Agentic Workflows and MCP

Definition

Agentic workflows are multi-step AI processes where an LLM takes autonomous actions — reading files, querying tools, writing outputs — to complete a goal. MCP (Model Context Protocol) is an open protocol that standardizes how agents connect to external tools and data sources.

The MCP Protocol

MCP decouples agents from specific tool implementations:

  • Agents speak a common protocol
  • Tool providers (memory systems, databases, APIs) implement MCP servers
  • Any MCP-compatible agent can use any MCP-compatible tool without custom integration code

Supported in: Claude (Anthropic), Cursor, VS Code Copilot, Codex, and others.

The Link project defines a minimal four-step protocol that well-behaved agents should follow when using memory:

  1. Check status — confirm memory is available and up to date
  2. Ingest sources — add new raw material to the knowledge base
  3. Query context — retrieve relevant knowledge before responding
  4. Validate changes — confirm that updates were applied correctly

This pattern generalizes beyond memory: it’s a sound contract for any agent interacting with stateful external systems.
