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 | $0.00455 | $0.00455 |
| Opus 5 | $0.00228 | $0.00228 |
| Sonnet 5 | $0.00091 | $0.00091 |
| Haiku 4.5 | $0.00046 | $0.00046 |
Grade A, and why
tldraw-mcp-server 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 10d 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.
What it actually says
tldraw MCP Server — Developer Guide
Build & Run
npm run build # Compiles TypeScript → dist/
npm start # Runs the MCP server (stdio transport)
Architecture
- Entry:
src/index.ts— creates the MCP server, connects stdio transport - Tool registration:
src/register-tools.ts— registers all 30+ tools with the MCP SDK - State:
src/state/document-state.ts— singletonDocumentStatethat holds the in-memory tldraw document (records, pages, shapes, bindings) - Tools:
src/tools/— one file per category (document, shapes-*, connections, manipulation, grouping, ordering, pages, query, camera, assets) - Schemas:
src/schemas/— Zod schemas for shape props and shared styles - Utils:
src/utils/— ID generation, fractional indices, rich text conversion, default props, response helpers
Key Patterns
- Tool registration: Each tool file exports a function that takes the MCP
Serverinstance and callsserver.tool(name, schema, handler). - State management: All tools operate on the shared
statesingleton (imported fromdocument-state.ts). The state holds a flat map of tldraw records. - Shape creation: Tools use
createShapeId()for IDs,getIndexAbove()for z-ordering indices, andgetDefault*Props()for base shape properties. - Rich text: tldraw uses a custom rich text format. Use
textToRichText(plainString)to convert plain text. - Arrow bindings: Created as separate
bindingrecords that link an arrow's terminal (start/end) to a target shape.
File Naming Conventions
shapes-*.ts— one file per shape type (geo, text, arrow, note, frame, draw, line, image, video, bookmark, embed, highlight)- Tool names use
tldraw_prefix with snake_case (e.g.,tldraw_create_geo)
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.
