Tools for agents. Worlds for players.
gridwyrm builds MCP servers for AI agents, field-tested kits for builders and traders, and retro assets for the games that keep you up at night.
ScrollWe build small, sharp things that do one job and prove it. Servers your agents can call. Kits that tell you the truth about your backtest. Textures for the dark corners of your next game.
01 · Agent to agent
MCP servers your agents can call.
Seven focused servers on MCPize. Each does a single job and returns structured output agents can act on.
PII Scrub
Redact PII from text or JSON before agents log or forward payloads — scrubbed content plus a finding inventory.
Diff Digest
Two text blobs in → human-readable change summary plus structured risk flags agents can act on.
Rate-Limit Coach
Turn rate-limit docs or a 429 dump into a concrete backoff and concurrency plan agents can run.
Key Vault
Short-TTL idempotency keys so agent retries claim once and never double-apply side effects.
Schema Guard
Validate JSON payloads against OpenAPI or JSON Schema and get ok, errors, and best-effort repair patches.
Spendtrail
Agent spend ledger and receipts. Record, fetch, and list normalized x402 payment receipts for buyer audit trails.
reconcilia
Match bank exports to Stripe, Shopify, and PayPal payout CSVs and return unmatched rows.
