Review signals: 1 connection review.

Reviewed as expected for a test run: attempted writes that failed, so nothing was written.

Repository processes attempted these non-loopback connections; proxies can hide the final hostname. 187.124.23.59:443 5 attributed processes.

OSV scanned supported lockfiles; unpinned dependencies and unsupported formats are outside this check.

A short run cannot establish that code is safe.

Connections show IP addresses; proxies can hide the final hostname.

Tracing covers dispatched commands and their children, not the whole OS; guest root can interfere with tracing.

• The handshake tool evaluates the request and returns a settlement receipt.: Real input produced the expected result: Zero-Knowledge Handshake successfully settled on Midnight Blockchain.

  Source: Evaluates tool execution parameters in ephemeral RAM, strips prompt injections, generates a cryptographic 32-byte intent commitment, and anchors state transitions gaslessly to Midnight.

  Input: {"tool": "rohan_zk_handshake", "arguments": {"agentId": "did:example:probe", "actionSummary": "valid request"}}

  Expected: successful result containing a settlement receipt

  Command: node packages/mcp/dist/server.js tools/call {"tool": "rohan_zk_handshake", "arguments": {"agentId": "did:example:probe", "actionSummary": "valid request"}}

  Observed: Zero-Knowledge Handshake successfully settled on Midnight Blockchain.\",\n \"receipt\": {\n \"success\": true,\n \"status\": \"confirmed\",\n \"contractAddress\": \"585ac0c4448257507d8ffa2a89e2aa00abd86ec9e94bdb6f553bc83e05f4dd0e\",\n \"intentHash\": \"4e33ba77a0a026a6018bcb3557b42377dab2a4542d4c79bf55998835d6a5cf88\",\n \"txHash\": \"0x000e6086cb3af191f20e1a421c3a42c00ade3f614d54910714a39185bbe1974b8c\",\n \"gasPaidBy\": \"rohan-relayer-node-01\",\n \"engine\": \"Midnight Network L1 (Blockfrost Preprod Mined)\",\n \"timestamp\": 1792970476092\n }\n}"}]}

Examples

• Install dependencies and build the documented source server.: command completed successfully

  Source: README.md, Running the MCP Server from Source

  Input: npm install; npm run build

  Expected: all workspaces build successfully

  Command: npm run build

  Observed: > [email protected] build > npm run build --workspaces --if-present > @rohan-protocol/[email protected] build > tsc && rm -rf dist/generated && cp -r src/generated dist/generated > @rohan-protocol/[email protected] build > tsc > @rohan-protocol/[email protected] build > tsc
