Morpho

Lending and vaults on Base via Morpho CLI, with Morpho MCP fallback for chat-only surfaces.

Morpho is a lending protocol on Base. The plugin chooses the right execution path for the current environment: use the Morpho CLI (npx @morpho-org/cli@latest) in CLI-capable harnesses, and use the Morpho MCP server (https://mcp.morpho.org/) when the user is in a chat-only Claude or ChatGPT-style surface. Base MCP’s send_calls wraps prepared transactions into a single user approval.

Chain: Base mainnet.

Operations: deposit, withdraw, supply, borrow, repay, supply/withdraw collateral, plus reads for vaults, markets, and positions.

Environment-aware plugin. If the harness has shell or terminal access, use Morpho CLI. If it does not, use already connected Morpho MCP tools, or help the user install Morpho MCP for Claude or ChatGPT.

Install Morpho MCP when no CLI is available

Claude / Claude Desktop: Customize → Connectors → Add custom connector, name morpho, URL https://mcp.morpho.org/.

ChatGPT: Settings → Connectors → Create, name morpho, MCP Server URL https://mcp.morpho.org/, Authentication OAuth.

Pattern

In CLI-capable harnesses, run Morpho CLI:

npx @morpho-org/cli@latest query-vaults --chain base --asset-symbol USDC --sort apy_desc --limit 5
npx @morpho-org/cli@latest prepare-deposit --chain base --vault-address 0x... --user-address 0x... --amount 100

In chat-only harnesses, use Morpho MCP tools for the same vault/market reads and prepare actions. The assistant reviews the CLI JSON or MCP response (summary, transactions/calls, simulation status, outcome, and warnings), passes the unsigned calls to Base MCP send_calls with chain: "base", and polls get_request_status once you approve in Base Account.
