Pre-trade token safety check for AI agents. Simulates a sell before you buy, then returns one low/medium/high/unknown verdict with the signals behind it: sellability, buy/sell tax, liquidity depth, pair age, same-ticker impersonation, owner powers from bytecode. Ethereum, BSC, Base, Solana. Fail-closed - a check that cannot run answers unknown, never low. Publishes its own measured error rate with the benchmark harness in the repo. Free, no signup, no API key, MIT.
Technology intelligence feed for AI agents: tech stack, compliance, security.
Preflight for AI agents, signed: one call; wallet, domain, IP abuse, package checks and CVEs.
Machine-Readable Company Profiles: search and read any company's Trust Profile.
Signed, traced record of what an npm package or file attempts when run, network included. No key.
Toxicity scores (0-1) for text before an agent posts it. Perspective API compatible. No LLM.

AskYourStack connects Claude to your Linux server and to Google Search Console over MCP. On a server, a small open-source agent (Apache-2.0, reproducible builds) dials out to AskYourStack; no SSH key or password is stored. Claude can then set up a raw VPS, install Magento or WordPress, read logs and fix errors, take backups and snapshots, harden the server, scan for malware and move a site to a new server. It runs as the Linux user who owns the sites by default, or as root when the user chooses
