WalletWall MCP
OfficialProvides read-only lookup and inspection of stablecoin deployments on Ethereum by chain ID and address, including identity resolution, evidence and conflict inspection, provenance tracing, invariant checks, and vault-readiness signals from a bundled point-in-time registry.

That's it! The server will respond to your query, and you can continue using it as needed.

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
Part | What it is |
WalletWall (plugin) | The Copilot plugin in |
WalletWall MCP | A local, offline, read-only MCP server (stdio only) with six tools and eleven static resources. Exact contract: |
WalletWall (canvas) | A panel that shows one bundle: Sources, Support, Freshness, Conflicts, Limitations and "Why WalletWall says this", exactly as WalletWall MCP returned them |
Skill | Tells the model to report what the sources support, surface limitations and never over-claim |
Tool | Purpose |
| Registry lookup by chain ID + address, or symbol candidates. Symbols are never identity |
| Canonical observation, RFC 8785 + SHA-256 digests, exact decimal rendering |
| Support, freshness, finality, authority, limitations and conflicts per assertion |
| The 13 WWEP invariants plus declared-versus-computed |
| W3C PROV-JSON-shaped source lineage for one assertion |

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@walletwallOr from a local checkout:
copilot plugin marketplace add <path to this checkout>
copilot plugin install walletwall@walletwallThe 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 8787It 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 verifyGenerated files are committed and verified in CI on Linux and Windows. See CONTRIBUTING.md for which command regenerates what.
