🛰️ The Case for

.well-known/mcp.llmfeed.json

Why

.well-known/

?

.well-known/

In a World of LLMs

LLM-based agents need to know:

✅ What this site offers
✅ How to interact
✅ What can be trusted
✅ Who certifies what

Why

.well-known/mcp.llmfeed.json

?

Placing MCP here provides:

✅ Discoverability → any agent can look in a known place
✅ Non-intrusive → no impact on frontend routing
✅ Cross-domain friendly
✅ Open standards compliant
✅ Neutral and decentralized → no central registry required

How It Complements HTML

LLMFeed doesn’t replace HTML:

• HTML serves humans

• .llmfeed.json

  serves agents

It supplements it with:

✅ Trust
✅ Structure
✅ Intent

Why Signatures Matter

Unlike

security.txt

robots.txt

✅ Signed → cryptographic proof of authorship
✅ Certified → attested by a third party (ex:

llmca.org

This is critical in the age of:

• LLM-driven search
• Agent-mediated interactions
• AI-first browsers

Agents need to verify — not just read.

Example Scenarios

AI-First Browser

On visiting:

https://example.com/.well-known/mcp.llmfeed.json

The browser can immediately:

✅ Detect site capabilities
✅ Verify trust level
✅ Surface certified actions to the user
✅ Adapt its interaction model accordingly

LLM-Based Assistant

When a user mentions:

“Check flights on example.com”

The assistant can:

✅ Retrieve

.well-known/mcp.llmfeed.json

Why It Fits MCP Philosophy

.well-known/mcp.llmfeed.json

✅ Declarative → what can be done
✅ Trustable → signed
✅ LLM-friendly → readable and auditable by LLMs
✅ Composable → can point to other feeds (index, exports, prompts...)
