MCP TypeScript SDK release tags are a cadence signal
The modelcontextprotocol/typescript-sdk releases page is the canonical tag list for the TypeScript MCP implementation. Paid MCP is not specified by the SDK; payment rails must attach.
ObservedSourceMCP TypeScript SDK becomes the default client and server kit
The modelcontextprotocol/typescript-sdk repository is the maintained TypeScript implementation of MCP clients and servers. Release tags are TIER_B maintainer evidence of protocol evolution. Paid MCP is not specified by the core SDK; it is an overlay that payment rails must attach.
ObservedSourceVisa Intelligent Commerce opens the card network to AI agents
On 30 April 2025 Visa announced Intelligent Commerce at its Global Product Drop. The program exposes APIs so an authenticated agent can use a tokenized Visa credential under user-set controls. Named collaborators included Anthropic, OpenAI, Stripe and others. This is delegated card-rail commerce, not a stablecoin HTTP 402 protocol.
VerifiedSourceMCP server directories become an agent discovery surface
After MCP’s launch, multiple public directories listed community servers. These catalogs are discovery layers, not payment layers. They create the same PAYABLE ≠ DISCOVERABLE split Foundry already measures on x402.
ObservedSourceAnthropic open-sources the Model Context Protocol
On 25 November 2024 Anthropic published MCP as an open protocol with SDKs and reference servers. The stated aim was to replace one-off tool integrations with a shared client-server contract. That contract later became the substrate for paid MCP and agent tool marketplaces.
VerifiedSourcemodelcontextprotocol.io is the public MCP spec home
The public MCP documentation site is the protocol’s human/machine getting-started surface. It describes hosts, clients, servers, tools, resources and prompts. It does not specify settlement.
ObservedSourceAnthropic releases computer use so Claude can operate a desktop
On 22 October 2024 Anthropic put computer use in public beta on Claude 3.5 Sonnet. Developers can direct the model to look at a screen, move a cursor, click and type. Anthropic described the skill as experimental and error-prone. It is not a payment protocol, but it is a precondition for agents that can complete existing human workflows without a dedicated API.
