GSC MCP server (Session Media, hosted on Railway)

Google Search Console MCP server behind the Claude connector at https://gsc-mcp-server-production-106c.up.railway.app/.

• gsc_server.py is the unmodified upstream AminForou/mcp-gsc (MIT, LICENSE), copied at commit d49eea9 (2026-09-15). To update, copy the new file over and run pytest test_app.py.

• app.py is our hosted entrypoint. It takes the Google login from env vars and keeps it in memory. Upstream's token.json is deleted on any failed refresh, which took the old deployment down on 2026-10-22 until a restart. It also adds OAuth for Claude connectors (signed, stateless tokens, so redeploys don't sign anyone out) and serves streamable HTTP at /.

• Railway builds from Dockerfile (railway.json, healthcheck /health). Pushing to main redeploys.

Railway variables

On boot the log says Google credentials OK: N Search Console properties visible or Google credentials FAILED: <reason> (invalid_grant = the refresh token was revoked; mint a new one).

What's New

[0.4.1] — September 2026

• check_indexing_issues runs concurrently — same fix as #31, so it no longer times out on 10-URL batches against sc-domain:* properties. Thanks @kuldiph. (#55)

• Removed a leftover dead orderBy in get_search_by_page_query (the Search Analytics API ignores it). Thanks @kuldiph. (#55)

[0.4.0] — September 2026

• Rich-result issues now surface — inspect_url_enhanced and batch_url_inspection read rich-result issues from the correct API path, so markup problems are reported instead of silently dropped. Thanks @patrickweh. (#46, #48)

• batch_url_inspection runs concurrently — 10-URL batches no longer time out on sc-domain:* properties. Thanks @remotesensei. (#31)

• compare_search_periods deltas fixed — Period 1 is now the analyzed period and Period 2 the baseline, so growth reads as growth (not decline). Thanks @JKdreaming. (#42)

• get_advanced_search_analytics sorting works — sort_by/sort_direction are now applied instead of silently ignored. Thanks @kuldiph. (#54)

• Hardened error handling — replaced bare except: clauses so fatal signals aren't swallowed. Thanks @kuldiph. (#53)

• Note: batch_url_inspection renames the per-URL verdict field to index_verdict to distinguish it from the rich-result verdict.

[0.3.3] — July 2026

• Fixed fresh installs broken by mcp 2.0 — pinned mcp[cli]<2.0.0. The mcp SDK 2.0.0 (released 2026-07-28) removed the mcp.server.fastmcp module, so every fresh uvx mcp-search-console install crashed on startup with ModuleNotFoundError: No module named 'mcp.server.fastmcp'. New installs now resolve a working 1.x SDK again — no --with "mcp<2" workaround needed.

[0.3.2] — April 2026

• OAuth browser flow fixed for uvx — removed the isatty block that prevented the browser login window from opening when running as an MCP subprocess on macOS. OAuth now works out of the box with uvx, no manual terminal run needed.

• get_capabilities tool added — call this to get a full list of available tools and current auth status in one shot. Useful when your AI assistant isn't sure what tools are available.

• Better auth error messages — all tools now tell you exactly what to do when credentials are missing or expired.

Getting Started

Step 1 — Set Up Google API Credentials

You need credentials before configuring any client. Pick one method:

Option A — OAuth (Recommended — uses your own Google account)

1. Go to Google Cloud Console and create or select a project

2. Enable the Search Console API

3. Go to Credentials → Create Credentials → OAuth client ID

4. Configure the OAuth consent screen, select Desktop app, click Create

5. Download the JSON file — save it somewhere permanent (e.g. ~/Documents/client_secrets.json)

On first use, a browser window will open asking you to sign in to your Google account. After that, the token is saved and no browser interaction is needed again.

Option B — Service Account (For automation or team use)

1. Go to Google Cloud Console and create or select a project

2. Enable the Search Console API

3. Go to Credentials → Create Credentials → Service Account

4. Go to the Keys tab → Add Key → Create new key → JSON → Download

5. Save the file somewhere permanent (e.g. ~/Documents/service_account.json)

6. Add the service account email to your GSC property: Search Console → Settings → Users and permissions → Add user → Full access

🎥 Watch the step-by-step setup tutorial for this section

Updated 2026 — covers the full installation process using the new uvx method, from setting up your Google credentials to your first successful query.

Step 2 — Installation

Option A — uvx (Recommended)

No cloning, no Python installation, no virtual environments. uvx downloads and runs the server automatically and keeps it up to date.

Install uv — open Terminal and run all three commands in order:

# 1. Download and install
curl -LsSf https://astral.sh/uv/install.sh | sh

# 2. Activate in the current Terminal session
source $HOME/.local/bin/env

# 3. Make it permanent for all future sessions
echo 'source $HOME/.local/bin/env' >> ~/.zshrc

Verify:

uv --version

Why all three commands? The installer puts uv in ~/.local/bin, but your already-open Terminal session doesn't know about that folder yet. Step 2 activates it immediately. Step 3 ensures every future Terminal window has it automatically.

Now configure your AI client:

Claude Desktop

Config file: ~/Library/Application Support/Claude/claude_desktop_config.json

OAuth:

{
  "mcpServers": {
    "gscServer": {
      "command": "/FULL/PATH/TO/uvx",
      "args": ["mcp-search-console"],
      "env": {
        "GSC_OAUTH_CLIENT_SECRETS_FILE": "/full/path/to/client_secrets.json"
      }
    }
  }
}

Service Account:

{
  "mcpServers": {
    "gscServer": {
      "command": "/FULL/PATH/TO/uvx",
      "args": ["mcp-search-console"],
      "env": {
        "GSC_CREDENTIALS_PATH": "/full/path/to/service_account.json",
        "GSC_SKIP_OAUTH": "true"
      }
    }
  }
}

Cursor

Config file: ~/.cursor/mcp.json

OAuth:

{
  "mcpServers": {
    "gscServer": {
      "command": "/FULL/PATH/TO/uvx",
      "args": ["mcp-search-console"],
      "env": {
        "GSC_OAUTH_CLIENT_SECRETS_FILE": "/full/path/to/client_secrets.json"
      }
    }
  }
}

Codex CLI

Config file: ~/.codex/config.toml

OAuth:

[mcp_servers.gscServer]
command = "/FULL/PATH/TO/uvx"
args = ["mcp-search-console"]
enabled = true
env = { GSC_OAUTH_CLIENT_SECRETS_FILE = "/full/path/to/client_secrets.json" }

Service Account:

[mcp_servers.gscServer]
command = "/FULL/PATH/TO/uvx"
args = ["mcp-search-console"]
enabled = true
env = { GSC_CREDENTIALS_PATH = "/full/path/to/service_account.json", GSC_SKIP_OAUTH = "true" }

Finding your uvx path: On macOS/Linux run which uvx in Terminal after installing uv (typically /Users/YOUR_NAME/.local/bin/uvx). On Windows, run Get-Command uvx | Select-Object -ExpandProperty Source in PowerShell (or where uvx in cmd) — it's usually C:\Users\YOUR_NAME\.local\bin\uvx.exe. Replace /FULL/PATH/TO/uvx in the configs above with that path.

Why the full path? GUI apps like Claude Desktop and Cursor launch without reading your shell config (~/.zshrc), so they don't know about ~/.local/bin. Using the full path guarantees it works regardless of how the app is launched. If you see a spawn uvx ENOENT error, this is the fix.

After saving the config, fully quit the app (Cmd+Q) and reopen it.

For OAuth: on first use, a browser window will open automatically for login. After that, the token is cached and you won't be asked again.

Option B — Clone (Advanced)

Prefer a video walkthrough for this method? The tutorial below covers the clone install path step by step — virtual environment setup, dependencies, and config:

Use this if you want to modify the code or run a specific local version. This method uses the video tutorial above for the credential setup steps.

Requires Python 3.11+. This server will not start on Python 3.10 or older — and when it's launched by a GUI client like Claude Desktop, it fails silently (no tools appear and no log file is written). Check your version with python --version. If it's below 3.11, install Python 3.11 or newer and recreate your virtual environment. The uvx method (Option A) avoids this entirely by managing the Python version for you, so it's the recommended path on Windows.

Clone the repo:

git clone https://github.com/AminForou/mcp-gsc.git
cd mcp-gsc

Or download the ZIP from the green Code button at the top of this page and unzip it.

Set up the environment:

uv venv .venv
uv pip install -r requirements.txt

Configure your AI client (Claude Desktop example):

OAuth:

{
  "mcpServers": {
    "gscServer": {
      "command": "/full/path/to/mcp-gsc/.venv/bin/python",
      "args": ["/full/path/to/mcp-gsc/gsc_server.py"],
      "env": {
        "GSC_OAUTH_CLIENT_SECRETS_FILE": "/full/path/to/client_secrets.json"
      }
    }
  }
}

Service Account:

{
  "mcpServers": {
    "gscServer": {
      "command": "/full/path/to/mcp-gsc/.venv/bin/python",
      "args": ["/full/path/to/mcp-gsc/gsc_server.py"],
      "env": {
        "GSC_CREDENTIALS_PATH": "/full/path/to/service_account.json",
        "GSC_SKIP_OAUTH": "true"
      }
    }
  }
}

Mac path examples:

• Python: /Users/yourname/Documents/mcp-gsc/.venv/bin/python

• Script: /Users/yourname/Documents/mcp-gsc/gsc_server.py

Step 3 — Test

Ask your AI assistant: "List my GSC properties"

If you see your properties — it's working. If not, ask: "Call get_capabilities" to see auth status and diagnose the issue.

Environment Variables Reference

Cursor Marketplace

One-click install available — search for mcp-search-console in the Cursor Marketplace.

After installing, configure your credentials (see Step 1 above) then use the bundled skills directly in Cursor Agent chat:

Sample Prompts

Troubleshooting

spawn uvx ENOENT or command not found: uvx

Your AI client can't find uvx. Use the full path instead of just uvx:

# Find your full path (macOS/Linux):
which uvx
# Typically: /Users/YOUR_NAME/.local/bin/uvx

# Find your full path (Windows PowerShell):
Get-Command uvx | Select-Object -ExpandProperty Source
# Typically: C:\Users\YOUR_NAME\.local\bin\uvx.exe

Replace "command": "uvx" with the full path (e.g. "command": "/Users/YOUR_NAME/.local/bin/uvx") in your config.

uv --version gives "command not found" right after installing

The installer updates ~/.local/bin but your current Terminal session doesn't see it yet. Run:

source $HOME/.local/bin/env

Then add it permanently:

echo 'source $HOME/.local/bin/env' >> ~/.zshrc

Authentication failed / credentials file not found

Make sure you are using the absolute path to your credentials file — not a relative path, not ~/. Example:

/Users/yourname/Documents/client_secrets.json   ✅
~/Documents/client_secrets.json                 ✅
client_secrets.json                              ❌

MCP only works in Claude Desktop app, not the website

The MCP server runs locally on your machine. It only works in the Claude Desktop app (downloaded from claude.ai/download), not in the claude.ai browser interface.

AI Client Configuration Issues

1. Make sure all file paths in your config are correct absolute paths

2. Fully quit (Cmd+Q) and reopen the app after any config change — just closing the window is not enough

3. Ask your AI assistant to "call get_capabilities" — it will report the exact auth status and error

Safety: Destructive Operations

By default, add_site, delete_site, and delete_sitemap are disabled. To enable them:

"GSC_ALLOW_DESTRUCTIVE": "true"

Remote Deployment & Docker (Advanced)

The standard setup runs the server locally. This section is only for users who want to run it on a remote server or in a container.

HTTP Transport

MCP_TRANSPORT=sse MCP_HOST=0.0.0.0 MCP_PORT=3001 python gsc_server.py

Docker

docker build -t mcp-gsc .

docker run \
  -e MCP_TRANSPORT=sse \
  -e MCP_HOST=0.0.0.0 \
  -e MCP_PORT=3001 \
  -e GSC_CREDENTIALS_PATH=/app/credentials.json \
  -v /path/to/credentials.json:/app/credentials.json \
  -p 3001:3001 \

Changelog

[0.4.1] — September 2026

• check_indexing_issues now inspects URLs concurrently (same fix as #31), avoiding timeouts on full 10-URL batches against sc-domain:* properties. (Fixes #55; thanks @kuldiph)

• Removed a leftover orderBy from get_search_by_page_query — a dead field the Search Analytics API ignores, matching the #54 cleanup. (Fixes #55; thanks @kuldiph)

[0.4.0] — September 2026

• Fixed rich-result issue reporting in inspect_url_enhanced and batch_url_inspection — issues are read from detectedItems[].items[].issues[] (issueMessage), the key the API actually returns, so problems are no longer silently dropped. (Fixes #46, #48; thanks @patrickweh)

• batch_url_inspection now inspects URLs concurrently, so full 10-URL batches complete within the client timeout even on slower sc-domain:* properties. (Fixes #31; thanks @remotesensei)

• compare_search_periods now computes deltas as Period 1 relative to Period 2 (Period 2 as the percentage baseline, positive = Period 1 better), with the direction documented. (Fixes #42; thanks @JKdreaming)

• get_advanced_search_analytics applies sort_by/sort_direction client-side instead of sending an orderBy the Search Analytics API ignores. (Fixes #54; thanks @kuldiph)

• Replaced three bare except: clauses with except Exception: so KeyboardInterrupt/SystemExit are no longer swallowed. (Fixes #53; thanks @kuldiph)

• Breaking: batch_url_inspection renames the per-URL verdict field to index_verdict.

[0.3.3] — July 2026

• Pinned mcp[cli]>=1.3.0,<2.0.0. The mcp SDK 2.0.0 removed mcp.server.fastmcp, breaking all fresh uvx installs with ModuleNotFoundError. Capping below 2.0 restores working installs. (Fixes #41)
