A toolkit for building and running blockchain indexers, which collect blockchain activity and store it in a database or analytics system. It supports EVM chains, Solana, Tron, Bitcoin, and Hyperliquid.

Use it to create, configure, troubleshoot, optimize, and deploy indexers. It can send indexed data to ClickHouse, PostgreSQL, BigQuery, Parquet files, or Google Pub/Sub.

It turns a one-time data export into a service that can keep syncing, handle backfills, and recover from common errors. It also helps check whether the collected data is complete and clean.

Token cost

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	$0.00062	$0.05232
Opus 5.5	$0.00025	$0.02093
Sonnet 5.5	$0.00012	$0.01046
Haiku 4.5	$0.00006	$0.00523

Security

Grade A, and why

pipes-sdk 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 274 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Pipes SDK

One skill for the full Pipes SDK lifecycle: scaffold new indexers, diagnose runtime errors, optimize sync performance, and validate data quality.

When to Use This Skill

Activate when the user wants to:

Create a new indexer — scaffold EVM or Solana projects with the CLI; set up Tron, Bitcoin, or Hyperliquid indexers manually with the SDK
Fix runtime errors — compilation failures, DB issues, Portal timeouts, decoding errors
Optimize sync performance — slow indexing, high memory, large ranges
Validate data quality — NULL checks, gaps, malformed addresses, duplicate events
Deploy an indexer — local Docker or ClickHouse Cloud
Write to analytics sinks: ClickHouse, PostgreSQL (Drizzle), BigQuery, Parquet files, Google Pub/Sub
Turn a Portal handoff into durable infrastructure — when a Portal MCP answer or curl export is not enough

Common trigger phrases: "create a new indexer", "my indexer crashed", "error", "not working", "slow", "optimize", "deploy to ClickHouse Cloud", "track X events on Ethereum/Solana/Tron/Bitcoin/Hyperliquid".

Portal Handoff Workflow

Use Pipes when a Portal MCP or raw Stream API workflow crosses from exploration into a maintained data product.

Good Pipes triggers:

long historical backfills
recurring syncs or scheduled refresh
protocol-specific joins
normalized tables for an app/backend
custom metrics, alerts, or dashboards
transforms that should be versioned and tested
data too large for MCP chat responses or one-off curl files

If the input includes a Portal pipes_handoff recipe, preserve its network, filters, time window, outputs, and validation hints. Treat the Portal MCP/curl result as the baseline, scaffold the indexer, and validate the first output against the closest Portal query over the same bounded window.

Before scaffolding, say why Pipes is the right surface. Portal MCP is best for bounded answers and investigation pivots; Portal Stream API/curl is best for reproducible one-off extraction; Pipes is best for durable indexing, transforms, and storage.

pipes-sdk is a skill published in the GitHub repository subsquid-labs/portal-mcp-server (2 stars, last pushed 1mo ago), licensed MIT. It adds 62 tokens to every session and 5,232 once invoked, about $0.0002 per session on Opus 5.5. 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.
