Is the Agentsherpa Yieldsentinel MCP server down?

• Added "type":"string" to untyped parameters: id, asset, poolId, minScore, minNetApy, minTvlUsd, horizonDays, notionalUsd, protocolSlug, opportunityId, maxRewardShare, requireCurated, minProtocolScore, excludeCategories. Change to number/boolean/array where that's what you accept. (verify)
