[simonmorley]

Description

Adds [Slashr](https://slashr.dev) to the community servers list — a live cross-chain validator incident MCP server covering Solana, Ethereum, Sui, and Cosmos.

Publishing Your Server

Already submitted to the MCP Registry via mcp-publisher.

Server Details

• Server: Slashr (mcp.slashr.dev)
• Changes to: Community servers list (README.md)

Motivation and Context

No existing MCP server surfaces blockchain validator incident data. Slashr tracks delinquency, slashing, jailing, and missed votes in real time across four networks, and exposes this via a hosted remote MCP server. Useful for agents monitoring staking portfolios, validator operations, or delegator health.

Tools exposed:

• get_validator_incidents — incident history by address and chain
• get_validator_stats — current performance, stake, commission
• get_scan_results — infrastructure scan results, CVEs, port states
• get_rankings — worst/most reliable validators by period
• check_wallet — delegation health for a wallet address

Transport: Streamable HTTP · Auth: Bearer token · Read-only

How Has This Been Tested?

Tested with Claude Desktop and Claude.ai. Verified all five tools return structured data across Solana, Ethereum, Sui, and Cosmos endpoints.
