add_sourceAdd a source to a channel and begin background ingestion.No findings
Why it is in this group
- The name "add_source" says "add": a word for a change.
Description, as the server wrote it
Add a source to a channel and begin background ingestion. Maps to POST /v1/channels/{channelId}/sources. Only `type: video` is processed today; `document` and `website` are reserved and return a 501 error until released. Requires the key's `write` scope.
Annotations the server declares
- title: Add a source to a channel
- readOnlyHint: false
- openWorldHint: true
add_sourcesCharged like `transcribe`.No findings
Why it is in this group
- The name "add_sources" says "add": a word for a change.
Description, as the server wrote it
Charged like `transcribe`. Expand the given YouTube URLs, charge for the new work and start an ingest job in an existing collection. Maps to POST /v1/collections/{collectionId}/sources. $0.01/min standard, $0.03/min whisper by default, 1-minute minimum per video. Videos already in the collection are free. Pass a `quote_id` from `quote` to be charged exactly that price. Poll `get_status` every 10–30 s until `status` is completed, partial or failed; `completed` means every accepted video is transcribed and indexed, so the collection is queryable. API key required (the key's `write` scope). Prices are the service defaults; `quote` returns the exact price.
Annotations the server declares
- title: Add YouTube sources to a collection
- readOnlyHint: false
- openWorldHint: true
create_collectionFree.No findings
Why it is in this group
- The name "create_collection" says "create": a word for a change.
Description, as the server wrote it
Free. Create an empty collection to add sources to later with `add_sources`. Maps to POST /v1/collections. Returns the collection and its `collection_token` (`ct_…`, shown once: store it; absent on an idempotent replay). API key required (the key's `write` scope). Prices are the service defaults; `quote` returns the exact price.
Annotations the server declares
- title: Create an empty collection
- readOnlyHint: false
- openWorldHint: true
query_channelRun a retrieval-augmented query against a channel's indexed knowledge base and return a generated answer with citations.1 finding
Why it is in this group
- The name "query_channel" says "query": a word for reading.
- The description's first verb is "run": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

  The server marks "query_channel" read-only (readOnlyHint: true), and its own name, description or input give the class "write".
  Matched text
  annotations: {"readOnlyHint":true,"openWorldHint":true}; The name "query_channel" says "query": a word for reading.
  What this check looks for
Description, as the server wrote it
Run a retrieval-augmented query against a channel's indexed knowledge base and return a generated answer with citations. Maps to POST /v1/query. Requires the key's `query` scope and access to the channel. Charged: $0.02 flat per call by default. Prices are the service defaults; `quote` returns the exact price.
Annotations the server declares
- title: Query a channel
- readOnlyHint: true
- openWorldHint: true
quoteFree.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Free. Expand YouTube URLs exactly as an ingest would and return the price, the per-video lines and the per-source rejections. Maps to POST /v1/quote. $0.01/min standard, $0.03/min whisper by default, 1-minute minimum per video. The `quote_id` is valid for 15 minutes; pass it to `transcribe` or `add_sources` to be charged exactly this price. Pass `collection_id` to price against an existing collection (videos already in it are free). At least one of url, urls, channel_url, channel_urls. Requires the key's `read` scope. Prices are the service defaults; `quote` returns the exact price.
Annotations the server declares
- title: Quote an ingest
- readOnlyHint: true
- openWorldHint: true
transcribeCharged.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
Charged. Create a collection and start an ingest job for the given YouTube URLs in one call. Maps to POST /v1/transcribe. $0.01/min standard, $0.03/min whisper by default, 1-minute minimum per video. Pass a `quote_id` from `quote` to be charged exactly that price. Returns `job_id`, `collection_id` and `collection_token` (`ct_…`, shown once: store it; it reads this collection without an API key). Poll `get_status` every 10–30 s until `status` is completed, partial or failed; `completed` means every accepted video is transcribed and indexed, so the collection is queryable. With an API key it needs the key's `write` scope. Without an API key this tool is payable in USDC via x402: the first call returns a payment-required result (`isError` with the payment requirements in `structuredContent`); an x402-aware MCP client signs and retries the same call with `_meta['x402/payment']`, and the receipt returns in the result's `_meta['x402/payment-response']`. Never pay again after a 409 (already presented) or 502 (settlement unknown) result. Keyless `transcribe` takes one channel-like source and at most 3 videos. Prices are the service defaults; `quote` returns the exact price.

- title: Transcribe into a new collection

get_sourceFetch a single source and its processing status (type-specific provenance included).No findings
Why it is in this group
- The name "get_source" says "get": a word for reading.
Description, as the server wrote it
Fetch a single source and its processing status (type-specific provenance included). Maps to GET /v1/sources/{sourceId}. Requires the key's `read` scope.
Annotations the server declares
- title: Get a source
- readOnlyHint: true
- openWorldHint: true
get_statusFree.No findings
Why it is in this group
- The name "get_status" says "get": a word for reading.
Description, as the server wrote it
Free. Get an ingest job started by `transcribe` or `add_sources`. Maps to GET /v1/jobs/{jobId}. Poll every 10–30 s until `status` is completed, partial or failed (terminal). `completed` means every accepted video is transcribed and indexed, so the collection is queryable; `partial` means some videos failed and were credited back (`credited_usd`); `videos.completed` / `videos.failed` count progress. Works with an API key or the collection's `ct_` token as the bearer. Prices are the service defaults; `quote` returns the exact price.
Annotations the server declares
- title: Get an ingest job
- readOnlyHint: true
- openWorldHint: true
get_transcriptFree.No findings
Why it is in this group
- The name "get_transcript" says "get": a word for reading.
Description, as the server wrote it
Free. Get the transcript of a video that is completed in one of your collections. Maps to GET /v1/videos/{youtubeId}/transcript. `collection_id` is required with an API key; with the collection's `ct_` token as the bearer it defaults to the token's collection. `format` is json (segments with timestamps, default) or text (one `[H:MM:SS] text` line per segment). 404 when the video is not completed in that collection, or the transcript predates the transcript cache. Prices are the service defaults; `quote` returns the exact price.
Annotations the server declares
- title: Get a video's transcript
- readOnlyHint: true
- openWorldHint: true
get_usageGet usage, quota, and spend for the calling key (queries, tokens, cost, budget remaining).No findings
Why it is in this group
- The name "get_usage" says "get": a word for reading.
Description, as the server wrote it
Get usage, quota, and spend for the calling key (queries, tokens, cost, budget remaining). Maps to GET /v1/usage. Requires the key's `read` scope.
Annotations the server declares
- title: Get usage and spend
- readOnlyHint: true
- openWorldHint: true
list_channelsList the channels the calling key is scoped to.No findings
Why it is in this group
- The name "list_channels" says "list": a word for reading.
Description, as the server wrote it
List the channels the calling key is scoped to. Maps to GET /v1/channels. Cursor-paginated. Requires the key's `read` scope.
Annotations the server declares
- title: List channels
- readOnlyHint: true
- openWorldHint: true
list_sourcesList the sources (video/document/website) in a channel, optionally filtered by type or status.No findings
Why it is in this group
- The name "list_sources" says "list": a word for reading.
Description, as the server wrote it
List the sources (video/document/website) in a channel, optionally filtered by type or status. Maps to GET /v1/channels/{channelId}/sources. Cursor-paginated. Requires the key's `read` scope.
Annotations the server declares
- title: List sources in a channel
- readOnlyHint: true
- openWorldHint: true
query_collectionCharged: $0.02 flat per call by default, no token multiplier.No findings
Why it is in this group
- The name "query_collection" says "query": a word for reading.
Description, as the server wrote it
Charged: $0.02 flat per call by default, no token multiplier. Ask a question of a collection and get a generated answer with citations. Maps to POST /v1/collections/{collectionId}/query. Query a collection once `get_status` says completed. With an API key it needs the key's `query` scope. Without an API key this tool is payable in USDC via x402: the first call returns a payment-required result (`isError` with the payment requirements in `structuredContent`); an x402-aware MCP client signs and retries the same call with `_meta['x402/payment']`, and the receipt returns in the result's `_meta['x402/payment-response']`. Never pay again after a 409 (already presented) or 502 (settlement unknown) result. Keyless, only the address that paid for the collection may query it. Prices are the service defaults; `quote` returns the exact price.
Annotations the server declares
- title: Query a collection
- readOnlyHint: true
- openWorldHint: true

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

6 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
