Documentation Search Tools

Use the search_* tools to search OneTick documentation by topic or natural language question. Each tool covers a different documentation set; pass a query string and get back the most relevant passages.

Tool descriptions

MCP Tool	When to use
search_python-docs	Search the onetick-py library API reference. Use when looking up classes, methods, parameters, or return types.
search_python-examples	Search practical onetick-py usage examples. Use when looking for how to accomplish a specific task with the library.
search_cloud_coverage	Search OneTick Cloud coverage documentation. Use when checking which exchanges, instruments, or data types are available.
search_sql-docs	Search OneTick SQL documentation. Use when constructing SQL queries or looking up SQL syntax and built-in functions.

Data source

Each search_* tool is backed by a named collection — a document set indexed from a documentation source. OneTick Cloud users get the bundled collections out of the box (see Download documentation sources). For custom deployments, additional collections can be added — see Custom Search Tools.

MCP Tool	Collection name	Content
search_python-docs	python-docs	onetick-py library API docs
search_python-examples	python-examples	Practical usage examples
search_cloud_coverage	cloud	OneTick Cloud coverage docs
search_sql-docs	sql-docs	OneTick SQL documentation

The active set of collections is controlled by the COLLECTIONS setting — see Active collections.

Active collections

The COLLECTIONS setting controls which search_* tools are registered. The default corresponds to the OneTick documentation sources indexed during the quickstart:

COLLECTIONS='["python-docs","python-examples","cloud","sql-docs"]'

To disable individual tools, start from the default and remove the collections you don’t need. For example, to disable sql-docs:

COLLECTIONS='["python-docs","python-examples","cloud"]'

To add your own documentation sources, see Custom Search Tools.
