pūrmemo MCP Server

Claude knows who you are before you say a word.

pūrmemo gives your AI a persistent memory and identity layer — your role, expertise, active projects, and conversation history — available instantly in every session, across every platform.

What It Does

• Remembers everything — save conversations, decisions, and context; search them later with natural language
• Knows who you are — your role, expertise, tools, and active projects load automatically at session start
• Works everywhere — Claude Code, Claude Desktop, Cursor, Windsurf, Zed, and any MCP-compatible platform

3. Start Using

You: "What's the project status?"
Claude: Based on your identity and recent memories:
  You're a founder working on a B2B SaaS product.
  Recent work: pūrmemo (15 sessions), auth refactor (3 sessions)
  Last session: "Fixed JWT refresh token rotation"

What You Get

Resources (attach to any conversation via the + button)

Example — attach memory://me at session start:

You are working with:
**Chris** — Founder, B2B SaaS
Expertise: product, fullstack, ai
Tools: cursor, claude, supabase
Style: systems thinker

Recent work:
- pūrmemo (15 recent sessions)
- auth-refactor (4 recent sessions)

Working on: MCP Resources + Prompts feature

No re-explaining who you are. No repeating your stack. Just continue.

Prompts (conversation starters in the + menu)

Tools

Core

Workflows

Community

get_user_context in action:

You: "What have I been working on?"
Claude: [calls get_user_context]

Your profile: Founder · B2B SaaS · fullstack/ai/product
Active projects:
  • pūrmemo — "MCP server resources and prompts" (15 sessions)
  • auth-refactor — "JWT refresh token fix" (4 sessions)
Working on: MCP Resources + Prompts feature

Identity Layer

pūrmemo maintains a cognitive fingerprint — a persistent profile of who you are that loads automatically into every session.

Set it once at app.purmemo.ai → Settings → Identity:

• Role — founder, engineer, designer, researcher, ...
• Domain — your primary field (B2B SaaS, ML research, design systems, ...)
• Expertise — your key skills (product, fullstack, ai, ...)
• Tools — what you work with (cursor, claude, supabase, ...)
• Work style — how you think (systems thinker, iterative builder, ...)
• Working on — your current focus, updated per session

Once set, every new session inherits this context. Claude already knows your background, your stack, and what you were doing last time — without you having to explain it.

Slash Commands (Claude Code)

After installing the slash commands (see Claude Code setup above):

The /context command is especially useful at the start of a session: it calls get_user_context and surfaces your identity and recent work so Claude already knows where you left off.

Living Document Pattern

Same title = update, not duplicate. Build on memory over time:

You: "Save this as auth-refactor"
Claude: ✅ Saved — "auth-refactor" (new)

[... continue working across multiple sessions ...]

You: "Save as auth-refactor"
Claude: ✅ Updated — "auth-refactor" (3 updates, not 3 copies)

Long conversations? Auto-chunked at 100K+ characters and reassembled on recall.
