           "MEDIAWIKI_URL": "https://your-wiki.com/api.php"
         }
       }
     }
   }
   

3. Restart Cursor

ChatGPT

ChatGPT connects via HTTP. You need to run the server on a machine ChatGPT can reach.

Requirements: ChatGPT Pro, Plus, Business, Enterprise, or Education account.

Setup

1. Start the server with HTTP mode:

   bash

   # Set your wiki URL
   export MEDIAWIKI_URL="https://your-wiki.com/api.php"
   
   # Generate a secure token
   export MCP_AUTH_TOKEN=$(openssl rand -hex 32)
   echo "Save this token: $MCP_AUTH_TOKEN"
   
   # Start the server
   ./mediawiki-mcp-server -http :8080
   

2. In ChatGPT:

   • Go to Settings → Connectors → Advanced → Developer Mode
   • Add a new MCP connector
   • URL: http://your-server:8080 (must be publicly accessible)
   • Authentication: Bearer token → paste your token

3. Test it: Ask "Search the wiki for getting started"

For production: See Security Best Practices for HTTPS setup.

n8n

n8n connects via HTTP using the MCP Client Tool node.

Setup

1. Start the server with HTTP mode:

   bash

   export MEDIAWIKI_URL="https://your-wiki.com/api.php"
   export MCP_AUTH_TOKEN="your-secure-token"
   ./mediawiki-mcp-server -http :8080
   

2. In n8n:

   • Add an MCP Client Tool node
   • Transport: HTTP Streamable
   • URL: http://your-server:8080
   • Authentication: Bearer → your token

3. Enable for AI agents (add to n8n environment):

   code

   N8N_COMMUNITY_PACKAGES_ALLOW_TOOL_USAGE=true
   

4. Connect the MCP Client Tool to an AI Agent node.

VS Code

VS Code has built-in MCP support via Copilot Chat.

1. Open the Command Palette: Ctrl+Shift+P (Windows) or Cmd+Shift+P (Mac)
2. Type "MCP: Add Server" and select it
3. Choose "Stdio" as the transport type
4. Enter the path to the binary when prompted
5. Name the server: mediawiki

This creates a .vscode/mcp.json file. Add the environment variables:

{
  "servers": {
    "mediawiki": {
      "command": "/path/to/mediawiki-mcp-server",
      "env": {
        "MEDIAWIKI_URL": "https://your-wiki.com/api.php"
      }
    }
  }
}

On Windows, use the .exe path with double backslashes.

Reload VS Code, then use the wiki tools through Copilot Chat.

Google ADK

Google's Agent Development Kit connects to MCP servers via stdio or Streamable HTTP.

import (
    "os/exec"
    "google.golang.org/adk/tool/mcptoolset"
    "github.com/modelcontextprotocol/go-sdk/mcp"
)

// Create MCP toolset for wiki access
wikiTools, _ := mcptoolset.New(mcptoolset.Config{
    Transport: &mcp.CommandTransport{
        Command: exec.Command("/path/to/mediawiki-mcp-server"),
        Env: []string{
            "MEDIAWIKI_URL=https://your-wiki.com/api.php",
        },
    },
})

// Add to your agent
agent := llmagent.New(llmagent.Config{
    Name:     "wiki-agent",
    Model:    model,
    Toolsets: []tool.Set{wikiTools},
})

First, start the server in HTTP mode:

export MEDIAWIKI_URL="https://your-wiki.com/api.php"
./mediawiki-mcp-server -http :8080 -token "your-secret-token"

Then connect from your ADK agent:

import (
    "google.golang.org/adk/tool/mcptoolset"
    "github.com/modelcontextprotocol/go-sdk/mcp"
)

wikiTools, _ := mcptoolset.New(mcptoolset.Config{
    Transport: mcp.NewStreamableHTTPClientTransport("http://localhost:8080"),
})

from google.adk.tools.mcp_tool import MCPToolset, StdioConnectionParams, StdioServerParameters

wiki_tools = MCPToolset(
    connection_params=StdioConnectionParams(
        server_params=StdioServerParameters(
            command="/path/to/mediawiki-mcp-server",
            env={"MEDIAWIKI_URL": "https://your-wiki.com/api.php"},
        )
    )
)

Start the server in HTTP mode, then:

from google.adk.tools.mcp_tool import MCPToolset, StreamableHTTPConnectionParams

wiki_tools = MCPToolset(
    connection_params=StreamableHTTPConnectionParams(
        url="http://localhost:8080",
        headers={"Authorization": "Bearer your-secret-token"},
    )
)

Need to Edit Wiki Pages?

Reading works without login on public wikis. Private/corporate wikis often require authentication for all operations, including reading. Editing always requires a bot password.

Create a Bot Password

1. Log in to your wiki
2. Go to Special:BotPasswords (e.g., https://your-wiki.com/wiki/Special:BotPasswords)
3. Enter a bot name: mcp-assistant
4. Check these permissions:
   • ✅ Basic rights
   • ✅ Edit existing pages
5. Click Create and save the password (you won't see it again)

Add Credentials to Your Config

Claude Desktop / Cursor:

{
  "mcpServers": {
    "mediawiki": {
      "command": "/path/to/mediawiki-mcp-server",
      "env": {
        "MEDIAWIKI_URL": "https://your-wiki.com/api.php",
        "MEDIAWIKI_USERNAME": "YourWikiUsername@mcp-assistant",
        "MEDIAWIKI_PASSWORD": "your-bot-password-here"
      }
    }
  }
}

Claude Code CLI:

claude mcp add mediawiki /path/to/mediawiki-mcp-server \
  -e MEDIAWIKI_URL="https://your-wiki.com/api.php" \
  -e MEDIAWIKI_USERNAME="YourWikiUsername@mcp-assistant" \

Troubleshooting

"MEDIAWIKI_URL environment variable is required" → Check your config file has the correct path and URL.

"authentication failed" → Check username format: WikiUsername@BotName → Verify bot password hasn't expired → Ensure bot has required permissions

"page does not exist" → Page titles are case-sensitive. Check the exact title on your wiki.

Tools not appearing in Claude/Cursor → Restart the application after config changes.

ChatGPT can't connect → Ensure your server is publicly accessible (not just localhost) → Check the bearer token matches exactly

"PDF search requires 'pdftotext'" → Install poppler-utils for your platform (see PDF Search Setup)

PDF Search Setup

PDF search requires the pdftotext tool from poppler-utils. Text file search (TXT, MD, CSV, etc.) works without any dependencies.

Windows alternative: Download binaries from poppler-windows releases and add to PATH.

Verify installation:

pdftotext -v

Compatibility

Works with any wiki: Wikipedia, Fandom, corporate wikis, or any MediaWiki installation.

Advanced Configuration

HTTP Transport Options

For ChatGPT, n8n, and remote access, the server supports HTTP transport.

CLI Flags

Examples

# Basic HTTP server
./mediawiki-mcp-server -http :8080

# With authentication
./mediawiki-mcp-server -http :8080 -token "your-secret-token"

# Restrict to specific origins
./mediawiki-mcp-server -http :8080 -token "secret" \
  -origins "https://chat.openai.com,https://n8n.example.com"

# Bind to localhost only (for use behind reverse proxy)
./mediawiki-mcp-server -http 127.0.0.1:8080 -token "secret"

Security Best Practices

When exposing the server over HTTP:

1. Always Use Authentication

./mediawiki-mcp-server -http :8080 -token "$(openssl rand -hex 32)"

2. Use HTTPS via Reverse Proxy

Example nginx configuration:

server {
    listen 443 ssl;
    server_name mcp.example.com;

    ssl_certificate /path/to/cert.pem;
    ssl_certificate_key /path/to/key.pem;

    location / {
        proxy_pass http://127.0.0.1:8080;
        proxy_http_version 1.1;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

3. Restrict Origins

./mediawiki-mcp-server -http :8080 -token "secret" \
  -origins "https://chat.openai.com"

Built-in Security Features

HTTP Endpoints

When running in HTTP mode, these endpoints are available:

Health Checks

Use /health and /ready for container orchestration:

# Kubernetes example
livenessProbe:
  httpGet:
    path: /health
    port: 8080
readinessProbe:
  httpGet:
    path: /ready
    port: 8080

Tool Discovery

Get a list of all available tools:

curl http://localhost:8080/tools | jq '.categories | keys'

Resilience Monitoring

Check circuit breaker and request deduplication status:

curl http://localhost:8080/status
# Returns: {"circuit_breaker":{"state":"closed",...},"inflight_requests":0}

Environment Variables

All Available Tools

search_and_read ✨ — Eliminates the most common two-call pattern (search then read):

"What does the wiki say about deployment?"
→ Searches, reads top result, returns content + remaining hits as summaries

get_page_summary ✨ — Quick overview without loading full page content:

"What is the API Reference page about?"
→ Returns intro section, categories, section list, and metadata

batch_get_pages ✨ — Fetch up to 50 pages in one call:

"Get the content of Main Page, FAQ, and Getting Started"
→ Returns all three pages in a single API request

get_stale_pages ✨ — Wiki hygiene: find outdated content that needs review:

"Find pages not updated in 90 days"
→ Returns stale pages sorted oldest-first with days since last edit

find_similar_pages - Identifies related content that should be cross-linked or potential duplicates:

"Find pages similar to the API Reference page"
→ Returns similarity scores, common terms, and linking recommendations

compare_topic - Detects inconsistencies in documentation (different values, conflicting info):

"Compare how 'timeout' is described across all pages"
→ Returns page mentions with context snippets and value mismatches

Aggregation ✨ - Use aggregate_by parameter to get compact summaries:

• aggregate_by: "user" → Most active editors
• aggregate_by: "page" → Most edited pages
• aggregate_by: "type" → Change type distribution (edit, new, log)

Edit Response Info ✨ - All edit operations return revision tracking and undo instructions:

{
  "revision": {
    "old_revision": 1234,
    "new_revision": 1235,
    "diff_url": "https://wiki.../index.php?diff=1235&oldid=1234"
  },
  "undo": {
    "instruction": "To undo: use wiki URL or revert to revision 1234",
    "wiki_url": "https://wiki.../index.php?title=...&action=edit&undo=1235"
  }
}

move_page ✨ — Rename pages properly (don't delete and recreate):

"Rename 'Old Guide' to 'Updated Guide'"
→ Moves page, creates redirect, optionally moves talk page

manage_categories ✨ — Quick category management:

"Add category 'API' and remove category 'Deprecated' from this page"
→ Modifies categories without touching page content

Supported formats: PDF (text-based), TXT, MD, CSV, JSON, XML, HTML

PDF requires: poppler-utils installed (see PDF Search Setup)

Themes:

• tieto - Tieto brand colors (Hero Blue #021e57 headings, yellow code highlights)
• neutral - Clean output without custom colors (default)
• dark - Dark mode optimized

Options:

• add_css - Include CSS styling block for branded appearance
• reverse_changelog - Reorder changelog entries newest-first
• prettify_checks - Replace plain checkmarks (✓) with emoji (✅)

Example:

Input:  "# Hello\n**bold** and *italic*"
Output: "= Hello =\n'''bold''' and ''italic''"

Workflow for adding Markdown content to wiki:

1. Convert: mediawiki_convert_markdown → get wikitext
2. Save: mediawiki_edit_page → publish to wiki
