MCP - A way for AI Assistants to interact with changedetection.io

Connect AI assistants with MCP

MCP (Model Context Protocol) is an open standard that lets AI assistants such as Claude, ChatGPT, Cursor and VS Code use other applications as tools.

Switch on the MCP and OAuth endpoints

Off: the MCP and OAuth endpoints are switched off and no assistant can connect. Everything here can still be set up first.

Off

Get started

Switch on the MCP server Tick the box above, then Save.
Add an access token Every assistant needs one to connect.
Connect an assistant Copy the command or config for your assistant.

Look

List monitors and groups, what changed between two dates, diffs, page snapshots, errors and what is being checked right now.

Change

Add monitors, change their settings, tag them, recheck them and set up notifications, as far as the permissions allow.

Safe by default

Text from monitored pages is passed on to the assistant as data. Notification URLs are never shown to it in full.

Server

Server address

http://watch.flyhare.com/mcp/v1

MCP access token

Add a token for each assistant on the Access tokens sub-tab. It is shown once, when it is created.

Treat it like a password. It does not expire, and anyone who has it can use these tools and read what they return. Never paste it into a file you commit or share.

Most assistants below can read it from an environment variable, so it stays out of their config files. Set it once, for example in ~/.bashrc or ~/.zshrc:

export CDIO_MCP_TOKEN=YOUR_MCP_TOKEN

Claude Code

Run this in a terminal, then start a new Claude Code session and ask, for example, "Which of my monitors have errors?"

claude mcp add --transport http changedetection http://watch.flyhare.com/mcp/v1 --header "Authorization: Bearer $CDIO_MCP_TOKEN"

To remove it again: claude mcp remove changedetection

By default (--scope local) Claude Code saves this in ~/.claude.json, only for you and only in the current project. Add --scope user to have it in all your projects.

--scope project writes .mcp.json into the project, which is usually committed. Use this form there instead, it saves a reference to the environment variable, not the token:

claude mcp add --transport http --scope project changedetection http://watch.flyhare.com/mcp/v1 --header 'Authorization: Bearer ${CDIO_MCP_TOKEN}'

Cursor ~/.cursor/mcp.json

{"mcpServers": {"changedetection": {"url": "http://watch.flyhare.com/mcp/v1", "headers": {"Authorization": "Bearer ${env:CDIO_MCP_TOKEN}"}}}}

VS Code / GitHub Copilot .vscode/mcp.json

VS Code asks for the token once and stores it securely, so this file is safe to commit.

{"inputs": [{"type": "promptString", "id": "cdio-mcp-token", "description": "changedetection.io MCP access token", "password": true}], "servers": {"changedetection": {"type": "http", "url": "http://watch.flyhare.com/mcp/v1", "headers": {"Authorization": "Bearer ${input:cdio-mcp-token}"}}}}

OpenAI Codex ~/.codex/config.toml

[mcp_servers.changedetection]
url = "http://watch.flyhare.com/mcp/v1"
bearer_token_env_var = "CDIO_MCP_TOKEN"

OpenCode opencode.json

{"mcp": {"changedetection": {"type": "remote", "url": "http://watch.flyhare.com/mcp/v1", "oauth": false, "headers": {"Authorization": "Bearer {env:CDIO_MCP_TOKEN}"}}}}

Gemini CLI ~/.gemini/settings.json

Uses httpUrl, not url (url means the older SSE transport).
