Anlyon alternative

6 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

Why it is in this group
- The name "cancel_test_goal" says "cancel": a word for removing or ending something.
Description, as the server wrote it
Cancels a sandbox goal via POST /goals/:goalId/cancel, as the user's server would when a customer cancels: collected chunks (and a refundable deposit) are refunded in the ledger only, and goal.cancelled is sent.

check_api_keyConfirms this connector's test key works and shows its platform, scopes and mode.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Confirms this connector's test key works and shows its platform, scopes and mode. Run it before the other sandbox tools; if it fails, the message says what the user needs to fix.
Annotations the server declares
- readOnlyHint: true

Why it is in this group
- The name "create_test_goal" says "create": a word for a change.
What it can reach
- outboundThe input takes a URL (input.callbackUrl): a request to a URL can carry data to whoever runs it.
Description, as the server wrote it
Creates a goal with POST /goals/create using the test key. No money moves. Returns goalId, paymentUrl (hosted checkout) and clientSecret (embedded checkout). Amounts are integer cents, USD.

Why it is in this group

  What this check looks for
Description, as the server wrote it
Start here. Without an integration, explains the ways to add Trickl (own business such as a SaaS, or a multi-seller platform) and how to choose. With one, returns a step-by-step plan for the coding agent: keys, exact API calls, webhook handling, what to store, and how to prove it works with this server's sandbox tools.
Annotations the server declares
- readOnlyHint: true
register_test_providerRegisters a seller (provider) under the test key via POST /providers/register and returns providerLinkCode (needed to create goals) and webhookSecret (to verify webhooks).Can send data outNo findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
What it can reach
- outboundThe input takes a URL (input.webhookUrl): a request to a URL can carry data to whoever runs it.
Description, as the server wrote it
Registers a seller (provider) under the test key via POST /providers/register and returns providerLinkCode (needed to create goals) and webhookSecret (to verify webhooks). Idempotent on externalCreatorId. webhookUrl must be a public https URL that reaches the user's receiver, e.g. an ngrok or cloudflared tunnel to localhost. Sandbox webhooks are real signed HTTP requests.
Annotations the server declares
- readOnlyHint: false
simulate_goal_eventMoves a sandbox goal through its lifecycle instantly; each event sends the real signed webhook to the seller's webhookUrl, exactly as live would.No findings
Why it is in this group
- The description's first verb is "move": a word for a change.
Description, as the server wrote it
Moves a sandbox goal through its lifecycle instantly; each event sends the real signed webhook to the seller's webhookUrl, exactly as live would. confirm: the buyer signs up and links a bank (goal.deposit_paid if there is a deposit; for subscriptions also goal.subscription_created, plus goal.cycle_paid at once if the deposit paid the first period in full). collect: one round-up chunk, $3 by default (goal.round_up_collected); fails with ALREADY_FUNDED when the current period is already paid. complete: one-time goals finish (goal.completed); subscriptions pay the current period and start the next (goal.cycle_paid; the goal stays SAVING). payment_failed: a failed chunk (goal.payment_failed), with reversal=true for the clawback path. expire: a deadline goal fell short (goal.deadline_charge_failed). Confirm first.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged untrusted-input.

Reads private data2: Reads files, mail, messages, databases, secrets, calendars or repositories.; read_doc
search_docs
Reads text others write0: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out2: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.; create_test_goal
register_test_provider

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Findings

Matches of fixed checks, with the text they matched.

No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as trickl. Review it before you use it.
