Build on Slashr

MCP

Connect your AI agent to live validator incident data via the Model Context Protocol. Query delinquency, slashing, scan results, and delegation health across every network we track.

Tools

get_validator_incidents

Get incident history for a validator. Returns delinquency, slashing, and jailing events with timestamps and severity.

address · chain · days · limit

get_validator_stats

Get current performance and staking data for a validator. Chain-specific metrics including delinquency frequency, epoch credits, stake, commission.

address · chain

get_scan_results

Get the latest infrastructure scan results for a validator. Shows port states, service health, CVEs, and diagnosis.

address · chain

get_worst_offenders

Get validators ranked by incident severity. The ‘hall of shame’ — who’s been the most unreliable.

chain · period · limit

check_delegation

Check the health of a delegator’s staked positions. Paste a wallet address, see which validators they’re staked with and how reliable each one is.

wallet_address · chain

get_network_summary

Get a high-level summary of validator incidents across a network. Total events, active incidents, top offenders.

chain · period

Chain accepts sol, eth, sui, or atom. Auto-detected from address format when omitted.

Every response includes both human-readable text and structured JSON.

Programmatic key generation

Agents that hit the MCP server without a token receive a JSON response explaining how to get one. The key generation endpoint is rate-limited to 1 key per IP per day.

# Request without auth → server tells you how to get a key
curl -X POST https://mcp.slashr.dev/mcp

REST API

Slashr also has a JSON REST API for direct integration: events, validators, rankings, delegation health checks, and more. Your API key works for both MCP and REST.

Feeds and dataset

No key required. Each feed is available as RSS, Atom and JSON Feed — swap the extension. Everything here is free to quote and excerpt with attribution.

/feed/slashing.rss — real penalties only, on the chains whose protocol reduces stake. Roughly 15 items a week. Start here.
/feed/stories.rss — one item per confirmed multi-validator incident rather than one per validator. Very quiet.
/feed/incidents.rss — everything, roughly 175 items a week and mostly routine downtime.
/data — the full event history as monthly CSV partitions, with per-chain coverage bounds and a dated release for each month. CC BY 4.0.

Building your own view? /v1/events takes severity, category, class and slashing filters, which is how the curated feed above is defined.

Slashr tracks validator incidents across 0 networks. Built by NullRabbit.
