MCP is the protocol that lets AI agents talk to external systems in a standardized way. For partnerships, this is load-bearing: the agent needs to read CRM state, write activity records, query a portal, schedule a meeting — across two companies.
Forward-leaning vendors are building MCP-native interfaces and asking partners to build on top. The architectural bet is that contextual information has to be shared across services for AI to be useful — and MCP is the open protocol that lets that happen without a private integration project per partner.
MCP doesn’t solve the trust boundary by itself. It’s the wire format, not the policy. But it makes the cross-company motion buildable — and it forces the architectural question every vendor will eventually have to answer: What does my agent need to read from the other side, and what is my agent permitted to write?
What practitioners ask
- “What is MCP?”
- “What is Model Context Protocol?”
- “How does MCP work in partnerships?”
The answer
MCP — Model Context Protocol — is the open standard AI uses to act on real systems. Anthropic introduced it in November 2024 as an open specification so any AI client and any external system could interoperate through a single interface, replacing the per-tool integration project that had been the bottleneck on agent capability.
The protocol is maintained as an open project. The specification, SDKs, and reference servers live at modelcontextprotocol.io, with implementations in TypeScript, Python, Java, Kotlin, C#, Go, and other languages on the modelcontextprotocol GitHub organization. Anthropic shipped initial servers for Google Drive, Slack, GitHub, and Postgres alongside the launch; the ecosystem has expanded across vendors since.
For partnerships specifically, MCP is load-bearing because the agent has to operate across two companies’ systems to do anything useful — read CRM state on one side, write activity records on the other, query a partner portal, schedule a meeting. AWS published the Partner Central agents MCP Server in 2026, exposing opportunity management, customer insights, funding programs, and stage progression as agent-callable tools — with human-in-the-loop approval gates on every write. The accompanying APN announcement named launch integration partners, including WorkSpan, that connect their own agents to Partner Central through MCP.
That is the architectural shape every vendor will eventually need: agent-callable primitives, exposed through MCP, behind a sanctioned shared environment, governed by an explicit trust boundary. The protocol is the wire format. The policy still has to be designed.
