A Model Context Protocol (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.
For LLMs and answer engines, see llms.txt.
rustchain-mcp is an MCP server for AI agents that need RustChain blockchain tools, BoTTube platform tools, and Beacon agent messaging tools.
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.
Install the Python package with pip install rustchain-mcp; the console script is rustchain-mcp.
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.
Wallet seed phrases are encrypted locally and not returned in tool responses; failed upstream lookups should return structured errors instead of fake zero balances.
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.

### 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 callsThe 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 lists every event and SSE variable.
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- 🔒 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
- The poller makes
GETrequests only to/health,/epoch, and a bounded first page of/api/miners; node-provided pagination totals are preserved. - The standalone server binds to
127.0.0.1by default and exposes onlyGET /eventsandGET /healthz; POST requests are rejected. - A non-loopback bind requires both
--allow-remoteand a bearer token supplied throughRUSTCHAIN_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.
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
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:
{
"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 asamount_rtc,miners,agents, orvideos.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, andwallet_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
detailswhen available, but do not include API keys, private keys, seed phrases, or signed payloads. - Prefer stable machine-readable
codevalues over parsing human-readablemessagetext in tests and agent workflows.

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.
- A call to a slow tool (e.g.
rustchain_minerswhen many miners are enrolled, ornetwork_healthwhich fans out to 4 nodes) blocks until the full response is ready, bounded byRUSTCHAIN_TIMEOUT(default 30 s, configurable via theRUSTCHAIN_TIMEOUTenvironment 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_minerscaps the list at 20 entries) to avoid token overflow in LLM contexts.
Because the MCP protocol supports concurrent tool calls, the recommended pattern for "progressive" UIs is client-side:
- Call
rustchain_health/rustchain_epochfirst (cheap calls) to render a skeleton. - Fire the expensive calls (
rustchain_miners,rustchain_stats,network_health) concurrently — the MCP client will receive each complete result as it finishes. - 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.
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.
