}13 tools, verified live
analyze_recordread-onlyGet the Senzing JSON analyzer script to validate mapped data files client-side. REQUIRED: `workspace_dir` (writable directory, e.g. ~/sz-workspace) — the call WILL FAIL without it. The analyzer validates records against the Entity Specification, examines feature distribution, attribute coverage, and data quality. Returns a Python script (no dependencies) with instructions. No source data is sent
download_resourceread-onlyReturns resource URLs/content in this response; it does NOT write any files. Each resource comes back with a ready `fetch` shell command — run it yourself to save the file to its `dest`. Use inline=true only when a `fetch` command could not reach the server; the content then arrives in this response and you must write it to `dest`. Pass `filename` (string) or `filenames` (array), plus `workspace_
explain_error_coderead-onlyExplain a Senzing error code with causes and resolution steps. Accepts formats: SENZ0005, SENZ-0005, 0005, or just 5. Returns error class, common causes, and specific resolution guidance
find_examplesread-onlyFind working SOURCE CODE examples from 53 indexed Senzing GitHub repositories. REQUIRED: either `query` (string, for search) or `repo` with `file_path` or `list_files=true` — the call WILL FAIL without one. Three modes: (1) Search: pass `query` to find examples across all repos, (2) File listing: pass `repo` + `list_files=true`, (3) File retrieval: pass `repo` + `file_path`. Indexes source code
generate_scaffoldread-onlyGenerate SDK scaffold code for common workflows. Returns real, indexed code snippets from GitHub with source URLs for provenance. Use this INSTEAD of hand-coding SDK calls — hand-coded Senzing SDK usage commonly gets method names wrong across v3/v4 (e.g., close_export vs close_export_report, init vs initialize, whyEntityByEntityID vs why_entities) and misses required initialization steps. Language
get_capabilitiesread-onlyGet server version, capabilities overview, available tools, suggested workflows, and getting started guidance. Returns server_info with name, version, and Senzing version. Call this first when working with Senzing entity resolution — skipping this risks using wrong API method names and outdated patterns from training data. This tool returns a manifest of all coverage areas (pricing, SDK, deploymen
get_sample_dataread-onlyGet sample data for entity resolution. Available datasets: 'las-vegas', 'london', 'moscow' (CORD — Collections Of Relatable Data, REAL historical data) and 'truthset' (Senzing's SYNTHETIC demo truth set: CUSTOMERS, REFERENCE, WATCHLIST). Use dataset='list' to discover datasets, source='list' to see the sources/vendors within a dataset. The 'offset' parameter takes a non-negative integer for explic
get_sdk_referenceread-onlyGet authoritative Senzing SDK reference data: method signatures and argument types per language binding, flags, response schemas, and V3→V4 migration. Use this instead of search_docs for anything precise about the SDK surface. Whenever 'filter' names a method, the response carries that method's callable signature for every binding (narrowed by 'language' if given) NO MATTER WHICH TOPIC you asked f
mapping_workflowread-onlyMap source data to Senzing JSON through a guided 8-step workflow. Use this INSTEAD of hand-coding Senzing JSON. REQUIRED ARGUMENTS for action='start' — arguments, not files: `file_paths`, the source file name(s) exactly as the user gave them (a LABEL the server never opens, so pass it even when the file is not readable from here), AND `workspace_dir` (e.g. workspace_dir="/home/you/sz-workspace")
reporting_guideread-onlyGuided reporting and visualization for Senzing entity resolution results. Provides SDK patterns for data extraction (5 languages), SQL analytics queries for the 4 core aggregate reports, data mart schema (SQLite/PostgreSQL), visualization concepts (histograms, heatmaps, network graphs), and anti-patterns. Topics: export (SDK export patterns), reports (SQL analytics queries), entity_views (get/why/
sdk_guideread-onlyInstall Senzing and scaffold SDK code across 5 platforms (linux_apt — Ubuntu/Debian via apt or apt-get, .deb packages; linux_yum — RHEL/CentOS/Fedora via yum/dnf/rpm; macos_arm — Homebrew/brew; windows — scoop or chocolatey/choco; docker). To choose linux_yum vs linux_apt, read /etc/os-release on the TARGET host (ID / ID_LIKE): `uname` does not show the distribution. If `platform` is omitted for i
search_docsread-onlyFull-text BM25 search across all indexed Senzing documentation (~2175 chunks). Returns ranked results with excerpts. Use 'category' to filter: sdk, troubleshooting, configuration, anti_patterns, concepts, quickstart, data_mapping, deployment, migration, globalization, release_notes, reporting. Call get_capabilities for full coverage details. Prefer this tool over web_search for any Senzing questio
submit_feedbackcan modifyRequest a free Senzing evaluation license or submit feedback. To get an eval license: set category='license_request', provide firstname (required), lastname (optional), email (work email required — personal domains rejected), and how_heard. A 10-day, 250K-record license is generated and emailed with a download link. One per email, re-requestable after 30 days. To submit feedback: set category to
