Crevio MCP server

• api_executewrite actionFree

  Execute Ruby in a sandboxed VM against the Crevio REST API. Use `api_search` first to find the endpoint and its body fields, then call it here. Chain calls, transform results, return the final expression. ## Available in your code ``` get(path, params = {}) # paths auto-prefixed with /v1, routed in-process post(path, **body) # body as keyword args or a hash — both work patch(path, **body) delete(path) find_endpoints(query) # -> ["METHOD /path — summary", ...] iso8601(offset_seconds = 0) # mruby Time has no strftime/iso8601 ``` Returns the **last expression**; `puts` is side-channel only. Every run answers `{result:, calls:, output:}` — `calls` audits each REST call (`method`, `path`, `status`, plus `error_code`/`param` on failure). When `result` has unexpected nils, read `calls` for a non-2xx. Never project only success fields (`{id: r["id"]}`) — that hides the error from `result`. ## Rules that the schema does not tell you - Params are unwrapped, Stripe-style: fields at the TOP level. `{product: {...}}` is silently dropped by most endpoints. - Associations take the bare resource name and a prefix_id string — `product: "prod_x"`, never `product_id:`. Some required ones never appear in a schema's `properties`. - Courses and content live under `/experiences`, NOT `/products`. - Lists answer `{object: "list", data: [...], has_more}`; single resources answer the object directly. - Connected integrations go through the same REST surface: `post("/connections/<id>/execute", tool: "<tool>", arguments: {...})`, with ids from `get("/connections", search: "<service>")`. - Sandboxed mruby: no `File`, `ENV`, `Net::HTTP`, `Process`. 10s, 10 MB. ## Example — publishing a product (the ordering trap) A product cannot be created active: it needs a price variant first, or the call 422s. ```ruby product = post("/products", name: "...") post("/price_variants", product: product["id"], name: "Standard", amount_type: "fixed", amount: 4900, currency: "usd", billing_type: "one_time") patch("/products/#{product["id"]}", status: "active") ``` API groups: Access, Account, Ads, Analytics, ApiKeys, Approvals, Audio, Billing Portal, BlogCategories, BlogPosts, Bookings, Bots, Broadcasts, Calls, Chapters, CheckoutConfiguration, CheckoutLinks, Checkouts, Connections, Customers, Deployments, Discounts, Domains, Email, Email Suppressions, EventSessions, EventSources, EventTypes, Events, Experiences, Files, FormSubmissions, FormationDocuments, Formations, Forms, ForumPosts, Images, Invoices, Jobs, Leads, LegalPages, Lessons, LinkItems, Logs, Me, OrderItems, Orders, Phone Consents, Phone Numbers, Phone Suppressions, PriceVariants, Products, Refunds, Reviews, Schedules, Secrets, Sites, Skills, Socials, Status, Subscriptions, Tags, TaskRuns, Tasks, Topics, Usage, Users, Video, Web, WebhookEndpoints, WebhookEvents.

• api_searchFree

  Discover available Crevio API endpoints. Use this BEFORE `api_execute` when you're unsure which endpoint to call, need to check parameter names, or want to explore what's available for a domain (e.g. "experiences", "discounts"). A `tools` method returns the full API catalog — an array of hashes keyed with strings: "method", "path", "summary", "description", "tags", "parameters", "request_body". Examples: `tools.select { |t| t["tags"]&.include?("Products") }.map { |t| "#{t["method"]} #{t["path"]} — #{t["summary"]}" }` `tools.find { |t| t["path"].include?("price_variants") && t["method"] == "POST" }["request_body"]` `tools.map { |t| t["tags"] }.flatten.compact.uniq.sort` — list all API domains

• ask_crevioFree

  Delegate a job to the Crevio agent and wait for the result. Starts a run that works your account through the Crevio API (products, customers, orders, email, socials, sites, research), waits up to timeout_seconds, and returns the run with the agent's final reply in `result`. For anything longer, use start_task and wait_for_run.

• cancel_runwrite actionFree

  Stop a run that is pending, running, or waiting for input. The run is finalized as failed with 'Cancelled by the caller'.

• get_chatFree

  Get a chat's title, kind, and latest run.

• get_runwrite actionFree

  Fetch a run's current status, summary, pending approvals, and (once settled) the agent's final reply.

• list_chatsFree

  List the account's chats, newest first.

• list_messagesFree

  Read a chat's messages, oldest first. Returns the most recent `limit` messages; page back through older ones with starting_after.

• list_runsFree

  List the account's task runs, newest first — delegated jobs and scheduled tasks alike. Filter by status or task.

• resolve_approvalsFree

  Approve or deny the integration actions a run is paused on (status needs_input with pending_approval_ids). Submit a decision for every pending id at once; the run resumes in the background.

• send_messagewrite actionFree

  Continue a chat with follow-up instructions or answers — the agent keeps its context. Resumes a run waiting in needs_input, or queues a new run when the last one finished. Returns run_busy while a run is still in progress. Optionally waits for the reply.

• start_chatFree

  Open a chat with the Crevio agent and queue a run, without waiting. Returns the run immediately — its `chat_id` is the conversation to continue with send_message. Follow the run with wait_for_run or get_run.

• wait_for_runwrite actionFree

  Wait for a run to settle (completed, failed, or needs_input) and return it with the agent's final reply. Returns wait_timed_out if it is still running when the timeout passes; call again.

• whoamiFree

  Identify the account, user, and credential behind this connection, with plan, credit balance, rate limits, and the tools available. Call it first to verify the setup.
