Pinia Colada

4.83 / 5 composite score · 93.9% API recall · 49 questions evaluated

Vue Docs MCP provides deep access to the official Pinia Colada documentation, covering the smart data-fetching layer for Vue: queries, mutations, infinite queries, the query/mutation cache, the defineQuery factory pattern, the official plugin set, and migration paths from TanStack Query (Vue Query).

Pairs with Pinia

Pinia Colada is built on Pinia and shares its devtools and reactivity. Both are always available: call docs_search with framework: "pinia" or framework: "pinia-colada", or use ecosystem_search to search them together.

Usage

Pass framework: "pinia-colada" to docs_search, api_lookup and get_related. No activation is needed: every framework is always available.

Tools

docs_search

Semantic search over Pinia Colada documentation. Uses the standard 6-step retrieval pipeline: embed query, hybrid search (dense + BM25), resolve HyPE hits, expand cross-references, rerank, and reconstruct into readable markdown.

Parameter	Type	Default	Description
framework	string		Always "pinia-colada"
query	string		Developer question or topic (max 2000 chars)
scope	string	"all"	Documentation section to search within
max_results	integer	3	Number of sections to return (1-20)

Scope values: all, guide, advanced, cookbook, plugins

api_lookup

Fast exact-match API reference lookup with fuzzy fallback. Returns type signatures, descriptions, and usage examples directly from the documentation.

Parameter	Type	Default	Description
framework	string		Always "pinia-colada"
api_name	string		API name to look up (e.g. useQuery, defineQuery, useQueryCache, PiniaColadaRetry)

get_related

Find related APIs, concepts, and documentation pages for a given API or topic.

Parameter	Type	Default	Description
framework	string		Always "pinia-colada"
topic	string		API name or concept to explore

Resources

URI	Description
pinia-colada://topics	Full table of contents
pinia-colada://topics/{section}	TOC for a specific section (e.g. pinia-colada://topics/guide)
pinia-colada://pages/{path}	Raw markdown of any doc page (e.g. pinia-colada://pages/guide/queries)
pinia-colada://api/index	Complete API entity index grouped by type
pinia-colada://api/entities/{name}	Details for a specific API (e.g. pinia-colada://api/entities/useQuery)
pinia-colada://scopes	All valid search scope values

Prompts

Prompt	Parameters	Description
debug_issue	framework, symptom, code_snippet (optional)	Systematic debugging workflow: identifies the concept, searches docs, looks up APIs, and provides a fix
compare_apis	framework, items (comma-separated)	Side-by-side comparison of APIs or patterns (e.g. useQuery, defineQuery)
migrate_pattern	framework, from_pattern, to_pattern	Migration guide between patterns (e.g. TanStack Query to Pinia Colada)

Benchmarks vs Context7

Evaluated on 49 Pinia Colada questions scored by an LLM judge (Gemini, temperature 0) across 5 dimensions on a 1-5 scale.

Methodology

Each question has a ground-truth answer with expected API names and documentation paths. Both providers receive the same question and return documentation context. The judge scores the retrieved context on relevance, completeness, correctness, API coverage, and conciseness. See the eval/ directory in the repository for the full evaluation framework.
