What is mcp AGENTS.md?

Repository instructions for a remote MCP server for the Sevalla hosting platform. They describe the project, required Node.js version, development and test commands, formatting, linting, and type checking.

Use them when modifying the Sevalla MCP server, running its tests, checking TypeScript, linting code, or formatting files.

They tell coding agents how this repository is structured and how to verify changes correctly.

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	$0.02685	$0.02685
Opus 5.5	$0.01074	$0.01074
Sonnet 5.5	$0.00537	$0.00537
Haiku 4.5	$0.00268	$0.00268

Security

Grade A, and why

mcp 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 21d 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.

Project Overview

Remote MCP server for the Sevalla PaaS API (mcp.sevalla.com). Exposes 27 tools: 22 purpose-built workflow tools and 5 generic tools that run any other v3 operation by operation ID, split into read, create, update and delete. Built with Hono and MCP SDK v2 (@modelcontextprotocol/server); it serves the 2026-07-28 protocol and 2025-era clients from the same tools. No build step — TypeScript runs natively on Node.js 26 (24 also works).

Commands

pnpm dev              # Development with --watch (native Node.js)
pnpm start            # Run server (node src/index.ts)
pnpm test             # Run unit and e2e tests (node:test), e2e in both protocol eras
pnpm test:e2e         # End-to-end tests in both eras (real HTTP server, MCP SDK client, fake Sevalla API)
pnpm test:live        # Live checks: client metadata documents; API smoke test with SEVALLA_E2E_API_KEY
pnpm sync:operations  # Regenerate src/sevalla/operations.json from the live API spec
pnpm lint             # oxlint
pnpm fmt              # oxfmt (auto-fix)
pnpm fmt:check        # oxfmt (check only)
pnpm check:code       # Full check: tsc --noEmit --skipLibCheck && oxlint && oxfmt --check

Running a Single Test

node --test test/oauth.test.ts          # Run one test file
node --test --test-name-pattern="encrypt" test/oauth.test.ts  # Run matching tests

The test runner is node:test (built-in). No Jest, Vitest, or Mocha.

Type Checking

npx tsc --noEmit --skipLibCheck

Node.js Version

Node.js 26 (.nvmrc, Volta, Docker); Node.js 24 is supported and tested in CI. TypeScript runs via Node's built-in type stripping — there is no build/compile step, so only erasable syntax works (no enums, namespaces or parameter properties). pnpm 12 (packageManager); its settings go in pnpm-workspace.yaml when needed (there is none today), and it refuses packages published less than a day ago.

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.
