Overview

AI-generated overview

Lets an assistant run cross-border data compliance preflight, read market and tool-catalog data, and get x402 quotes and audit records.

What you can do
Offers five tools: a cross-border data-flow preflight that checks a jurisdiction pair and data category against a local policy matrix and returns a verdict such as ALLOW, REVIEW or BLOCK; a read-only view of a daily scan of Asian and emerging-market companies and compliance signals; keyword search over a small static catalog of MCP tools; an informational x402 price quote for NOMOS services; and a lookup of local audit records by exact SHA-256 receipt hash.
When to use it
Use it when an agent needs a regulatory check before moving data across borders, or wants market, funding and compliance signals for Asian and emerging markets. Also useful for pricing NOMOS services or looking up local audit records by hash.
Requirements
Connects to a remote endpoint; no local package is needed. No authentication, environment variables or headers are declared. The market scan and audit lookup read local data files that a separate job must produce.
Before you install
The x402 quote is informational and unsigned, and includes a payTo address on Base mainnet and a USDC amount; confirm before any payment. The receipt tool is a record lookup by hash, not cryptographic signature verification. Preflight verdicts come from a local policy matrix and are not legal advice.

Installation

In SourceWeft

  1. Open NOMOS Cross-Border Broker in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.AgentNOMOS%2Fnomos-crossborder-broker/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Add this to your client's mcpServers config.

nomos_crossborder_preflight

Cross-Border Regulatory Preflight

Cross-border regulatory preflight for agent data flows. Checks jurisdiction pair (EU, JP, IN, KR, SG, CN, BR, NG, ZA, MX) and data category against a local policy matrix. Returns verdict: ALLOW / ALLOW_PUBLIC_SIGNAL_ONLY / REVIEW / BLOCK (or ERROR for unsupported input), plus blocked_fields, sccs_required, risk_level, matrix_coverage and evidence_hash. Local lookup only — no network access, no legal advice.

nomos_asia_market_scan

Daily Market Scan (Local Artifact)

Read-only view of the most recent local daily scan artifact covering 6 regions: Japan, Singapore/China, India, Korea, Brazil/LatAm, Africa. Returns MCP-ready companies, funded entities, compliance signals. The artifact is written once per day by a separate scanner job; this tool performs no live scanning and no network requests.

Parameterstaglimitregion

nomos_mcp_tool_discovery

OracleNet Tool Catalog (Static)

Search a small static curated catalog of OracleNet MCP tools by keyword and category. Returns tool names, endpoints, protocol support. Local data only — does not probe, crawl or contact any network endpoint.

Parametersqueryrequiredcategory

nomos_x402_quote

x402 Price Quote (Stateless, Unsigned)

Get a stateless, unsigned, informational x402 price quote for NOMOS services. Tier 1: $0.02 simple verdict | Tier 2: $0.05 verdict + evidence | Tier 3: $0.10 full packet. Returns payTo address, network (Base mainnet), amount in USDC atomic units, and a deterministic quote digest (not a signature). No payment is initiated and nothing is signed, persisted or reserved; expiry is informational only.

Parameterstierservicerequired

nomos_signed_receipt_verify

Receipt Record Lookup (Audit Log)

Look up a NOMOS operation record by its exact SHA-256 receipt hash in the local handshake audit log. Requires a full 64-hex hash, optionally 'sha256:'-prefixed; matching is exact against the stored receipt_hash/entry_hash fields. This is a record lookup, NOT cryptographic signature verification — the response always reports cryptographically_verified: false.
