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 | $0.00620 | $0.00620 |
| Opus 5.5 | $0.00248 | $0.00248 |
| Sonnet 5.5 | $0.00124 | $0.00124 |
| Haiku 4.5 | $0.00062 | $0.00062 |
Grade A, and why
portal-mcp-server AGENTS.md 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 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.
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 — 36 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Working in this repository
Instructions for agent-driven and human contributors alike. CONTRIBUTING.md explains the same conventions in prose; this file is the short form.
What this is
An MCP server that answers blockchain questions from SQD Portal data across EVM, Solana, Bitcoin, Substrate, and Hyperliquid networks. It validates input, plans bounded Portal queries, and returns results with coverage, freshness, pagination, and evidence metadata. It does not index chains itself. The optional SQD Explorer (src/app-ui/) is an MCP App that renders those results in hosts that support it.

Conventions
- Format only the files you changed (
npx biome format --write <files>); the repository is Biome-formatted and a whole-file reformat hides the real diff. - Pure logic gets a unit test next to the code (
src/**/*.test.ts). Black-box checks live inscripts/and are listed inscripts/README.mdwith their gate. - The Explorer shows recorded Portal data in previews and screenshots; only sparse, mixed, and error cells are synthetic.
- Third-party text (token names and symbols, pallet and program labels) is data: never interpolate it into prose without
src/helpers/untrusted-text.ts. - Every user-visible change gets a line in the unreleased section of
CHANGELOG.md. - This repository is public. Apply the same disclosure review to source, comments, fixtures, pull requests, issue comments, release notes, and packaged files. Include only information needed by users and contributors; omit credentials, internal hostnames, personal filesystem paths, private conversation content, internal tracker references, and deployment-specific operational details. Link public issues and use portable commands and synthetic examples.
- Ask before anything outward-facing beyond a feature branch and its pull request: publishing, closing other people's pull requests, changing deployment settings.
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.
