MCP server AgentCrew

Why AgentCrew?

AgentCrew lets you build a team of specialists, each with the right tools and personality for the job.

• An Architect that weighs trade-offs before a line of code is written.
• A Coder that implements cleanly — no scope creep, no over-engineering.
• A Reviewer that catches what others miss.
• A Researcher that cross-references multiple sources before drawing conclusions.
• A Browser Operator that navigates web apps, fills forms, and clicks through workflows.

Agents hand off work to each other when a task needs a different specialty. You stay in control, orchestrating the team from one interface.

When AgentCrew fits: You have a complex task that benefits from multiple perspectives — building a feature from design to deployment, researching and writing a report, or automating a multi-step workflow.

When a single assistant is enough: You need one focused conversation with no tool access or multi-agent orchestration.

Quick Start

1. Install (10 seconds)

macOS / Linux

curl -LsSf https://agentcrew.dev/install.sh | bash

Windows

powershell -ExecutionPolicy ByPass -c "irm https://agentcrew.dev/install.ps1 | iex"

pip (any platform)

pip install agentcrew-ai

2. Add an API key — or skip this step entirely

Most tools need a paid API key. AgentCrew supports several options that don't require one:

Subscription-based (no API key needed):

# OpenCode Go — curated open-source models (GLM, Kimi, MiMo, Qwen)
agentcrew chat --provider opencode_go

# ChatGPT Plus / Pro (uses Codex models)
agentcrew chatgpt-auth
agentcrew chat --provider openai_codex

# xAI Subscription (supported for eligible accounts)
agentcrew xai-auth
agentcrew chat --provider xai --model-id grok-4.7
# Other curated subscription models
agentcrew chat --provider xai --model-id grok-build-0.1
agentcrew chat --provider xai --model-id grok-4.3
# Local sign-out/reset (does not revoke the remote xAI session)
agentcrew xai-auth --logout

# GitHub Copilot subscribers
agentcrew copilot-auth
agentcrew chat --provider github_copilot

xAI Subscription uses AgentCrew's built-in OAuth device login and the direct xAI Responses API. Availability and model access depend on your current xAI plan and account entitlement. Allowances, overages, and billing are controlled by xAI; a displayed token cost of 0.0 does not mean requests are free. Grok Build 0.1 uses the model's default reasoning because it does not expose selectable reasoning effort through this integration. xai-auth --logout deletes local tokens only; it cannot revoke them remotely.

Pay-as-you-go API keys:

export DEEPINFRA_API_KEY="your-key"       # DeepInfra — open models (LLaMA, Qwen, etc.)
export OPENAI_API_KEY="sk-proj-..."       # OpenAI GPT-4o
export GEMINI_API_KEY="AIza..."           # Google Gemini — free tier available

Or store keys in ~/.AgentCrew/config.json:

{
  "api_keys": {
    "OPENAI_API_KEY": "sk-proj-..."
  }
}

Custom providers:

Custom providers such as Ollama, llama.cpp, and LM Studio are configured in the same ~/.AgentCrew/config.json file. See Custom LLM Providers for the full schema, llama.cpp configuration, model capabilities, and sampling options.

All supported providers:

Provider	Cost profile	Best for
OpenCode Go	Subscription-based	Curated open-source models, no API key
Command Code	Subscription-based	Frontier models via subscription
DeepInfra	Pay-as-you-go, low cost	Open models (LLaMA, Qwen, etc.)
Together AI	Pay-as-you-go	Open models, fine-tuning

GitHub Copilot	Included with subscription	Coding-focused, no extra cost
ChatGPT Codex	Included with Plus/Pro sub	No extra cost for subscribers
xAI Subscription	Included with eligible plan	Grok models through OAuth device login
Custom	Free (local)	Fully offline (Ollama, llama.cpp...)

Which provider should I pick?

If you...	Pick this
Want curated open-source models	OpenCode Go — subscription-based
Want low-cost, open-source friendly	DeepInfra
Have a Command Code subscription	Command Code
Have ChatGPT Plus / Pro	openai_codex — no extra cost
Have GitHub Copilot	github_copilot — no extra cost
Have an eligible xAI subscription	xai — OAuth device login
Want a free tier to start	Google Gemini
Need fully offline / air-gapped	Custom (Ollama, llama.cpp, etc.)

3. Launch

# Desktop GUI (default)
agentcrew chat

# Terminal mode — great for SSH, tmux, low-resource environments
agentcrew chat --console

On the first launch, AgentCrew walks you through creating your first agent.

4. Create your first agent

agentcrew create-agent

Or define one manually in ~/.AgentCrew/agents.toml:

[[agents]]
name = "CodeAssistant"
description = "Helps write and review code"
tools = ["code_analysis", "file_editing", "web_search", "memory"]
system_prompt = """You are an expert software engineer.
Focus on code quality, security, and maintainability.
Today is {current_date}."""

Use Cursor Agent

Cursor Agent is a supported AgentCrew agent type for repository editing and coding tasks. The standard AgentCrew installation includes the Cursor SDK; the Cursor IDE and CLI are not required. Set your Cursor API key, then add a [[cursor_agents]] entry:

export CURSOR_API_KEY="your-cursor-api-key"

[[cursor_agents]]
name = "CursorCoder"
description = "Edits the current repository with Cursor Agent."
model_id = "composer-2.5"
cwd = "."
tools = ["memory"]

Files stay on your machine while inference is hosted by Cursor. Start AgentCrew and select the agent with /agent CursorCoder. See Cursor Agent configuration for all fields and model-selection options.

5. Start working

> /agent Architect
> Design a clean API for a task manager.
>
> @Coding  Implement the task manager in Python using FastAPI.
>
> @Reviewer  Review the code for security issues.

The @AgentName syntax hands off a subtask to another agent. The receiving agent picks up with full context and its own specialized tools and instructions.

What's in the box?

Four ways to use AgentCrew

Mode	Command	Best for
Desktop GUI	agentcrew chat	Daily work, drag-and-drop files, visual diffs
Terminal	agentcrew chat --console	Remote servers, keyboard-first workflows
One-shot jobs	agentcrew job --agent "Name" "task" ./files	CI/CD, batch processing, automation
HTTP API	agentcrew a2a-server	Integrate with other apps, multi-instance agent networks

Job mode example:

agentcrew job --agent "CodeAssistant" \
  "Review for security issues" \
  ./src/**/*.py

A2A server example:

agentcrew a2a-server --host 0.0.0.0 --port 41241

Tools — enable only what each agent needs

Tool	What it does	When to enable it
code_analysis	Read files, grep, analyze repo structure	Any agent working with code
file_editing	Write/modify files (search-replace blocks, backups)	Coding and documentation agents
web_search	Search the web via Tavily	Research and fact-checking agents
fetch_webpage	Extract content from a URL	Research agents
browser	Full browser automation (navigate, click, form fill)	QA, web scraping, form-filling agents
command_execution	Run shell commands (rate limits, audit logs)	DevOps, code execution agents
memory	Store and retrieve conversation context	Almost every agent

adaptive_learning	Learn behavioral patterns from interactions	Agents that should adapt over time
voice	Speak and listen (ElevenLabs or DeepInfra)	Voice-interactive agents
MCP tools	External tools via Model Context Protocol	Any agent needing external integrations
transfer	Hand off tasks to other agents	Automatically available in multi-agent setups

Communication protocols

AgentCrew speaks three protocols:

• Console / GUI — Human-to-agent: the chat interface you use daily.
• A2A (Agent-to-Agent) — HTTP+JSON-RPC protocol. Connect multiple AgentCrew instances so one can delegate to agents on another machine.
• ACP (Agent Communication Protocol) — WebSocket protocol for custom clients, IDE integrations, and headless agent control.

Real-world workflows

🧑‍💻 Feature development — from idea to PR

You: @Architect  Design the data model for a multi-tenant SaaS app
     @Coding     Implement it with SQLAlchemy
     @Reviewer   Review the code for security issues

Three agents, one conversation. The Architect thinks about trade-offs, the Coder implements cleanly, the Reviewer catches blind spots.

📊 Financial report generation

# Five specialized agents, each focused on one step
[[agents]]  name = "FinancialDataExtractor"   # parse raw statements
[[agents]]  name = "RatioAnalyst"             # compute key ratios
[[agents]]  name = "TrendAnalyst"             # spot patterns over time
[[agents]]  name = "RiskAssessor"             # flag red flags
[[agents]]  name = "ReportingSynthesizer"     # compile into final report

Each agent handles one step of the pipeline. The Synthesizer collects all findings and writes the final report. See examples/agents/agents-financial-report.toml.

🌐 Multi-instance agent network

# Server A — hosts research agents
server-a$ agentcrew a2a-server --port 41241
