Which MCP Server Should You Choose?
S
Choose Sensefold when:
You need dedicated capabilities in the Developer Tools domain.
You prefer remote streaming HTTP/SSE transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Hybrid keyword + semantic search across the whole library. English, Chinese, or mixed queries; matching is cross-lingual. Filters: `tags`, `provenance` (`authored` / `clipped` / `ai_summary` / `ocr` / `any`), `start` + `end` date range, `limit` (default 5, max 50).
list_items
Recent items, newest first. Filters: `start` + `end` (ISO, together), `provenance`, `keyword` (literal AND over full text, not semantic), `limit` (default 10, max 50).
get_item
One item by UUID as Markdown text plus `version`. Windowed: default first 8,000 characters, then `windowStart` = previous `nextStart` (`windowLength` up to 20,000). Chunk mode: `chunk` (ordinal from `chunkRef`) with `chunkRadius` 0–3 neighbours (default 1).
get_quota
The user's plan, remaining credits, and storage.
save_link
Save an HTTP(S) URL (`id` UUID v4 you generate, `url`). Capture and enrichment run asynchronously and spend credits like a save from the app; the response reports `status`, `replayed`, and `consentRequired` / `insufficientCredits` when enrichment did not run.
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).
Sensefold is categorized under Developer Tools and uses a remote streaming HTTP/SSE transport. In contrast, ToughTongue AI belongs to Developer Tools using local stdio subprocess. Select Sensefold when you need capabilities focused on developer tools and ToughTongue AI when you require tools for developer tools.
Save a plain-text or Markdown note (`id` UUID v4, `authoredContent`, optional `hubTitle`). Stored verbatim, never AI-enriched, searchable shortly after.
update_note
Replace the user-authored text layer of any item (`authoredContent`, optional `hubTitle` to rename, `expectedVersion`). For notes that is the note; for clips and articles it overrides the extracted body while the original source stays archived. Revision-backed and undoable.
update_tags
Replace an item's full tag list (`tags`, up to 20, the complete list not a delta; `expectedVersion`). Revision-backed and undoable.
delete_item
Move an item to the recycle bin (`expectedVersion`). The user can restore it. Deleting an already-deleted item succeeds with `alreadyDeleted: true`, so retries are safe.
