GenAI PMMCP
An interoperability protocol for connecting AI systems and tools. Here it is described through a public roadmap covering long-running workloads, local-server HTTP, discovery, identities, permissions, and generated SDKs.
Key Highlights
- MCP is an interoperability protocol that standardizes how AI systems connect to tools, services, and context sources.
- Recent momentum includes a public roadmap focused on long-running workloads, discovery, delegated permissions, and generated SDKs.
- For AI PMs, MCP is most relevant as a reusable integration layer that can reduce custom connector work across products.
- Enterprise adoption depends heavily on permissioning, identity, trust, and operational reliability rather than just basic tool calling.
- Real-world examples like HubSpot and Claude ecosystem integrations show MCP moving from experimentation toward production usage.
MCP
Overview
MCP, short for Model Context Protocol, is an interoperability protocol for connecting AI systems to external tools, data sources, and software environments in a standardized way. In practice, it gives models and agents a common interface for discovering capabilities, invoking tools, accessing context, and coordinating with services such as CRMs, developer platforms, calendars, communication apps, and custom backends. For AI product teams, MCP represents a shift from bespoke one-off integrations toward a more reusable connector layer across agents, apps, and enterprise systems.For AI Product Managers, MCP matters because it affects product architecture, ecosystem strategy, and user experience. As more products expose MCP servers, connectors, and tool surfaces, PMs can design AI features that plug into a broader ecosystem rather than rebuilding every integration from scratch. Recent discussion has focused on a public roadmap for MCP covering long-running workloads, local-server HTTP support, progressive discovery, identity and delegated permissions, and generated SDKs—signals that the protocol is maturing from experimentation toward production-grade use.
Key Developments
- 2026-05-20 — PromptLayer outlined MCPs and APIs as two core protocol layers powering AI workflows, distinguishing MCP’s role in agent actions, data lookups, prompt evaluation, and orchestration patterns in production systems.
- 2026-05-22 — Qwen introduced Qwen3.7-Max with multi-agent MCP productivity integrations, highlighting MCP’s role in agent-first toolchains and long-running autonomous workflows.
- 2026-05-26 — PromptLayer further examined MCP vs API architecture patterns, reinforcing the idea that MCP complements rather than replaces APIs in modern AI systems.
- 2026-06-04 — Anthropic’s Claude Partner Hub was described as connecting through an MCP connector for in-Claude queries and actions, showing MCP’s use as an enterprise integration layer inside partner ecosystems.
- 2026-06-10 — An analytics tool praised by Santiago emphasized deployability “everywhere via MCP,” illustrating how vendors position MCP as a standard access layer for AI-enabled products.
- 2026-08-15 — Santiago referenced a library capable of mocking LLMs, MCP tools, agents, and databases, suggesting growing developer infrastructure for testing MCP-based systems without relying on live services.
- 2026-08-17 — Deepagents, built on LangGraph, was described as supporting standard endpoints including MCP and a2a, indicating MCP’s role alongside other agent interoperability standards.
- 2026-08-22 — HubSpot’s remote MCP server at mcp.hubspot.com was used through an MCP Auth App to list, create, and update CRM contacts, providing a concrete example of remote MCP for business data operations.
- 2026-08-24 — Guillermo Rauch said fx’s extension philosophy centers on open protocols including MCP, Skills, and Plugins, framing MCP as part of a composable AI software stack.
- 2026-08-25 — Philipp Schmid shared an MCP public roadmap for the next 6–12 months, covering long-running workloads, HTTP for local servers over stdio, progressive discovery, standard identities and delegated agent permissions, and specification-checked generated SDKs.
Relevance to AI PMs
- Design integrations as reusable product infrastructure. Instead of treating each tool connection as a bespoke feature, PMs can use MCP as a standard interface layer across products such as GitHub, Notion, Gmail, Google Calendar, Stripe, or internal systems. This reduces duplication and can speed up roadmap execution.
- Plan for auth, permissions, and trust early. The roadmap emphasis on standard identities and delegated permissions is especially important for enterprise AI products. PMs should define which actions agents can perform, what approval steps are needed, and how users understand and audit tool access.
- Prioritize production readiness, not just demos. Features like long-running workloads, generated SDKs, and local-server HTTP support matter for reliability and developer adoption. PMs evaluating MCP should look beyond “tool calling works” and assess latency, discoverability, testing, permissioning, and operational support.

“HubSpot’s remote MCP server at mcp.hubspot.com was connected through an MCP Auth App to list, create, and update CRM contacts, while deletion remained unavailable.”
#5 ▶️ I Tested HubSpot's New MCP Server SyntaxGTM HubSpot’s remote MCP server at mcp.hubspot.com was connected through an MCP Auth App to list, create, and update CRM contacts, while deletion remained unavailable. HubSpot has two MCP servers: the local Developer MCP server for HubSpot CMS and app development, and the remote HubSpot MCP server for CRM data access. The remote MCP added the manage CRM objects tool, enabling creation and updates for CRM objects such as contacts and deals; it supports read, create, and edit operations but not deletion. An MCP Auth App requires an app ID, client ID, and redirect URL; after authorization, Claude used the HubSpot connector’s get contacts / search CRM objects capability to return contacts in roughly 5–6 seconds, including when using Claude Haiku.
