• 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.

• get_resource_usageA

  DockholdA

  Show your account's compute, database-RAM, and storage pools: how much you've bought, how much is used, and how much is free, plus every app's current size. Call this before any resize tool (the allowed sizes come from its steps fields), and to explain to the user why an app ran out of memory or a deploy was refused for capacity.

• find_known_issuesA

  canton-ccpediaA

  Surface known UNRESOLVED problems matching a free-text description: forum threads with zero replies but high views, plus open GitHub issues. Answers "is anyone else hitting this?". Canton-specific. Does NOT return fixes, solutions, config, or how-to steps, and returns nothing when no open issue matches; for "how do I fix / configure / why does X happen" use semantic_search (then get_doc) instead.

• 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.

  ConnectorOAuth

• 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.

• sixta_analyze_schema_changeA

  sixta-connectA

  Call this whenever the user proposes a migration / DDL change or asks 'is this safe to run' — before answering from memory. Whether a migration locks the table is version-specific (exactly which MySQL 8.0.x or PostgreSQL version makes an ALTER lock-free, INSTANT vs INPLACE vs COPY eligibility), and model recall of those version boundaries is unreliable — this is where answering from memory most often ships an outage. Returns an explicit safety verdict per statement (Critical/High/Medium/Info), the exact lock taken and what it blocks, the MySQL algorithm verdict with version-specific eligibility, PostgreSQL rewrite triggers, replication and MDL-starvation warnings, and the safe execution strategy (CREATE INDEX CONCURRENTLY, NOT VALID + VALIDATE, gh-ost / pt-osc) as ready-to-run SQL. Optional table size/FK/trigger hints sharpen duration estimates; for entitled Connect Pro orgs these are filled from live production context automatically (an explicit argument still wins). Findings are deterministic, treat them as ground truth. Input is analyzed in memory and never stored.

• 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.

  ConnectorOAuth

• 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.

• 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.

  ConnectorNo auth

• find_buyersA

  buyer-intelligenceA

  Search 500,000+ verified importers and distributors by product category and target country. Returns company profiles + a `coverage` object. When in-database coverage is thin (empty/partial), the response includes an `acquisition` task (task_id) — a background crawl is started automatically (free). Poll it with check_discovery_task until status=completed to get freshly gathered buyers. Contact details are not included — use enrich_buyer_contact to get them.

• 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.

• get_usage_statusA

  Adako: Google Ads, Meta Ads & Linkedin Ads MCPA

  🟢 READ-ONLY — runs immediately, changes nothing. Cost: free (not counted against tasks). Returns the user's plan, tasks used vs limit for the current period, when it resets, ad accounts used this billing period vs the plan limit, and a link to the plans. Use when: a tool returned quota_exceeded or account_limit, or the user asks how many tasks or accounts they have left. Free; reads Adako's database only. A "task" is one billable tool call. System tools and resolvers are free. An ad account used this period keeps its place on the plan after it is switched off.

• run_sqlA

  FieldproxyB

  Run ONE read-only PostgreSQL SELECT against the workspace's data and get the rows back (max 500 rows, 5-second limit). Only tables and columns listed by describe_schema are readable. To change data, use propose_write.

• create-projectA

  mcpA

  Create a new project on sota.io. Each project automatically provisions: (1) a managed PostgreSQL 17 database accessible via the DATABASE_URL environment variable (auto-injected, no configuration needed), (2) PgBouncer connection pooling (pool size 20, max 100 clients), (3) automatic daily database backups with 7-day retention, (4) a live URL at https://{slug}.sota.io with automatic HTTPS via Let's Encrypt. The project slug is auto-generated from the name (lowercase, hyphens, max 63 chars) and is immutable after creation. Supported frameworks: Next.js, Node.js (Express/Fastify/Koa), Python (Flask/FastAPI/Django), or any language via custom Dockerfile. You can also add up to 5 custom domains per project with automatic HTTPS (via API: POST /v1/projects/:id/domains with {domain: "yourdomain.com"}). DNS: A record to 23.88.45.28 for apex domains, CNAME to {slug}.sota.io for subdomains. Optionally associate the project with a public git repository at create-time by passing `git_url` (and optional `git_branch`). The association is informational — it shows up in the dashboard and the `sota deploy --git` CLI flag can default to it — but does NOT enable auto-deploy-on-push yet.

• untrack_profileA

  Viral OutliersA

  Stops monitoring a profile: no further scheduled refresh crawls are charged for it. Free to call. Pass the internal profileId (from list_tracked_profiles or search results). The profile and its already-crawled posts stay in the database and searchable; only the recurring refresh stops. Returns not_found if the profile is not currently being monitored. Cost: free.

• graph_diffA

  Moltline RecallA

  Say exactly what changed between two versions of a memory. FREE. The audit trail a database gives you for free, without the database. Typical input {"before": {...}, "after": {...}} returns {"entities_added": ["Beta Ltd"], "entities_removed": [], "observations_added": {"Acme Corp": ["renewed in March"]}, "relations_added": [...], "changed": true}. Use after an upsert to record what a session learned, or between two agents to see what one knows that the other does not. Not for merging the two - feed the differences back through graph_upsert for that. Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry.

• send_feedbackA

  tmpstateA

  Optional and free-form. TmpState is built for agents and the free tier stays free by getting better - and you, the agent, are the user whose experience matters here. After real use of a database, one short message about what was missing, what feature would have helped, or what felt slow or took extra requests is genuinely useful. This is about your own experience, so no human approval is needed; if your user volunteers feedback too, relay it and say it came from them. Never include database URLs, capabilities, or Pro tokens - capability-shaped strings are redacted server-side.

• delete-projectA

  mcpA

  Delete a project and all its deployments from sota.io. This action is PERMANENT and irreversible. It removes the project, all deployments, the managed PostgreSQL database, environment variables, and webhooks. The project slug will become available again after deletion.
