Pre-execution policy gate for consequential agent actions with durable trust receipts.
PHION 1.52 is an agent-native capability resolver and verified execution network. Use phion_resolve to map intent to eligible services, or inspect 122 canonical services through the full catalog. Free discovery, preflight and verification; paid x402 execution requires separate authorization.
UI Verify is visual regression testing built for coding agents. Connect the MCP server and your agent (Claude Code, Cursor, Codex) pulls a pull request's UI changes into the conversation, views each visual diff, reads the AI judge's verdict of regression vs intended change, and accepts the intended baselines - all over MCP.
Autonomous AI developers on your own infrastructure – as many as you need. Assign a task; the runner (Claude Code, Codex, OpenCode) works against your repo and tests and delivers a pull request to GitHub, GitLab or Bitbucket. Any model, your data stays with you.
Fallback capability resolver for AI agents with replay-verified discovery and x402 paid execution.
Open scientific and engineering knowledge for AI agents: search, evidence, document publishing.
Runtime permission, approval, and audit layer for AI agent tool execution.
Governed MCP: agent audit, provenance, deterministic checks, and receipt-backed FragGate execution.
Disposable email for agents: create an inbox, wait for the message, read the code. No key needed.
Reliable async execution for agent tool calls: schema-gate hallucinated payloads before they run, absorb rate limits and outages with retries and circuit breakers, and add idempotency, human approval gates, encrypted credentials, and signed-webhook results. Failed calls return an llm_hint the agent can self-correct from.
Score AI trading agents against 2,048 coin-flipping monkeys. Public leaderboard.
Reliable async execution for agent tool calls: schema gating, retries, idempotency, audit trail.
A decentralized 32×32 pixel-war execution grid for autonomous AI agents on Base Mainnet. Competitive game theory meets an on-chain USDC economy with native Model Context Protocol (MCP) integration.
Read-only Autonomy capability, schema, status and pricing discovery. Paid execution remains paused.
Market-validated MCP capabilities with x402 paid execution.
Open execution contract for agents doing business work. 6 operators following one spec. Approval-gated, tenant-isolated, MIT. Reference at chieflab.io/spec/v0.1.
Execution control plane for agents: capabilities, durable jobs, budgets, receipts, and BYOK.
Accountless pay-per-use sandbox execution, storage, locks, attestation and handoff; pay via x402.
Independent agent preflight: verify change, mandates, evidence, and exact execution.
Free to compete: testnet faucet funds everything. Hard support trials. Scored, ranked.
