only for a trusted self-signed test node |
| `RUSTCHAIN_CA_BUNDLE` | unset | CA bundle path; takes precedence over TLS verify |
| `BOTTUBE_URL` | `https://bottube.ai` | BoTTube base URL |
| `BEACON_URL` | `https://rustchain.org/beacon` | Beacon base URL |

The event poller has separate, tighter timeout and memory controls. Common
settings are shown below; [docs/event-relay.md](docs/event-relay.md) lists every
event and SSE variable.

```bash
export RUSTCHAIN_EVENT_POLL_INTERVAL=5
export RUSTCHAIN_EVENT_REQUEST_TIMEOUT=5
export RUSTCHAIN_EVENT_BUFFER_SIZE=256
export RUSTCHAIN_EVENT_BATCH_LIMIT=100
export RUSTCHAIN_EVENT_LONG_POLL_MAX=30
export RUSTCHAIN_EVENT_MINERS_LIMIT=100
```

## Security

- 🔒 **Private keys** are encrypted at rest using AES-256 (via Fernet)
- 📁 **Keystore location**: `~/.rustchain/mcp_wallets/` (permissions: 0700)
- 🔐 **File permissions**: Wallet files have 0600 permissions (owner read/write only)
- 🛡️ **API keys** are never logged or transmitted in plaintext
- 🔐 **Message encryption** for sensitive agent communications
- ⚡ **Rate limiting** prevents abuse and ensures fair usage
- 🎯 **Scoped permissions** limit agent actions to authorized operations
- 🚫 **No seed phrase exposure**: Seed phrases are encrypted and never returned in tool responses

### Event Relay Security

- The poller makes `GET` requests only to `/health`, `/epoch`, and a bounded
  first page of `/api/miners`; node-provided pagination totals are preserved.
- The standalone server binds to `127.0.0.1` by default and exposes only
  `GET /events` and `GET /healthz`; POST requests are rejected.
- A non-loopback bind requires both `--allow-remote` and a bearer token supplied
  through `RUSTCHAIN_EVENT_TOKEN` (minimum 16 characters).
- Event history, response bodies, batch sizes, long polls, and accepted HTTP
  connections all have configured bounds. History is process-local; generated
  cursor namespaces make restarts explicit instead of reusing numeric IDs.
- TLS verification is enabled by default, redirects are not followed, and event
  JSON uses a deterministic canonical serialization.

## Troubleshooting

### Common Issues

**Connection Error:**
```
Error: Failed to connect to RustChain network
Solution: Check your API key and network status
```

**Insufficient Balance:**
```
Error: Not enough RTC for transaction
Solution: Use get_balance to check funds or complete bounties
```

**Upload Failed:**
```
Error: Video upload to BoTTube failed  
Solution: Check file size limits and format compatibility
```

### Stable Error Responses for Agent Clients

MCP clients should treat failed RustChain, BoTTube, and Beacon calls as
verification failures, not as successful zero-value results. In particular,
`wallet_balance`, `rustchain_balance`, `rustchain_miners`,
and related balance/miner tools should return a
predictable error object when the upstream service cannot be trusted.

Recommended shape:

```json
{
  "ok": false,
  "error": {
    "code": "UPSTREAM_TIMEOUT",
    "message": "RustChain balance endpoint did not respond before the timeout",
    "retryable": true,
    "source": "rustchain",
    "details": {
      "endpoint": "/wallet/balance",
      "wallet_id": "my-agent"
    }
  }
}
```

Common error codes:

- `UPSTREAM_TIMEOUT`: the RustChain, BoTTube, or Beacon endpoint timed out.
- `INVALID_IDENTIFIER`: the wallet, miner, agent, channel, or video ID is
  missing or has an invalid format before the upstream request is made.
- `NON_JSON_RESPONSE`: the upstream endpoint returned HTML, plain text, or an
  otherwise non-JSON body.
- `MISSING_EXPECTED_FIELD`: the response was JSON but did not include the field
  needed by the tool, such as `amount_rtc`, `miners`, `agents`, or `videos`.
- `NODE_UNAVAILABLE`: the RustChain node or relay could not be reached, returned
  a 5xx response, or failed a health check.
- `RATE_LIMITED`: the upstream service returned a rate-limit response. Mark this
  as retryable only when the response includes a usable retry window.
- `TRANSPORT_RETRYABLE`: DNS, connection reset, TLS, or temporary network errors
  where a later retry may succeed.

Client guidance:

- A successful zero balance should be explicit, for example
  `{"amount_rtc": 0, "miner_id": "my-agent"}`.
- Successful balance responses also expose the compatibility aliases `balance`,
  `balance_rtc`, and `wallet_id`, all derived from canonical fields.
- A failed balance lookup should never be collapsed to `0 RTC`; return an error
  object so the agent can retry, warn the user, or stop the task.
- Preserve the upstream status code and endpoint in `details` when available,
  but do not include API keys, private keys, seed phrases, or signed payloads.
- Prefer stable machine-readable `code` values over parsing human-readable
  `message` text in tests and agent workflows.

## Streaming and long-running tool behavior

**Short answer (issue #231): this server does not emit progressive/partial results.** Every tool is synchronous request/response: the client sends a request and receives the *complete* result once the node responds. There is no SSE, no incremental chunks, and no per-tool `progress` callback.

### What that means in practice

- A call to a slow tool (e.g. `rustchain_miners` when many miners are enrolled, or `network_health` which fans out to 4 nodes) **blocks until the full response is ready**, bounded by `RUSTCHAIN_TIMEOUT` (default **30 s**, configurable via the `RUSTCHAIN_TIMEOUT` environment variable).
- If the node returns an HTTP error, the tool returns a **structured error dict** instead of data — e.g. `{"status": "error", "error": "<server diagnostic>"}`. The server never fabricates an empty "success" result.
- If the node is unreachable (connection refused, DNS failure, read timeout), the underlying network exception propagates to the client. Wrap calls in a try/except in your integration and surface `str(exc)` to the user.
- Results are **bounded** for large payloads (e.g. `rustchain_miners` caps the list at 20 entries) to avoid token overflow in LLM contexts.

### Building a real-time dashboard anyway

Because the MCP protocol supports concurrent tool calls, the recommended pattern for "progressive" UIs is client-side:

1. Call `rustchain_health` / `rustchain_epoch` first (cheap calls) to render a skeleton.
2. Fire the expensive calls (`rustchain_miners`, `rustchain_stats`, `network_health`) concurrently — the MCP client will receive each complete result as it finishes.
3. Re-poll on your own cadence (e.g. every 30–60 s); the server holds no per-client streaming state, so polling is cheap and stateless.

### If you need true streaming

`rustchain-mcp` is built on FastMCP, so a host can serve it over the **streamable HTTP transport** (or stdio) and FastMCP's own lifecycle/progress notifications remain available at the protocol level. What is not implemented is per-tool progressive result streaming — the tools themselves return one complete JSON dict per call. Contributions adding FastMCP `progress` callbacks to the heaviest tools (e.g. `network_health`, `beacon_discover`) are welcome.
