Siftable MCP server

Siftable MCP Server

A Model Context Protocol server that exposes Siftable tools to IDE clients like Cursor, Claude Desktop, and VS Code.

ExecuFunction 0.4.0.0 hosted compatibility

The npm package is 1.3.0; the hosted and source projection profile is 1.34.0. Projection 1.34.0 standardizes bounded collection receipts, publishes dataset aggregate semantics, and distinguishes OAuth connections that must reconnect from sessions that can widen authorization in place. Projection 1.33.0 recognizes natural-language source-search intent and returns the retired capability card with local recovery rather than routing the request to curated code memories. Projection 1.32.0 added an explicit no_matches discovery outcome, rejects generic-operation and weak-prefix-only capability matches, preserves canonical compound-intent matches, and captures HTTP status classes in failure receipts. Projection 1.31.0 added governed lead-discovery scope requirements. Projection 1.29.0 added managed work-lease sessions for hosted clients while keeping claim tokens server-side. Projection 1.28.0 added four governed lead-discovery tools and five app-equivalent person/organization enrichment tools.

Lead discovery is disabled by default. When enabled, it requires separately granted leaddiscovery:read or leaddiscovery:write scopes; mcp: does not imply either scope. Hosted baseline catalogs therefore omit company search until requestcapability approval and a catalog refresh expose the hosted-capable tool. A company search is bounded to one paid Crustdata request, shows a maximum charge before dispatch, settles the actual provider credits, and saves results only as review candidates. Canonical CRM records are created through leaddiscoveryimportplancreate followed by the existing crmimportplanapprove and crmimportplanapply review gates.

Person enrichment returns stored profile and fact proposals. Apply accepts only proposal field names and fact IDs rehydrated from the completed run; it does not accept free-form replacements and is not retry-safe. Organization enrichment remains the app's paid preview-only flow and cannot apply canonical CRM changes.

1.3.0 compatibility note

Version 1.3.0 publishes sift.dataset.query.v2, versioned aggregate receipts, uniform work-item collection metadata, and the reconnect_required capability state. Consumers that validate the previous dataset-query receipt should select behavior by schemaId.

1.2.42 compatibility note

Version 1.2.42 closes the publication-readiness audit. Natural-language source search discovery returns the canonical retired/local-only recovery card, while curated code-memory discovery remains distinct. The hosted setup guide now gives exact ChatGPT and Codex configuration steps.

1.2.41 compatibility note

Version 1.2.41 closes two hosted audit failures. Dataset routes reject malformed dataset UUIDs at the HTTP boundary, and MCP receipts preserve the resulting 400 as badrequest. findcapability now requires a direct domain signal plus an aligned operation; unrelated intent returns queryOutcome: no_matches with empty capability lanes and rephrase guidance. Exact tool names, removed-tool cards, and virtual orientation tools bypass semantic rejection.

1.2.40 compatibility note

Version 1.2.40 addresses the third round of live agent QA (the 2026-08-22 hosted audit).
