What the publisher says

From the Preflight repository's README, as published. We do not edit it. Read it on GitHub

skillfoundry-products

skillfoundry-products is the implementation repository for the probes, mechanisms, and offerings that Skillfoundry builds and operates.

Lifecycle: active. This monorepo is the canonical source for its maintained products, including Preflight.

Verified today: TypeScript workspace checks and both Python suites run through the root gate. Registry publication is separate and occurs only from pinned, checksum-verified OIDC workflows.

See docs/architecture.md for ownership boundaries, artifact roles, and dated migration exceptions.

This repo has two different lanes on purpose:

improve opportunities. These are not automatically public products.

  • mechanisms/: internal factory tools that help Skillfoundry identify, design, and

public deployment, distribution, and monetization.

  • products/: external, user-facing software artifacts that have been selected for
  • templates/: reusable implementation starters for future external product lanes.

Public product routing should stay platform-centric. The preferred external shape is:

  • https://skillfoundry.synaplex.ai/products//...

not one public hostname per product.

The distinction matters. Internal mechanisms help the agent system think and decide better. External products are what we eventually sell or distribute through channels such as AgenticMarket.

Default External Stack

The default lane for new external MCP offerings or probes is now:

  • TypeScript-first
  • remote MCP over Streamable HTTP
  • Cloudflare Workers for stateless offerings
  • Skillfoundry-owned public routes for the canonical runtime surface

That keeps the runtime independent from any single marketplace while preserving a simple path to distribution through registries and marketplaces later.

Current Layout

signals into ranked bottlenecks and builder-ready opportunity briefs.

  • mechanisms/bottleneck-radar/: internal MCP mechanism for turning noisy source

readiness and drafting marketplace launch packages.

  • products/launchpad-lint/: first external MCP product candidate for auditing launch

probes or offerings.

  • templates/remote-skill-ts/: default starter for new remote TypeScript MCP

Working Rule

Do not treat a mechanism as an offering by default.

A mechanism graduates into an offering only when Skillfoundry has made an explicit decision that:

  • the user-facing utility is clear,
  • the deployment surface is chosen,
  • the pricing or monetization path is chosen,
  • and the artifact deserves its own external lifecycle.

TypeScript Workspace Setup

The repo now includes a pnpm workspace for future TypeScript skills. If pnpm is not installed globally, use corepack:

corepack pnpm install

Preflight: common questions

Is Preflight MCP server safe?
Mostly: it is graded B (81/100). Read the Preflight safety report
How do I install Preflight?
It runs remotely at skillfoundry.synaplex.ai. Add it to Claude Code, Cursor, VS Code or Claude Desktop with the snippets above, or call it through the mcp.market gateway without installing anything.
Does Preflight need an API key?
Not as far as the registry entry and our scan can tell: no credentials are declared or required.
Is Preflight maintained?
The last commit was 60 days ago (2026-09-05). The latest release is v0.1.1.
Is Preflight up?
100% of our last 28 checks got an answer. We check remote servers about four times a day.
What can I use instead of Preflight?
Servers from other publishers that do the same job: MCP Registry Server MCP server.
How does Preflight compare with other MCP servers?
safety score 81/100 (higher than 62% of 48,255 servers); tools 1 (the typical server has 7); tools that change things 100% (typical: 0%. Fewer write tools means less an agent can break). Full comparison.
