Tools

The MCP server exposes tools organised into three groups. Groups are loaded or omitted as a whole — you cannot enable or disable individual tools within a group. All three groups are enabled by default; use the LLMBASE_MCP_TOOLS environment variable to restrict which groups are loaded.

Tool groups

Friendly name	Group key	Tools	Data source
Documentation search	collections	search_python-docs, search_python-examples, search_cloud_coverage, search_sql-docs	Vector-indexed docs (pgvector)
Query Based	queries	search_symbol_universe	Live OneTick WebAPI query
Reference data	csv	list_databases, db_tables, db_table_schemas, db_field_descriptions, db_field_enumerations, calendar_holidays, trading_hours	Flat text files in CSV_DATA_PATH

See Documentation Search Tools, Symbol Universe Tool, and Reference Data Tools for a description of each individual tool and when to use it.

Enabling and disabling tool groups

Set LLMBASE_MCP_TOOLS to a comma-separated subset to disable groups you don’t need.

For example, if you do not have OneTick WebAPI credentials, omit the symbol universe group to get started without it:

LLMBASE_MCP_TOOLS=collections,csv

You can add it later once credentials are available. See OneTick WebAPI authentication for the full auth configuration.

Bringing your own data

The pre-configured tools reflect an OneTick Cloud setup. Both the documentation search index and the reference data can be replaced or extended for other deployments:

• Documentation search — register additional collections (document sets) that are indexed and exposed as new search_* tools alongside the built-in ones. See Custom Search Tools.

• Reference data — replace the bundled CSV files by pointing CSV_DATA_PATH at your own directory. See Reference Data Tools.
