Hive Vault

srotzin/hive-mcp-vault MCP server

MCP access to confirmed HiveVault FENR reads and an AES-256-GCM encrypted item store.

Live contract

The server exposes four read-only MCP tools backed by the live HiveVault service:

Tool	Live backend route
vault.balance	GET /vault/balance
vault.stats	GET /vault/stats
vault.identity	GET /vault/identity
vault.quantum_pubkey	GET /vault/quantum/pubkey

vault.balance returns the backend response exactly as received. An unauthenticated response can be marked obfuscated: true; clients must not treat that value as a confirmed treasury balance.

The server also exposes an encrypted item store:

Method	Path	Description
POST	/v1/vault/store	Store an AES-256-GCM encrypted item after the x402 gate
GET	/v1/vault/store/:item_ref	Confirm a stored item exists without returning plaintext

Unknown paths return HTTP 404. Upstream failures return explicit MCP errors. The service does not return fabricated success payloads.

Discovery and health

Method	Path	Description
GET	/health	Local liveness and current upstream reachability
POST	/mcp	MCP JSON-RPC 2.0, protocol 2024-11-05
GET	/.well-known/mcp.json	MCP discovery manifest
GET	/.well-known/agent-card.json	A2A agent card
GET	/.well-known/agent.json	Agent card
GET	/.well-known/oac.json	Open Agent Card JSON-LD
GET	/llms.txt	Plain-text integration guide

Persistence

Set BOGO_DB_PATH to a path on durable storage in production. The default path, /tmp/bogo_vault.db, is suitable only for local development and tests. The server refuses to start in production unless an explicit database path is configured.

Environment variables

Variable	Required	Purpose
PORT	No, default 3000	HTTP port
VAULT_BACKEND_URL	No, default https://hive-vault.onrender.com	Live HiveVault backend
INTERNAL_KEY	Yes in production	Derives the local encryption key and is sent to the backend as x-vault-key
BOGO_DB_PATH	Yes in production	SQLite database path on durable storage. Local development defaults to /tmp/bogo_vault.db
BASE_RPC_URL	No, default https://mainnet.base.org	Base RPC endpoint used for x402 payment verification

The server refuses to start with NODE_ENV=production if INTERNAL_KEY or BOGO_DB_PATH is missing.

Testing

npm install
npm test

Tests cover health reporting, unknown-route handling, MCP tool discovery, upstream failure behavior, encrypted storage, and plaintext absence from the SQLite file.
