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 | $0.01883 | $0.01883 |
| Opus 5 | $0.00941 | $0.00941 |
| Sonnet 5 | $0.00377 | $0.00377 |
| Haiku 4.5 | $0.00188 | $0.00188 |
Grade A, and why
tableau-mcp-apps-lab AGENTS.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 8d 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.
This is a copy
100% identical to tableau-mcp AGENTS.md — 0 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 — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Repo-level contract for the global agent OS. Defines what "correct" means in tableau-mcp. Source of truth for agents before any implementation.
Staged copy. Target path on apply: repo root
AGENTS.md(branchfeature/authoring, ormain). Encodes the canonical Desktop-tool migration pattern verified from merged PRs #347 (session) and #370 (workbook).
Project overview
@tableau/mcp-server — an MCP server "helping agents see and understand data." Exposes Tableau capabilities to MCP clients over stdio and HTTP. Ships multiple build variants (default web, desktop, combined) from one codebase via src/scripts/build.ts + esbuild conditional bundling. An active migration on feature/authoring ports Tableau Desktop authoring tools from the agent-to-tableau-desktop repo into src/tools/desktop/.
Architecture
- Entry:
src/index.tsselects stdio vs HTTP transport (src/transports.ts) byTRANSPORT. - Web server:
src/server.web.ts+src/server/express.ts(WebMcpServer); web tools insrc/tools/web/. - Desktop server:
src/server.desktop.ts(DesktopMcpServer); discovers local Tableau Desktop via@modelcontextprotocol/ext-apps+DesktopDiscoverer; proxies throughDesktopToolExecutor. Desktop tools insrc/tools/desktop/. - SDK layer:
src/sdks/tableau/wraps the Tableau REST API (Zodios). - Cross-cutting:
src/config.ts(auth: pat/uat/direct-trust/oauth),src/logging/(PAT/token masking),src/telemetry/,src/server/oauth/,src/sessions.ts,src/errors/mcpToolError.ts.
Package manager
npm (lockfile package-lock.json). Node >=22.7.5 (engines). Do not switch package managers; do not commit a non-npm lockfile.
Commands
- Install:
npm ci(do not run inside an agent loop unless explicitly asked; never auto-install) - Build:
npm run build(esbuild via tsx; does not typecheck) - Test (all, CI-safe):
npx vitest run --config ./vitest.config.ts— never barenpm test(that is watch mode and hangs) - Test (single file):
npx vitest run src/path/to/file.test.ts - Test (by name):
npx vitest run src/path/to/file.test.ts -t "pattern" - Typecheck:
npx tsc --noEmit(notypechecknpm script exists; build uses esbuild, so this is the only static type gate) - Lint:
npm run lint(eslint) - Canonical check:
scripts/agent-check
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.
