Bring your agent

1 · Create a token

Sign in (one text, phone-only — no passwords here) and mint your token right on this page — agent access comes with a subscription, either tier. It scopes every request to your collection, is shown exactly once, and can be revoked anytime from Settings → Agent access.

2 · Paste this prompt into your agent

Manage my texttcg card collection for me.

Setup: GET https://texttcg.com/api/agent for the API docs. Authenticate every
request with the header  Authorization: Bearer <PASTE-YOUR-TOKEN-HERE>
(all operations act only on my collection).

Then take my instructions in plain English and make the right API calls. For
example: "log a van gogh pikachu psa 10 for $500 basis", "add the phantasmal
flames charizard sir for $4 and mark it sold for $10", "tag my mews as grail",
"what am I holding and what did I pay?". Use the catalog search when a card is
ambiguous, prefer exact printings, and confirm what you did with card names
and ids. If a card isn't in the catalogs (like sports cards), add it as a
custom entry with the full name I gave (and pass my set name as its set, if
I mention one).

Walkthrough · Claude in your terminal

$ claude
> [paste the prompt from step 2, with your token filled in]

  Got it — I fetched the texttcg API docs. Ready for your cards.

> log a van gogh pikachu psa 10 for $500 basis

  ✓ Added Pikachu with Grey Felt Hat (svp-085 · SVP Black Star
    Promos) — cost basis $500. Want me to record the PSA 10 grade
    on it? (done ✓)

> add phantasmal flames charizard sir for $4, sold it for $10

  ✓ Added Mega Charizard X ex (me02-125 · Phantasmal Flames),
    $4 basis, marked sold for $10 — realized +$6.

> what am I holding?

  1 owned: Pikachu with Grey Felt Hat (PSA 10) — $500 basis.
  1 sold: Mega Charizard X ex — +$6 realized.

That's the whole loop: paste once, then it's just conversation. Everything lands in your portfolio here the moment the agent confirms it.

Claude-native (MCP)

Claude Code users can connect once and get first-class tools instead of raw HTTP:

claude mcp add --transport http texttcg https://texttcg.com/api/mcp \
  --header "Authorization: Bearer ttcg_..."

Same tools, same account scoping: list, search the catalogs, add (including custom sports entries), edit, sell.
