REST Surface

MCP Surface

Local MCP Setup

Some MCP clients launch servers from the user's home directory or ignore a configured cwd. Use uv run --directory so the server always starts from the repository project.

{
  "command": "uv",
  "args": [
    "run",
    "--directory",
    "/absolute/path/to/OSINT",
    "python",
    "-m",
    "core.mcp_server"
  ]
}

Leave EXASCALE_PARQUET_BASE / EXASCALE_RAW_BASE unset: the one server hosts every data point's tools, and with no override it resolves each block's promoted snapshots and raw archive from the repository layout. Setting either env var points ALL tools at one directory — a per-block path breaks every other block's tools. They exist only for single-source sandboxes and tests.

Metric metadata:

Metric Category Unit Aggregation Additive Across Groups Authoritative Total Definition
net_mw requested_mw MW sum true summary.totals.net_mw The project's net megawatts (0 for CNR-only requests), as ISO-NE reports it (Net MW).
summer_mw requested_mw MW sum true summary.totals.summer_mw The project's maximum summer megawatt output, as ISO-NE reports it (Summer MW).
winter_mw requested_mw MW sum true summary.totals.winter_mw The project's maximum winter megawatt output, as ISO-NE reports it (Winter MW).
source_record_count records count count source records true summary.totals.source_record_count Count of ISO-NE queue table-rows in the current result scope (one atom = one row of the rendered public-queue report).

Field Coverage Codes Examples Note
application_status the distinct application_status codes served from the ISO-NE snapshot 3 A = Active — a live request still in the queue (requested, not built), C = Commercial — the project is built and in service (the built reading), W = Withdrawn — the request left the queue (the queue is withdrawn-dominated) ALWAYS scope by application_status — the queue is dominated by Withdrawn requests. A is the live pipeline of REQUESTED (not built) capacity; C is Commercial (built and energized); W left the queue. A queue-MW total is requested capacity, never built — for built/operating capacity use query_power_capacity_v1. This is SEPARATE from project_status (build progress).
request_type the distinct request types served from the ISO-NE snapshot 3 G = Generation interconnection request, ETU = Elective Transmission Upgrade, TS = Transmission Service ISO-NE's request type: most rows are generation (G); elective-transmission-upgrade (ETU) and transmission-service (TS) requests are NOT generation and may carry blank fuel/MW. Filter by ISO-NE's EXACT code.
jurisdiction the distinct jurisdiction codes served from the ISO-NE snapshot 3 F = FERC-jurisdictional, N = Non-FERC, U = Unknown (documented by ISO-NE's dropdown; may be absent from a given snapshot) Whether the interconnection is under FERC jurisdiction. ISO-NE's dropdown documents three values (the third, U=Unknown, may not appear in every snapshot). Served verbatim; filter by ISO-NE's EXACT code.
project_status the distinct build-progress statuses served from the ISO-NE snapshot 5 Under Study = Under study, Under Construction = Under construction, Partially In Service = Partially in service, In Service = In service (energized), Suspended = Suspended The SEPARATE build-progress reading, never collapsed into application_status. Blank where ISO-NE shows no icon (most active/withdrawn rows). Filter via detail records; values are ISO-NE's exact legend labels.
study_phase_status the distinct study-phase statuses emitted across the five study columns in the served snapshot 7 Document Posted = Study document posted (a study-document link is served), Executed = Executed (the IA folder icon), IA Filed Unexecuted = Interconnection Agreement filed, unexecuted, ISA Not Executed = Interconnection Service Agreement not executed, In Progress = Study in progress Per-stage study status: FS=Feasibility Study, SIS=System Impact Study, OS=Optional Study, FAC=Facilities Study, IA=Interconnection Agreement. The values are the icon titles ISO-NE actually emits (these are the served codes — ISO-NE's printed legend lists a few labels that do not appear in the data, e.g. 'IA Executed', and omits 'IA Filed Unexecuted', so we key on the emitted titles). Blank where the stage has no icon.
fuel_type the distinct fuel-type tokens observed in the served ISO-NE snapshot 14 SUN = Solar, BAT = Battery / energy storage, WND = Wind, NG = Natural gas, DFO = Distillate fuel oil ISO-NE's fuel is a SPACE-DELIMITED list of EIA energy-source codes — e.g. SUN BAT (solar + battery, a co-located hybrid) or DFO NG (a single unit that burns distillate fuel oil OR natural gas, a dual-fuel unit). We serve the value VERBATIM and derive NO hybrid flag — distinguishing a co-located hybrid from a dual-fuel unit is the analyst's call from these codes. Filter by ISO-NE's EXACT value (the whole space-delimited string).
serv the distinct service codes observed in the served ISO-NE snapshot 8 CNR = Capacity Network Resource (deliverable capacity; Forward Capacity Auction eligible), NR = Network Resource (energy-injection capability), MIS = As-reported (ISO-NE publishes no public legend), CNI = As-reported (ISO-NE publishes no public legend), NI = As-reported (ISO-NE publishes no public legend) ISO-NE interconnection-service type. CNR (Capacity Network Resource — the higher Capacity Capability standard: deliverable capacity, needed to participate in the Forward Capacity Auction) and NR (Network Resource — the Network Capability standard: the ability to inject energy) are ISO-NE-defined. The remaining codes (MIS, CNI, NI, ES, NS) are ISO-NE's own service vocabulary served AS-REPORTED — ISO-NE publishes no consolidated legend for them. NOTE: both NA and N/A appear and are kept DISTINCT (served verbatim, never merged — whether ISO-NE intends them the same is the analyst's call). Filter by ISO-NE's EXACT value.
unit_type the distinct unit codes observed in the served ISO-NE snapshot 12 PV = as-reported (EIA-prime-mover hint: photovoltaic) — not ISO-NE-confirmed, WT = as-reported (EIA-prime-mover hint: wind turbine) — not ISO-NE-confirmed, CC = as-reported (EIA-prime-mover hint: combined cycle) — not ISO-NE-confirmed, GT = as-reported (EIA-prime-mover hint: combustion/gas turbine) — not ISO-NE-confirmed, ST = as-reported (EIA-prime-mover hint: steam turbine) — not ISO-NE-confirmed ISO-NE publishes no public legend for the Unit column, so these are served AS-REPORTED. The codes align with the standard EIA prime-mover set (PV photovoltaic, WT wind turbine, CC combined cycle, GT combustion/gas turbine, ST steam turbine, IC internal combustion, FC fuel cell, PS pumped storage, HD hydro, OT other) — offered as a HINT, not ISO-NE-confirmed; we do not assert a mapping ISO-NE has not published. Filter by ISO-NE's EXACT code.
dev the distinct Dev codes observed in the served ISO-NE snapshot 4 PD = as-reported (ISO-NE publishes no public legend), BL = as-reported (ISO-NE publishes no public legend), CD = as-reported (ISO-NE publishes no public legend), NA = as-reported (no Dev code) ISO-NE publishes no public legend for the Dev column; the codes (PD, BL, CD, NA) are served AS-REPORTED and we do not map them. Filter by ISO-NE's EXACT code.

Agent Workflow

  1. Call list_capabilities_v1 and select power.interconnection_queue_isone.
  2. Call describe_power_interconnection_queue_isone_v1 to inspect valid filters, groupings, metrics, and citation fields.
  3. Call query_power_interconnection_queue_isone_v1 with bounded JSON params.
  4. If the answer needs proof, pass a returned row-level citation object to get_source_evidence_v1.
  5. Answer with the resolved as_of and relevant citations. Present returned metrics as authoritative for their declared source, snapshot, grain, and aggregation.
