Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Runs an external command apiwatch/mcp_client.py:170

        self.proc = subprocess.Popen(argv, stdin=subprocess.PIPE, stdout=subprocess.PIPE,

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 7

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

changes

search_changes

Search apiwatch's feed of reviewed vendor changes by text: a case-insensitive match on each record's summary, vendor and signatures (the strings to look for in code). Use it when you know a product or feature name but not the exact id. Newest key date first; default 20 results, max 50.

identifiers

check_identifiers

Look up many identifiers at once before shipping code: model ids, API endpoints (/v1/assistants), MCP tool names, SDK methods or field names. For each one, a one line answer and the ids of matching records, plus the records themselves. A record scoped to some code (for example only repos that depend on a given SDK major version) is returned with that scope spelled out, never as an unconditional hit. Max 100 identifiers.

mcp

mcp_server_changes

Before you rely on a public MCP server's tools, ask whether apiwatch saw them change: tools removed or renamed, new required parameters, rewritten descriptions, changed safety hints. Give a watched server's slug, URL or registry name. Returns a one line answer and the confirmed changes in the last N days (default 90, max 365), newest first, with flags worth a look. Observations only: no changes is not a statement that a server is safe. Never includes tool description text.

model

check_model

Look up one AI model id (for example gpt-4o-2024-05-13 or claude-sonnet-4-5) in apiwatch's reviewed feed of vendor changes before you use it in code. Returns a one line answer (when it stops working, changes behavior, or its deprecation key date) and each matching record with the date, what to do and the replacement, and links to the record and the vendor's source. "No record" means apiwatch has no record for it, not that it is safe. Records that apply only in some repos or files say so in scope.

record

get_record

Get one apiwatch record in full, as published: what changes, what to do, the strings to search for, ids it does not cover, where it applies, the vendor source and when it was reviewed. Use an id from another tool's result.

upcoming

list_upcoming

List the dated changes in apiwatch's feed from today forward, soonest first: model retirements, breaking API changes, silent behavior changes and deprecation key dates. Use it to plan migrations. Optionally limit to the next N days (default 90, max 365) or one vendor. Max 50 records.

watched

list_watched_mcp_servers

List the public MCP servers whose tools apiwatch checks every 6 hours (tools/list only, no login, no tool calls), with each one's status (answering, needs a login, not reachable), tool count, last check and last observed change. Use it to see which servers mcp_server_changes can answer about. Returns no tool descriptions.

apiwatch — questions

Answers built from our own checks of this server.

What can apiwatch do?

It exposes 7 tools, read directly from the server on our last check. Among them: check_identifiers, check_model, get_record, list_upcoming, list_watched_mcp_servers, mcp_server_changes and 1 more. 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 apiwatch working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 233 ms. The bar chart above shows every period we have measured.

How do I connect apiwatch?

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

Does apiwatch need an API key?

No. apiwatch completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is apiwatch?

It answers our handshake in 233 ms on average, which is faster than 70% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is apiwatch open source?

The code is open source: it is published under the MIT licence, written in Python and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at apiwatch.reignventures.co, which runs on its operator's own terms.
