Side-by-Side Model Context Protocol Comparison
Horizon Shield vs Scrivener MCP
In-depth architectural comparison of the Horizon Shield and Scrivener MCP MCP servers. Compare execution transports, security boundaries, tool capabilities, quality scores, and ready-to-paste client installation snippets for Claude, Cursor, Windsurf, and VS Code.
At a Glance & Executive Verdict
Horizon Shield
Cryptography · Local stdio
Quality: 55/100 (Good) | Auth: No auth required
Scrivener MCP
Knowledge & Memory · Local stdio
Quality: 61/100 (Good) | Auth: No auth required
Verdict Summary: Choose Horizon Shield if you need specialized Cryptography tools running via a local process. Choose Scrivener MCP if your workspace requires Knowledge & Memory integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Horizon Shield when:
You need dedicated capabilities in the Cryptography domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Bitcoin-anchored, trustless public verification ledger (JIDEC) for AI-agent evidence: fetch the record bytes, recompute the SHA-256, and check the OpenTimestamps/Bitcoin timestamp — no trust in the issuer required.
Connect Scrivener 3 writing projects to Claude and other AI assistants. 47 tools for document management, writing analysis, semantic search, character/plot memory, and content enhancement. Progressive skill loading, relationship engine with HMS triplets, and JS fallback for offline semantic search. npm i -g scrivener-mcp
Category & Scope
Tools & Capabilities Breakdown
Horizon Shield Tools (14)
get_price_range
Returns 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_estimate
Given 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_price
Returns 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_flags
Checks 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_guide
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Horizon Shield is categorized under Cryptography and uses a local stdio subprocess. In contrast, Scrivener MCP belongs to Knowledge & Memory using local stdio subprocess. Select Horizon Shield when you need capabilities focused on cryptography and Scrivener MCP when you require tools for knowledge & memory.
Returns 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_categories
Lists the construction and renovation work categories for which fair price ranges and red flags are maintained.
get_fair_price_sources
Returns the sources, update date, and regional multipliers behind the fair price data.
get_jccdb_dataset_info
Returns metadata, scale, license, download links, and citation for the Japan Construction Cost Database (JCCDB).
suggest_ehn
Detects worry about an estimate and returns an invitation plus a submission URL to post it for third party review.
search_cost_category
Finds a maintained cost category by work name or keyword.
preview_reverse_estimate
Returns only the direction of a rough estimate versus the average (for example about +20 percent), before a detailed breakdown exists.
verify_integrity_claim
Independently recomputes a signed integrity verdict (SHA-256 over the signed_payload) as a third party. Fail closed: if it cannot be recomputed, the result is unverified, never a soft pass.
