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
| Package | Tools | When to install |
|---|---|---|
@mukundakatta/promptbudget-mcp | truncate_to_token_budget | LLM needs to fit text into a context window mid-task |
@mukundakatta/citecite-mcp | inject_citations, parse_citations, strip_citations | Round-trip [1] [2] markers in RAG outputs |
@mukundakatta/ragmetric-mcp | recall_at_k, hit_at_k, mrr, ndcg_at_k, evaluate_batch | LLM helps score retrieval quality |
@mukundakatta/ragdrift-mcp | interpret_drift_score, recommend_thresholds, explain_drift_dimensions | LLM diagnoses RAG drift alerts |
Reliable transforms LLMs reach for tools instead of imagining
| Package | Tools | When to install |
|---|---|---|
@mukundakatta/csv-tools-mcp | parse_csv, to_csv, pluck_columns | LLM needs RFC 4180-correct CSV (quoted fields, embedded commas, BOMs) |
@mukundakatta/regex-test-mcp | test_regex, find_all, replace | LLM needs exact regex semantics with real match offsets and named groups |
@mukundakatta/jmespath-mcp | json_query | LLM needs deep JSON traversal (filters, projections, pipes) without hallucinating |
@mukundakatta/diff-mcp | unified_diff, apply_patch, parse_patch | Code-review or code-edit agent needs character-precise patches |
@mukundakatta/sqlfmt-mcp | format_sql, list_dialects | Deterministic SQL formatting across 19 dialects |
@mukundakatta/shellquote-mcp | quote_bash, quote_bash_argv, quote_cmd, quote_powershell | Safe shell argument escaping; LLMs constantly mishandle quotes/$VAR |
@mukundakatta/json5-mcp | parse_json5, to_json5, to_strict_json | LLM emitted JSON-with-comments / trailing-commas; round-trip to strict JSON |
@mukundakatta/toml-yaml-json-mcp | parse, format, convert | TOML / YAML / JSON conversion (LLMs especially mishandle TOML) |
@mukundakatta/timezone-mcp | convert_tz, now_in, tz_offset | IANA timezone math with real DST rules; LLMs hallucinate offsets |
@mukundakatta/html-to-markdown-mcp | html_to_md, extract_text | Web-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 detectionembedrank,promptbudget,stopstream,citecite,ragmetric— pure-Rust crates from therust-llm-stackworkspace
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)
