Use viaNexus vAST safely with AI agents

Guidance for connecting the viaNexus vAST financial data connector: confirm the account and dataset scope, pick the right tool, and handle entitlement blocks. The agent asks before changing any access rule.

Use it when

  • You have just connected viaNexus vAST and want to know what it can reach
  • A financial answer needs to respect which datasets your subscription includes
  • You are about to change an access rule and want it reviewed first

Tools it uses

  • get_rule
  • current_date
  • search
  • fetch
  • create_rule
  • delete_rule
Example

Connect to viaNexus and tell me what I can query before we start on the Q3 numbers.

Your sign-in covers the core market data family and the premium newswire family. A rule on this account excludes the premium family, so searches there will come back blocked. I checked the current date first, so 'latest' means the last trading session. I have not changed any access rule; if you want the premium family enabled, I can draft that change for your approval.

Audit viaNexus vAST dataset permissions

Reviews the dataset access rules on a viaNexus vAST account against the access you intend, flags rules that are too broad, too narrow or missing, and proposes changes. It asks before creating or deleting any rule.

Use it when

  • Checking whether an agent can reach datasets it should not
  • Tightening wildcard rules after new datasets were added
  • Finding stale single-dataset rules left from an old project

Tools it uses

  • get_rule
  • create_rule
  • delete_rule
Example

Audit our vAST rules. The research agent should see market data and news, but not partner datasets.

I read 6 rules on the research scope. Market data and news match your intent. One wildcard include (EDGE:*) grants 2 partner datasets you want blocked, so I propose adding an exclude for EDGE:PARTNER* and a narrower include. Nothing is changed yet. Shall I create the exclude rule?

Look up financial data with viaNexus vAST

Answers a financial data question by searching the viaNexus catalog, fetching only the rows you are entitled to, and reporting the source, as-of date and coverage gaps. It asks before changing any account permissions.

Use it when

  • You need a price, fundamental or reference figure from licensed data
  • You want to know which dataset holds a measure before quoting it
  • You need to know whether a gap is missing data or a permission block

Tools it uses

  • current_date
  • search
  • get_rule
  • fetch
  • create_rule
  • delete_rule
Example

What was ACME Corp's latest quarterly revenue, and which dataset is it from?

ACME Corp reported quarterly revenue of 4.2 billion USD for the period ending 31 March, from the fundamentals dataset, as of 12 May. The series has 8 quarters with no gaps in revenue, but the prior-year quarter is marked preliminary. I did not check the European news dataset because your current rules exclude it.

How viaNexus vAST skills work

  1. Connect viaNexus vAST

    The viaNexus vAST MCP server gives the agent its tools.

  2. Ask in plain words

    “Audit our vAST rules. The research agent should see market data and news, but not partner datasets.” Each SKILL.md says when it applies, so only the one that fits is loaded.

  3. Approve any change

    The agent calls the tools in order, checks its work, and shows you any change before it makes it.

How to install viaNexus vAST skills

In RevampKey the skills install themselves when you connect viaNexus vAST. In other tools each skill is one folder with a SKILL.md file, and you also need the viaNexus vAST MCP server connected there.

viaNexus vAST skills FAQ

What is a viaNexus vAST agent skill?

A SKILL.md file: a short playbook an AI agent loads when your request matches it. Each viaNexus vAST skill describes one job, which viaNexus vAST tools to use in which order, what to check first and when to stop and ask you.

Do the viaNexus vAST skills change anything on their own?

The others tell the agent to show you the change and wait for a yes before it creates, edits or deletes anything in viaNexus vAST.

Which tools can use these skills?

Any agent that reads the open Agent Skills format: Claude Code, Cursor, Codex, VS Code with Copilot and RevampKey. In RevampKey they are attached when you connect viaNexus vAST; elsewhere you copy the folders into your project or skills directory.

Do I need the viaNexus vAST MCP server too?

Yes. The skills tell the agent how to do the work; the viaNexus vAST MCP server gives it the tools to do it. The viaNexus vAST MCP setup guide covers every client.
