Walletwallrus Copilot MCP Server

WalletWall

Stablecoin intelligence and vault readiness for GitHub Copilot.

WalletWall is a local, read-only Copilot plugin and MCP server for inspecting stablecoin identity, source lineage, conflicts and vault-readiness signals.

Status: Pre-release
WWEP: 0.1
Registry: point-in-time verified

WalletWall does not sign, custody, trade, broadcast transactions, provide investment advice or certify regulatory compliance. Nothing here has been published to npm or a Copilot marketplace. Source and release artifacts are on GitHub Releases (v0.2.0), and the local MCP server's metadata is listed in the official MCP Registry as io.github.Wallet-Wall/walletwall.

Inspect stablecoin identity, wallet state, source lineage, conflicts, and vault readiness through WalletWall MCP.

What you get

What it will not say

A support state such as ESTABLISHED means the presented evidence satisfies a published policy. It does not mean the evidence is true.

WalletWall reports what identified sources and authority policies support. A supported result does not guarantee that upstream information is correct.

The bundled registry (five stablecoin deployments on Ethereum, Base and Arbitrum) is a point-in-time snapshot verified on 2026-10-24. It is not live or current-chain data. WalletWall fetches nothing at runtime. See docs/REGISTRY_SOURCES.md.

Privacy

WalletWall-controlled code does not retain MCP query history or transmit query data to WalletWall infrastructure. GitHub Copilot and the selected model provider may independently process prompts and tool data under their own policies.

Wallet addresses you put in a prompt are processed by Copilot and the model provider, not by WalletWall. Details and the limits of what is tested: PRIVACY.md, docs/PLUGIN_PATH_PRIVACY.md.

Install

From this repository on GitHub (verified with GitHub Copilot CLI 1.0.103 against the public repository, with no credentials):

copilot plugin marketplace add Wallet-Wall/walletwallrus-copilot
copilot plugin install walletwall@walletwall

Or from a local checkout:

copilot plugin marketplace add <path to this checkout>
copilot plugin install walletwall@walletwall

The marketplace and the plugin are both named walletwall. Verified with GitHub Copilot CLI 1.0.103: copilot plugin list --json reports walletwall from marketplace walletwall, version 0.2.0. This repository is the plugin source only; the plugin is not an accepted listing in any GitHub or Copilot marketplace or catalog. The official MCP Registry listing covers the MCP server's metadata only and is discovery, not endorsement or certification.

In the GitHub Copilot app: Customize → Plugins → marketplace settings → add this repository → Install. A new session then has the six WalletWall MCP tools, the skill and the WalletWall canvas. What was verified on Windows and what was not: docs/DESKTOP_INSTALL_PROOF.md. Requires node on PATH.

Claude Managed Agent (optional)

The shipped Copilot MCP remains stdio-only. For a user-owned Claude Managed Agent, a separate opt-in loopback Streamable HTTP adapter is available from a source checkout:

node scripts/claude-mcp-http.ts --port 8787

It exposes http://127.0.0.1:8787/mcp for connection through the user's own Anthropic MCP tunnel. The adapter lives outside the packages/mcp publish surface, is not part of the bundled Copilot runtime, does not create a WalletWall-hosted endpoint, and does not change the six-tool WalletWall MCP contract. See docs/CLAUDE_MANAGED_AGENT.md.

Develop

Requires Node.js 22.18 or newer (tested on 24).

npm ci
npm run verify

Generated files are committed and verified in CI on Linux and Windows. See CONTRIBUTING.md for which command regenerates what.
