Values you fill in
AWS_PROFILEenvNamed profile from ~/.aws/config to use. Leave unset to use the default profile.AWS_REGIONenvDefault AWS region if not set elsewhere.- Static AWS access key. Only needed if not using a profile/SSO/role.
- Static AWS secret key. Only needed if not using a profile/SSO/role.
- Temporary session token, if using short-lived credentials.
AWS_MCP_ALLOW_WRITEenvSet to "true" to permit mutating AWS CLI commands. Defaults to read-only.AWS_MCP_ALLOWED_SERVICESenvOptional comma-separated allowlist of AWS CLI service names (e.g. "s3,ec2"). Unset allows all.AWS_MCP_CLI_PATHenvOptional path to the aws binary. Defaults to "aws" resolved via PATH.
These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions
Is AWS MCP Connector safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
You need to fill in: AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.1.2) reached the registry 3 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need MCPB on your computer.
What can I use instead?
In the same category: GitHub, Desktop Commander, Cloudflare MCP

🔌 aws-mcp-connector
Talk to AWS CLI from an MCP-speaking agent.
A single static Go binary that speaks the Model Context Protocol and lets an agent run AWS CLI commands: any aws invocation, across every service the CLI supports, with a read-only-by-default safety gate on anything that mutates state.
No Python, no uv, no runtime dependency to install — just a binary and an .mcp.json. It shells out to the aws binary already installed and configured on the host (profile, SSO, IAM role, or static keys — whatever the AWS CLI's own credential chain resolves) instead of reimplementing the AWS SDK, so it gets the full breadth of the CLI for free rather than a hand-curated subset of services.
✨ Why this exists
An agent that only has a narrow, hand-picked set of AWS tools hits a wall
the moment you need something outside that set. This connector instead
wraps the AWS CLI itself, so an agent can run
aws s3 ls, `aws ec2
describe-instances
,aws iam list-users` — anything the CLI can do —
without waiting on a new tool to be written for it. Mutating commands are
blocked by default and require both a server-level opt-in and a per-call
confirm=true, so exploring/debugging is safe out of the box.
🧰 Tools
| Tool | What it does | Write? |
|---|---|---|
aws_exec | Run any aws ... command. Read-only by default — mutating commands need AWS_MCP_ALLOW_WRITE=true on the server *and* confirm=true on the call. | ✅ (gated) |
aws_help | Show aws [subcommand] help text — always safe, use it to check exact syntax before calling aws_exec. | |
aws_whoami | Show the AWS identity (account, ARN, user/role) the configured credentials resolve to. | |
aws_list_profiles | List named profiles configured in ~/.aws/config on the host. |
Every tool accepts an optional response_format: markdown (default, pretty tables for a chat UI) or json (for programmatic use).
🚀 Quickstart
Fastest path: grab a prebuilt bundle from the latest release — download aws-mcp-connector-plugin- - - .zip, unzip it, and point Cowork/Claude at the plugin/ folder inside (see step 4 of SETUP.md). No Go toolchain required.
From source:
# 1. Buildcd go-server go mod tidy go build -o aws-connector-server . cp aws-connector-server ../plugin/servers/go/
2. Set up auth — needs the aws CLI itself installed and configured
(aws configure / aws sso login) — see SETUP.md
export AWS_PROFILE=default # optional, only if not using "default"
3. Run
./go-server/aws-connector-server # serves MCP over stdio
Or make build — see the Makefile for every shortcut (test, vet, fmt, lint, tidy).
Full walkthrough — including wiring this up as a Claude/Cowork plugin — is in [SETUP.md](SETUP.md).
🔐 Configuration
Everything is environment variables, passed through by the plugin's .mcp.json:
| Variable | Purpose | Default |
|---|---|---|
AWS_PROFILE | Named profile from ~/.aws/config to use. | unset (default profile) |
AWS_REGION | Default region if not set elsewhere. | AWS CLI's own default |
AWS_ACCESS_KEY_ID / AWS_SECRET_ACCESS_KEY / AWS_SESSION_TOKEN | Static credentials — only needed if not using a profile/SSO/role. | unset |
AWS_MCP_ALLOW_WRITE | "true" to permit mutating commands at all (still needs confirm=true per call). | false (read-only) |
AWS_MCP_ALLOWED_SERVICES | Comma-separated allowlist of AWS CLI service names, e.g. "s3,ec2". | unset (unrestricted) |
AWS_MCP_CLI_PATH | Path to the aws binary. | aws resolved via PATH |
🧪 Quality bar
This isn't a toy script — it's got the same checks you'd expect from a production Go service:
- ✅ Unit tests for every input-validation path (
go test ./...) - ✅ `go vet` + `gofmt` clean
- ✅ [golangci-lint](https://golangci-lint.run/) (govet, staticcheck, errcheck, gosec, and more)
- ✅ [govulncheck](https://go.dev/blog/vuln) — no known vulnerabilities in the dependency graph
- ✅ [CodeQL](https://codeql.github.com/) static security analysis on every push
- ✅ End-to-end verified against a real (or sandboxed) AWS CLI backend — not mocks
- ✅ [Dependabot](.github/dependabot.yml) keeps Go modules and Actions current
All of it runs in CI on every push and PR.
🏷️ Releases & versioning
Versions follow semver and are cut automatically by release-please from Conventional Commits on main:
fix: ...→ patch (v0.1.0→v0.1.1)feat: ...→ minor (v0.1.1→v0.2.0)feat!: .../BREAKING CHANGE:footer → major (v0.2.0→v1.0.0)
Every merged PR updates a standing "chore(main): release vX.Y.Z" PR with an auto-generated CHANGELOG.md. Merging that PR:
- tags the release and publishes it on GitHub
- builds and attaches zipped, ready-to-install plugin bundles for linux/darwin/windows × amd64/arm64
- regenerates
server.jsonfrom those exact assets (fresh version + SHA-256 hashes) and publishes it to the official MCP Registry viamcp-publisher, authenticated with GitHub OIDC — no stored secrets
See .github/workflows/release-please.yml and .github/workflows/publish-mcp-registry.yml (also runnable by hand for an existing tag via workflow_dispatch).
