Hashproof vs Horizon Shield
A side-by-side look at the Hashproof and Horizon Shield MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Hashproof for cryptography work as a local process; choose Horizon Shield for cryptography over a hosted endpoint. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Hashproof when
- You need dedicated capabilities in the Cryptography domain.
- You prefer a local stdio subprocess transport.
Choose Horizon Shield when
- You need dedicated capabilities in the Cryptography domain.
- You prefer a remote HTTP/SSE transport.
- You want tools like
get_price_range, audit_estimate, verify_fair_price.

Horizon Shield tools 29
get_price_rangeReturns the fair price range (min, avg, max), the overcharge danger threshold, unit, price trend, and field notes for a Japanese construction or renovation job.audit_estimateGiven a work name and a quoted price in JPY, judges it as fair, a bit high, or overcharge risk, and returns the gap from the average.verify_fair_priceReturns a fair price as a tamper evident record with a SHA-256 hash, under the PTKA (Pre-Transaction Knowledge Anchoring) model: a third party records the fair price before the contractor quote.check_red_flagsChecks whether wording in an estimate or sales pitch matches known overcharge or high pressure tactics (lump sum, today only discount, free inspection, door to door). Language agnostic.get_estimate_reading_guideReturns universal principles for judging whether any estimate is honest: the overhead ratio, how to treat lump sum entries, how to spot pressure tactics. Language agnostic.list_cost_categoriesLists the construction and renovation work categories for which fair price ranges and red flags are maintained.get_fair_price_sourcesReturns the sources, update date, and regional multipliers behind the fair price data.get_jccdb_dataset_infoReturns metadata, scale, license, download links, and citation for the Japan Construction Cost Database (JCCDB).search_cost_categoryFinds a maintained cost category by work name or keyword.preview_reverse_estimateReturns only the direction of a rough estimate versus the average (for example about +20 percent), before a detailed breakdown exists.
Ready-to-paste client configs
Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.

Frequently asked questions
Hashproof is categorized under Cryptography and uses a local stdio subprocess. Horizon Shield belongs to Cryptography and uses a remote HTTP/SSE transport. Pick Hashproof for cryptography work and Horizon Shield for cryptography.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Hashproof has no declared pricing — check the project's own site. Horizon Shield has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add hashproof and ogasurfproject-jpg-horizon-shield-3 as separate keys in the same mcpServers object, and your assistant will call tools from either one.
On AllMCPs, Hashproof has a quality signal of 44/100 (Fair) with 0 views, 0 installs and 1 GitHub stars. Horizon Shield has 56/100 (Good) with 1 views, 0 installs and 2 GitHub stars.
