hl7-v2-fhir-mcp-server

MCP server for the HL7 v2.5.1 → FHIR R4 crossing — field, datatype and code-value mappings, plus whole-message conversion of ORM, ADT and ORU into a transaction Bundle, with a warning for every value it cannot map faithfully.

// tools this server exposes9 tools

These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

list_message_mappings

List the HL7 v2.5.1 message types this server converts and the FHIR R4 resources each one produces.

get_message_mapping

Get the full segment-to-resource plan for one HL7 v2.5.1 message type, including the known conversion pitfalls.

get_segment_mapping

Get the field-by-field FHIR mapping for one HL7 v2.5.1 segment.

get_field_mapping

Get the FHIR target for one HL7 v2.5.1 field, e.g. PID-5 or OBR-25, with the datatype mapping that applies to it.

get_datatype_mapping

Get the component-by-component FHIR datatype mapping for an HL7 v2.5.1 datatype.

lookup_concept_map

Translate an HL7 v2.5.1 table value into its FHIR code, or list a whole table's ConceptMap.

which_v2_fields_feed

Reverse lookup: given a FHIR resource type, list every HL7 v2.5.1 field this server maps into it.

convert_datetime

Convert an HL7 v2.5.1 TS/DTM value to a FHIR date or dateTime, preserving the source precision.

convert_message

Convert a full HL7 v2.5.1 ORM, ADT or ORU message into a FHIR R4 transaction Bundle, with warnings for everything that could not be mapped faithfully.

Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

9/9 tools missing one or more hints — list_message_mappings (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_message_mapping (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_segment_mapping (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +6 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Tests exist

No test files found

Add tests that exercise each declared tool.

Production dependencies are patched

0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.12.0 (high), @modelcontextprotocol/sdk@1.12.0 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 4 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
