Common questions

Is Gdex MCP safe?

It passed 0 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?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 44 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

GDEX MCP Server

An MCP (Model Context Protocol) server exposing the GDEX (Geoscience Data Exchange) REST API as tools for LLM clients — dataset discovery/metadata, file listings, data access links, ARCO variables, portal/dataset metrics, staff contacts, and authenticated subsetting-request workflows.

Running locally

pip install -e .

gdex-mcp

Then point your MCP client (Claude Desktop, Claude Code, etc.) at the gdex-mcp command. Configuration is via environment variables or a .env file — see CLAUDE.md's Configuration section. Most tools need no configuration at all; set GDEX_TOKEN only if you'll use the subsetting-request tools (list_request_statuses, check_request_status, get_request_files, submit_subset_request, submit_and_wait_for_request, purge_request).

Running as a shared service

Set GDEX_MCP_TRANSPORT=streamable-http (see Dockerfile) to run this as a network-reachable service instead of a local stdio subprocess. In that mode, callers using the subsetting-request tools pass their own GDEX token as an Authorization: Token header on each request rather than relying on a shared GDEX_TOKEN — see CLAUDE.md's "Two transports" section for how that's wired.

Docker

# Build the image

docker build -t gdex-mcp .

Run the container

docker run -d --name gdex-mcp -p 8080:8080 gdex-mcp

MCP requests go to http://localhost:8080/mcp.

# Stop and remove the container

docker stop gdex-mcp && docker rm gdex-mcp

Deployment

A merged PR to main triggers the GitHub Actions workflow, which runs the test suite (pip install -e ".[test]" && pytest) and then builds a new Docker image and pushes it to Harbor (hub.k8s.ucar.edu/gdex_mcp/gdex-mcp). The app is deployed to Kubernetes via the Helm chart in app-chart/ — see CLAUDE.md's Deployment section for how this follows gdex-web-services' conventions.

# Deploy with Helm

helm upgrade --install gdex-mcp ./app-chart -n

Deploy a test instance

helm upgrade --install gdex-mcp ./app-chart -n --set testName=

MCP Registry

gdex-mcp is published to the official MCP Registry as io.github.rpconroy/gdex-mcp (see server.json), not io.github.NCAR/gdex-mcp. Publishing under the NCAR org namespace kept failing with a 403 even after making org membership public — a known, unresolved issue with the registry's org-membership check (see modelcontextprotocol/registry#1537 and #1649), suspected to be an org-admin-side GitHub OAuth App access restriction rather than anything on our end. .github/workflows/publish-mcp-registry.yaml publishes new versions on v* tags; it uses PAT auth (MCP_GITHUB_TOKEN secret) instead of GitHub OIDC because this repo is NCAR-owned, so Actions OIDC always asserts repository_owner: NCAR and can't authenticate as the personal rpconroy namespace. Once NCAR org access is sorted out, moving to io.github.NCAR/gdex-mcp means publishing a new registry entry (the registry has no rename support) and switching the workflow back to login github-oidc.
