scrum4me-mcp

MCP server for Scrum4Me. Exposes the dev-flow as Model Context Protocol tools and prompts so Claude Code (or any MCP-compatible client) can read context, update tasks, log activity and create todos via native tool calls instead of curl.

Tools

Tool	Purpose	Demo write?
health	Service + DB ping	n/a
list_products	Active products the user owns or is a member of	n/a
get_claude_context	Bundled product + active sprint + next story (with tasks) + open todos	n/a
update_task_status	Set status to todo, in_progress, review, done	no
update_task_plan	Save/replace implementation_plan on a task	no
log_implementation	Append IMPLEMENTATION_PLAN to a story log	no
log_test_result	Append TEST_RESULT (PASSED/FAILED)	no
log_commit	Append COMMIT with hash and message	no
create_todo	Add a todo, optionally scoped to a product	no
create_pbi	Add a Product Backlog Item to a product (auto sort_order)	no
create_story	Add a story under a PBI (status=OPEN, lands in product backlog)	no
create_task	Add a task under a story (status=TO_DO, inherits sprint_id)	no
ask_user_question	Post a question to the active user about a story; optional wait_seconds (max 600) polls for the answer	no
get_question_answer	Fetch the current status + answer of a previously-asked question	n/a
list_open_questions	List own open/answered questions, most recent first (max 50)	n/a
cancel_question	Cancel an own open question (asker-only)	no
wait_for_job	Block until a QUEUED ClaudeJob is available, claim it atomically, return full task context with frozen plan_snapshot	no
update_job_status	Report job transition to running, done, or failed; triggers SSE event to UI	no
verify_task_against_plan	Compare frozen plan_snapshot against current plan + story logs + commits; returns per-AC ✓/✗/? heuristic and drift-score	yes (read-only)

Demo accounts may read but writes return PERMISSION_DENIED.

verify_task_against_plan

Compares the immutable snapshot captured at claim time against the current state of the work. Useful at the end of a job to self-assess completeness.

Input

{ "task_id": "cmolqlqvh0023q..." }

Output

# Verify task: Prisma-schema + migratie in Scrum4Me (cmolqlqvh...)

## Plan
- Snapshot: - Bewerk prisma/schema.prisma:...
- Current: - Bewerk prisma/schema.prisma:...
- Edited onderweg: **no**

## AC-checks (5/6 ✓ — drift-score 83%)
- ✓ Scrum4Me prisma/schema.prisma: nieuw veld plan_snapshot...
- ✓ Migratie aangemaakt en getest
- ✗ vendor/scrum4me submodule in scrum4me-mcp gebumpt

## Realisatie
- 1 log_implementation-entry
- commit `a3af2dd` — feat: add plan_snapshot field to ClaudeJob schema

⚠️ Heuristiek-rapport — handmatige PR-review blijft nodig

Beperkingen heuristiek

• Zoekt op sleutelwoorden (filenames, camelCase-identifiers, lange woorden) — geen semantisch begrip
• AC's die alleen over externe verificatie gaan (deployment, user-test) scoren altijd ✗ zonder extra log-entries
• Plan_snapshot is NULL voor jobs die zijn geclaimed vóór versie met snapshot-feature — rapport meldt "no baseline"
• Gebruik het rapport als startpunt, niet als definitief oordeel; PR-review blijft leidend

Prompts

• implement_next_story — full workflow: fetch context, log plan, walk tasks, run tests, commit. Takes product_id.

Setup

git clone --recurse-submodules https://github.com/madhura68/scrum4me-mcp.git
cd scrum4me-mcp
npm install              # postinstall runs prisma generate
cp .env.example .env     # fill in DATABASE_URL and SCRUM4ME_TOKEN
npm run build
npm link                 # exposes the `scrum4me-mcp` bin globally

SCRUM4ME_TOKEN comes from Scrum4Me → Instellingen → Tokens (/settings/tokens). The token is hashed with SHA-256 and looked up in the same api_tokens table the REST API uses.

DATABASE_URL points to the same Postgres database Scrum4Me runs against — typically the Neon connection string from the Scrum4Me project's .env.

Use with Claude Code

Add to ~/.claude/mcp_servers.json:

{
  "mcpServers": {
    "scrum4me": {
      "command": "scrum4me-mcp",
      "env": {
        "DATABASE_URL": "postgresql://...",
        "SCRUM4ME_TOKEN": "..."
      }
    }
  }
}

Restart Claude Code. The 9 tools and 1 prompt show up under the scrum4me namespace.

Schema sync

The Prisma schema is the source of truth in the upstream Scrum4Me repo. It is vendored as a git submodule under vendor/scrum4me:

git submodule update --remote vendor/scrum4me
npm run sync-schema      # copies prisma/schema.prisma, strips erd block
npm run prisma:generate
git commit -am "chore: sync schema with scrum4me@<sha>"

sync-schema.sh strips the upstream generator erd block so this package does not depend on prisma-erd-generator.

Development

npm run dev              # tsx src/index.ts (stdio)
npm run typecheck
npm run build

Quick local smoke-test with the official MCP inspector:

npx @modelcontextprotocol/inspector node dist/index.js

Risks

• Schema drift — Prisma Client and live DB can diverge if the upstream schema changes without a sync. Re-run sync-schema and prisma:generate whenever Scrum4Me ships a migration.
• Token in plain text — mcp_servers.json stores SCRUM4ME_TOKEN unencrypted. Use ${env:SCRUM4ME_TOKEN} and a real keychain for shared machines.
• Concurrent updates — no optimistic locking. Same caveat as the REST API.
• Production database — verify against a preview database before running against prod. The token check enforces user scope but does not gate reads of unrelated products you happen to be a member of.
