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**: 23/100 - No malware scan is available for this kind of package: the supply-chain vendors we use do not cover it. This is a permanent gap in our coverage, not a finding about the package. - Known CVEs were checked across the 99 of 99 dependencies we could resolve, so this covers what we could see, not the whole tree. - No install/post-install scripts declared. - 32 of 99 dependencies flagged as unhealthy. - **Provenance & Transparency**: 48/100 - Source repository is publicly reachable at the declared URL. - Provenance check failed: no build-provenance attestation is published. - Clear OSI-approved license (MIT). - Actively maintained (last published 0 days ago). - Publishes a security disclosure policy (SECURITY.md). - **Schema Quality & AI Usability**: 67/100 - AI-judged instruction clarity (good). - Context-footprint check failed: tool/resource definitions use about 408 tokens (~204/item across 2 items; 2 tools + 0 resources), over budget; trim descriptions and params. - Usage-examples check failed: none of the tools include examples. - **Stability & Change Management**: 0/100 - Stability observed for 0 of 30 days with no destabilising changes; credit accrues until the full window elapses. - **Tool Coverage**: 100/100 - 100% of tools have a non-trivial description (not blank, and not just the tool's name). - 100% of tool parameters carry a description. - **Tool Safety**: 100/100 - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured. - We read all 2 captured tool definition(s), and no name or description among them implies an irreversible operation. - An AI judge read all 2 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. ## Install ### How do I install the io.github.Colchora/dmt-receipts MCP server? io.github.Colchora/dmt-receipts ships as an MCPB bundle, a single file you download and open in an MCP host that supports MCPB bundles, such as Claude Desktop. The host reads the launch command from the bundle's own manifest, so there is no command to copy. Before opening it, check the file's SHA-256 matches the one the MCP registry declares for it, 8cfc6588cbc726ea785214275dd1873aede64199c3b1ab24168eb81aac5abaaf; the commands to do that are on this page. If it does not match, do not open it. - Download bundle: `https://github.com/Colchora/dmt-receipts/releases/download/v0.2.0/dmt-receipts-0.2.0.mcpb` - SHA-256: `8cfc6588cbc726ea785214275dd1873aede64199c3b1ab24168eb81aac5abaaf` ### Verify on macOS / Linux ```bash echo "8cfc6588cbc726ea785214275dd1873aede64199c3b1ab24168eb81aac5abaaf dmt-receipts-0.2.0.mcpb" | shasum -a 256 -c ``` ### Verify on Windows (PowerShell) ```powershell (Get-FileHash -Algorithm SHA256 .\dmt-receipts-0.2.0.mcpb).Hash -eq "8cfc6588cbc726ea785214275dd1873aede64199c3b1ab24168eb81aac5abaaf" ``` ## Changelog Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims. ### 2026-11-05 (score 47) First indexed and scored. ## MCP tools (2) ### `prepare_memory` (~154 tokens) Canonicalize a dmt-memory/v1 JSON memory, SHA-256 it, and return an Ordinals/TAP inscription recipe (content UTF-8 + optional dta pointer). Does not broadcast a Bitcoin transaction or pay fees. Permanence requires inscribing the content on Bitcoin L1 via TAP Wallet or any Ordinals/TAP tool. Input parameters: - `agent_id` (string, required): Stable agent identifier - `content` (required): Memory payload (string, object, array, number, or boolean) - `created_at` (string): Optional ISO-8601 UTC timestamp ending in Z; defaults to now - `key` (string, required): Memory key / slug / path - `tags` (array): Optional string tags; defaults to [] ### `verify_inscription` (~254 tokens) Recompute the canonical SHA-256 of a dmt-memory/v1 object and, when inscription_id is provided, attempt to fetch Ordinals content and compare bytes. Optionally enrich with soft-fail Trac Network TAP/DMT index metadata (deployment, mint holder, transfer amount, accumulator). Returns explorer links plus a trac object. Does not use calendar digest proofs. Input parameters: - `fetch_content` (boolean): Fetch inscription content from ordinals.com when inscription_id is set (default true) - `include_trac` (boolean): When inscription_id is set, query Trac TAP/DMT index metadata (default true). Soft-fails if Trac is down. - `inscription_id` (string): Bitcoin Ordinals inscription id (txid + 'i' + index) - `memory` (object, required): Full dmt-memory/v1 object (agent_id, key, content, tags, created_at) - `sha256` (string): Optional expected hex digest to cross-check - `trac_rest_base` (string): Optional self-hosted tap-reader REST origin. Falls back to env DMT_TRAC_REST, then public Socket.IO at tap.trac.network. - `txid` (string): Optional Bitcoin transaction id ## Diagnostics Captured diagnostic sections: Provenance, Dependencies.

Prepare and verify TAP/Ordinals payloads for AI agent memories on Bitcoin. This page covers its MCPB bundle (https://github.com/Colchora/dmt-receipts/releases/download/v0.2.0/dmt-receipts-0.2.0.mcpb). ### Is the io.github.Colchora/dmt-receipts MCP server safe to use? io.github.Colchora/dmt-receipts scores 47 out of 100 on VerifyMCP. It declares no install or post-install scripts. 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 io.github.Colchora/dmt-receipts MCP server expose? io.github.Colchora/dmt-receipts exposes 2 tools: prepare_memory, verify_inscription. Their descriptions and schemas cost roughly 408 tokens of context every time the server is loaded. ### What licence is the io.github.Colchora/dmt-receipts MCP server under? io.github.Colchora/dmt-receipts declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls. ### What did VerifyMCP test on the io.github.Colchora/dmt-receipts MCP server? VerifyMCP ran 14 checks on io.github.Colchora/dmt-receipts, covering Known CVEs, Install scripts, Dependency health, Source repository and 10 more. 2 items could not be completed, a gap on our side rather than a finding about io.github.Colchora/dmt-receipts: Malware scan and Stability. One category scores 0 for that reason, because we only credit what we can confirm. Endpoint Security and Transport & Reachability do not apply to an MCPB bundle, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out. ## Links - Repository: https://github.com/Colchora/dmt-receipts - Changelog RSS feed: https://verifymcp.io/servers/colchora-dmt-receipts/dmt-receipts.xml - Changelog JSON feed: https://verifymcp.io/servers/colchora-dmt-receipts/dmt-receipts/changelog.json - Trust report (JSON): https://verifymcp.io/servers/colchora-dmt-receipts/dmt-receipts.json - HTML version of this page: https://verifymcp.io/servers/colchora-dmt-receipts/dmt-receipts
