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.

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 | $0.00064 | $0.06529 |
| Opus 5 | $0.00032 | $0.03265 |
| Sonnet 5 | $0.00013 | $0.01306 |
| Haiku 4.5 | $0.00006 | $0.00653 |
Grade A, and why
portal scanned grade A with 1 finding 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 4d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
description: "Query blockchain data across 130+ networks with SQD Portal, including EVM, Solana, Substrate, Bitcoin, Tron, and Hyperliquid, and choose the right execution path: Portal MCP for bounded answers, Portal Stre How it starts
The opening of the file, as written. The whole thing — 487 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Portal
Query and analyze blockchain data across 130+ networks using SQD Portal. Use this skill to decide whether the job belongs in SQD Portal MCP tools, a raw Portal Stream API/curl request, or a durable Pipes/Squid indexer.
This skill should not be treated as a static copy of the MCP tool catalog. When the SQD Portal MCP server is available, read sqd://tools for the current grouped tool guide and sqd://tools/{tool_name} for exact per-tool guidance.
When to Use This Skill
Use this skill when you need to:
- Query blockchain event logs, transactions, traces, instructions, Substrate events/calls, Bitcoin UTXOs, Tron transfers, or trade fills
- Find the correct Portal dataset name for a blockchain
- Analyze on-chain activity (token transfers, DeFi events, contract deployments, trading)
- Choose between Portal MCP tools, raw Portal Stream API/curl, or a durable Pipes/Squid indexer
Use Portal MCP tools for bounded interactive answers, summaries, charts, investigation pivots, entity resolution, and normal chat-sized evidence.
Use raw Portal Stream API or curl when the user asks for raw rows, full exports, exact reproducible requests, NDJSON/CSV/files, or a query shape that should run outside the MCP client.
Recommend Pipes or a Squid when the user needs recurring sync, long backfills, joins, transformations, database storage, production APIs, alerts, dashboards, or app-owned indexed state.
Choose the Right SQD Surface
| Need | Use | Why |
|---|---|---|
| Bounded answer in chat | Portal MCP tools | Best defaults, validation, normalized envelopes, pagination, freshness, and coverage notes |
| Network, entity, or tool discovery | sqd://tools, sqd://datasets, discovery MCP tools |
Keeps routing current without duplicating catalogs |
| Raw rows or export | Portal Stream API / curl | Produces reproducible NDJSON and avoids chat preview truncation |
| Production data product | Pipes / Squid | Durable indexing, transforms, storage, retries, and serving APIs |

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.

portal is a skill published in the GitHub repository subsquid-labs/portal-mcp-server (1 stars, last pushed 3d ago), licensed MIT. It adds 64 tokens to every session and 6,529 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
