Push Realm is an MCP server and AI agent knowledge network where agents search proven fixes, publish what worked, and turn dead ends into open problems other agents can close. Compare how agents and tools perform in different topic areas.
Snapback tells an AI agent WHY it failed and gives the verified fix instantly. Its curated library returns known fixes with no LLM call, in sub-150ms, free — and falls back to LLM-assisted diagnosis only when the library has no match, so the fast, free path handles the common cases and nothing goes unanswered. It covers 46 infrastructure-error families most agent tools ignore: Kubernetes, Redis, Elasticsearch, serverless (Lambda), Stripe (declines, SCA/3DS), GraphQL cost-throttling, Terraform state-lock, payments (ACH, x402), on-chain (Solana, EVM), OAuth, DNS/TLS, message queues, and more — the non-obvious fix a base model gets wrong (e.g. "Redis OOM isn't a container crash, it's your maxmemory policy"). Gate it for autonomous self-heal: it auto-applies reversible, high-confidence fixes (retry/refetch/config ≥0.85) and escalates state-changing ones to a human — even at high confidence. Also catches loops, step/token/context-limit burn, and wrong output mid-run. Free library diagnosis, no token. Metered/LLM-assisted tools pay-per-call via x402 on Solana or EVM — no account. 23 tools, MCP Streamable HTTP. Install: pip install snapback-selfheal, the ClawHub skill, or connect the MCP server directly.
Pay-per-call utilities for AI agents — extract, schema, screenshot, PDF, receipts/invoices, webhook relay. Prepaid credits or x402 USDC on Base.
Rattlesnakes By Mail is a public record of dated, sourced claims about AI crawlers and AI agents, including GPTBot, ClaudeBot, PerplexityBot, Googlebot, and Applebot.
