Do I need to install anything to use Index One?

No. Index One is published as a hosted endpoint, so a compatible client connects to it over the network.

How do I install Index One?

Point your client at the hosted endpoint https://api.indexone.io/mcp. No local install is needed.

Which transport does Index One use?

Streamable http. Your client has to support that transport to connect.

Where is the source code for Index One?

The publisher lists https://github.com/index1one/indexone-mcp as the source repository.

Is Index One an official server?

It is published under the namespace io.indexone, which means the publisher proved control of that domain when registering. That confirms who published it, not that it has been reviewed for quality or security.

Which version of Index One is listed here?

Version 1.4.0, taken from the latest registry entry.

Index One MCP server

Name: Index One

Tools

22 tools, from the publisher's manifest. A parameter marked with an asterisk is required. By intent: 18 answer and 4 act.

Intent says what a tool does with the world. Answer reads and returns information and changes nothing. Act changes state somewhere, by writing, creating, sending or deleting. Transact moves money, buys something or commits to a cost. A value marked declared is the publisher's own annotation on their own tool. A value marked inferred is this catalogue reading the tool name and description, and is not a claim by the publisher. Where neither settles it, the tool is left unclassified rather than guessed at.

Tool	What it does	Intent	Parameters
list_operations	List available pipeline operations (id, name, description, category). Call with no args to see all + the category list; pass a category to narrow. Use this to discover real operations instead of guessing.	answer inferred	category
get_operations	Get the full parameter schema and output shape for specific operations. Always fetch an operation's spec before using it so parameters are correct.	answer inferred	operation_ids
list_examples	List production-tested example pipelines (id/name/description). Optional substring search.	answer inferred	search
get_example	Fetch one or MORE example pipelines to learn correct wiring. Pass several ids in 'example_ids' to fetch them in a SINGLE call (cheaper than separate calls) — useful when the index combines patterns from different examples. Each returned example carries 'index_parameters_json' (a JSON string of the full pipeline).	answer inferred	example_id, example_ids
list_workflows	List live workflows. scope='team' (the user's), 'public' (public/featured), or 'all'. Use to build off or repair an existing workflow/index.	answer inferred	limit, scope, search
get_workflow	Fetch one workflow by id. Returns id/name/operation_ids plus 'workflow_json' (a JSON string of the full workflow's index_parameters, including its operations).	answer inferred	workflow_id
list_datasets	List the user's team datasets (id/name/description). Never invent dataset ids — use these.	answer inferred	none
inspect_dataset	Inspect a team dataset's real data. view='schema' (columns+dtypes), 'sample' (rows), 'shape', 'unique' (distinct values of 'column'), or 'stats' (per-column distribution summary). Use before filtering on it.	answer inferred	view, limit, column, dataset_id, sample_rows
run_pipeline	Run a single operation, sub-pipeline, or full workflow in PREVIEW mode (nothing is persisted; source data is real). Returns per-operation state and an output SUMMARY (columns, shape, small sample). Use it to test that a step works and to discover the real columns an operation produces, then inspect_run / get_column_values on the result.	act inferred	note, operations
inspect_run	Introspect a cached run_pipeline output. view='schema'\|'sample'\|'shape'\|'unique'\|'stats'. For 'unique' pass the 'column' (e.g. which sector values exist before filtering). 'stats' returns per-column count/nulls/mean/std/min/quartiles/max — use it to find which factor/score/weight column is skewed or dominates (pass 'column' for one, omit for all). Defaults to the most recent run and, if it has one operation, that operation.	answer inferred	view, limit, op_id, column, run_id, sample_rows
get_column_values	Distinct values of a column — from a dataset (dataset_id) or a cached run (op_id/run_id). The canonical way to discover real filter values (sectors, countries, ratings, ...).	answer inferred	limit, op_id, column, run_id, dataset_id
validate_workflow	Validate a candidate workflow against the manifest. Returns structured issues. Call before submitting.	answer inferred	index_parameters
get_index	Get an index's metadata: name, description, stage/status, calendar settings, value series, and an operation summary. Works for your team's indices and public ones.	answer inferred	index_id
get_index_values	Historical index value series (EOD rows with every value series, e.g. PR/TR). Optional ISO start_time/end_time bounds; long series are evenly downsampled to the point cap, always keeping the latest point.	answer inferred	limit, end_time, index_id, start_time
get_index_holdings	Index holdings snapshot (constituents with shares, weights, divisor) at-or-before 'time' (default: latest). Pass 'limit' for the top-N by weight.	answer inferred	time, limit, index_id
get_index_weightings	Index weighting snapshot at-or-before 'time' (default: latest).	answer inferred	time, index_id
get_index_universe	Index universe snapshot (eligible securities) at-or-before 'time' (default: latest).	answer inferred	time, index_id
get_index_stats	Risk/return summary from the index's EOD value series: cumulative + annualized return, annualized volatility, max drawdown. 'series' picks a value column (default 'value').	answer inferred	series, end_time, index_id, start_time
run_backtest	Run a historical simulation of a workflow (index_parameters JSON). Validates, then launches the run and immediately returns a backtest_id — poll get_backtest until status is 'completed' or 'failed'. Never creates a live index — use deploy_index.	act inferred	end_time, start_time, index_parameters
get_backtest	Fetch a stored backtest result by backtest_id: performance summary and, with include_series=true, the (downsampled) value series. After deploy_index, also reports the deployed live index id.	answer inferred	backtest_id, include_series
save_workflow	Persist a workflow for the caller's team. Without workflow_id: creates a new DRAFT workflow. With workflow_id: updates an owned workflow in place (a live workflow's changed operations trigger a live reload). Always validated first; never changes stage.	act inferred	name, workflow_id, index_parameters
deploy_index	Create a LIVE index from a saved workflow_id or inline index_parameters: runs a full backtest, persists its history, and registers the index for continuous scheduled calculation. Requires confirm=true. Returns the pending index_id + backtest_id immediately — poll get_index(index_id) or get_backtest(backtest_id) until the index lands on 'live' or 'failed' (deployed_index_id appears in get_backtest when done).	act inferred	confirm, end_time, start_time, workflow_id, index_parameters

Tool

What it does

Intent

Parameters

list_operations

List available pipeline operations (id, name, description, category). Call with no args to see all + the category list; pass a category to narrow. Use this to discover real operations instead of guessing.

answer inferred

Command line alternative

Could not determine. The available signals were not conclusive enough to say either way, so this is left open rather than guessed.
