"How to connect to a database" matching MCP tools:

• x-twitter.connected_accounts

  Vee3

  List X (Twitter) accounts connected to the authenticated Vee3 account for write capabilities. Returns user_id, user_name, display name, avatar URL, and whether each account is the default. Use user_id or user_name on future write calls, or omit both to use the default account. If accounts is empty, the user must connect an X account at https://vee3.io/dashboard/connections before write capabilities work. Agents cannot complete OAuth; ask the user to connect, then call this tool again. Cost = 0 tokens.

• slack_channel_search

  Perspective AI

  List a workspace's Slack channels whose name contains a substring (paged). Reads the indexed channel directory, so it's fast. Read-only — to confirm a specific channel before saving an automation, use slack_channel_resolve. Behavior: - not_connected: Slack isn't connected — connect it via integration_manage (operation "connect") first. - directory_synced: false with an empty result means the directory hasn't been indexed yet — run slack_channel_refresh, then search again. Examples: - `{ "query": "feedback", "limit": 25 }` - `{ }` (list all indexed channels)

• integration_manage

  Perspective AI

  Read-only inspector for workspace integrations. Operations: "list" enumerates the registered providers (currently slackbot, hubspot, gmail, googledocs, notion, confluence, salesforce) and connection status; "connect" returns a setup URL the user opens in a browser to complete OAuth; "search_tools" returns the available action slugs (e.g., SLACKBOT_SEND_MESSAGE, HUBSPOT_SUBMIT_FORM, GMAIL_SEND_EMAIL) for a connected provider. Behavior: - Read-only. Does NOT itself perform OAuth — "connect" just hands a setup URL back so the user can finish the connection in the web app. - Errors when the workspace is not found or you do not have access. - search_tools returns success: false with "No active <provider> connection. Use 'connect' operation first." when the provider is not connected. Limit is 10 tools per search. - Required params per operation: connect needs provider; search_tools needs provider and query. MCP schema validation rejects missing or unrelated operation arguments before execution; the handler retains equivalent errors for non-MCP callers. When to use this tool: - Checking which integrations the workspace has connected before configuring an automation that talks to one of them. - Surfacing the setup URL to the user when they want to connect a provider. - Discovering action slugs to populate provider-backed automations. When NOT to use this tool: - Creating or modifying automations — use automation_create / automation_update after the provider is connected. - Sending a real message to test a provider wiring — create the automation first, then run automation_test. Examples: - List: `{ "operation": "list" }` - Connect: `{ "operation": "connect", "provider": "slackbot" }` - Search: `{ "operation": "search_tools", "provider": "hubspot", "query": "create contact" }`

• explain_architecture

  Zephex

  Maps how files connect across a subsystem — roles and import edges, not file bodies. Ripgrep + import-graph analyzers; detects framework, language, architecture_type. Envelope: focus, summary, hint, data, related_focus, next_calls, meta (meta.cache_hit, meta.tokens_returned, meta.credits, meta.charges_usage). Hosted: 7 credits per success; failures free. Cheapest path: mode overview + concern or seed_files — ~1.5–4k tokens, replaces 10+ blind read_code file opens. Repeat identical calls hit server cache (meta.cache_hit) until force:true. Expensive: mode deep or audit on whole monorepo — use subpath. >10k files auto-degrades to overview. data: entry_points, layer_map, concern_cluster (with concern or seed_files[]), integration_map, auth_flow, dependency_graph; deep adds request_flows + Mermaid; audit adds anti_patterns + health_score. dimension_confidence per slice; warnings on low confidence. focus: api|auth|integrations|database|security|data_flow|error_handling|full. Pass concern (any label) or seed_files[] (1–20 from find_code). subpath scopes monorepos. Call BEFORE cross-cutting edits — how a feature spans modules, where to patch. Do NOT for stack (get_project_context), search (find_code), bodies (read_code), tests, packages, live URL. After: next_calls → read_code outline on hub files. Read-only.

• get_related_terms

  Arco Lexicon

  Returns the full relationship graph for a given Lexicon term. Each related term includes: the related term's slug and title, a plain-English description of the relationship, a direction (inbound or outbound), and a canonical URL. Read-only. No LLM calls. Use this when you need to understand how terms connect — use lookup_term instead when you need a definition.

• check_balance

  PikaSim

  Returns the prepaid spending balance of the connected PikaSim agent wallet, in USD. Read-only; makes no changes. Call this before purchase_esim or purchase_phone_plan to confirm sufficient funds, or any time you need the current balance. Requires a connected agent wallet (OAuth or ak_live_ key). If no wallet is connected, the result explains how to connect one.

  Connector

• connect_onboard

  bookstore4agents

  Start (or resume) Stripe Connect onboarding so this account can RECEIVE author royalties. Returns a one-time onboarding_url the human author must open in a browser to complete KYC. Required before a book can be published: an author with no payouts-enabled Connect account can save drafts but their books stay in draft until onboarding finishes. Payouts stay disabled until Stripe verifies the details — poll connect_status afterward.

  Connector

• request_payout

  bookstore4agents

  Immediately withdraw this account's FULL pending royalty balance via Stripe Connect, bypassing the monthly batch and its minimum threshold. This MOVES MONEY and the recipient bears the transfer fee. This is a TERMINAL ACTION: only call it when the author has EXPLICITLY asked to withdraw / cash out now. Do NOT call it just to check the balance — use payout_balance for that. Fails if Connect onboarding isn't complete or there's no pending balance.

• connect_m365_account

  local-mcp

  Connect your Microsoft 365 account. Call once to get a login code, then call again after you've authenticated at microsoft.com/devicelogin to confirm the connection.

• delete_collection

  tmpstate

  Delete every document in a collection at once (useful to re-seed). Irreversible. To destroy the entire database, use delete_database instead.

  Connector

• list_meta_pages

  Hermoso

  List the Facebook Pages (with any linked Instagram business account) and ad accounts on the connected Meta account — use before post_to_meta / create_meta_campaign to pick the target. Requires the user to have connected Meta (Settings ▸ Connectors ▸ Meta); returns a connect hint if not.

• credawait

  InsideOut (Riley)

  Wait for the user to securely connect their cloud account and subscribe to Luther Systems. Polls until credentials appear on the session. 🎯 USE THIS TOOL WHEN: tfdeploy returns an 'auth_required', 'no_credentials', or 'credentials_expired' error. The user needs to visit the connect URL to: 1. Connect their cloud credentials (AWS or GCP) 2. Sign up and subscribe to a Luther Systems plan (required for deployment) This secure connection allows InsideOut to deploy and manage infrastructure in the user's cloud account on their behalf. Credentials are handled securely and only used for deployment and management sessions. WORKFLOW: 1. FIRST: Present the connect URL and explanation to the user (from the tfdeploy error response) 2. THEN: Call this tool to begin polling for credentials 3. The user opens the URL in their browser to subscribe and add credentials 4. When credentials are found, inform the user and call tfdeploy to deploy IMPORTANT: Do NOT call this tool without first showing the connect URL to the user. The user needs to see the URL to complete the process. REQUIRES: session_id from convoopen response (format: sess_v2_...). OPTIONAL: cloud ('aws' or 'gcp'), timeout (integer, seconds to wait, default 300, max 600).

• apiosk_payment_guide

  Apiosk MCP

  Explain how to pay through the Apiosk gateway. Returns a buyer guide (how an agent settles a paid API call over USDC/x402, tailored to the current auth) and a provider guide (how to publish an API and get paid). Pass slug to scope buyer guidance to one listing, or role to pick a side.

• how-to

  Fast.io

  Built-in product help — ask a natural-language "how do I…" question about Fastio and get a grounded, product-aware answer (or a short clarifying question) back in one call. EXPLAIN-ONLY / ADVISORY: it returns GUIDANCE TEXT and performs NO platform action (it will not create shares, move files, or change anything) — read the guidance, then act with the other tools. Answers are grounded in Fastio's own how-to knowledge AND phrased in terms of these MCP tools — they name the concrete `<tool> action="…"` calls to make — so prefer this over guessing endpoints or burning exploratory calls. For Q&A over YOUR uploaded files (RAG) use the `ai` tool instead — `how-to` answers questions about Fastio ITSELF. FREE and requires only an authenticated user (no org, no plan gate, no billing). Call action='describe' for the full action/param reference.

• get_resource_usage

  Dockhold

  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.

  Connector

• resize_database

  Dockhold

  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_stats

  MRC Data — China's Apparel Supply Chain Infrastructure

  Get overall database statistics: total counts of suppliers, fabrics, clusters, and links. USE WHEN user asks: - "how big is your database" / "what's the coverage" / "data overview" - "how many suppliers / fabrics / clusters do you have" - "database size / scale / freshness" - "is the data up to date" - "live counts for MRC data" - "first-time onboarding: 'what can MRC data do for me'" - "数据库多大 / 有多少数据 / 覆盖多少供应商" - "你们的数据规模 / 数据量 / 新鲜度" WORKFLOW: Standalone discovery tool — call this first when a user asks about data scale or freshness. Follow with get_product_categories or get_province_distribution for deeper segment coverage, or with search_suppliers/search_fabrics/search_clusters to drill in. DIFFERENCE from database-overview resource (mrc://overview): This is dynamic (live counts + generated_at). The resource is static (geographic scope, top provinces, data standards). RETURNS: { database, generated_at, tables: { suppliers: { total }, fabrics: { total }, clusters: { total }, supplier_fabrics: { total } }, attribution } EXAMPLES: • User: "How big is the MRC database?" → get_stats({}) • User: "Give me the latest data scale numbers" → get_stats({}) • User: "MRC 数据库有多少供应商和面料" → get_stats({}) ERRORS & SELF-CORRECTION: • All counts 0 → database query failed or D1 binding lost. Retry once after 5 seconds. If still 0, surface a transport error to user. • Rate limit 429 → wait 60 seconds; do not retry immediately. AVOID: Do not call this before every tool — only when user explicitly asks about scale. Do not call to get per-category counts — use get_product_categories. Do not call to get geographic scope metadata — use the database-overview resource (mrc://overview) which is static. NOTE: Only reports verified + partially_verified records. Unverified reserve data is excluded from counts. Source: MRC Data (meacheal.ai). 中文：获取数据库整体统计（供应商总数、面料总数、产业带总数、关联记录数）。动态快照，含生成时间戳。

• connect_account

  Tu Lugar

  THE tool to connect/authorize the user's Tu Lugar account. Call this IMMEDIATELY (without first calling account_status) whenever the user asks to "connect", "authorize", "link", "log in to", or "sign in to" Tu Lugar, or wants to create/manage a listing while not connected — do NOT wait for them to create a listing first. When not connected, it returns a clickable "Connect your Tu Lugar account" link — show that link to the user verbatim and tell them to open it (one click if they are already signed in at tulugar.com; no separate Approve step). After they open it they are connected — they can then ask you again. If already connected, it confirms who they are connected as. account_status only REPORTS status and can never start this.
