Version: 1.0.0

Capabilities

tools

Server instructions

Read-only access to the OpenTelemetry semantic conventions, specification and OTLP definitions, with their release histories. Reach for check_attribute_names before asserting that an attribute key is current, and search_requirements before asserting what the spec requires - the conventions rename keys every month and a model's training data is usually behind them. Note that the OTLP protocol specification lives in the opentelemetry-proto repository, not the specification one; both are covered.

Known tools 8

search

Search everything semconv.com knows in one call: both attribute registries, metrics, spans, events, entities, every MUST/SHOULD/MAY in the specification and in OTLP, the OTLP wire messages and the domain pages.

Inferred read-only

list_versions

List every tracked release of all three OpenTelemetry sources - semantic conventions, the specification, and OTLP - newest first, with publication dates and how many breaking, notable and editorial changes each one introduced.

Inferred read-only

check_attribute_names

Given attribute keys a codebase emits or queries, report which are deprecated, renamed, moved to another registry, or absent.

Inferred read-only

get_attribute

Full definition of one semantic-conventions attribute: type, stability, guidance note, examples, which signals carry it, and its release-by-release history.

Inferred read-only

search_attributes

Search the semantic-conventions attribute registry by substring against ids and descriptions, optionally narrowed to a namespace or to deprecated entries only.

Inferred read-only

diff_versions

What changed between two tracked versions of one source.

Inferred read-only

search_requirements

Search the RFC 2119 requirements of the OpenTelemetry specification and the OTLP protocol document - the sentences that actually bind an implementation.

Inferred read-only

get_otlp_message

One OTLP wire definition in full: every field with its number, type and cardinality, or every value of an enum.

Inferred read-only
