A collection of standard project commands for building, testing, linting, running, inspecting, and generating metadata for a TypeScript MCP server. Vitest is the test framework named in the instructions.

Building the project, running tests and coverage, fixing lint issues, starting the server locally, inspecting it, and generating or checking metadata.

It gives developers one documented way to check code, run tests, start the server, and verify generated metadata.

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	$0.00017	$0.00442
Opus 5.5	$0.00007	$0.00177
Sonnet 5.5	$0.00003	$0.00088
Haiku 4.5	$0.00002	$0.00044

Security

Grade A, and why

dev-toolkit 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 2mo 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.

# Watch mode
npm run test:watch

3. Lint

Checks the code for style and potential errors.

# Check linting
npm run lint

# Fix linting issues where possible
npm run lint:fix

4. Run Locally (MCP Mode)

Starts the MCP server in stdio mode (for testing with Inspector or local clients).

# Start server
npm start

# Debug with MCP Inspector
npm run inspect:stdio

5. Metadata Generation

Commands for managing the awesome-copilot metadata.

# Generate full metadata
npm run generate-metadata

# Generate LEAN metadata (recommended for basic dev)
npm run generate-metadata:lean

# Verify metadata integrity
npm run generate-metadata:verify

# Check metadata size
npm run check:metadata-size

6. HTTP Server & Inspection

Commands for running the server in HTTP mode and inspecting it.

# Start HTTP server
npm run start-http

# Start HTTP server (debug mode with port 8080)
npm run start-http:debug

# Inspect using MCP Inspector (Stdio) - Recommended for CLI
npm run inspect:stdio

# Inspect using MCP Inspector (HTTP)
npm run inspect:http

7. Debugging & Maintenance

Helper commands for debugging and maintenance.

# Debug CLI directly
npm run debug:cli

# Archive large reports
npm run archive:reports

# Clean build artifacts
npm run clean

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.
