Mem0 Memory

Mem0 Memory Management

Persist and retrieve semantic memories across Claude sessions.

Memory Scopes

Organize memories by scope for efficient retrieval:

Core Operations

Adding Memories

# mcp__mem0__add_memory
await mcp.mem0.add_memory(
    content="Decided to use FastAPI over Flask for async support",
    metadata={
        "scope": "project-decisions",
        "category": "backend",
        "date": "2026-01-12"
    }
)

Best practices for adding:

• Be specific and actionable
• Include rationale ("because...")
• Add scope and category metadata
• Timestamp important decisions

Searching Memories

# mcp__mem0__search_memories
results = await mcp.mem0.search_memories(
    query="authentication approach",
    limit=5
)

Search tips:

• Use natural language queries
• Search by topic, not exact phrases
• Combine with scope filters when available

Listing Memories

# mcp__mem0__get_memories
all_memories = await mcp.mem0.get_memories(
    user_id="project-skillforge",
    limit=100
)

Deleting Memories

# mcp__mem0__delete_memory
await mcp.mem0.delete_memory(memory_id="mem_abc123")

When to delete:

• Outdated decisions that were reversed
• Incorrect information
• Duplicate or redundant entries

What to Remember

Good candidates:

• Architecture decisions with rationale
• API contracts and interfaces
• Naming conventions adopted
• Technical debt acknowledged
• Blockers and their resolutions
• User preferences and style

Avoid storing:

• Temporary debugging context
• Large code blocks (use Git)
• Secrets or credentials
• Highly volatile information

Memory Patterns

Decision Memory

"Decision: Use cursor-based pagination for all list endpoints.
Rationale: Better performance for large datasets, consistent UX.
Date: 2026-01-12. Scope: API design."

Pattern Memory

"Pattern: All React components export default function.
Convention: Use named exports only for utilities.
Applies to: frontend/src/components/**"

Continuity Memory

"Session handoff: Completed hybrid search implementation.
Next steps: Add metadata boosting, write integration tests.
PR #456 ready for review. Blocked on: DB migration approval."

Integration with SkillForge

Use memories to maintain context across plugin sessions:

# At session start - recall project context
memories = await mcp.mem0.search_memories(
    query="current sprint priorities"
)

# During work - persist decisions
await mcp.mem0.add_memory(
    content=f"Implemented {feature} using {approach} because {reason}",
    metadata={"scope": "project-decisions"}
)

# At session end - save continuity
await mcp.mem0.add_memory(
    content=f"Session end: {summary}. Next: {next_steps}",
    metadata={"scope": "project-continuity"}
)

MCP Requirements

This skill requires the Mem0 MCP server configured in Claude Desktop:

{
  "mcpServers": {
    "mem0": {
      "command": "npx",
      "args": ["-y", "@mem0/mcp-server"],
      "env": {
        "MEM0_API_KEY": "your-api-key"
      }
    }
  }
}
