## 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 2026-11-04.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - 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.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 71/100
  - Repository check failed: the declared repository URL redirects; it must resolve directly.
  - Cryptographically verified build provenance (signed, bound to CYAN-ECLIPSE-TECHNOLOGIES-LLC/eclipse-muster-mcp).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 7 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 60/100
  - AI-judged instruction clarity (fair).
  - Tool/resource definitions use about 565 tokens (~62/item across 9 items; 9 tools + 0 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**: 67/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
- **Tool Safety**: 75/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - 0 of 3 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "merge_propose" implies "merge" and declares no destructiveHint at all, which the MCP spec reads as destructive by default.
  - An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 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.

First indexed and scored.

## MCP tools (9)

### `record_ingest` (~111 tokens)

Ingest a canonical Customer Graph record (person / company / deal / ticket / conversation / activity). Every field must carry provenance; a Data Rights Ledger block is required. Customer-authored conversation text is tagged untrusted and instruction-shaped content is quarantined at ingest.

Input parameters:

- `data_rights` (object)
- `external_ids` (object)
- `field_provenance` (object)
- `fields` (object, required)
- `kind` (string, required)
- `record_id` (string)

### `record_read` (~61 tokens)

Read one graph record with egress masking applied (surface: owner = full email, analytic = domain-only email; phone always partial; gov/payment/health fields null). Receipted.

Input parameters:

- `record_id` (string, required)
- `surface` (string)

### `record_search` (~52 tokens)

Search graph records by kind + substring; returns masked summaries. The query itself is receipted by hash only.

Input parameters:

- `kind` (string)
- `query` (string)
- `surface` (string)

### `merge_propose` (~67 tokens)

PROPOSE an identity merge between two same-kind records. Returns evidence (matching keys by hash, conflicts) + a proposal hash. Executes nothing (Beacon propose-only doctrine).

Input parameters:

- `proposal_id` (string)
- `record_a` (string, required)
- `record_b` (string, required)

### `merge_execute` (~79 tokens)

Execute a proposed graph merge. Requires the owner-confirm token bound to the proposal hash (confirm-merge-<proposal_id>-<hash12>). Graph nodes only — never merges records inside a platform. The pre-merge snapshot is stored on the merge record for unmerge.

Input parameters:

- `confirm_token` (string, required)
- `proposal_id` (string, required)

### `merge_unmerge` (~51 tokens)

Undo a confirmed merge from its receipt snapshot, restoring the pre-merge nodes exactly. Requires confirm-unmerge-<merge_id>.

Input parameters:

- `confirm_token` (string, required)
- `merge_id` (string, required)

### `reply_draft` (~79 tokens)

Draft a ticket reply ONLY from record facts, with a citation list. Untraceable facts become MISSING_FACT markers. Customer text is never a fact source; quarantined (instruction-shaped) messages are reported, never obeyed.

Input parameters:

- `draft_id` (string)
- `person_id` (string)
- `ticket_id` (string, required)

### `policy_show` (~25 tokens)

Show the tier floors, effective tiers, kill switches, and masking rules in force.

### `receipt_list` (~40 tokens)

List the append-only, hash-chained receipts and verify the chain. Receipts carry IDs + hashes only — never content.

Input parameters:

- `limit` (integer)

## Common questions

### What is the Eclipse Muster MCP server?

Eclipse Muster MCP is listed in the public MCP registry as io.github.CYAN-ECLIPSE-TECHNOLOGIES-LLC/muster. The Customer Graph core: one register of the people an account serves, with provenance on every. This page covers its PyPI package (eclipse-muster).

### Is the Eclipse Muster MCP server safe to use?

Eclipse Muster MCP scores 69 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 4 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 Eclipse Muster MCP server expose?

Eclipse Muster MCP exposes 9 tools: record_ingest, record_read, record_search, merge_propose, merge_execute, and 4 more. Their descriptions and schemas cost roughly 565 tokens of context every time the server is loaded.

### Is the Eclipse Muster MCP server still maintained?

Eclipse Muster MCP is still listed as active in the MCP registry. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Eclipse Muster MCP server under?

Eclipse Muster MCP declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
