workflows-mcp-server CLAUDE.md

workflows-mcp-server CLAUDE.md is an instructions file for coding agents from cyanheads/workflows-mcp-server. It costs 5,758 tokens per session, scanned A, a copy of obsidian-mcp-server AGENTS.md, Apache-2.0.

A project instruction file for building an MCP server with Bun or Node. MCP is a standard way for an AI agent to use tools, data sources, and prompts provided by another program.

In plain words
What is it for?
Designing and adding server tools, data resources, prompts, services, and tests, then checking that those definitions work.
Why use it?
It tells the agent which project conventions and framework documentation to follow, reducing inconsistent server changes. It also suggests the next development task based on the project's current state.

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.

Security

Grade A, and why

workflows-mcp-server CLAUDE.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 today.

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.

Origin

This is a copy

77% identical to obsidian-mcp-server AGENTS.md — 310 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 365 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Agent Protocol

Server: @cyanheads/workflows-mcp-server Version: 0.3.1 Framework: @cyanheads/mcp-ts-core ^0.12.5 Engines: Bun ≥1.3.0, Node ≥24.0.0 MCP SDK: @modelcontextprotocol/server ^2.0.0 Zod: ^4.5.4

Read the framework docs first: node_modules/@cyanheads/mcp-ts-core/CLAUDE.md contains the full API reference — builders, Context, error codes, exports, patterns. This file covers server-specific conventions only.


What's Next?

When the user asks what's next or needs direction, suggest options based on the current project state. Common next steps:

  1. Re-run the setup skill — ensures CLAUDE.md, skills, structure, and metadata are populated and up to date with the current codebase
  2. Run the design-mcp-server skill — if the tool/resource surface hasn't been mapped yet, work through domain design
  3. Add tools/resources/prompts — scaffold new definitions using the add-tool, add-app-tool, add-resource, add-prompt skills
  4. Add services — scaffold domain service integrations using the add-service skill
  5. Add tests — scaffold tests for existing definitions using the add-test skill
  6. Field-test definitions — exercise tools/resources/prompts with real inputs using the field-test skill, get a report of issues and pain points
  7. Run devcheck — lint, format, typecheck, and security audit
  8. Run the security-pass skill — audit handlers for MCP-specific security gaps: output injection, scope blast radius, input sinks, tenant isolation
  9. Run the polish-docs-meta skill — finalize README, CHANGELOG, metadata, and agent protocol for shipping
  10. Run the maintenance skill — investigate changelogs, adopt upstream changes, and sync skills after bun update --latest

Tailor suggestions to what's actually missing or stale — don't recite the full list every time.


Core Rules

  • Logic throws, framework catches. Tool/resource handlers are pure — throw on failure, no try/catch. Plain Error is fine; the framework catches, classifies, and formats. Use error factories (notFound(), validationError(), etc.) when the error code matters.
  • Use ctx.log for request-scoped logging. No console calls.
  • Use ctx.state for tenant-scoped storage. Never access persistence directly.
  • Need caller input? Return ctx.requestInput(...); the handler is re-entered with answers in ctx.inputs. Never await input mid-handler.
  • Secrets in env vars only — never hardcoded.
  • Close the loop on issues. When implementing work tracked by a GitHub issue, comment on the issue with what landed and close it. Do both — a comment without a close leaves stale issues open; a close without a comment leaves no record of what shipped. The comment is for future readers — state the concrete changes, not the conversation that produced them.

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.
