Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

account

get_account_state

Synthetic twin of the production tool. Returns an invented advertising account in the real response shape, marked "sandbox": true. Requires no account, API key, or OAuth flow.

performance

get_performance

Synthetic twin of the production tool. Returns invented reconciliation evidence in the real response shape, marked "sandbox": true. Requires no account, API key, or OAuth flow.

signal

get_signal_health

Synthetic twin of the production tool. Returns invented Signal health in the real response shape, marked "sandbox": true. Requires no account, API key, or OAuth flow.

validate

validate_sandbox_event

Validate a synthetic, identity-free conversion event against the Plainrouter schema. Requires no account, API key, or OAuth flow. Nothing is stored and nothing is sent to an advertising provider. Use this to confirm the server is reachable and that an event payload is well formed before requesting credentials.

PlainRouter — questions

Answers built from our own checks of this server.

What can PlainRouter do?

It exposes 4 tools, read directly from the server on our last check. Among them: get_account_state, get_performance, get_signal_health, validate_sandbox_event. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is PlainRouter working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 175 of 182 checks got a reply (96.2%), average response time 414 ms. The bar chart above shows every period we have measured.

Did PlainRouter ever remove tools?

Yes. launcher.batch_status, launcher.draft_batch, launcher.execute_batch, launcher.preview_batch and 9 more are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.

How do I connect PlainRouter?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does PlainRouter need an API key?

No. PlainRouter completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is PlainRouter?

It answers our handshake in 414 ms on average, which is faster than 40% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is PlainRouter open source?

Yes — it is published under the Apache-2.0 licence, written in Python and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
