- Get my KOTC study snapshotget · Read a minimized, current coaching snapshot for the exact OAuth-connected KOTC MCAT learner. It includes safe goal, momentum, aggregate subject-performance, bookmark, and exam-summary fields. It never accepts a user ID and never returns email, demographics, payments, raw answers, raw chat, or another learner's data.RexaKing of the CurvePluginoptionalEducation
- Get my KOTC subject performanceget · Read coherent aggregate MCAT question performance by category and subcategory for the exact connected learner. Rejects inconsistent totals instead of reporting impossible accuracy. No raw questions, answers, IDs, or peer data are returned.RexaKing of the CurvePluginoptionalEducation

Use this to find public KOTC resources; use fetch with a returned exact ID for full citable content. Do not use it to search the open web or learner data.RexaKing of the CurvePluginoptionalEducation
- get_factoryget · Load one factory public profile by slug or name. Examples: slug 'smsenra', name 'SMSenra'. Use after the user picks a factory. Prefer slug from match/search results (factory_id equals slug).NovaSupplierNovaSupplierPluginnoneCommerce
- match_factoriesmatch · Match factories to a free-text apparel sourcing brief with grounded explanations. Examples: 'merino baselayers Denmark low MOQ GOTS flatlock', 'padel tops bonded seams Portugal', 'budget streetwear hoodies under 300 units'. Use for descriptive product stories.NovaSupplierNovaSupplierPluginnoneCommerce
- search_factoriessearch · Filter Portuguese apparel manufacturers by category, certification, MOQ, or keywords. Examples: 'Portuguese knitwear with GOTS', 'denim factories low MOQ', 'activewear Portugal'. Use when the user already knows filter terms, not a free-text product story.NovaSupplierNovaSupplierPluginnoneCommerce
- Autocomplete Awarding Agencyautocomplete · Find awarding agency names by partial match.
USASpending search filters require the EXACT awarding agency name
(slugs return zero). Use this to resolve a partial name to the canonical
one before passing to search_awards() awarding_agency parameter.USAspending MCP1102toolsPluginnoneOperations
- Autocomplete CFDAautocomplete · Find CFDA (Catalog of Federal Domestic Assistance) program numbers
by partial title or program number. CFDA codes are used in grants.USAspending MCP1102toolsPluginnoneOperations
- Autocomplete Funding Agencyautocomplete · Find funding agency names by partial match (companion to awarding agency).USAspending MCP1102toolsPluginnoneOperations
- Autocomplete Glossaryautocomplete · Find glossary terms (acquisition + spending vocabulary) by partial match.USAspending MCP1102toolsPluginnoneOperations
- Autocomplete NAICSautocomplete · Autocomplete lookup for NAICS codes.
Accepts partial codes ('541') or keywords ('software'). Returns matching
NAICS entries with code and description.
Minimum 2 characters required. Short queries silently match substrings
inside parenthetical notes (e.g. 'x' matches 'except') and produce
nonsense results, so we require 2+ chars.
exclude_retired defaults to True. The upstream NAICS taxonomy still
returns codes retired in 2012/2017/2022; these are almost never what
callers want. Set exclude_retired=False to include them.USAspending MCP1102toolsPluginnoneOperations
- Autocomplete PSCautocomplete · Autocomplete lookup for Product/Service Codes (PSC).
Works best with code prefixes ('R499', 'D3', 'AJ') or keywords
('professional', 'application'). Returns matching PSC entries with
code and description.
Minimum 2 characters required. Single-character queries return first-N
alphabetical results from the upstream API (useless for matching) and
empty strings return HTTP 400.USAspending MCP1102toolsPluginnoneOperations
- Autocomplete Recipientautocomplete · Find recipient names by partial name or UEI/DUNS.
NOTE: this endpoint returns recipient NAMES only. It does NOT return the
recipient hash needed by get_recipient_profile() and
get_recipient_children() (and its uei/duns fields come back null).
To get a hash, take a name from here and pass it to search_recipients(),
whose results carry the hash in their 'id' field.USAspending MCP1102toolsPluginnoneOperations
- Awards Last Updatedawards · Get the timestamp of the last USASpending award data refresh.
Use this to determine data freshness when comparing to other sources
(SAM.gov Contract Awards API for example).USAspending MCP1102toolsPluginnoneOperations
- Get Agency Awardsget · Get award summary totals for an agency in a given fiscal year.
Returns obligation totals by award category. toptier_code is auto-padded
to 3 digits if a shorter numeric value is supplied.USAspending MCP1102toolsPluginnoneOperations
- Get Agency Budgetary Resourcesget · Get an agency's budgetary resources by fiscal year.
Returns total budgetary resources, obligations, outlays, and discretionary
vs mandatory breakdown for each fiscal year on file.USAspending MCP1102toolsPluginnoneOperations
- Get Agency Federal Accountsget · List the Treasury Account Symbols (federal accounts) used by an agency.
Returns each federal account with its obligated amount and gross outlay
for the given fiscal year. Useful for understanding how an agency's
money flows through Treasury.USAspending MCP1102toolsPluginnoneOperations
- Get Agency Object Classesget · List the object class breakdown (what an agency spends money on).
Object classes are OMB categories: Personnel Compensation, Travel,
Contractual Services, Equipment, Grants, etc. Useful for understanding
what types of expenditures an agency makes.USAspending MCP1102toolsPluginnoneOperations
- Get Agency Obligations by Award Categoryget · Get an agency's obligation breakdown by award category.
Returns total obligated dollars split by category: contracts, IDVs, grants,
loans, direct payments, other. Quick way to see what mix of award types
an agency uses (heavy contractor agency vs grant-issuing agency vs mixed).USAspending MCP1102toolsPluginnoneOperations
- Get Agency Overviewget · Get summary information for a specific agency in a given fiscal year.
toptier_code is the 3- or 4-digit agency code (e.g. '097' for DoD,
'075' for HHS, '080' for NASA). Shorter inputs like '97' are left-padded
to '097' automatically. Get valid codes via list_toptier_agencies().USAspending MCP1102toolsPluginnoneOperations
- Get Agency Program Activitiesget · List the program activities (specific programs) within an agency.
Program activities are the specific named programs that obligate funds
(e.g., 'Cybersecurity and Infrastructure Security Agency'). Useful for
pinpointing which program funds a specific activity.USAspending MCP1102toolsPluginnoneOperations
- Get Agency Sub-Agenciesget · List the subordinate (subtier) organizations of a toptier agency.
Returns each sub-agency with its obligations, transaction count, and
new-award count for the given fiscal year. Useful for finding the
canonical subtier name to pass into search_awards() awarding_subagency.
sort accepts name, total_obligations, transaction_count, or
new_award_count (this endpoint has no outlay column; a former
'total_outlays' option was rejected by the API with HTTP 400).USAspending MCP1102toolsPluginnoneOperations
- Get Award Countget · Count awards matching filters, broken down by award category.
Returns counts grouped by: contracts, idvs, grants, loans, direct_payments, other.
Use this for dimensional analysis: how many FFP vs T&M awards, how many
competed vs sole-source, how many small business set-asides, etc.
Unlike search_awards, this returns total counts across ALL award categories
in a single call (not just the one specified in award_type). The award_type
parameter is ignored here; filters apply to the count query directly.
def_codes filters to Disaster Emergency Fund codes; see
get_def_codes_reference().
At least one filter is required (the API rejects empty filter sets with HTTP 400).
Typical usage: pass time_period_start + time_period_end, or a keywords/agency filter.USAspending MCP1102toolsPluginnoneOperations
- Get Award Detailget · Fetch full details for a single award by its generated_internal_id.
Use the generated_internal_id value returned by search_awards to fetch
the complete award record. Returns: PIID, full description, total
obligation, recipient details, parent award info, latest transaction
contract data (competition, set-aside, pricing type), period of
performance, place of performance, NAICS hierarchy, PSC hierarchy,
base and all options value, and sub-award totals.
Accepts either a generated award id (CONT_AWD_*, CONT_IDV_*, ASST_NON_*,
ASST_AGG_*) or the numeric internal database id from a prior response.
Example generated_award_id format: CONT_AWD_N0002424C0085_9700_N0002421D0001_9700USAspending MCP1102toolsPluginnoneOperations
- Get Award Federal Account Countget · Count of distinct federal accounts (TAS) funding an award.USAspending MCP1102toolsPluginnoneOperations
- Get Award Fundingget · Fetch File C funding data for an award: federal account, object class, program activity.
Shows which Treasury accounts, object classes, and program activities
funded an award. Useful for appropriations analysis and understanding
what colors of money paid for what.
Sort fields: reporting_fiscal_date, account_title,
transaction_obligated_amount, object_class.USAspending MCP1102toolsPluginnoneOperations
- Get Award Funding Rollupget · Get a rollup of an award's funding totals.
Returns total transaction obligated amount, awarding agency count,
funding agency count, and federal account count for a single award.
Useful for a one-line summary of an award's funding picture.USAspending MCP1102toolsPluginnoneOperations
- Get Award Subaward Countget · Count of subawards (FFATA subcontracts/subawards) reported on an award.USAspending MCP1102toolsPluginnoneOperations
- Get Award Transaction Countget · Count of transactions (modifications) on an award.USAspending MCP1102toolsPluginnoneOperations
- Get Award Types Referenceget · Return the full mapping of award type codes to descriptions.
Returns the canonical reference: contracts (A=BPA Call, B=Purchase Order,
C=Delivery Order, D=Definitive Contract), IDVs, grants, loans, etc.
Authoritative source if you're unsure what a code letter means.USAspending MCP1102toolsPluginnoneOperations
- Get DEF Codes Referenceget · Return all Disaster Emergency Fund (DEFC) codes with public laws.
DEFCs are used to filter awards funded by specific supplemental
appropriations (COVID-19, IIJA, IRA, etc.).USAspending MCP1102toolsPluginnoneOperations
- Get Federal Account Detailget · Get an individual federal account's metadata + budgetary resources.USAspending MCP1102toolsPluginnoneOperations
- Get Federal Account Fiscal Year Snapshotget · Get a single-fiscal-year snapshot of a federal account's resources.
Important: this endpoint takes the numeric `account_id` (e.g. 4595), NOT
the alphanumeric `account_number` (e.g. "027-5183") used by the other
federal-account endpoints. The list_federal_accounts response includes
both fields per record. Pass the integer account_id here.USAspending MCP1102toolsPluginnoneOperations
- Get Federal Account Object Classesget · Get the object class breakdown of obligations for a federal account.
IMPORTANT: the returned obligations are CUMULATIVE across all reported
fiscal years (FY2017 onward, the DATA Act window), not a single year.
They are NOT comparable to get_federal_account_fy_snapshot(), which is
single-year (verified live: account 021-0725 summed to $3.38B here vs
$0.42B obligated in its FY2024 snapshot). The upstream endpoint has no
year control: a fiscal_year body parameter is accepted but ignored, so
none is exposed here.
Note: this endpoint requires POST (not GET like the other federal account
sub-endpoints). Live audit caught this; the body is empty.USAspending MCP1102toolsPluginnoneOperations
- Get Federal Account Program Activitiesget · Get the program activities funded under a federal account.USAspending MCP1102toolsPluginnoneOperations
- Get Glossaryget · Get the full USASpending glossary of acquisition + spending terms.USAspending MCP1102toolsPluginnoneOperations
- Get IDV Activityget · List child task/delivery orders awarded under an IDV.
Results are ALWAYS sorted by obligated amount, descending; the endpoint
accepts no sort or order parameters. (Earlier releases exposed sort/order
here, but the API silently ignored them: the advertised default of
period_of_performance_start_date was never the actual ordering. Round 10
audit finding.) For date-ordered children use get_idv_children(), whose
endpoint does honor sort/order.
hide_edge_cases=True filters out child awards missing obligated/awarded
amounts or end dates.USAspending MCP1102toolsPluginnoneOperations
- Get IDV Amountsget · Top-line amounts for an Indefinite Delivery Vehicle (IDV).
Returns child IDV count, child award count, child award total obligation,
and base/option values rolled up across all task/delivery orders under
the IDV. Pass a CONT_IDV_* generated_internal_id.USAspending MCP1102toolsPluginnoneOperations
- Get IDV Childrenget · Fetch child awards (task/delivery orders) under an IDV.
For a Multiple Award IDV, child_awards returns the task orders or delivery
orders placed against it. For a parent IDV, child_idvs returns the
downstream IDV structure. grandchild_awards walks the hierarchy.
Field name differences from search_awards: children use 'piid' (not
'Award ID'), 'obligated_amount' (not 'Award Amount'), and
'generated_unique_award_id' (not 'generated_internal_id').
An active vehicle can legitimately return zero children here:
USASpending's award cross-linking has gaps. Treat an empty result as a
reporting gap, not proof that no orders exist. A search_awards call
with keywords=['<IDV PIID>'] sometimes recovers the orders, but it can
also be empty on the same vehicle.USAspending MCP1102toolsPluginnoneOperations
- Get IDV Fundingget · List the funding records (File C) for an IDV's child orders.USAspending MCP1102toolsPluginnoneOperations
- Get IDV Funding Rollupget · Funding rollup totals for an IDV (single dict, not paginated).USAspending MCP1102toolsPluginnoneOperations
- Get NAICS Detailsget · Get details for a NAICS code (2-6 digits).
Returns the NAICS description, parent categories, and child subcategories
if applicable.USAspending MCP1102toolsPluginnoneOperations
- Get PSC Filter Treeget · Get the PSC hierarchy tree.
Pass an empty path for the top-level. Drill down with paths like
'Service/R/' to get the service professional services tree, or
'Product/5' for product codes starting with 5.USAspending MCP1102toolsPluginnoneOperations
- Get Recipient Childrenget · Get the child recipients (subsidiaries) of a parent recipient.
Pass the parent recipient's 12-character UEI (or legacy 9-digit DUNS).
Do NOT pass a recipient hash: the /recipient/children/ endpoint is the
one recipient endpoint keyed by UEI/DUNS, and it rejects hashes with
HTTP 400. Get the UEI from search_recipients() results (the 'uei' field
of the -P row) or from get_recipient_profile().
Returns the child recipients, each with its own -C suffixed recipient_id
hash usable with get_recipient_profile(). Useful for mapping corporate
structures (e.g. Lockheed Martin parent -> all its subsidiaries).
year: optional 'all', 'latest', or a fiscal year like 2026.
The upstream endpoint returns a JSON array; it is wrapped here as
{"results": [...], "total": N} to keep the dict-only response invariant.USAspending MCP1102toolsPluginnoneOperations
- Get Recipient Profileget · Get full profile for a recipient by their USASpending hash.
Returns recipient details: name, UEI, DUNS, business categories, location,
parent (if any), and lifetime award totals. The hash is the 'id' field
returned by search_recipients(). (autocomplete_recipient does NOT return
hashes; it is a name lookup only.)
year: optional 'all' or a fiscal year like 2026 (int or str both
accepted). Default is 'latest' (trailing 12 months).USAspending MCP1102toolsPluginnoneOperations
- Get State Profileget · Get spending profile for a US state by its 2-digit FIPS code.
Examples: '06' = California, '48' = Texas, '24' = Maryland, '51' = Virginia.
Returns award totals, top agencies, top recipients, and district data.USAspending MCP1102toolsPluginnoneOperations
- Get Submission Periodsget · Return the list of agency submission periods (when each agency last
submitted data for each fiscal period). Useful for understanding which
quarters of which fiscal years have full data coverage.USAspending MCP1102toolsPluginnoneOperations
What is Tool Explorer?
Tool Explorer indexes the callable tool names and descriptions attached to public registry profiles. It is useful for seeing what agents can actually invoke, not just which profile exists.
How do category and verb filters work?
Category filters use the live registry category rollup. Verb filters use the public tool insights rollup, so the page stays backed by the same read models as the tracker charts.
Why do auth requirements matter?
Auth requirements show whether a tool is likely usable without account connection, requires authentication, is private, or is unknown in the current snapshot.
