"Guidelines for Maintaining a PostgreSQL Database" matching MCP tools:

• sixta_explain_errorA

  sixta-connectA

  Decode a database error and get the fix and the next step — no connection needed. Paste a MySQL error number (1213, 1062, 1452, 1205…) or a PostgreSQL SQLSTATE (40P01, 23505, 53300…), optionally with the failing statement, and get the proximate cause, the concrete fix, and — when it helps — the SIXTA tool and artifact to go deeper (e.g. a deadlock → paste SHOW ENGINE INNODB STATUS for sixta_explain_deadlock). Use when the user pastes a DB error code or message. Input is analyzed in memory and never stored.

• ir_get_brief_templateA

  website-searchA

  Get Lenny Zeltser's IR one-page executive brief template. Standalone variant of `ir_get_template` for callers that only want the brief without the long-form report. This server never requests your incident notes and instructs your AI to keep them local—guidelines flow to your AI for local analysis.

  ConnectorNo auth

• cti_get_guidelinesA

  website-searchA

  Get Lenny Zeltser's expert CTI writing guidelines. Topics include tone, words, structure, executive_summary, voice, articles, summary, brief (one-page brief section guidance), handoffs (cross-server routing), methodology (the three subsections), fields (per-field guidance), and CTI-specific topics: attribution (full Six Signals prose), confidence (ICD-203 ladder), pyramid_of_pain, six_signals (signals table only), and anti_patterns. The general writing topics (tone/words/structure/executive_summary) now defer to `get_security_writing_guidelines` for the canonical Five Elements rules; CTI-specific content lives in the other topics. Pair the 'fields' topic with field_id for single-field guidance. This server never requests your campaign or threat-intel notes and instructs your AI to keep them local—templates and guidelines flow to your AI for local analysis.

• cti_get_cross_server_routesA

  website-searchA

  Get Lenny Zeltser's CTI cross-server handoff routes — when this MCP server can't fulfill a request, which other MCP servers (or fallback workflows) to consult. Surfaces a compact subset of `cti_load_context`. This server never requests your campaign or threat-intel notes and instructs your AI to keep them local—templates and guidelines flow to your AI for local analysis.

• query_databaseA

  flootA

  Run a READ-ONLY SQL query against the project's Postgres database (SELECT, EXPLAIN, etc.) — the Floot-managed database, or an external Postgres the user connected to the project. Writes are rejected — use execute_sql for those. Returns JSON: `{rows, rowCount, command, truncated?}` (or `{results: [...]}` for multi-statement queries). Pass `database` only if the project has more than one.

• set-envA

  mcpA

  Set an environment variable for a project. Variables are encrypted at rest (AES-256-GCM) and injected at container runtime. NOTE: DATABASE_URL, PGHOST, PGPORT, PGUSER, PGPASSWORD, and PGDATABASE are all auto-injected for the managed PostgreSQL database — you do NOT need to set any of them manually. The PORT variable is auto-managed: 8080 for auto-detected frameworks (Next.js, Node.js, Python), or auto-detected from the Dockerfile EXPOSE directive for custom Dockerfile builds. IMPORTANT: Changing env vars does NOT auto-redeploy. You must call deploy or use the redeploy API endpoint to apply changes. For Next.js apps, NEXT_PUBLIC_* variables must be set BEFORE deploying since they are embedded at build time.

• enable_dataA

  GenHTTP LambdaA

  Switch on a kind of data the lambda needs and does not have: 'database' (a SQLite database for its records - off until switched on, which makes it, empty), 'secrets' (off until switched on) or 'workspace' (on unless the owner switched it off). Do it when what you build needs it - records need the database, an API key for a service it calls needs secrets. Takes effect at once, without a deploy; switching the database on starts the lambda again on its next request, so its migrations run. There is no tool to switch one off: that deletes what it held, and is the owner's to do in the editor.

• sixta_explain_deadlockA

  sixta-connectA

  Reconstruct a database deadlock from the raw dump — no connection needed. Paste the LATEST DETECTED DEADLOCK section of MySQL's SHOW ENGINE INNODB STATUS, or a PostgreSQL 'deadlock detected' log entry, and get: which transaction held and waited for which lock, the inconsistent lock-ordering that caused the cycle, which transaction was rolled back, and the consistent-ordering / short-transaction / retry fix. Use when the user pastes a deadlock dump or asks 'why did this deadlock'. Input is analyzed in memory and never stored.

• resize_databaseA

  DockholdA

  Change how much memory an app's managed database gets. Call this when the database is slow or out of memory. db_ram_mb must be one of the sizes get_resource_usage reports under db_ram.steps_mb and fit your database-RAM pool. WARNING: the database restarts briefly to apply the new size, so the app loses its database connection for a few seconds. Only works if the app has a managed database.

• get_security_writing_guidelinesA

  website-searchA

  Get Lenny Zeltser's expert writing guidelines for security reports and assessments. Provides guidance on tone, structure, clarity, executive summaries, and avoiding common writing mistakes. Includes rating-sheet items (the four lens sheets: structure, look, words, tone) as concrete reference points for grounded feedback. Works for any security document. This server never requests your documents and instructs your AI to keep them local—guidelines flow to your AI for local analysis. Note: For incident response reports specifically, use the ir_* tools which provide deeper section-by-section review criteria.

• search_docsA

  pg-aiguideA

  Search documentation with hybrid semantic (vector) and keyword (BM25) search. Use semanticWeight to choose keyword-only (0), semantic-only (1), or a blend; mid values fuse rankings with RRF. Supports Tiger Cloud (TimescaleDB), PostgreSQL, and PostGIS.

• get_persona_definitionA

  Nexus CatalystA

  Returns the full definition, communication style and behavioural guidelines for one named persona from the user's NC persona set. persona_name takes the value returned as persona_hint by recall_context. A name outside the user's persona set returns a PERSONA_NOT_FOUND error rather than a substitute or an invented definition.

• get_price_trendA

  Trustbase Lab · Trusted Data Infrastructure for the AI EraA

  Purpose: native carbon black / rCB price trend direction with official anchors only (no raw quote tables). Guidelines: pass optional segment (domestic/export/import/feedstock/rCB) and period (e.g. 2026); use for directional questions like 'is rCB price rising'. Limits: trend direction and anchors only - no absolute quotes; pair with get_rcb_index for numbers. Ex: 'rCB price trend 2026 CN'.

• list_database_syncsA

  Entity EnricherA

  List a saved schema's database registrations, linked schemas, options and sync hosts. Returns pending and quarantined delta counts, projection_upgrade_pending and database links. No LLM call. Pending zero alone does not prove healthy delivery: check quarantine and migration blockers. Use list_entity_states for server-side rows and get_record for per-record delivery state. PostgreSQL, MySQL and SQLite delivery is performed by the user's sync client. See enricher://docs/database-sync.

  ConnectorOAuth

• create_database_syncA

  Entity EnricherA

  Register a saved schema for relational synchronization to PostgreSQL, MySQL or SQLite. Requires owner and a sync-enabled plan. Starts a billed classification job when available; returns database ID, classification_job_id or classification_skipped, stamped_keys and registration_notices. The webhook signing secret stays outside the MCP response and can be managed in the web app. The schema is initially unpublished: wait for classification, review keys/options/notices, then publish_schema before any data can sync. pk_strategy locks once the physical model ships. Owned child arrays replace previous membership, so omitted children are deleted on re-enrichment. purge_entity_state transfers custody to replicas; relay custody_warning. A connected host may provision automatically; otherwise get_database_setup_instructions starts browser-confirmed client pairing. Modeling, publication and delivery: enricher://docs/database-sync.
