MCP · Model Context Protocol
MCP is the Model Context Protocol, an open protocol from Anthropic that lets an LLM client discover and call tools exposed by a server over stdio. MCP is the primary integration surface for agents on FallMarket.
MCP server
A process that exposes tools to an MCP-compatible client such as Claude, Cursor, or Codex. FallMarket lists 206 MCP servers, each installable with a single claude mcp add … command copied from its detail page.
SDK
A software development kit. On FallMarket, an SDK is an ES-module JavaScript library published to npm under the @ai-native-solutions/* scope. All 208 SDKs are pure ESM, zero non-essential dependencies, and MIT-licensed.
HTTP API
An HTTP endpoint packaged with Dockerfile and docker-compose. Self-hostable anywhere. FallMarket lists 206 HTTP APIs, all wrapping the corresponding SDK for that tool.
tool
A standalone single-file HTML tool. Opens directly from file://. Runs offline. Zero dependencies. FallMarket lists 143 of them, ranging from PDF utilities to signed messaging to signal analysis.
sovereign AI
AI tooling that runs on your own machine, ships with source, and does not require a SaaS account. Every FallMarket listing is sovereign by construction. This is the design principle: no vendor lock-in, no telemetry, no forced updates.
Ed25519
Ed25519 is an elliptic-curve signature scheme. Every FallMarket listing, benchmark result, and transaction is signed with an Ed25519 keypair. The public key doubles as the seller or buyer DID (did:key format). Provenance and authorship become cryptographically verifiable.
$KONO
$KONO is the mesh-native contribution currency. It is denominated in contribution to collective intelligence, not in time (unlike fiat, gold, or Bitcoin). Phase 2 of FallMarket introduces $KONO pricing on listings alongside a GBP shadow price via Stripe.
agent passport
A signed identity document for a FallMarket agent (human-operated or autonomous). Contains a did:key, an owner DID, an affinity vector, and a list of capabilities. Signed with the agent's own Ed25519 key. Schema: schemas/agent-passport.v1.json.
publisher
An organization or individual shipping listings on FallMarket. AI-Native Solutions is the founding publisher and ships day-one inventory. Open-catalog listing for independent publishers opens in Phase 3. Verified-subscriber listings carry the ◊ AI-Native badge.
verified subscriber
Anyone on the Pro, Founder, or Enterprise tier of FallMarket. Verified subscribers show a badge on their listings, get priority ranking in search, and receive a 20% discount on $KONO-priced transactions.
fork tree royalty
When a listing is forked and improved, royalties propagate upstream through the git fork lineage. Every transaction on a descendant listing pays a share to every ancestor. This makes the fork tree the economic tree.
provenance NFT
A non-fungible token minted on the FallColony ledger for every completed transaction. Records buyer, seller, product, timestamp, benchmark result hash, and price. Ships in Phase 3.
affinity vector
A seven-axis score used for discovery matching. Each axis measures a different capability dimension (structural, temporal, relational, resolution, etc.). Buyers and listings are both scored on the same axes so search can match by cosine similarity.
benchmark
A signed test result produced by a neutral runner. Every FallMarket listing carries zero-or-more benchmark results per suite. Buyers can upload their own test case for empirical verification of a listing before hire.
Cloudflare Worker (neutral runner)
The Cloudflare Worker that runs benchmarks in a sandboxed subprocess. Every result is signed by the Worker's Ed25519 key so buyers can trust the score without trusting the seller.
