Common questions

Is MarkMesh safe?

It passed 3 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed 3 months ago, and the latest version (1.0.0) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

What can I use instead?

MarkMesh MCP — trademark data your agent can cite

Connect Claude (Desktop or Code), or any Model Context Protocol client, to MarkMesh: a normalised trademark corpus across 30+ national and regional registers.

Three things this gives an agent that a wrapper around office APIs cannot:

  • Provenance on every record. Which register it came from, when we fetched it, and a link to that office's own entry where the office publishes one. Your agent cites us, we cite the register.
  • Monitoring, not just search. Register a watch and poll what changed. Monitoring needs something persistent to compare against, and a pass-through proxy holds nothing between calls.
  • Predictable lookups. Most registers are served from our own store, so a lookup doesn't wait on an office API. Where we do query an office live, the response says so. See the live coverage table.

For trademark lawyers and IP teams who want their portfolio one question

away, and for builders putting trademark data underneath their own product.

Quickstart

  1. Get an API key — in MarkMesh, go to *Developers → API keys* (mm_test_… to experiment, mm_live_… for a real portfolio).
  2. Add the connector — point your client at https://markmesh.com/api/v1/mcp with header Authorization: Bearer . Full steps in [SETUP.md](SETUP.md).
  3. Ask — restart your client and try one of the questions below.

Thirty seconds in

Once connected, this is the shape of a real exchange:

You:  Is "Kestrel" already taken in software, in the EU and UK?

Claude: I checked EUIPO and UKIPO for classes 9 and 42.

Three candidates, closest first:

KESTREL EUIPO 018745231 registered text similarity 1.00 · shares classes 9, 42 · same territory https://euipo.europa.eu/eSearch/#details/trademarks/018745231 (from our corpus, fetched 30 Jul 2026)

KESTRAL UKIPO UK00003891234 registered text similarity 0.94 · shares class 9 · same territory https://trademarks.ipo.gov.uk/...

KESTREL LABS EUIPO 018991002 pending text similarity 0.72 · shares class 42 · same territory

Both offices answered, so nothing is missing from this run.

I can't tell you whether the name is clear to use. That turns on how the goods and services are worded and whether these marks are actually in use, which needs a qualified professional. Want me to watch the pending one for status changes?

Note what it does not say. There's no risk score and no verdict, because the API deliberately returns neither.

What you can ask

You sayIt uses
"List my trademarks for client Acme."list_trademarks, list_clients
"What's expiring in the next 90 days?"list_filings (deadline fields)
"Search USPTO and EUIPO for 'orbital'."search_office
"Does 'Kestrel' conflict with anything in class 9?"search_conflicts
"Import EU trademark 018xxxxxx for Acme."import_filing_from_office
"Tell me if that filing's status changes."create_watch
"What changed since Monday?"watch_changes_since

Build on it

  • [examples/watch_bot.py](examples/watch_bot.py) — a complete monitoring bot in one file, standard library only. Fork it.
  • [SKILL.md](SKILL.md) — the agent skill: drop it in a Claude Code skills dir, or use it as guidance for any MCP client.
  • [reference/tools.md](reference/tools.md) — full tool + argument reference, including what every response guarantees.
  • [SETUP.md](SETUP.md) — get a key and wire up Claude Desktop / Claude Code.
  • [llms.txt](https://markmesh.com/llms.txt) — machine-readable summary of the whole surface.

Capabilities & limits

  • Read trademarks, filings (with renewal/expiry deadlines), clients and organisations.
  • Search registers for marks, and run conflict research against a shortlist of names, scoped by Nice class.
  • Import a filing into the portfolio, and refresh an existing one.
  • Watch a filing and poll what changed.
  • Scoped & safe: every request is limited to the key's organisation and gated by the same permissions as the app. There are no delete tools over MCP; destructive edits stay in the web app.
  • Not legal advice. MarkMesh returns trademark data with its provenance. Whether a mark is available to use is a legal judgement for a qualified professional, and the conflict tool returns no verdict by design.
  • Sandbox: a mm_test_* key gets its own isolated portfolio — trademarks, filings, clients and watches are separate from any live organisation. Office search is not sandboxed: search_office and search_conflicts read the same public register corpus a live key does, so a sandbox search returns real marks, not fixtures. That is deliberate (registers are public data, not tenant data) and it means you can evaluate real cross-office coverage before you pay. Only calls that go out to a live office adapter are routed to test endpoints.
