## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Supply Chain Security**: 50/100
  - Malware scan not yet available for this package.
  - No known CVEs affecting this package version or its production dependencies.
  - Runs hatchling.build at install time, a recognised build step with no custom scripting around it.
  - 1 of 35 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 100/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to vardhjain/finos-mcp).
  - Clear OSI-approved license (Apache-2.0).
  - Actively maintained (last published 10 days ago).
  - Publishes a security disclosure policy (SECURITY.md).
- **Schema Quality & AI Usability**: 39/100
  - 0% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 712 tokens (~71/item across 10 items; 9 tools + 1 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 9 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 11 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## MCP tools (9)

### `describe_type` (~65 tokens)

Describe one CDM type by name (TradeState) or fully qualified name
(cdm.event.common.TradeState): every field with its type and cardinality, choice
alternatives, which types reference it, and the schema resource to cite.

Input parameters:

- `name` (string, required)

Output parameters:

- `alternatives` (array): For choice types: the alternative type names.
- `description`
- `extends`
- `fields` (array)
- `kind` (string)
- `name` (string)
- `namespace` (string)
- `root_type` (boolean)
- `schema_filename` (string)
- `schema_uri` (string)
- `used_by` (array)

### `list_types` (~82 tokens)

List CDM types. Filter by namespace prefix (cdm.product), kind (type, enum, choice,
meta) or root types only (the 16 top-level document types such as TradeState).

Input parameters:

- `kind`
- `namespace`
- `page` (integer)
- `page_size` (integer)
- `root_only` (boolean)

Output parameters:

- `items` (array)
- `page` (integer)
- `page_size` (integer)
- `total` (integer)

### `list_products` (~70 tokens)

Catalogue of product types: the product template types (NonTransferableProduct,
TransferableProduct, TradableProduct, EconomicTerms, Payout) and every Payout
alternative (InterestRatePayout, CreditDefaultPayout, OptionPayout, ...), with the
vendored samples that use each.

Output parameters:

- `cdm_version` (string)
- `entries` (array)

### `validate_object` (~144 tokens)

Validate a CDM JSON object against the published schema. The format (Rune with
'@type'/'@key'/'@ref' keys, or legacy 'value'/'meta' wrappers) is detected unless
given. The type comes from '@type' or the type argument (e.g. TradeState). Use
schema_version='6.30.0' for legacy documents produced by CDM 6. Every issue carries
the JSON path in your document and a kind (required, cardinality, type, enum, ...).

Input parameters:

- `format` (string)
- `object` (object, required)
- `schema_version`
- `type`

Output parameters:

- `format_detected`
- `issues` (array)
- `stats` (object)
- `type`
- `valid` (boolean)
- `validator` (string)
- `warnings` (array)

### `explain_event` (~82 tokens)

Explain a CDM BusinessEvent. Pass the event JSON to read its qualifier, instruction
kinds, before/after trade states and the products involved; or pass a qualifier name
(Execution, Termination, ...) to get the Qualify_* rule from the CDM sources and a
sample that exercises it.

Input parameters:

- `event`
- `qualifier`

Output parameters:

- `after_products` (array)
- `after_trade_count` (integer)
- `before_trade_count` (integer)
- `format_detected`
- `instruction_types` (array)
- `notes` (array)
- `qualifier`
- `qualify_function`
- `sample_uris` (array)

### `search_types` (~40 tokens)

Keyword search over CDM type names and descriptions (e.g. 'floating rate payout').

Input parameters:

- `k` (integer)
- `query` (string, required)

Output parameters:

- `result` (array)

### `get_sample` (~50 tokens)

Fetch one vendored sample document by name (see list_samples), e.g. a Rune-format
Execution BusinessEvent for an interest-rate swap, to use as a template.

Input parameters:

- `name` (string, required)

Output parameters:

- `citation_uri` (string)
- `format` (string)
- `json_document` (object)
- `name` (string)
- `root_type`

### `list_samples` (~41 tokens)

List the vendored sample documents (Rune-format from CDM 7.8.0, legacy from 6.30.0).

Input parameters:

- `format`

Output parameters:

- `samples` (array)

### `server_info` (~25 tokens)

Describe this server: standard version, upstream provenance, exposed counts, latency, policy.

Output parameters:

- `counts` (object)
- `latency` (object)
- `name` (string)
- `policy` (object)
- `read_only` (boolean)
- `resources` (array)
- `standard` (string)
- `standard_version`

FINOS MCP - Common Domain Model (community) is listed in the public MCP registry as io.github.vardhjain/finos-mcp-cdm. Read-only MCP for FINOS CDM 7.8.0 types and trade JSON validation. Independent project. This page covers its PyPI package (finos-mcp-cdm).

### Is the FINOS MCP - Common Domain Model (community) server safe to use?

FINOS MCP - Common Domain Model (community) scores 58 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the FINOS MCP - Common Domain Model (community) server expose?

FINOS MCP - Common Domain Model (community) exposes 9 tools: describe_type, list_types, list_products, validate_object, explain_event, and 4 more. Their descriptions and schemas cost roughly 599 tokens of context every time the server is loaded.

### Is the FINOS MCP - Common Domain Model (community) server still maintained?

FINOS MCP - Common Domain Model (community) is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
