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 Security80
- 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
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability61
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 2312 tokens (~330/item across 7 items; 7 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 Management97
- Stability observed for 29 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage96
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 86% of tool parameters carry a description.Partial
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- All 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation.Pass
- An AI judge read all 8 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

get_business_agent ~170
The canonical ids and endpoint URLs for one business — its own MCP and A2A endpoints, agent card, llms.txt and public page, under `protocol_urls`. A null URL means that surface is switched off for this business right now: do not construct it yourself, and use one of the non-null surfaces instead.

get_business_services ~469
One business's service catalogue, with filtering, sorting and pagination. Page with `offset`/`limit` and read `has_more` — the order is stable, so a second page will not repeat or skip a service.

search_businesses ~831
Search the CoreLoop business directory. Start here: every other tool on this endpoint needs a business, and each result carries the `business_id` and `slug` you pass to them as the `business` argument. `business_id` is a PUBLIC, OPAQUE, STABLE routing identifier: it is safe to store and re-use across sessions, it stays the same when a business renames itself or changes its slug, and it carries no sensitive information. Treat it as a token — do not parse it, do not derive meaning from its format, and do not construct one. Pass back exactly the value you were given. A result with `asserts_no_physical_location: true` has stated that it has no premises (consultants, trades, online-only) — it is intentionally absent from city search rather than missing data. `false` means no such statement was made; it does NOT imply premises. Results are returned in your requested language when the business has published a translation: send `?locale=<code>` on the endpoint URL (takes precedence) or an Accept-Language header. Each result reports the language it is written in (`locale`), the business's original language (`content_locale`), and every language it is available in (`available_locales`). `mcp_url`, `a2a_url` and `page_url` — and every URL inside `protocol_urls` — are null when that surface is currently switched off for the business: a null is intentional (do not construct the URL yourself), and the business remains reachable through its non-null surfaces. `data_source: "directory"` marks these rows as the search projection; call get_business_info for the live profile. PAGING: one call returns at most `limit` results. Read `has_more` — a short page is not proof of the end — and pass `next_cursor` back as `cursor` for the next page. The cursor is opaque and bound to the filters and sort it was issued for: change any of them and it is rejected, so start a new search instead. `limit` may change between pages.

send_business_inquiry ~202
Send a message to one business. This has a real side effect — it notifies the owner and delivers an email — and is rate-limited both per business and across this directory, so send one considered inquiry rather than a broadcast.

How do I install the CoreLoop Business Network MCP server?
CoreLoop Business Network is a hosted endpoint at https://coreloop.so/api/mcp/coreloop-directory, 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.

What is the CoreLoop Business Network MCP server?
CoreLoop Business Network is an MCP server listed in the public MCP registry as so.coreloop/directory. Search real businesses, then read profiles, services and hours or contact them, in one endpoint. This page covers its hosted endpoint (https://coreloop.so/api/mcp/coreloop-directory).
Is the CoreLoop Business Network MCP server safe to use?
CoreLoop Business Network scores 84 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 CoreLoop Business Network MCP server expose?
CoreLoop Business Network exposes 7 tools: search_businesses, check_business_availability, compare_business_services, get_business_agent, get_business_info, and 2 more. Their descriptions and schemas cost roughly 2,207 tokens of context every time the server is loaded.
Does the CoreLoop Business Network MCP server require authentication?
No. We connected to CoreLoop Business Network without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the CoreLoop Business Network MCP server still maintained?
CoreLoop Business Network is still listed as active in the MCP registry. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
