H/M Content Credentials Evidence Verifier
net.hogarmas/content-credentials · 1.2.0
Free C2PA 2.4 triage and reproducible official trust snapshot. No media, keys, or payment.
Nobody here has read this server's code, because it publishes none. The description above is the maker's own, from the registry. A connection test shows whether it answers and what tools it says it has; it never calls a tool, so it cannot show what one does with your data.
Where it sits in the directory's order
What can be seen from outside, weighed as the directory publishes.
Observable signals: 35 of 100 points (at most 60 here)
| Input | Points | What was seen |
|---|---|---|
| Source published | held at 0 | No entry here publishes source: that is what puts it in this directory. |
| Licence stated | held at 0 | With no files, there is nothing for a licence to be stated in or held against. |
| Advisory state | held at 0 | Advisory databases index packages, and these entries publish none, so there is nothing to look up. |
| Auth declared | 0 of 15 | The registry entry declares no key. That is what it declares, not a finding that it has no protection. |

Connection test
The MCP handshake, then a request for the tool list, with no key and no data of yours. Run nightly, and by anyone, at most once every ten minutes per server.
It completed the handshake and listed 7 tools.

The tools it lists (7, as of 10 hours ago)
The tool-description rules found nothing in these descriptions. They look for instructions aimed at a model and for hidden characters; they cannot see what a tool does when it runs.
get_content_credentials_capabilitiesReturns the free tools, byte limits, privacy behavior and interpretation boundaries before any evidence JSON is submitted.
triage_c2pa_validation_statusesClassifies up to 200 C2PA validation status observations against the complete 2.4 standard catalog, flags class mismatches, separates custom codes and returns bounded remediation. Accepts codes or crJSON-style status groups; no media, URL fetching, authentication or payment.
run_content_credentials_self_checkRuns a deterministic, zero-input check of valid evidence, tamper detection and audit-chain verification using a synthetic fixture. No source media or caller data is used.
verify_content_credentials_envelopeChecks the schema, privacy boundaries and canonical SHA-256 digest of an H/M evidence envelope. It does not inspect source media or authenticate an issuer.
verify_content_credentials_auditChecks report identity, source-report digest and the local custody hash chain. It does not prove operator identity, authorship or factual truth.
create_content_credentials_policy_profileCreates one versioned policy profile from a fixed preset and optional rule overrides. It accepts no source media or evidence and does not authenticate the policy author.
verify_content_credentials_policy_decisionChecks the policy checksum, decision checksum, every per-item rule outcome and aggregate counts. It does not inspect source media, authenticate the sender or certify compliance.
How this entry becomes a listing
For the maker. The catalogue lists what it can read, and this server publishes nothing to read yet. There are two routes, and only the first is open today.
Publish the source Open today
- Put the server's source in a public repository on github.com, with a licence.
- Keep a server.json in that repository naming this server,
net.hogarmas/content-credentials, and declare the repository in it:"repository": { "url": "https://github.com/owner/repo", "source": "github" }, adding"subfolder"when the server lives in a folder. - Publish that version to the official MCP registry.
- The nightly registry sweep records the declaration. This page stays, dated, and says the source is declared but not yet read.
- The catalogue reads declared repositories at a pinned commit, in batches run by hand, and lists the servers that meet the batch's rules (among them a server.json at that commit naming the server, an https endpoint and a licence). When it lists this server, this page links to the listing. There is no schedule, so no date can be promised.
