[mangrove-one]

Description

Adds the Mangrove Wallet MCP plugin (skills/wallet-mcp/plugins/mangrove.md, version 0.1.0, hybrid, Base).

Mangrove gives trading agents guardrails. Every order goes through built-in risk management: circuit breakers, drawdown and daily loss limits, automatic risk-based position sizing, and automatically generated stop-loss and take-profit orders. Behind that sit 100+ tools for strategy R&D across 12+ venues. Access: pay per call in USDC on Base via x402 through Wallet MCP, or a free API key.

Change type

• Skill workflow

Validation

• Example prices in the file were read from the live 402 header (GET /api/v1/crypto-assets/global-market amount 5000 = 0.005 USDC; GET /api/v1/market-data/regime/{asset} amount 20000 = 0.02 USDC) and the OpenAPI x-payment-info.
• python3 -m unittest discover -s tests passes on the branch (38 tests).
• Not run: the plugin-review skill (not in this repo checkout; the file was checked by hand against the plugin spec and authoring checklist), an authenticated Wallet MCP smoke test, signed commit.
• Diff is the plugin file only. The SKILL.md registry row and the spec conformance table are left to maintainers per the contribution scope.

Release considerations

Maintainers to add the SKILL.md registry row on acceptance.
