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 | $0.00602 | $0.00602 |
| Opus 5 | $0.00301 | $0.00301 |
| Sonnet 5 | $0.00120 | $0.00120 |
| Haiku 4.5 | $0.00060 | $0.00060 |
Grade A, and why
valtown-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 9d 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.

About ValTown
ValTown is a serverless platform for running TypeScript/JavaScript code in the cloud. Key concepts for developers:
- Vals: Code snippets that can be HTTP endpoints, scheduled functions, or scripts
- HTTP Vals: Functions that handle HTTP requests (similar to serverless functions)
- Interval Vals: Functions that run on a schedule (like cron jobs)
- Script Vals: One-time or manually triggered functions
- Email Vals: Functions that handle incoming emails
- API Integration: Full REST API for programmatic access to create/update/delete vals
- Remote Execution: Code runs in ValTown's sandboxed environment with built-in npm package support
Architecture Overview
This is a Model Context Protocol (MCP) server that provides AI assistants with access to ValTown's platform. The codebase supports two deployment modes:
- Local Binary Mode (
mod.ts): Runs as a local MCP server using stdio transport - Remote HTTP Mode (
index.http.ts): Deployed on ValTown itself as an HTTP endpoint, accessible via streamable HTTP transport
The server is hosted remotely on ValTown at: https://prashamtrivedi-valtown-mcp-server.val.run/mcp
Key files:
mod.ts: Local stdio MCP server entry pointindex.http.ts: Remote HTTP MCP server entry point (deployed on ValTown)registerTools.ts: Tool registration with CLI exclusion support for remote deploymentconfig.ts: Configuration loading with remote/local mode support
Commands
- Run server locally:
deno task start - Development mode:
deno task dev - Build binaries:
deno task build - Platform-specific builds:
deno task build:linux,deno task build:windows,deno task build:macos
Style Guidelines
- Use TypeScript strict mode with explicit typing for function parameters/returns
- 2-space indentation, semicolons at line ends
- Use camelCase for variables/functions, PascalCase for types/interfaces, UPPER_SNAKE_CASE for constants
- Tool names use kebab-case (e.g.,
get-val) - Document all public functions with JSDoc
- Wrap async operations in try/catch blocks and use getErrorMessage utility
- Return consistent error responses with isError flag
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.

valtown-mcp-server CLAUDE.md is an instructions file published in the GitHub repository PrashamTrivedi/valtown-mcp-server (15 stars, last pushed 1y ago), licensed MIT. It adds 602 tokens to every session, about $0.0030 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
