ChiefLab

ChiefLab (chieflab.io) builds execution loops for agent-built companies: it gets users for products built with AI agents by choosing a daily growth move, drafting the post and assets, gating it on human approval, recording proof, measuring the result (e.g. Hacker News, Reddit, X, LinkedIn) and proposing the next action. It is distributed as a hosted MCP server at api.chieflab.io/api/mcp, an OpenAPI-described HTTP API, and npm packages @chieflab/cli, @chieflab/mcp-server and @chieflab/sdk, alongside an open MIT-licensed launch contract spec (v0.1). Its terms are governed by the laws of Singapore.

ChiefLab publishes 6 API contracts indexed on the APIs.io network, including Connectors API, GTM API, MCP API, and 3 more. Tagged areas include AI Agents, Growth Marketing, MCP, Product Launch, and Marketing Automation.

The ChiefLab catalog on APIs.io includes 1 Spectral governance ruleset.

ChiefLab’s developer surface includes CLI, sandbox, authentication, documentation, getting-started guide, API reference, pricing, and 41 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
