What is FallMarket?
FallMarket is the sovereign registry of AI tools, agents, SDKs, MCP servers, and HTTP APIs. It lists 1224 offerings as of July 2026, making it the largest agent-callable estate on GitHub. Every listing is MIT-licensed, Ed25519-signed, and benchmarkable.
Is FallMarket free to use?
Yes. All 1211 listings default to a free tier and every listing ships with MIT source. Paid tiers arrive in Phase 2 alongside $KONO pricing, GBP onramp via Stripe, and escrowed hire flows.
What is an MCP server?
An MCP (Model Context Protocol) server exposes tools to LLMs like Claude, Cursor, or Codex over stdio. It lets an AI client discover and call arbitrary capabilities without a hardcoded integration. FallMarket lists 206 MCP servers, all with copy-to-clipboard install commands.
How do I install an MCP server from FallMarket?
On any listing detail page, click Copy MCP and paste into your terminal. A typical command looks like:
claude mcp add fallhr -- npx -y @ai-native-solutions/fallhr-mcpThe MCP will appear in your Claude, Cursor, or Codex client's tool list within seconds.
Who runs FallMarket?
AI-Native Solutions is the founding publisher of FallMarket. Contact via ai-nativesolutions.com or open an issue at github.com/sjgant80-hub/fallmarket/issues.
Is FallMarket affiliated with Anthropic, OpenAI, Google, or another AI lab?
No. FallMarket is independent, sovereign, and MIT-licensed. It hosts MCPs that work with Claude, Cursor, and Codex, but has no institutional relationship with any AI lab.
How do I list my own tool on FallMarket?
Publish your tool as a public GitHub repo under the sjgant80-hub organization with a package.json, a README, and either an SDK, MCP, or API surface. The nightly refresh job auto-imports it into listings.json. Open-catalog listing (any GitHub org) ships in Phase 3.
What does sovereign mean in this context?
A sovereign tool runs on your machine, ships with its source, and does not lock you into a vendor. Single-file HTML tools open from file:// and work offline. MCP servers run under any client. APIs ship with Dockerfile. SDKs are pure ESM on npm with zero non-essential dependencies.
What is Ed25519 signing?
Ed25519 is an elliptic-curve signature scheme. Every FallMarket listing, benchmark, and transaction is signed with an Ed25519 keypair. The public key doubles as the seller or buyer DID (did:key format). This makes provenance and authorship cryptographically verifiable.
What is $KONO?
$KONO is the mesh-native contribution currency. Phase 2 of FallMarket introduces $KONO pricing on listings alongside a GBP shadow price via Stripe. Buyers can pay in either. Royalties propagate up the fork tree automatically via the fork lineage.
How does the benchmark verification work?
In Phase 3, a Cloudflare Worker runs standard benchmark suites against every listing in a sandboxed environment and signs the results. Buyers can also upload their own test case — the runner tests the product against it and only completes the transaction on pass. This is the empirical trust layer that makes the marketplace agent-native.
What are the four listing kinds?
- SDK — a library on npm, scope
@ai-native-solutions/*. Import in Node or the browser. - MCP — a Model Context Protocol server. Adds to Claude, Cursor, or Codex.
- API — an HTTP endpoint with Dockerfile and docker-compose. Self-host anywhere.
- tool — a standalone single-file HTML tool. Opens from
file://. Zero dependencies.
How often does the catalog update?
The manifest builder runs nightly at 04:00 UTC via GitHub Actions. New tools published to the sjgant80-hub organization appear on FallMarket the next morning.
