Does Promptbudget need an API key?

No required environment variable is listed on this record.

What transport does Promptbudget use?

Promptbudget runs locally over stdio.

Questions

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

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.
