• validate_formula

  Dock

  Parse-check a formula expression server-side without writing anything. Returns { ok, error?, rewrittenFormula?, referencedFunctions, unknownFunctions }. Use BEFORE update_row / create_row when the formula references functions or syntax you're not 100% sure of: a `=SUMIFS(...)` with the wrong arg order or a misspelled `=AVERAG(...)` will round-trip into the cell as a stored carrier with no value, and the user will see #NAME? or #VALUE? on next view. Catch it here. `unknownFunctions` flags any identifier that isn't in the Dock Sheets catalog (including likely typos); `referencedFunctions` lists the canonical post-alias names the engine will see. Cheap, public, no auth, no workspace context needed.

• cross_db_query

  ThinAir Data

  ⚠️ SQL MUST BE VALID IN EVERY DIALECT YOU TARGET — stick to ANSI-ish SELECT syntax when mixing pg/mysql/mssql. `SELECT TOP 10` (mssql) or `LIMIT` (others) will fail on the wrong side. Run the same query across 2-4 connections in parallel; returns per-connection rows + errors for diffing. Canonical use cases: regional compare (`['mssql-reporting-us', 'mssql-reporting-eu']`), cross-dialect sync check (`['prod-postgres-fleet', 'prod-mysql-app']`), 3-env drift, 4-region compare. Resolve every connection name via `list_connections` first; tool fails per-connection on unknown names. ARCHITECT-tier cap: 4 connections; https://www.thinair.co/ for unlimited. [ARCHITECT tier]

• chart_instructions

  Autario Data Analytics Platform

  Get the Builder spec schema reference. Returns chart_type enum, required/optional fields per type, palette options, axis-override shape, annotation format, and concrete examples. Call this ONCE at session-start; the spec it returns is the input shape for create_chart_from_spec. Cheaper and clearer than guessing Plotly JSON syntax.

• generate_diagram

  ALM X++ MCP Server

  WHEN: generating a visual diagram of D365 table relationships or security chains. Triggers: 'generate diagram', 'diagramme', 'visualize', 'schéma', 'ER diagram', 'entity-relationship', 'relation diagram', 'security diagram', 'show connections'. Generate visual Mermaid diagrams from D365 F&O knowledge base data. Diagrams render directly in Copilot Chat, Cursor, Claude, and markdown viewers. Types: 'er' (entity-relationship diagram for a table and its relations), 'security' (security chain: Role->Duty->Privilege->EntryPoints -- use when you need a VISUAL Mermaid diagram; for the structured text chain with tables of duties/privileges/entry-points use `trace_security_chain` instead). Note: 'flow' (execution flowchart) is disabled -- static call trees are misleading in D365 due to CoC and event handlers.

• socrata_get_dataset

  socrata-mcp-server

  Fetch full metadata and column schema for a Socrata dataset by ID. Returns field names, data types, descriptions, row count, and licensing. Always call this before writing a socrata_query_dataset — the column types determine correct WHERE clause syntax: Number columns accept bare literals (year=2023) while Text columns require single-quoted strings (year='2023').

  Connector

• cwe_lookup

  ContrastAPI

  Look up MITRE CWE (Common Weakness Enumeration) catalog record from research view 1000. Default response is SLIM (first 3 mitigations, first 3 examples; extended_description is null) — pass include='full' for the verbose record (full mitigations + examples lists, populated extended_description). Returns description, abstract type (Pillar/Class/Base/Variant/Compound), status (Stable/Draft/Incomplete/Deprecated), exploit likelihood, recommended mitigations, observed example CVEs, parent_cwe (walk up the hierarchy), child_cwes (drill down to more specific weaknesses), and cve_count (LOWER BOUND — counts only CVEs whose primary CWE matches; CVEs with multiple CWEs may not be counted). Use after cve_lookup or kev_detail to understand the underlying weakness category; chain with cve_search(cwe_id=...) to enumerate all matching CVEs. Returns 404 when the CWE is not in research view 1000. Free: 30/hr, Pro: 500/hr. Returns {cwe_id, name, description, extended_description (null on slim, populated on include='full'), abstract_type, status, likelihood, mitigations (first 3 by default), total_mitigations, examples (first 3 by default), total_examples, parent_cwe, child_cwes, cve_count, updated_at, verdict, next_calls}.

• orcid_search_researchers

  orcid-mcp-server

  Search the ORCID registry using structured field parameters or raw Solr syntax. All provided structured params are ANDed together. The `query` field appends raw Solr syntax to the generated clause. Returns ORCID iDs with inline name and institution data — no follow-up profile fetches needed for basic disambiguation. For ranked disambiguation of an ambiguous author name, use orcid_resolve_researcher instead. The ORCID Public API caps results at 10,000 — use pagination for large result sets.

• asterwise_get_dream_symbols

  Asterwise

  Returns dream symbols from the database with dual-tradition interpretation: Jungian/Western psychological analysis and traditional Vedic dream-symbol meaning. 500 symbols across 8 categories. Optionally filter by category. SECTION: WHAT THIS TOOL COVERS Each symbol includes: Jungian meaning and archetype (Shadow, Self, Anima, Animus, Great Mother, Wise Old Man, Hero, Trickster, Persona), Vedic dream meaning with Shubha/Ashubha (auspicious/inauspicious) classification, vedic_source tradition label per entry, traditions_agree field flagging where East and West conflict, emotional tone, 2-3 context variants, and related symbol slugs. The traditions_agree='conflict' entries are significant — e.g. Owl (West=wisdom; Vedic=inauspicious death omen), Wedding (West=union; Vedic=inauspicious, medical-astrological tradition warns illness), Gold (West=the Self; Vedic=financial loss warning in medical-astrological tradition). Valid categories: animals, nature, people, places, objects, actions, body, abstract. SECTION: WORKFLOW BEFORE: None — standalone. AFTER: asterwise_get_dream_symbol — get full detail for a specific symbol. SECTION: INPUT CONTRACT category (optional): One of animals, nature, people, places, objects, actions, body, abstract. Omit for all 500 symbols. SECTION: OUTPUT CONTRACT data.total (int) data.category_filter (string or null) data.symbols[] — each: slug (string) name (string) category (string) jungian_meaning (string) jungian_archetype (string) vedic_meaning (string) vedic_auspicious (bool or null — null = mixed/context-dependent) vedic_source (string) traditions_agree (string — 'agree'|'conflict'|'partial') emotional_tone (string) themes[] (string array — for AI synthesis) context_variants[] — { context (string), meaning (string) } related_symbols[] (string array of slugs) SECTION: RESPONSE FORMAT response_format=json — symbol array. response_format=markdown — formatted catalogue. Both return identical data. SECTION: COMPUTE CLASS FAST_LOOKUP — static database. SECTION: ERROR CONTRACT INVALID_PARAMS (upstream): Invalid category → 422. INTERNAL_ERROR: Any upstream API failure → MCP INTERNAL_ERROR SECTION: DO NOT CONFUSE WITH asterwise_get_dream_symbol — single symbol detail by name.

• baselight_sdk_query_execute

  Baselight

  Execute a SQL query on Baselight and wait for results (up to 1 minute). The query executes and returns the first 100 rows upon completion, or info about a pending query that needs more time. Use DuckDB syntax only, table format "@username.dataset.table" (double-quoted), SELECT queries only (no DDL/DML), no semicolon terminators, use LIMIT not TOP. If query is still PENDING, use `sdk-get-results` to continue polling. If totalResults > returned rows, use `sdk-get-results` with offset to paginate.

• gbif_get_species_classification

  gbif-mcp-server

  Return the complete parent chain for a taxon — from kingdom (or domain) down to the taxon itself — as an ordered array. Each entry has its rank, canonical name, and taxon key. The array is returned root-first (kingdom → phylum → class → … → parent of given taxon). Useful for building taxonomic trees or understanding placement without navigating the backbone level-by-level.

  openlibrary-mcp-server

  Fetch a work by Open Library Work ID (OL…W). Returns title, description, subjects, cover IDs, and linked author IDs for follow-up lookups. Works represent the abstract book concept independent of any specific edition. Note: author names are not included — use openlibrary_get_author or openlibrary_search_books for names.

  Connector

• getLatestPapers

  qubitsok — Quantum Computing Jobs, Papers & Researchers

  Get today's quantum computing papers from arXiv — no parameters needed. Use when the user asks "what's new in quantum computing?" or wants a daily paper briefing. Returns the most recent day's papers with title, authors, date, AI-generated hook (one-line summary), and tags. For date-range or topic-filtered search, use searchPapers instead. Use getPaperDetails for full abstract and analysis of a specific paper.

• code_get_file

  searchcode

  Get code from a remote public git repository — either a specific function/class by name, a line range, or a full file. PREFERRED WORKFLOW: When search results or findings have already identified a specific function, method, or class, use symbol_name to extract just that declaration. This avoids fetching entire files and keeps context focused. Only fetch full files when you need a broad understanding of a file you haven't seen before. For supported languages (Go, Python, TypeScript, JavaScript, Java, C, C++, C#, Kotlin, Swift, Rust) the response includes a symbols list of declarations with line ranges. This is not a first-call tool — use code_analyze or code_search first to identify targets, then extract precisely what you need.
