For AI agents — MCPBundles Directory API
Recommended: Directory API v1 over HTTP for detail and anonymous invoke when eligible (not MCP JSON-RPC on the publisher URL; no user MCPBundles credentials on v1).
GET https://www.mcpbundles.com/api/directory/v1/servers/volts-mcp-1a5ecadc1d
GET https://www.mcpbundles.com/api/directory/v1/servers/volts-mcp-1a5ecadc1d?live=1 (optional live refresh)
GET https://www.mcpbundles.com/api/directory/v1/servers/volts-mcp-1a5ecadc1d/tools/<tool> (one tool: schema + invoke.url)
POST https://www.mcpbundles.com/api/directory/v1/servers/volts-mcp-1a5ecadc1d/tools/{tool}
POST body: flat JSON of tool argument names and values; not an arguments wrapper. Replace {tool} with a tool name from GET detail.
Restricted agent shell (ChatGPT Codex desktop, some IDE sandboxes):
Default command sandboxes often block outbound network. curl exit 6 or "Could not resolve host" for www.mcpbundles.com is usually sandbox DNS — not evidence this site is down.
Retry the same Directory API GET with sandbox_permissions "require_escalated" and a one-sentence justification on the shell tool (Codex on-request approval). Do not tell the user the site is unreachable from sandbox curl alone.
Example justification: Run the public MCPBundles Directory API search outside the command sandbox to complete the user's MCP server lookup.
If the agent has browser access (e.g. Codex @Browser): open https://www.mcpbundles.com/?q=<query> or stay on this page — no shell network needed. Use WebMCP search_mcp_servers then get_mcp_server (document.modelContext / page tools; refresh with fetchTools or getTools if a tool id is missing from the snapshot). Read-only directory search; same index as Directory API v1 GETs. Neither WebMCP nor Directory API v1 uses user MCPBundles credentials.
Without a browser: after escalated curl fails, use GET https://www.mcpbundles.com/?q=<query> with Accept: text/markdown for ranked results.
Hub MCP (connected session): discover_mcp_servers — same filter semantics as search_mcp_servers.

Get Current Time
read
get_current_time
PURPOSE:
Return the current date and time in the user's timezone (Europe/Sofia).
WHEN TO USE:
- Before handling ANY date-related query (e.g., "today", "yesterday", "this month", "last month").
- Before converting natural language periods into concrete ISO dates for consumption/comparison tools.
OUTPUT:
- Current date/time as an ISO 8601 string.
Get Current Time — PURPOSE:
Return the current date and time in the user's timezone (Europe/Sofia).
WHEN TO USE:
- Before handling ANY date-related query (e.g., "today", "yesterday", "this month", "last month").
- Before converting natural language periods into concrete ISO dates for consumption/comparison tools.
OUTPUT:
- Current date/time as an ISO 8601 string.
Get User Devices — Get user's or organization's devices and their feeds.
PREREQUISITE: MUST call this before get_historical_feed_data or compare_consumption to get feed IDs.
Do NOT pass measurement_type unless scope.module is set or user explicitly requests a type.
Without measurement_type, returns ALL devices (energy, water, gas, etc.).
For user-defined metadata, use `get_user_device_custom_fields`.
Present results: "Total: X devices." then briefly list 3-5 main devices. Refer user to CSV for full list. No IDs
Get User Device Custom Fields — Get business metadata (custom fields) for devices. Use instead of get_user_devices when user asks about subscriber/account/address/install date etc.
Get Volts Docs — Volts PRODUCT DOCUMENTATION (manuals, datasheets, install guides, specs).
This is the ONLY source for product documentation. Do NOT call get_user_devices
for "documentation", "manual", "datasheet", "spec sheet" — those questions are
about the product itself, not the user's specific installed devices.
WHEN TO USE — call this tool when the user asks any of:
- "documentation" / "docs" / "manual" / "datasheet" / "spec sheet" /
"specifications" / "user guide" / "quick start" / "package contents"
Get My Places — Get all places (properties/locations) where devices are installed.
Use to discover place IDs for consumption queries and location reports.
Present places by name naturally. No IDs unless asked.
Get My Tariffs — Get electricity tariff information (pricing structure, rates, costs).
Returns tariff names, price components, subtariffs (day/night rates), and rate periods.
Get Relay Circuit Name
Get your MCP into directories
A working endpoint is step one. Directory coverage is the coordinated launch across ChatGPT, Claude, Cursor, the MCP Registry, and community indexes.
Volts is an MCP server at api.volts.live. MCPBundles discovered 21 tools on the live endpoint.
How do I connect Volts to my AI agent?
Use the MCP endpoint listed on this page in your MCP client configuration. One-click install pills support Claude, Cursor, VS Code, and other hosts. Copy the remote MCP URL if your client needs a manual entry.

Operate Volts?
This server appears in the MCPBundles directory. Verify you operate it to take over the listing — name, description, logo, contact email, and skill content. We email a 6-digit code to a maintainer address your server publishes in /.well-known/security.txt or /.well-known/mcpbundles.json. Free, takes about a minute.
MCPBundles publishes this directory for MCP discovery. Except where we host or operate an offering, third-party services run under their own terms. Product and company names on this page are used in a descriptive, identifying way (including under nominative fair use where applicable); they remain the property of their owners. Nothing here grants you rights in those marks, and nothing here is an offer to sell a third party's services. Terms · Request removal

Other MCP servers in this category from the directory index
— Get all available relay circuit names for a specific device.
Use this tool to find the `circuit_index` for a given circuit name on a specific device.
The `circuit_index` is required to set the state of a relay.
Set Relay State — Set the state of a relay device to 'on' or 'off'.
Use this tool to control smart plugs, lights, or other switchable devices.
First, use `get_relay_circuits` to find the correct `circuit_index`.
Get Historical Feed Data — Get feed data (consumption, measurements, values) for a specific feed over a time period.
PREREQUISITE: Call get_user_devices() first to obtain the feed_id. Never guess feed IDs.
DATE RULES (MUST FOLLOW):
Format: YYYY-MM-DD (ISO 8601)
Monthly: to_date = 1st of NEXT month (Sep → to="2025-10-01", NOT "2025-09-30")
"this month" = 1st of current month → today
"last month" = 1st of prev month → 1st of current month
PREREQUISITE: Call get_current_time() first for any relative date.
FEED T
Compare Consumption — Compare consumption between two time periods for a feed.
Same feed matching and date rules as get_historical_feed_data.
Monthly: to_date = 1st of NEXT month (Sep → "2024-10-01", NOT "2024-09-30").
PREREQUISITE: Call get_current_time() first for relative dates.
DATE EXAMPLES:
- "Sep vs Oct" → first: "2024-09-01"→"2024-10-01", second: "2024-10-01"→"2024-11-01"
- "this month vs last month" → calculate from current date
Get Place Consumption Total — DATE RULES (MUST FOLLOW):
Format: YYYY-MM-DD (ISO 8601)
Monthly: to_date = 1st of NEXT month (Sep → to="2025-10-01", NOT "2025-09-30")
PREREQUISITE: Call get_current_time() first for any relative date ("today", "this month", etc.)
Get Place Consumption History — DATE RULES (MUST FOLLOW):
Format: YYYY-MM-DD (ISO 8601)
Monthly: to_date = 1st of NEXT month (Sep → to="2025-10-01", NOT "2025-09-30")
PREREQUISITE: Call get_current_time() first for any relative date.
Create Tariff — Create a new electricity tariff with pricing periods and rates.
CRITICAL: Price components and subtariffs CANNOT be managed separately.
They MUST be created at tariff creation time. To modify them later,
update the tariff with the complete revised structures.
Each tariff should include:
- At least one price component (e.g., "energy", "network")
- At least one subtariff with continuous 24-hour time intervals (0-24)
- Optionally, pricing periods with rates
DETAILED FIELD SPECIFICATIONS:
Update Tariff — Update an existing tariff including its name, price components, subtariffs, and periods.
IMPORTANT: To modify price components or subtariffs, provide the COMPLETE revised lists.
All nested structures within the tariff are managed through this tool only.
There are no separate tools for managing components and subtariffs.
Delete Tariff — Delete a tariff permanently.
IMPORTANT: This action cannot be undone.
List Reports — PURPOSE:
List all scheduled reports configured for the user (or organization).
WHEN TO USE:
- User asks "what reports do I have", "show my reports", "list scheduled reports".
- Before update/delete/generate to look up the report ID by name.
OUTPUT:
CSV with ID, Name, Type, Periodicity (weekly/monthly), ReportDay,
Enabled, FeedCount, EmailCount, UpdatedAt.
Get Report — Get full details of one report by ID, including its configured feeds and email recipients.
Create Report — Create a new scheduled report.
REQUIRED ARGUMENTS — every call MUST include all three of these in the
tool-call payload, or the request fails Pydantic validation BEFORE the
server is even reached:
- report_name (str)
- feeds (list of dicts, e.g. [{"device_id": 631, "feed_id": 369}])
- emails (list of str, e.g. ["alice@x.com"])
Asking the user for these values is step 1; PASSING THEM IN THE TOOL
CALL is step 2 — the asking does not replace the call argument. After
the user confirms, immedi
Update Report — Update an existing report. Only the fields you pass are changed.
IMPORTANT: when updating feeds or emails, pass the COMPLETE replacement list
(not a delta) — the server replaces the whole list.
Delete Report — Delete a scheduled report. THIS ACTION IS PERMANENT AND CANNOT BE UNDONE.
CONFIRMATION REQUIRED — DO NOT call this tool on the user's first
delete request. Instead:
1. Call get_report(report_id) to fetch the report's name and details.
2. Show the user what will be deleted: "You're about to delete
'<report name>' (id <id>) — <feed count> feeds, <email count>
recipients. This cannot be undone. Confirm with 'yes, delete it'."
3. Only call delete_report after the user replies with a
Generate Report Now — Generate a report PDF immediately and save it to disk.
Without from_date/to_date, the API returns the report for the current period
(week or month, per the report's configured periodicity).
