mcp-planner CLAUDE.md

Project instructions for building an MCP server that connects Microsoft Planner with Microsoft Graph, Microsoft's API for accessing its services.

In plain words
What is it for?
Building, testing, running, and packaging the Microsoft Planner integration, including its Graph API client, HTTP access, and MCP tools.
Why use it?
They document the expected commands, architecture, authentication, resource types, and update rules so contributors can extend the server consistently.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

mcp-planner 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md

MCP server for Microsoft Planner via Microsoft Graph. Sibling project to mcp-connectwise-psa (copied from it) and mcp-itglue — same architecture.

Commands

  • npm run build — tsc to dist/
  • npm test — vitest
  • npm run dev / npm run dev:http — tsx, stdio or HTTP transport
  • npm run bundle — build the Claude Desktop .mcpb

Architecture

  • src/index.ts — CLI entry; --transport stdio|http, --port; USAGE text
  • src/config.ts — loadConfig(argv, env) → ServerConfig; ConfigError; MS_* env vars
  • src/server.ts — createServer(session) builds a per-session McpServer; INSTRUCTIONS string
  • src/graph/client.ts — GraphClient: client-credentials token (cached, 60s skew), get/getList/post/patch/delete; PATCH/DELETE take an explicit etag (If-Match); PATCH sends Prefer: return=representation; GraphApiError + describeError
  • src/graph/types.ts — Graph resource shapes; priorityLabel/PRIORITY_VALUES/progressLabel
  • src/http/app.ts — Express app; BYOK via x-ms-tenant-id/x-ms-client-id/x-ms-client-secret headers with fallback to server env creds; session principal pinned by SHA-256 hash
  • src/tools/registrar.ts — ToolRegistrar; no MCP-level role gating (Graph is the access control)
  • src/tools/shared.ts — zod fragments (responseFormatField, topField), text/failure/json/clip
  • src/tools/{groups,plans,tasks}.ts — planner_* tools; plans.ts includes planner_list_my_plans (/me/planner/plans delegated, /users/{id}/planner/plans with user_id)
  • src/tools/session.ts — planner_whoami: app-only vs delegated (+ acting user via /me); mode detection is GraphClient.isDelegated
  • src/tools/advanced.ts — opt-in escape hatch (PLANNER_ADVANCED_TOOLSET=true / --advanced, off by default): graph_get (read-only GET via the verb-locked GraphClient.get, allowlisted to /planner, /groups, /users — plus /me on delegated sessions; /beta rejected; a pasted @odata.nextLink works as path — its inline query is parsed and merged, structured args win) and graph_find_endpoint (lexical search over the hand-maintained src/reference/graph-endpoints.ts). Search functions kept in sync with mcp-connectwise-psa's advanced.ts

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.
