AWS MCP Setup Guide

Detects, selects, and configures AWS MCP servers — full API access or auth-free docs search — with built-in troubleshooting.

Dev & CodingIntermediate★ 365⑂ 40AI score 9/10Last updated: Jun 15, 2026

What it does

  • Checks whether AWS MCP is already wired up via /mcp, claude mcp list, and the .mcp.json / ~/.claude.json config hierarchy.
  • Uses which uvx and aws sts get-caller-identity to pick between the Full AWS MCP Server (API calls + docs) and the AWS Documentation MCP (docs only, no auth).
  • Supplies ready-to-paste mcpServers JSON, three credential strategies (profile, env vars, IAM role), and the minimal IAM policy.
  • Verifies expected tool names after setup and provides a troubleshooting table for uvx: command not found, AccessDenied, and InvalidSignatureException.

Who it's for

  • Developers and DevOps engineers who want Claude Code to search AWS docs and call AWS APIs.
  • Team leads standardizing a shared project-level .mcp.json.
  • Beginners with no Python toolchain who still want AWS documentation lookup.

Examples

  1. "Set up AWS MCP for me" → environment probe, then the matching config block.
  2. "My MCP tools aren't showing up" → walks the local→project→user precedence and restart requirement.
  3. "I'm getting AccessDenied" → returns the IAM policy with the required aws-mcp actions.

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the plugins/aws-common/skills/aws-mcp-setup folder from the GitHub repo zxkane/aws-skills into my ~/.claude/skills/aws-mcp-setup/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/zxkane/aws-skills.git /tmp/aws-skills && mkdir -p ~/.claude/skills && cp -r /tmp/aws-skills/plugins/aws-common/skills/aws-mcp-setup ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repo: git clone https://github.com/zxkane/aws-skills.git /tmp/aws-skills
  3. Create the skills folder: mkdir -p ~/.claude/skills
  4. Copy the skill: cp -r /tmp/aws-skills/plugins/aws-common/skills/aws-mcp-setup ~/.claude/skills/
  5. Restart Claude Code and ask it to "configure AWS MCP".
  6. (Optional) For the full server, install uv with pip install uv and confirm credentials with aws sts get-caller-identity.
