claude-plugins-community is a read-only mirror of a marketplace listing community-contributed plugins for Claude Cowork and Claude Code. It is for discovering and installing plugins that extend those Claude products, while submissions are handled through Anthropic’s separate review process. Catalogue add-ons represent plugins, skills, and integrations associated with this marketplace.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00201 | $0.02192 |
| Opus 5 | $0.00101 | $0.01096 |
| Sonnet 5 | $0.00040 | $0.00438 |
| Haiku 4.5 | $0.00020 | $0.00219 |
Grade A, and why
tres-import-contacts scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 180 lines — stays where its author put it; the contents beside it link to each section on GitHub.
TRES Finance — Import Contacts from CSV/XLSX
Goal
Read a user-provided CSV or XLSX file containing address-to-name mappings and import them as contacts into the TRES address book. This is the second half of the contacts workflow: the user previously exported unidentified addresses (via the export skill), filled in names and tags, and now wants to push those labels back into TRES.
MCP Server
All GraphQL calls use the user-tres-finance MCP server (execute tool).
Expected File Format
The file should have these columns (header names are matched case-insensitively):
| Contact Name | Contact Address | Contact Tag |
|---|---|---|
| Binance Hot Wallet | 0xABC... | Exchange |
| Vendor X | 0xDEF... | Vendor |
- Contact Name — the label to assign to the address (required for import; rows without a name are skipped)
- Contact Address — the blockchain address (required)
- Contact Tag — optional tag(s) for the contact. Multiple tags can be separated by commas (e.g.
Exchange, Custodian)
The column order doesn't matter — the skill matches by header name. The file may contain additional columns (like the "Address details" enrichment columns from the export skill) — those are ignored.
Workflow
Step 1 — Authenticate
Call get_viewer (no arguments) to confirm the session is active and note the organization name.
Step 2 — Read and parse the file
The user will provide a CSV or XLSX file. Detect the format from the file extension.
For XLSX files:
Use Python with openpyxl==3.1.5. If not installed, stop and display:
"openpyxl is not installed. Please run:
python3 -m venv .venv && .venv/bin/pip install openpyxl==3.1.5"
- If the workbook has multiple sheets, look for one named "Contacts" (case-insensitive). If not found, use the first sheet.
- Read the header row to find the column indices for "Contact Name", "Contact Address", and "Contact Tag" (match case-insensitively, trim whitespace).
- Read all data rows.
- Filter out trailing empty rows — openpyxl sometimes reads extra
Nonerows at the bottom of the sheet. Skip any row where all cells areNoneor empty strings.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

tres-import-contacts is a skill published in the GitHub repository anthropics/claude-plugins-community (3,663 stars, last pushed 15d ago), licensed Apache-2.0. It adds 201 tokens to every session and 2,192 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
