## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-06.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server, and every tool looks verifiably read-only (it declares readOnlyHint: true, starts its name with a read verb and describes no write), so an anonymous caller can read but cannot change anything. We can't see whether a tool returns data specific to one caller, so keep any per-user data behind authorisation.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 403, which proves neither a plaintext path nor enforcement.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 77/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1019 tokens (~254/item across 4 items; 3 tools + 1 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 100/100
  - No destabilizing schema changes in the last 30 days.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.
  - Supports UI / widget rendering.

## MCP tools (3)

### `check_fibre_availability` (~479 tokens)

Check fibre broadband availability

Check which fibre and broadband deals are available at a UK postcode (or exact address via UPRN/UDPRN) using fibrecompare.com. Returns providers, download speeds, monthly prices, contract lengths, key features and a sign-up link for each deal. Optionally filter by minimum speed, maximum price, provider or contract length.

Input parameters:

- `address` (string): House number/name and optionally street, e.g. '12', 'Flat 3, 12', 'Rose Cottage'. If it matches one premises at the postcode the check is done at address level in this same call.
- `address_key` (string): An address_key from a previous result's addresses list. Runs the check for that exact premises.
- `limit` (integer): Maximum number of deals to return (default 5). The full list is always available at view_more_url.
- `max_contract_months` (integer): Only return deals with a contract of at most this many months (0 = rolling/no contract).
- `max_monthly_cost_gbp` (number): Only return deals costing at most this much per month in GBP.
- `min_download_mbps` (number): Only return deals whose average download speed is at least this many Mbps (e.g. 100, 500, 900).

- `udprn` (string): Royal Mail Unique Delivery Point Reference Number, if known and no UPRN is available.
- `uprn` (string): Unique Property Reference Number for the exact premises, if known. Gives an address-level rather than postcode-level answer.
- `visitor_id` (string): The visitor_id from a previous result in this conversation. Reuse it so checks and deal clicks are attributed to the same visit. Omit on the first call.

Output parameters:

- `address_level` (string)
- `addresses` (array): For postcode-level results: the premises at this postcode. Pass one's address_key back to get an exact-address check.

- `display_address` (string)
- `postcode` (string)
- `returned_deals` (number)
- `total_deals` (number)

## Common questions

### What is the Fibre Compare MCP server?

Fibre Compare is an MCP server listed in the public MCP registry as com.fibrecompare/availability. Check which fibre and broadband deals are available at a UK postcode or address (fibrecompare.com). This page covers its hosted endpoint (https://fibrecompare.com/mcp).

### Is the Fibre Compare MCP server safe to use?

Fibre Compare scores 88 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 Fibre Compare MCP server expose?

Fibre Compare exposes 3 tools: check_fibre_availability, search, fetch. Their descriptions and schemas cost roughly 625 tokens of context every time the server is loaded.

### Does the Fibre Compare MCP server require authentication?

No. We connected to Fibre Compare without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Fibre Compare MCP server still maintained?

Fibre Compare is still listed as active in the MCP registry. We last reached this channel on 6 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the Fibre Compare MCP server?

VerifyMCP ran 13 checks on Fibre Compare, covering TLS certificate, Authorization, HSTS header, DNSSEC and 9 more. One item could not be completed, a gap on our side rather than a finding about Fibre Compare: HTTPS. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
