Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security77
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability51
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 2746 tokens (~1373/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management17
- Stability observed for 5 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 3 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
How do I install the BuildBatch MCP server?
BuildBatch is a hosted endpoint at https://buildbatch.co.uk/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

No output schema declared.
No examples provided.
find_guide Find a BuildBatch guide ~80
Finds BuildBatch's guides for a decorating or flooring question (how long between coats, how many tiles in a square metre, what to buy to lay laminate), and returns up to three with each guide's own short answers and its address. It does not work out quantities for a room.

quick_room_list What to buy for a room (quick) ~475
Works out how much paint, wallpaper, wall tiles, flooring, carpet, skirting, loft insulation, plasterboard or concrete one room needs, and everything else to buy for the job (preparation, tools, safety), in real UK pack sizes. Takes the job and either the room's length, width and height, or a typical room by name for a room that has not been measured; the answer then states that the measurements are typical. Returns a short shopping list and a link to the whole list. It does not take exact door sizes, a product's own coverage or pack size, tiling part-way up a wall or an L-shaped room.

What is the BuildBatch MCP server?
BuildBatch is an MCP server listed in the public MCP registry as uk.co.buildbatch/buildbatch. UK DIY shopping lists for one room: paint, wallpaper, tiles, flooring and more, in real packs. This page covers its hosted endpoint (https://buildbatch.co.uk/mcp).
Is the BuildBatch MCP server safe to use?
BuildBatch scores 70 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.
What tools does the BuildBatch MCP server expose?
BuildBatch exposes 4 tools: quick_room_list, plan_room, find_guide, ask_questions. Their descriptions and schemas cost roughly 3,323 tokens of context every time the server is loaded.
Does the BuildBatch MCP server require authentication?
No. We connected to BuildBatch without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the BuildBatch MCP server still maintained?
BuildBatch is still listed as active in the MCP registry. We last reached this channel on 7 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
