PART I: THE PROBLEM 02 / 09

The Context Silo

Agents are smart but forgetful. Working across multiple projects (Context A -> Context B) meant manually copying context. There was no "Clipboard Manager" for AI memory.

The "Daisy Chain" Problem

You find an insight in a PDF report (Agent A) but want to apply it to your code (Agent B). Moving this insight is manual friction.

Ephemeral Memory

Agents have no persistence. Once you close the session, the knowledge is gone.

PART II: THE SOLUTION 03 / 09

MCP for Power Users

Elevator Pitch:
A Model Context Protocol (MCP) tool allowing agents to Read/Write/Zip/Search and "Teleport" context between sessions via a persistent SQLite memory.

Capability	Traditional Context	FileOps (MCP)
Persistence	Session only.	SQLite Backed Meta-Memory
Cross-Project	Impossible.	"Quick Save" / "Quick Load"

Core Verbs

`learn(meta)`: Save insight to DB.
`remember(query)`: Vector search DB.
`teleport(ctx)`: Move context between agents.

PART III: TECHNOLOGY 04 / 09

Architecture

A Node.js server exposing JSON-RPC endpoints to the Agent.

Interface: MCP (Model Context Protocol).
Storage: Local SQLite for file metadata & memory.
Action: NodeJS `fs` module for actual file ops.

// The "Teleport" Logic
/* 
User: "FileOps, save this TSLA report comparison."
Agent -> FileOps.save("tsla_report_q3", content);

... switch to Cursor IDE ...

User: "FileOps, load the TSLA report."
Agent -> FileOps.load("tsla_report_q3");
> Returns structured summary from SQLite
*/

PART IV: EVOLUTION 05 / 09

The MCP Era

Standardization

"FileOps was a precursor to the Model Context Protocol (MCP). What I hackily built in Node.js is now a standardized JSON-RPC spec supported by Anthropic and others, validating the need for 'Tool Use' as a first-class citizen."
