Your coding agent ships code. This is what checks it.
Describe a product or a feature. 72 agents with narrow jobs take it through brief, architecture, build, review and security; a second model from another family reads the same diff. Three decisions stay yours — what gets built, how, and whether it ships — and what lands is a repository you own and a URL that works. You pay your own LLM provider; great_cto is MIT and bills nothing.

Questions
What is the great-cto MCP server?
You already have the agent. This is everything around it. great_cto runs Claude Code as a pipeline of 70 specialist agents — an independent model checks each stage before the next builds on it, spending caps refuse rather than warn, and three decisions stay yours: what gets built, how, and whether i
What tools does great-cto expose?
9 in total: 9 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is great-cto safe to connect to an agent?
No — not without reading the findings first. The audit graded it F (22/100) and found 12 critical or high issues in the source. Each one is listed on this page with the file and line it is on.
What credentials does great-cto need?
It reads ANTHROPIC_API_KEY, BENCHMARK_TEST_SECRET, GREAT_CTO_DISABLE_SECRET_SCAN, GREAT_CTO_FIXTURE_HMAC_KEY, GREAT_CTO_TEST_CREDENTIAL, LLM_INPUT_TOKENS, LLM_OUTPUT_TOKENS and OPENROUTER_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How current is this page?
The grade is for one exact copy of the source (27dfe0a0e870), read on 2026-10-12. The repository is watched and re-audited when it changes.
