Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Beschreibung vom Entwickler (englisches Original)
Inspect and score any MCP server 0-100 on publishability, schema and protocol before publish.
Diese drei werden nie zu einer Punktzahl zusammengefasst: Meinungen, Messungen und Beliebtheit sind verschiedene Dinge.
Für diesen Server haben wir noch keine Zusammenfassung in einfacher Sprache geschrieben. Unten stehen die Fakten, die wir aus der Registry gelesen haben.

One command to diagnose your MCP server.
Tests every tool, resource, and prompt your server exposes — then gives you a health report with a pass/fail scorecard.
Built on the Anthropic Model Context Protocol (MCP) spec.
Note: Published to npm as
@incultnitollc/mcp-probe. The CLI binary ismcp-probe. The unscoped namemcp-doctoron npm is owned by an unrelated tool, so this project ships under a scope. Versions<= 0.2.1shipped under the deprecated@incultnitostudiosllcscope — install@incultnitollc/mcp-probeinstead.
npx @incultnitollc/mcp-probe test "npx -y @modelcontextprotocol/server-everything"
| Check | Description |
|---|---|
| Tool calling | Calls every tool with auto-generated sample arguments based on the input schema |
| Resource reading | Reads every resource and verifies content is returned |
| Prompt rendering | Gets every prompt with sample arguments and verifies messages are returned |
| Schema validation | Checks tool schemas for missing descriptions, broken required fields, malformed types |
| Health scoring | Summarizes everything into a pass/fail scorecard |
npm install -g @incultnitollc/mcp-probe
Or run directly:
npx @incultnitollc/mcp-probe test "your-server-command"
npx @incultnitollc/mcp-probe test "npx -y @modelcontextprotocol/server-everything"
npx @incultnitollc/mcp-probe test https://your-server.example.com/mcp
npx @incultnitollc/mcp-probe test https://your-server.example.com/mcp --transport sse
npx @incultnitollc/mcp-probe test https://your-server.example.com/mcp \
--header "Authorization: Bearer $TOKEN"
| Flag | Description |
|---|---|
--json | Output results as JSON |
--timeout | Per-operation timeout (default 30000) |
--transport | Force stdio, sse, or http (auto-detected from target) |
--header | Add header to remote transport. Repeatable. |
0 — All checks passed1 — One or more checks failed (useful for CI gates)Use --json to get structured output for automation:
mcp-probe test --json "your-server" | jq '.score'
{
"toolsCallable": 12, "toolsTotal": 13, "resourcesReadable": 7, "resourcesTotal": 7, "promptsGettable": 3, "promptsTotal": 4, "schemaErrors": 0, "schemaWarnings": 1 }
mcp-probe auto-generates arguments for each tool based on its inputSchema:
default values and enum first choices when availableurl → https://example.com, email → test@example.com)string → "test", number → 1, boolean → false)This means tools with complex required inputs may fail — and that's useful information. It tells you your tool isn't self-contained enough for automated testing.
mcp-probe ships a second, complementary check: a publishability composite that scores your server 0–100 on whether its schemas, descriptions, and metadata are ready for other people to install. Run it as a shorthand:
npx @incultnitollc/mcp-probe score "npx -y @your-scope/your-server" --package ./package.json
Or fold it into a full test run with --publishability:
npx @incultnitollc/mcp-probe test "npx -y @your-scope/your-server" --publishability --package ./package.json
The composite combines three sub-scores — Protocol (does the wire format work), Edge cases (does it handle weird inputs), and Publishability (would a stranger understand your tools) — and a five-axis breakdown across the publishability dimension:
| Axis | What it checks |
|---|---|
description-five-axis | Per-tool description density across purpose, mutation, side-effects, invariants, examples. Tools below 3.0/5 axes fire a ≤60 composite cap. |
enum-shape | Catches prose-only enums (e.g. "one of: open, closed" in the description with no JSON Schema enum). |
mutation-legibility | Does each tool tell a planner it mutates, or only reads? Name prefix / description signal / annotation all count. |
anti-purpose-clause | High-blast tools (delete, send, transfer) should include a "do not use for X, prefer Y" pointer to a narrower tool. |
distribution-metadata | npm package readiness — description length, keyword count, repository / license / homepage fields. Skipped without --package. |
The five official Anthropic MCP servers all land at 60/100 under v1.1.0 — the description-five-axis cap fires on every one. That's not a bug in the rubric; that's the bar Anthropic ships at, and the bar most servers will start from. Full scorecards in docs/publishability-scorecards/.
- uses: incultnitollc/mcp-probe@v1
with: command: 'node dist/index.js' publishability: 'true' package: './package.json' fail-under: '70'
mcp-probe's publishability score is the pre-publish quality lane — for server authors before they ship. For the install-time security lane — server installers before they connect a third-party server — see @stephenywilson/mcp-doctor. Different audiences, complementary tools.
test/score tell you if your server is healthy *today*. Contract testing tells you what changed since last time — so a breaking schema edit or a poisoned tool description never ships silently.
Record a snapshot of your server's contract (its tools, resources, prompts, and their schemas — no traffic, no side effects), commit the .mcpvcr file, then diff or gate every PR against it.
# 1. Record a baseline (lists only — never calls a tool)
mcp-probe record "node dist/index.js" --out .mcp/contract.mcpvcr git add .mcp/contract.mcpvcr && git commit -m "record MCP contract baseline"
mcp-probe diff --baseline .mcp/contract.mcpvcr "node dist/index.js"
mcp-probe gate --baseline .mcp/contract.mcpvcr "node dist/index.js"
Every change is classified so the gate is meaningful, not noisy:
| Severity | Examples |
|---|---|
| ❌ breaking | tool removed · new required argument · property removed · type changed · enum narrowed |
| ⚠️ security | tool description mutated (rug-pull / tool-poisoning) · readOnlyHint dropped · tool became destructive |
| ✅ additive | new tool · new optional field · enum widened |
| ℹ️ info | server name · resource/prompt description text |
gate fails on breaking,security by default — tune with --fail-on breaking (or any comma-separated set). Snapshots are deterministic: re-recording an unchanged server produces a byte-identical file, so committed baselines and diffs stay clean. Compare two recorded files offline with --against instead of a live target, and write a ready-to-post PR comment with --markdown .
Why it matters: the 2026-07-28 MCP spec ships breaking changes (dropped initialize handshake, error-code and JSON-Schema shifts, HTTP+SSE → Streamable HTTP). A recorded .mcpvcr baseline turns "did we break our clients?" into a one-line CI check. See examples/contract-gate.yml for the full PR workflow with auto-commenting.
mcp-probe exits 0 on full pass and 1 on any failure, so it drops directly into any CI pipeline:
# .github/workflows/mcp-health.yml
Use --json for structured output and jq to gate on specific metrics (e.g. fail the build if schemaWarnings > 0).
Drop mcp-probe into your MCP server's GitHub Actions workflow in two lines:

with: command: 'node dist/index.js'
Gate your PRs on a publishability composite:
- uses: incultnitollc/mcp-probe@v1
with: command: 'node dist/index.js' publishability: 'true' package: './package.json' fail-under: '70'

The official MCP Inspector is a GUI for interactive exploration — point, click, see what a server returns. mcp-probe is a CLI for automated, repeatable diagnosis — every tool/resource/prompt called automatically, pass/fail scorecard out, exit code in. Use Inspector when you're exploring; use mcp-probe in CI, in pre-publish checks, or when you want a shareable scorecard of someone else's server.
