❓ Frequently Asked Questions — MCP & LLMFeed


What is MCP in one sentence?

It’s an open protocol that lets LLM-based agents understand what a site offers, how to interact, and what trust level to assign — through structured, signed, declarative feeds.


What is LLMFeed?

It’s the canonical JSON format used by MCP.
The .llmfeed.json structure is:

✅ Simple and human-readable
✅ Designed to be LLM-friendly
✅ Composable and extensible
✅ Trust-aware (signed, certifiable)
✅ Declarative, not imperative


Why .well-known and not a plugin / SDK / proprietary API?

Because .well-known makes MCP:

Discoverable
Decentralized
Composable
Independently auditable
Compatible with Web philosophy

LLMFeed is intentionally lighter than SDK-heavy designs — it favors progressive enhancement of the Web.


What is the “Agentic Web” and how does MCP fit?

The Agentic Web is an emerging vision where LLM-based agents are first-class citizens of the Web:
→ not just consumers of HTML, but actors with intent, trust boundaries, and interaction models.

MCP provides the contextual layer these agents need to operate safely and transparently.


How is trust handled?

✅ Every .llmfeed.json can be signed
✅ Feeds can be certified by a third party (ex: llmca.org)
Signed blocks are verifiable by agents
✅ Certification attests intent + trust scope

Agents can reason about:

  • What is signed
  • Who certified it
  • What trust level to assign

What is ExportToLLM and why does it matter?

It’s a simple pattern: turn any content into an agent-readable capsule — signed, trusted, structured.
It enables:

Agent-to-agent workflows
Portable context for users
Progressive enhancement of any site, even without full MCP adoption

It’s one of the most immediately impactful ways to make a site "agent-ready".


How is this different from Schema.org?

Schema.org describes what’s on a page.
MCP and .llmfeed.json declare:

What agents can DO
What is trusted
How to interact
Fallbacks
Agent guidance

It’s a layer for intent and trust, not just metadata.


Does this replace HTML?

No. It complements HTML:

✅ HTML → for human users
✅ MCP → for LLM-based agents

They can co-exist and evolve together.


How does this help LLM-based agents?

It gives agents:

Trust signals
Declared capabilities
Clear intent routers
Portable prompts
Certified action scopes
Session context replay possibilities

This enables safer, more predictable interactions.


How does this help site owners?

✅ Declare what’s allowed / trusted
✅ Attract agent-based integrations
✅ Improve agent UX
✅ Reduce scraping and misinterpretation
✅ Align with upcoming regulations (AI transparency, data provenance)


I’m building an AI-first browser / platform. Why should I support MCP?

MCP provides:

✅ A declarative contract for agents
Trust signals for UX decisions
✅ A progressive layer for the Web → no lock-in
Portable UX patterns like ExportToLLM

Supporting MCP helps:

Guide agent behavior
Respect user and site intent
✅ Enable a safer, more predictable Agentic Web.


How does this scale?

✅ MCP feeds are modular
✅ Agents can prioritize by trust level
✅ Signed and certified feeds are cacheable
✅ Progressive enhancement means no mandatory full adoption — sites can implement incrementally.


How does this compare to pure plugin / API models?

✅ MCP is decentralized
✅ No central registry required
✅ No mandatory SDKs
✅ Works with any agent that understands MCP / .llmfeed.json
✅ Aligns with Web architecture (URL-first, file-based, declarative)


Is this compatible with W3C philosophy?

Yes — .well-known is a standard pattern.
MCP:

✅ Respects existing Web standards
✅ Is open, auditable
✅ Encourages progressive adoption
✅ Avoids lock-in


Is MCP open and community-driven?

Yes:

✅ Spec is open
✅ No lock-in
✅ Community-driven extensions possible
llmca.org provides neutral certification


What’s next?

  • More standard feed types
  • Reference agent implementations
  • Browser extension prototypes
  • Certification process refinement
  • Ecosystem growing around MCP

✅ Propose new feed types
✅ Build tools (parsers, extensions, agents)
✅ Help with industry advocacy
✅ Participate in certification working groups
✅ Implement MCP in AI-first browsers and apps
