MCP Server Free Tools Personas

Why mcp-crew?

Agent Fleets are expensive. Every agent needs its own LLM API call. mcp-crew takes a different approach:

Zero extra API cost — Runs within your existing Claude subscription
Memory-integrated personas — Each persona auto-loads your business context via Nex Memory
Battle-tested prompts — Extracted from 20+ production agents with domain-specific frameworks
Works everywhere — Claude Desktop, Claude Code, Cursor, VS Code, any MCP client

10 Tools

Tool	Description
`crew_guide`	Help and onboarding (5 topics)
`crew_list`	List personas by category
`crew_activate`	Activate a persona with optional business context
`crew_deactivate`	Return to default Claude
`crew_status`	Show active persona + duration

3 Workflows

Workflows chain multiple personas for complex tasks:

Strategy Review — CEO analyzes → CFO evaluates financials → CTO checks feasibility
Content Pipeline — CMO drafts → Analyst fact-checks → Creative polishes
Product Launch — Analyst researches → PM writes PRD → CEO decides → CMO plans marketing → CTO reviews tech

Each workflow step uses the full persona prompt with all frameworks and decision models.

Memory Bridge

When connected with StudioMeyer Memory, personas auto-load your business context:

CFO knows your last pricing decisions and revenue numbers
CEO knows your strategy and open goals
Analyst knows your competitor research
PM knows your feature backlog and user feedback

Custom Personas

Create your own personas via tool or file:

crew_create(
  name: "legal",
  displayName: "Legal Advisor",
  prompt: "You are a Legal Advisor focused on GDPR, contracts...",
  tags: ["legal", "compliance"],
  memory_queries: ["legal", "contracts"]
)

Custom personas are saved to ~/.mcp-crew/personas/ and loaded instantly.

How It Works

mcp-crew delivers detailed system prompts via MCP. When you activate a persona:

The persona's full prompt is loaded (role, frameworks, anti-patterns, examples)
Memory queries are injected (if Nex Memory is connected)
Business context is appended (if provided)
Claude adopts the role with full tool access to your other MCP servers

No extra LLM calls. No API keys. Just better prompts.
