UNESCO Institute for Statistics (UIS) MCP Server

Search UNESCO UIS indicators

uis_search_indicators
Read-onlyIdempotent

Search ~5,000 UNESCO UIS education, science, culture and communication indicators by keyword or code, with theme filters, to get indicator codes and data availability for uis_get_data.

Instructions

Search the UNESCO Institute for Statistics catalogue of ~5,000 indicators — education, science/R&D, culture and communication — by keywords in the name or code, optionally filtered by theme. All terms must match (AND, case-insensitive), so start with 2–3 words and drop terms if you get 0 results. Everyday and US wording is resolved to the UIS's own (enrollment→enrolment, spending→expenditure, preschool→pre-primary, university→tertiary, graduation→completion, girls/boys→female/male); when that happens the response says so in vocabulary_notes. Returns indicator codes to use with uis_get_data, plus each indicator's data availability (years, record count). Searches the catalogue only — it does not return statistical values (use uis_get_data); ILO labour statistics live in the sibling ILOSTAT MCP server.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
limitNoMaximum results (default 20)
queryYesKeywords, matched against indicator name and code, AND between terms (e.g. "literacy rate youth")
themeNoRestrict to one UIS theme
offsetNoResults to skip, for pagination (default 0)
provenance_modeNoProvenance verbosity: 'concise' (default — source, url, vintage, retrieval date, citation, license) or 'detailed' (full canonical block with dataset, dimension key and notices)

Output Schema

TableJSON Schema
NameRequiredDescriptionDefault
hintNo
offsetYes
showingYes
has_moreYes
indicatorsYes
provenanceYesProvenance block (contract v1.1). concise (default): source, source_url, data_vintage, retrieved_at, retrieval, citation, license; detailed: the full canonical block (dataset, dimension_key, notices, served_from_cache, ...). retrieval is the origin diagnostic of this call — requests made to the UIS Data API, attempts including retries, anomalies overcome (timeout, network, rate_limited, http_5xx, http_4xx, malformed_body) and unstable (true when anything had to be retried: treat the figures as obtained with difficulty); null when nothing was fetched from the UIS (catalogue or cached answer)

    • addedOutput schema / properties / provenance / description
      Added value: +"Provenance block (contract v1.1). concise (default): source, source_url, data_vintage, retrieved_at, retrieval, citation, license; detailed: the full canonical block (dataset, dimension_key, notices, served_from_cache, ...). retrieval is the origin diagnostic of this call — requests made to the UIS Data API, attempts including retries, anomalies overcome (timeout, network, rate_limited, http_5xx, http_4xx, malformed_body) and unstable (true when anything had to be retried: treat the figures as obtained with difficulty); null when nothing was fetched from the UIS (catalogue or cached answer)"

TDQS

A4.6/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnly/idempotent/non-destructive, so the safety profile is covered. The description goes further by disclosing matching semantics (AND, case-insensitive), automatic vocabulary normalization (enrollment→enrolment etc.) surfaced via vocabulary_notes, and the response payload (indicator codes plus data availability years/record count). Rate limits and result-ordering are the only notable omissions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with purpose then scope, exclusions, and search tips; every sentence carries information. It is dense as a single block—splitting the search-strategy and synonym notes into list form would improve scannability—but nothing is filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Complete for a search tool: purpose, scoping, alternatives, query strategy, synonym behavior, and return contents are all covered. An output schema exists so return values need not be detailed, yet the description still orients the agent on what the results enable.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3, but the description meaningfully enriches the query parameter by explaining AND semantics and the synonym resolution that shapes results, and clarifies that theme is an optional restriction. It adds interpretive value beyond the field-level schema text without duplicating it.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb (search) and resource (UIS indicator catalogue, ~5,000 indicators across education, science/R&D, culture, communication) and the matching fields (name or code). It explicitly distinguishes itself from uis_get_data (values) and the ILOSTAT sibling, so an agent can route correctly without opening a schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives explicit when-to-use, when-not-to-use, and alternatives: 'use uis_get_data' for statistical values and 'ILO labour statistics live in the sibling ILOSTAT MCP server'. It also adds actionable query strategy ('start with 2–3 words and drop terms if you get 0 results') and describes the synonym-resolution fallback.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
