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. How we score → Why this is hard to score →
Supply Chain Security0
- 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.Unverified
- Known CVEs could not be checked: we found no dependency list to check in this bundle: either it runs a compiled binary, whose bundled manifests we do not read, or none of the package.json, requirements.txt, pyproject.toml or uv.lock files it ships for its runtime declares a dependency we can read (a requirements.txt that only points at a setup.py project, a local path, or a nested requirements file we cannot follow counts as none).Unverified
- Install-script risk not yet assessed.Unverified
- Dependency health could not be checked: we found no dependency list to check in this bundle: either it runs a compiled binary, whose bundled manifests we do not read, or none of the package.json, requirements.txt, pyproject.toml or uv.lock files it ships for its runtime declares a dependency we can read (a requirements.txt that only points at a setup.py project, a local path, or a nested requirements file we cannot follow counts as none).Unverified

Schema Quality & AI Usability65
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 2223 tokens (~202/item across 11 items; 11 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage82
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass

Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 11 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 12 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

Unverified: 2 categories
Categories scored 0 because we could not verify them: 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.
How do I install the SECONDED MCP server?
SECONDED 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, b356b76850d495ab7986c9281216a77a93715dfd39a59b4650e5c8400efec087; the commands to do that are on this page. If it does not match, do not open it.

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
seconded_agent_registry_check ~224
Use when: Before paying or trusting another agent that claims an ERC-8004 identity. Send: input with network, agent_id; claimed_owner, claimed_wallet, context optional. Answer → do: registered_with_feedback/registered_without_feedback: proceed with normal checks; other answers: STOP and show owner. NOT VERIFIED: pause or ask a human. Cost: $0.25 small only. New setups: $2.50 max per check, $25 a day; chat only tightens or freezes.
| Name | Type | Req | Description |
|---|---|---|---|
| input | object | yes | – |
| max_price_usd | string | – | Optional price ceiling in USD; required only when value gate is on (off for new setups). Cannot raise the owner-configured per-check limit (default $2.50), enforced before signing. |
| network | string | – | Chain you pay on. Omitted means base (Base mainnet). Other networks only when named: arc, robinhood, or testnets base_sepolia, arc_testnet, robinhood_testnet. |
| wait_seconds | integer | – | – |
No output schema declared.
No examples provided.
seconded_get_limits ~38
Show current per-check, hourly, daily and outstanding USD limits and safety switches. null means no user limit. Does not expose wallet keys.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
seconded_products ~30
Full guide: when to use each check, required inputs, labels and next steps, prices and examples.
Input schema present but exposes no named parameters.
No output schema declared.

seconded_receipt ~137
Recover a check or recent checks by fetching status only. With no check_id, lists the 20 newest checks and any older check still awaiting its receipt, newest first. A result's verification holds the receipt's signed findings and coverage. Never re-signs or re-sends a payment; may sign a read-only ownership proof. After any check error or timeout, call this before checking again. The answer wait can end while payment is pending: continue receipt-only recovery separately until final payment, certified nonpayment, or manual review. Certified nonpayment says not charged and permits retrying the check.

seconded_scam_check ~208
Use when: Before acting on an incoming message. Send: input with message. Answer → do: benign: proceed; suspicious: verify independently; malicious: STOP and show owner. NOT VERIFIED: pause or ask a human. Cost: $0.25/$1.50/$2.50 S/M/L. New setups: $2.50 max per check, $25 a day; chat only tightens or freezes.

seconded_set_limits ~489
Change spending limits at the user's request, without a password. For 'set my daily limit to $20', pass {"daily_usd":20}. Chat can only tighten limits or freeze. Any increase, removal, safety-switch weakening or unfreeze requires the human terminal. These changes require the owner to run the terminal command returned on refusal. There is an absolute $25/day chat ceiling, even when the owner has authorized a higher daily limit in the terminal. Omitted fields stay unchanged. The hard $2.50 per-authorization cap always applies, even if per_check_usd is higher or none. Also changes value_gate, dedupe, loop_brake, alerts and frozen switches.

Answer → do: official_stock_token: proceed with normal checks; not_official_or_out_of_line: STOP and show owner. NOT VERIFIED: pause or ask a human. Cost: $0.25 S only; larger inputs refused.

seconded_trade_check ~249
Use when: Before signing a trade, approval, transfer or permit. Checks: approval/signature scope. Send: transaction (unsigned tx) or typed_data (permit). Answer → do: proceed: sign exact input; do_not_proceed: STOP. NOT VERIFIED: pause. Re-check changes. Cost: $0.25/$1.50 S/M. Not for: The owner's words or rules; no launch check covers them.

seconded_wallet ~126
Show the dedicated check wallet address, balances per network and how to fund it, or freeze new authorizations. Wallet switching is terminal-only: seconded-mcp wallet --human --switch back (or newer). Both keys are preserved. Base funding normally becomes available after about a minute, when both readers agree on recent state; Robinhood also uses recent agreement. Final payment confirmation is separate. Pending amounts cannot fund checks yet. Unavailable balances are null, never assumed zero. Never returns a private key; export is a separate human-run CLI command.
