Wallet4Agent

Wallet4Agent exposes a single MCP endpoint that acts as the core interface for all model context operations. You can use this endpoint to manage identity, issue and verify credentials, perform signing, and configure flows in a standardized, interoperable way. This MCP server abstracts complex cryptographic and identity workflows behind a simple, REST-like entry point that your client can call to drive trusted AI agent interactions.

How to use

To use the MCP server, point your MCP client at the designated endpoint and call the available tools through the MCP interface. Every operation is exposed as a tool, covering identity creation, credential issuance, verification flows, signing operations, and configuration. Your agent communicates with the MCP server to perform cryptographic signing, manage DID-based identities, publish linked verifiable presentations, and participate in OAuth2/OIDC-based credential workflows.

How to install

Prerequisites: ensure you have network access to the MCP endpoint and a standard HTTP client or library available in your environment.

Step 1: Prepare your MCP client configuration by defining the MCP endpoint URL: https://wallet4agent.com/mcp.

Step 2: Initialize your MCP client in your preferred language or toolset. You will use the single MCP endpoint to access all tools such as identity creation, credential issuance, verification, signing, and configuration.

Step 3: Authenticate to the MCP endpoint using one of the supported authentication methods. Typical options include a Personal Access Token, OAuth2 client credentials, or OAuth2 private_key_jwt, depending on your deployment and security requirements.

Configuration and usage notes

• The MCP server centralizes complex cryptographic and identity logic. Your agent simply calls MCP tools to perform operations. This keeps your agent lightweight while ensuring interoperability with standards such as OIDC4VCI, OIDC4VP, SD-JWT, JSON-LD, and OAuth2.

• The MCP endpoint is the single access point for all MCP operations. Use this URL consistently in your MCP client configuration and in any integration layer that needs to drive credential issuance, verification, or identity management.

Security considerations

• Security sits at the MCP layer, with signing keys managed by cloud KMS-backed solutions and non-exportable private keys. Your agent’s operational security should complement this by ensuring secure execution environments and proper access controls.

• Authentication to the MCP server should be tightly controlled. Prefer strong authentication methods such as OAuth2 private_key_jwt for enterprise deployments.

Troubleshooting tips

• If calls to https://wallet4agent.com/mcp fail, verify network reachability, DNS resolution, and TLS configuration. Check that your MCP client is sending valid authentication credentials and that the endpoint is accessible from your environment.

• Review credential issuance and verification workflows for proper issuer metadata, token exchange, and presentation formats to ensure compatibility with OIDC4VCI and OIDC4VP flows.

Notes on capabilities

Wallet4Agent provides tools for: identity creation, credential issuance, verification flows, signing operations, and configuration. These tools enable you to manage a DID-based identity, issue and verify verifiable credentials, publish linked presentations, and manage OAuth2/OIDC-based interactions in a secure, interoperable way.

Available tools

identity_create

Create a new agent identity and DID document within the MCP workflow.

credential_issuance

Handle issuance flows for verifiable credentials (OIDC4VCI) including token exchange and proof creation.

verification_flow

Coordinate verification processes (OIDC4VP) and manage status polling and attribute derivation.

signing_operations

Perform cryptographic signing tasks using KMS-backed keys for attestations and proofs.

configuration

Manage MCP configuration including authentication methods, policies, and integration settings.
