MCP tool reference

The live list is always tools/list, mirrored byte-for-byte at /.well-known/mcp/server-card.json. This page is the human-readable version of the same surface.

Memory tools

All eight touch a user's private memory and require an OAuth grant.

cortex_ask

Searches the memory, fusing vector, full-text and graph retrieval, and answers with provenance. Scope: memory:read.

Argument	Type	Required
question	string	✓
limit	number	Defaults to 10
source_table	string	Restrict to one source table
since / until	string	RFC 3339 bounds on item time

Read the response carefully. See asking a memory.

cortex_recall

Semantic-only vector search returning source excerpts. Prefer cortex_ask unless you specifically want nearest-neighbour matches on meaning. Scope: memory:read.

Argument	Type	Required
query	string	✓
limit	number	Defaults to 10

cortex_manifest

An index of the memory: counts and source names, never content. Takes no arguments. Scope: memory:read.

cortex_status

Ingestion and feed status, including backlog. Use it to explain why a freshly-connected source is not answering yet. Scope: memory:read.

cortex_connectable_sources

Lists sources the user has not connected, and what each would answer. No arguments. Scope: memory:read.

cortex_connect_link

Returns the connect link for one source. Scope: memory:read.

Argument	Type	Required
source_id	string	✓. For example google-workspace, github, notion
link_text	string	Link text in the user's own words

cortex_remember

Saves one durable fact into the graph. Scope: memory:write.

Argument	Type	Required
text	string	✓
kind	string	e.g. decision, observation, task-outcome
confidence	number	0..1
source_universal_ids	string[]	Ids from a prior cortex_ask

cortex_ingest_conversation

Ingests a whole conversation so the exchange itself becomes retrievable. Scope: memory:write.

Search and fetch

Present for clients that expect the search / fetch pair. ChatGPT in particular refuses a server whose search and fetch it cannot see.

Tool	Required argument	What it does
search	query	Searches the user's memory
fetch	id	Retrieves one item in full by its universal id

Public tools

No credential. Safe to call before any sign-in, and useful as a connectivity check.

Tool	Required argument	What it returns
get_pricing	none	Current plans, prices, credit allowances, metered rates, add-ons
get_platform_status	none	Operational status of the website, API and MCP server
search_docs	query	Ranked documentation and product-page results with URLs
list_skills	none	Published agent skills, with links
