MCP Server
Spark - AI Assets Marketplace
io.github.entire-vc/spark
What this MCP does
Searches an AI asset marketplace and retrieves details or content for agents, skills, prompts, MCP connectors, and related bundles.

get_asset
Get asset details
Get full details of a Spark asset by its slug â description, metadata, outcome
reports, bundled files and the URL on spark.entire.vc.
Takes a slug, for example from a search result, a popular list or a link. Returns
the full picture of the asset. It does not return the prompt/skill/agent text
itself; get_asset_content returns that.

Input schema
{'type': 'object', 'required': ['slug'], 'properties': {'slug': {'type': 'string', 'description': "Asset slug (e.g. 'vb-seo-expert', 'vb-python-expert')"}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'required': ['result'], 'properties': {'result': {'type': 'string'}}, 'x-fastmcp-wrap-result': True}
get_asset_content
Get asset content
Get the raw content of a Spark asset (prompt text, skill instructions, agent config) â
the actual text to apply, not just a description of it.
Takes a slug. Unlike search_assets and get_asset, this counts as a download/acquisition
event, and each call may return different content if the asset was updated. Paid
assets require authentication: a Spark API key (X-API-Key header) or a Bearer token
in the MCP client configuration. The response ends with an `application_id` line that
identifies this fetch; report_outcome takes it as its `application_id` argument.
Input schema
{'type': 'object', 'required': ['slug'], 'properties': {'slug': {'type': 'string', 'description': 'Asset slug'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'required': ['result'], 'properties': {'result': {'type': 'string'}}, 'x-fastmcp-wrap-result': True}
list_categories
List categories
List available categories (domains and AI tags) in the Spark marketplace.
Returns the domain slugs that search_assets accepts as its `domain` filter, and the
AI tags, as a taxonomy of the catalog.
Example: list_categories()

Idempotent
Input schema
{'type': 'object', 'properties': {}, 'additionalProperties': False}
Output schema
{'type': 'object', 'required': ['result'], 'properties': {'result': {'type': 'string'}}, 'x-fastmcp-wrap-result': True}
list_popular
List popular assets
List the most popular Spark assets by download count, optionally filtered by type.
Takes no search text; it returns the current top of the catalog by downloads.
Read only
Idempotent
Input schema
{'type': 'object', 'properties': {'type': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'default': None, 'description': 'Filter by asset type (agent, skill, prompt, prompt_chain, mcp_connector, bundle)'}, 'limit': {'type': 'integer', 'default': 10, 'description': 'Number of results (1-20, default 10)'}}, 'additionalProperties': False}
Output schema
{'type': 'object', 'required': ['result'], 'properties': {'result': {'type': 'string'}}, 'x-fastmcp-wrap-result': True}
report_outcome
Report outcome
Records the result of applying an asset that was fetched with get_asset_content: applied as is, applied with changes, broke, or not applicable. The report is tied to the application_id that get_asset_content returned; submitting the same application_id again updates the report. Reports made with an API key are counted; anonymous ones are stored as unverified.
Fields `task`, `note`, `changed_what`, `failed_at`, `expected`, `got` are published on the asset's public page on spark.entire.vc, visible to any visitor. Do not include client data, private paths, keys, emails or URLs with tokens. Your identity is never shown on that page.
Example: report_outcome(application_id='<from get_asset_content>', result='applied_with_changes', task='add a rate limiter to the API', changed_what='swapped the fixed window for a token bucket').

Shown, never ranked.'}, 'result': {'enum': ['applied_as_is', 'applied_with_changes', 'broke', 'not_applicable'], 'type': 'string', 'description': 'applied_as_is: applied without edits, task solved. applied_with_changes: had to edit it, then solved (requires changed_what). broke: tried to apply and it failed (requires failed_at). not_applicable: read it and did not apply, it does something else (requires expected and got).'}, 'expected': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'default': None, 'description': 'not_applicable: what you were looking for (â\x89¤ 200).'}, 'failed_at': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'default': None, 'description': 'broke: the step, tool or command that failed, and the error class (â\x89¤ 200).'}, 'changed_what': {'anyOf': [{'type': 'string'}, {'type': 'null'}], 'default': None, 'description': 'applied_with_changes: what you changed (â\x89¤ 200).'}, 'application_id': {'type': 'string', 'description': 'The application_id at the end of the get_asset_content response.'}}, 'additionalProperties': False}

search_assets
Search assets
Search the Spark AI assets marketplace for agents, skills, prompts, prompt chains, MCP connectors and bundles.
Finds assets by text query, for when the slug is not known. Returns a numbered
list of short summaries: title, type, downloads, outcome summary, price, tags and
the asset's URL on spark.entire.vc.
