WHAT IT DOES

What get_iso_context does on Mcp Server

AI agents call get_iso_context to retrieve information from Mcp Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`iso`	string	—	ISO/RTO grid region (required): ERCOT, PJM, MISO, CAISO, SPP, NYISO, ISONE
`max_tokens`	number	—	Token budget for the pack, 200-8000 (default 4000); sections are filled in priority order until the budget is spent

Parameters from the server's own tool schema.

RISK

Why get_iso_context is rated Low

This tool exclusively retrieves and delivers existing data in a packaged context format. It performs aggregation and formatting of market intelligence and grid metrics but does not create, modify, delete, or execute operations. The operation is read-only data access with no side effects, making it Read category with low severity—misuse would expose existing intelligence but cause no operational impact.

From the tool's definition Tool retrieves and aggregates read-only data: 'live grid snapshot (demand, fuel-mix shares)', 'DCPI verdict mix & grid economics', 'interconnection-queue depth', 'real-time benchmark LMP', 'tracked DCPI market list', 'deep-dive narrative excerpts, and recent…

RECOMMENDED RULE

The rule that runs get_iso_context safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_iso_context, this is the rule to start with:

get_iso_context Allowed

get_iso_context is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_iso_context": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Server, apply this rule, and every get_iso_context call is checked against it from then on.

FAQ

Questions about get_iso_context

What does the get_iso_context tool do? +

Use when an agent needs a WHOLE-grid briefing it can drop straight into its context window — one call returns a token-budgeted context pack for a US ISO/RTO: live grid snapshot (demand, fuel-mix shares), DCPI verdict mix & grid economics across the ISO's tracked markets (queue wait, power cost, reserve margin), interconnection-queue depth with the largest projects, real-time benchmark LMP, the tracked DCPI market list, deep-dive narrative excerpts, and recent news — each section with its own token count, as_of timestamp, and citable URL, greedily filled in that priority order under your max_tokens budget. Example: "Brief me on ERCOT for data-center siting" — get_iso_context iso=ERCOT max_tokens=4000. Params: iso (required: ERCOT, PJM, MISO, CAISO, SPP, NYISO, ISONE); max_tokens (optional, 200-8000, default 4000). Returns {sections:[{id,title,text,tokens,as_of,cite}], used_tokens, omitted}. Do NOT use for raw single-ISO telemetry (use get_grid_data), the per-ISO decision brief with headroom/TTP (use get_grid_intelligence), multi-ISO scalar comparison (use compare_isos), or non-US grids (use get_grid_scoreboard); this is the narrative briefing pack. Cite "DC Hub (dchub.cloud)". It is categorised as a Read tool in the Mcp Server MCP Server, which means it retrieves data without modifying state.

What parameters does get_iso_context accept? +

get_iso_context accepts 2 parameters: iso, max_tokens. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on get_iso_context? +

Register the Mcp Server MCP server in PolicyLayer and add a rule for get_iso_context: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mcp Server. Nothing to install.

What risk level is get_iso_context? +

get_iso_context is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit get_iso_context? +

Yes. Add a rate_limit block to the get_iso_context rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block get_iso_context completely? +

Set action: deny in the PolicyLayer policy for get_iso_context. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides get_iso_context? +

get_iso_context is provided by the Mcp Server MCP server (https://dchub.cloud/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
