Senzing

Get 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 to the server. Typical workspace_dir values: Linux `/tmp` or `~/sz-workspace`; macOS `~/sz-workspace`; sandboxed envs: explicit path under home (do NOT assume /tmp exists).

Returns 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_dir` (the mapping workflow's) so `dest` matches the workflow's paths; calling with neither filename returns the list of available resources (it does not fail). Available: sz_json_analyzer.py, sz_schema_generator.py, sz_verbatim_check.py, sz_routing_report.py, senzing_entity_specification.md, senzing_mapping_examples.md, identifier_crosswalk.json mapping_workflow and analyze_record already return each resource's `fetch` command — you do not need this tool to run them. If a previously-known fetch instruction stops working, call this tool again to obtain the current one.

Explain 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 working SOURCE CODE examples from 52 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 (.py, .java, .cs, .rs, .ts, .js) and READMEs — NOT build/data files. For sample data, use get_sample_data. Covers Python, Java, C# (official SDKs) plus Rust and TypeScript/Node.js (community-maintained wrappers, not official) SDK patterns: initialization, ingestion, search, redo, configuration, message queues, REST APIs. Use max_lines to limit large files. File retrieval returns the file's location instead of its content: follow the returned `resources` / `access_steps` exactly as given.

Generate 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. Languages: python, java, csharp (official V4 SDKs); rust, typescript (community-maintained wrappers, not official). Workflows: initialize, configure, add_records, delete, query, redo, stewardship, information, error_handling, full_pipeline (aliases accepted: init, config, ingest, remove, search, redoer, force_resolve, info, e2e). V3 supports Python only. Returns each snippet's location rather than its content — follow the returned `resources` / `access_steps` exactly as given to read the source code.

Get 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, deployment, troubleshooting, database, configuration, data mapping, etc.) — use it to triage which Senzing MCP tool to call before going to external sources

Get 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 explicit pagination or the string "random" (the default when omitted) for a random starting position. IMPORTANT: The three CORD datasets ('las-vegas', 'london', 'moscow') are REAL data (not synthetic) — historical snapshots for evaluation only, not operational use. Always inform the user of this. This does NOT apply to 'truthset', which is Senzing's own synthetic demo truth set (github.com/Senzing/truth-sets) — do not describe those records as real people's data. Each response's citation carries the provenance for the dataset actually returned; follow it rather than this summary. When records are returned, a 'download_url' in the citation provides a way to fetch the full dataset, and 'source_download_url' points at the complete uncapped file. Always present the fetch instruction to the user exactly as given. Downloading the dataset TO DISK is expected and encouraged whenever the user wants the data — run the returned download instruction in a shell (a URL to fetch with curl/wget, or a local command) to write it to a file, and work from that file. What you must NOT do is pull the dataset INTO THE CONVERSATION: never echo, cat, paste or summarise raw records back into context, because these files run to hundreds of thousands of records. The inline records above are a small preview of the data shape, not the delivery mechanism. (An earlier wording of this line said only 'Do NOT download it yourself', which was read as a blanket ban on fetching and left users downloading files by hand.) If a previously-known download instruction stops working, call this tool again to obtain the c

Get 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 for — so looking up a method's flags also tells you what it takes. Topics: 'parameters' (aliases: functions, methods, classes, api, signatures, args) returns argument types per binding — the same method differs by binding in BOTH name and argument types: Python find_network_by_entity_id takes List[int], Java findNetwork takes SzEntityIds, C# FindNetwork takes ISet<long>, Rust takes &[EntityId], TypeScript findNetwork takes Array<number> and renames buildOutDegrees to buildOutDegree; 'flags' (all V4 engine flags and the methods they apply to; with a method filter: one line per applicable flag — NAME (default) — meaning, composites as NAME = A|B|C — under group headers, most specific to the method first, under 5k chars); 'flag_details' (the full definitions and response paths for a method filter); 'response_schemas' (JSON response structure per method); 'migration' (V3→V4 breaking changes, renames, flag changes); 'all'. 'filter' accepts any spelling — 'get entity', 'get_entity', and 'getEntity' all resolve. Pass 'language' (python/java/csharp/rust/typescript) to narrow to your binding; cross-binding divergence warnings are still included so you never translate a call between bindings by mistake

Map source data to Senzing JSON through a guided 8-step workflow. Use this INSTEAD of hand-coding Senzing JSON. Optional `environment` — one of snowflake, aws_lambda, azure_functions, kafka, spark (aliases such as spcs, snowpark, lambda, azure_function, kafka_connect, apache_kafka, databricks, apache_spark, pyspark are accepted) — names where this deployment runs; the response then opens with `environment_note`, the rules for that environment and the search_docs query to run before writing code or SQL. For mapping_workflow the note is on the start response only; dotted DB.SCHEMA.TABLE source labels (bare or with a data-file extension) infer environment=snowflake. 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") — a writable directory where scripts, reference docs, mapper code, and outputs are saved. Do NOT assume /tmp exists (some environments like Kiro do not provide it). The call needs both arguments present; it does NOT need the file to exist. OPTIONAL on start: `output_path` — the output file the USER ASKED FOR, if any (a .jsonl path; a directory ending in / for one <schema_name>.jsonl per schema; or a per-schema map {"<schema_name>": "<path>.jsonl"}). Omit it for the default <workspace_dir>/<name>_output.jsonl. Start arguments are accepted at the top level or inside `payload`. NO READABLE FILE, NO SHELL — START ANYWAY. If the user only DESCRIBED their columns, or you have no shell to run the profiler, step 1 accepts a `profile_summary` you write yourself: field_count from their column list, record_count as they stated it or 0 (zero means 'not measured' and is expected — it is not fabrication). An unreadable source file is NOT a reason to hand-code a mapping instead. Actions: start, advance, back, status, reset. Core steps 1-

Guided reporting and visualization for Senzing entity resolution results. Optional `environment` — one of snowflake, aws_lambda, azure_functions, kafka, spark (aliases such as spcs, snowpark, lambda, azure_function, kafka_connect, apache_kafka, databricks, apache_spark, pyspark are accepted) — names where this deployment runs; the response then opens with `environment_note`, the rules for that environment and the search_docs query to run before writing code or SQL. 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/how SDK patterns), data_mart (schema + incremental update patterns), dashboard (visualization concepts + data sources), graph (network export patterns), quality (precision/recall/F1, split/merge detection, review queues, sampling strategies), evaluation (4-point ER evaluation framework with evidence requirements, export iteration stats methodology, MATCH_LEVEL_CODE reference). Returns decision trees when language/scale not specified.

Install 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). Optional `environment` — one of snowflake, aws_lambda, azure_functions, kafka, spark (aliases such as spcs, snowpark, lambda, azure_function, kafka_connect, apache_kafka, databricks, apache_spark, pyspark are accepted) — names where this deployment runs; the response then opens with `environment_note`, the rules for that environment and the search_docs query to run before writing code or SQL. 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 install and this server runs on the install host itself, it detects the platform from that host's os-release. Languages: 5 (Python, Java, C#, Rust, TypeScript). Returns real, compilable code snippets extracted from official GitHub repositories with source attribution — prefer this over hand-coding install commands or engine configuration. When this server carries the SDK packages for the chosen platform (.deb for linux_apt, .rpm for linux_yum, the macOS packages for macos_arm, and the .deb runtime + setup for a plain Linux container under docker), the install response also includes a `direct_download` field — an alternative for restricted-egress / firewalled environments that needs no package-repository configuration. Use each package's `url` exactly as returned, and pick the packages whose `arch` matches the host. Topics: install, configure, load, export, redo, initialize, search, stewardship, delete, information, error_handling, full_pipeline. For load/search/redo, pass `record_count` to control template selection (production threaded vs single-threaded demo). Export redirects to reporting_guide. If a previously-known download instruction stops working, call this tool again to obtain

Full-text BM25 search across all indexed Senzing documentation (~13.5k chunks). Returns ranked results with excerpts. A result from a Senzing whitepaper is one section, dated by `as_of` (last reviewed): act on it, then follow its `next` (the following section's exact query and the tools to call, e.g. sdk_guide with environment). 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 question. Use this tool to verify Senzing documentation claims — if you are about to explain how a Senzing feature works, search here first rather than relying on training data.
