Summary

Exposes three timezone tools,convert_tz, now_in, and tz_offset,that use the full IANA timezone database with real DST transitions. Useful when your agent or RAG pipeline needs to handle "America/New_York" or "Europe/London" conversions without hallucinating offsets or forgetting daylight saving boundaries. Ships as a standalone npm package, no Rust toolchain required. Part of the mcp-stack collection of fourteen small servers that offload transforms LLMs tend to get wrong. Install via npx in Claude Desktop, Cursor, Cline, Windsurf, or any stdio MCP client.

mcp-stack

Fourteen small MCP servers for everyday LLM / RAG / agent work. Each ships independently on npm, listed in the official MCP Registry, and is callable from Claude Desktop, Cursor, Cline, Windsurf, Zed, and any other MCP-compatible client.

RAG / agent helpers

PackageToolsWhen to install
@mukundakatta/promptbudget-mcptruncate_to_token_budgetLLM needs to fit text into a context window mid-task
@mukundakatta/citecite-mcpinject_citations, parse_citations, strip_citationsRound-trip [1] [2] markers in RAG outputs
@mukundakatta/ragmetric-mcprecall_at_k, hit_at_k, mrr, ndcg_at_k, evaluate_batchLLM helps score retrieval quality
@mukundakatta/ragdrift-mcpinterpret_drift_score, recommend_thresholds, explain_drift_dimensionsLLM diagnoses RAG drift alerts

Reliable transforms LLMs reach for tools instead of imagining

PackageToolsWhen to install
@mukundakatta/csv-tools-mcpparse_csv, to_csv, pluck_columnsLLM needs RFC 4180-correct CSV (quoted fields, embedded commas, BOMs)
@mukundakatta/regex-test-mcptest_regex, find_all, replaceLLM needs exact regex semantics with real match offsets and named groups
@mukundakatta/jmespath-mcpjson_queryLLM needs deep JSON traversal (filters, projections, pipes) without hallucinating
@mukundakatta/diff-mcpunified_diff, apply_patch, parse_patchCode-review or code-edit agent needs character-precise patches
@mukundakatta/sqlfmt-mcpformat_sql, list_dialectsDeterministic SQL formatting across 19 dialects
@mukundakatta/shellquote-mcpquote_bash, quote_bash_argv, quote_cmd, quote_powershellSafe shell argument escaping; LLMs constantly mishandle quotes/$VAR
@mukundakatta/json5-mcpparse_json5, to_json5, to_strict_jsonLLM emitted JSON-with-comments / trailing-commas; round-trip to strict JSON
@mukundakatta/toml-yaml-json-mcpparse, format, convertTOML / YAML / JSON conversion (LLMs especially mishandle TOML)
@mukundakatta/timezone-mcpconvert_tz, now_in, tz_offsetIANA timezone math with real DST rules; LLMs hallucinate offsets
@mukundakatta/html-to-markdown-mcphtml_to_md, extract_textWeb-scraping agents need clean Markdown / text from HTML

Sibling libraries

The first four wrap or re-implement logic from the user's Rust + Python work:

  • ragdrift (crates.io) / ragdrift-py (PyPI) — five-dimensional drift detection
  • embedrank, promptbudget, stopstream, citecite, ragmetric — pure-Rust crates from the rust-llm-stack workspace

The MCP servers are independent: they implement the logic they need in plain JavaScript so installing them doesn't pull a Rust toolchain.

Install (any of them)

Add to your MCP client config. Example for Claude Desktop:

{
  "mcpServers": {
    "promptbudget": { "command": "npx", "args": ["-y", "@mukundakatta/promptbudget-mcp"] },
    "citecite":     { "command": "npx", "args": ["-y", "@mukundakatta/citecite-mcp"] },
