# MCP in Claude Code
SUMMARY: Use Synapse tools from the Claude Code terminal agent — persistent memory for coding sessions.

KEY CONTEXT:
Claude Code config: ~/.claude/config.json (or via `claude mcp add` command)
Command: npx -y synapse-mcp-api@latest
Env: SYNAPSE_MIND_KEY (required), SYNAPSE_URL (optional)
Alternative: `claude mcp add synapse -- npx -y synapse-mcp-api@latest`
Then: set SYNAPSE_MIND_KEY env var in your shell
Test: in claude code, type "recall all my memories"

MCP in Claude Code
Claude Code is Anthropic's terminal-based coding agent. With Synapse MCP,
Claude Code gains persistent memory across coding sessions — it remembers
your project context, past decisions, and codebase patterns.
Setup
Method 1: CLI Command (recommended)
[CODE BLOCK]
Method 2: Edit Config File

Verify It Works
Start Claude Code:
[CODE BLOCK]
In the Claude Code prompt, type:
[CODE BLOCK]
Claude should call  and respond with your stored memories.
Common Patterns
Project context persistence
At the start of a coding session:
[CODE BLOCK]
Claude calls , sees your project list, and continues work
where you left off.
Codebase decisions
When you make an architectural decision:
[CODE BLOCK]
Claude calls  with category , priority .
Avoiding past mistakes
[CODE BLOCK]
Claude searches memories with category  and reminds you of past errors.
Task tracking
[CODE BLOCK]
Claude calls , and the task persists across sessions.
